Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(Definition)

  In this embodiment, “furniture” widely includes housing equipment such as storage shelves, kitchen shelves, and unit baths. The members constituting the furniture are mainly made of wood, but are not limited to specific materials, and may be made of plastics, metal, stone, marble, or glass.

  In the present embodiment, “the circumscribed cuboid space” refers to the smallest virtual three-dimensional cuboid space that circumscribes the member. For example, if the member is a rectangular parallelepiped plate and the dimensions are 700 mm in length, 285 mm in width, and 15 mm in thickness, the space of the outline size of the plate is directly the circumscribed cuboid space of the member. In a non-cubic member such as a hinge fitting, the smallest rectangular parallelepiped space that can accommodate the fitting is the circumscribed rectangular parallelepiped space of the member. In the present invention, since furniture is assembled on a computer screen, members constituting the furniture are recognized and used as a circumscribed rectangular parallelepiped space. For convenience of explanation, in the embodiment of the present invention, when the term “plate material”, “metal fitting”, “surface material”, “core material”, “wooden material”, etc., these terms are used to mean the circumscribed cuboid space (part member space) of each member. There is also.

  In the present embodiment, the “part member” refers to a member constituting the unit, such as a plate material or a metal fitting. A plurality of part members usually constitute one unit, but there may be a case where one plate material alone constitutes a unit, such as a counter top plate or a shelf of a book shelf.

  In the present embodiment, the “part member space” refers to a space of a virtual three-dimensional cuboid that circumscribes the part member. The dimension of the part member space is normally set to be the same as the dimension of the part member if the part member is a rectangular parallelepiped shape. However, the dimension of the part member space can be set by reducing or expanding the dimension of the part member. For convenience of explanation, the term “plate material”, “metal fitting”, “core material”, “surface material”, “decorative material”, “part member”, and the like in the embodiments of the present invention may be used synonymously with their part member space. The surface of the part member space is associated with the surface of the other part member space to form a unit space.

  In the present embodiment, the “unit” refers to an article configured such that one or a plurality of part members such as a cabinet and a drawer are joined to perform a certain function. For example, the cabinet 100 shown in FIG. 4 is a single unit that can exhibit a storage function by joining five plate members, that is, left and right side plates, a base plate, a top plate, and a back plate. The shelf board 106 is a single unit composed of a composite board configured such that a core material and a decorative material are surface-associated with the core material. In the example of FIG. 4, the shelf plate 106 that is a unit is subjected to dowel processing and accommodated in a cabinet 100 that is another unit, and becomes a “shelf” of a book shelf.

  In this embodiment, the “unit space” refers to a virtual three-dimensional rectangular parallelepiped space circumscribing a unit composed of one or a plurality of part members. The unit space is defined by the surface association with the surface of the part member space of the part member constituting the unit. When the dimensions of the unit space are changed and input after the surface association, the dimensions of the part member space associated with the surface are changed in conjunction with each other. If the unit is a rectangular parallelepiped, the normal unit space is set to the same size as the unit. However, the unit space may be set as a rectangular parallelepiped space in which the size of the unit is enlarged or reduced. For example, when the shelf plate 106 is accommodated in the cabinet 100 in FIG. 3, instead of the shelf plate 106 (unit), a unit space in which the shelf plate 106 is slightly expanded in both lateral directions is associated with the cabinet accommodation space. By this, it is possible to give a space | interval required in order to insert a shelf board into a cabinet smoothly. For convenience of explanation, the term “unit” in the embodiments of the present invention may be used synonymously with the unit space.

  In this embodiment, for example, as shown in FIG. 13 (A), the “composite plate” refers to a case where a surface material such as a polyplywood is attached to the surface of the core material, and a wood material such as a tape is attached to the cut section. It refers to a plate material composed of a plurality of members. The “core material” refers to a target to which the “surface material” and the “wooden material” are attached. The surface material and the lip material attached to the core material are collectively referred to as “decorative material”. In the present invention, each of the core material, the surface material, and the mouthpiece material is a part member, and the space of these members is integrally joined by using a surface-related technique to form a single part member space. A "space". Thus, the space for the decorative material and the core material is set, and the space is associated with each other to form a part member space (composite board space), so that the design of furniture using the composite board can be made more efficient. Is possible. Furthermore, calculate the space of the “core material”, “surface material”, and “wooden material”, which are the minimum unit members that make up furniture, and join them using a surface association technique to create a “composite board”. By forming a unit space by associating the part member space with the other part member space as a part member space called "space", the component specification (BOM) of the smallest unit constituting the furniture is output. Is possible. For convenience of explanation, in the description of the embodiment of the present invention, the composite plate may be used synonymously with the circumscribed rectangular parallelepiped space (part member space) of the composite plate.

  In this embodiment, “product” refers to a furniture product created by combining a plurality of units. The unit for creating the product and the combination of the units can be set by sending data from the system of the embodiment of the present invention to the automatic manufacturing line of the furniture manufacturing factory. Alternatively, a combination may be made based on a design drawing at a furniture manufacturing factory.

  In this embodiment, “part member surface association” refers to associating one surface of a part member space with one surface of another part member space. A unit space can be configured by assigning surface associations to surfaces of a plurality of part member spaces. The method of associating the part member surfaces of the present invention is not necessarily limited to one. One method is to specify a distance between both surfaces of two parts member spaces joined to each other by capturing each parallel surface. If the distance between them is zero, both sides are on the same plane. For example, in FIG. 3, when considering the case where the plate member 106 is joined to the plate member 102 in the direction of the arrow, 1) the front surface 102B of the plate member 102 and the front surface 106B of the plate member 106 are parallel to each other, and If the distance is zero, and 2) the upper surface 102A of the plate material 102 and the upper surface 106A of the plate material 106 are parallel to each other, and the distance between both surfaces (0.5 mm in FIG. 3) is specified, the positional relationship between the two Is decided. As another method, referring also to FIG. 3, the joining position of one rectangular surface of the surfaces of the plate member 102 and the plate member 106 to be bonded to one rectangular surface of the other part member is set as one surface rectangle. It is possible to designate two sides extending from one corner as an origin by XY coordinates set as XY coordinates. Part member surface association is a rule to impose a restriction so that when a dimension change is input to one part member space, the dimensions of other part member spaces are changed according to the change input. You can also.

  In the present embodiment, “unit / part member surface association” refers to associating each of the six surfaces of the rectangular parallelepiped of the unit space with the surfaces of the part member spaces of the plurality of part members constituting the unit. By associating the six faces of the unit space with the faces of the multiple part member spaces that make up the unit space, when there is an input to change the dimensions of the unit space, the dimensions of the part member space are linked to it according to the setting of the face association. Can be changed.

  In the present embodiment, the “accommodating space” refers to a space in which all or a part of another unit can be accommodated inside the unit. In the example shown in FIG. 4, the cabinet 100 that constitutes the accommodation space P and the shelf board 106 that is accommodated in the accommodation space P are different units, and thus are not associated with each other. However, when shelves are stored in the cabinet, if a change to reduce the dimensions of the cabinet is input, the shelves cannot be accommodated in the cabinet unless the dimensions of the shelves are reduced and changed in conjunction therewith. By accommodating the unit space of another unit in the accommodation space of the unit on the accommodation side, it becomes possible to link the other to the change for one of the two different units.

  In this embodiment, “accommodating surface association” means that when a unit is accommodated in the “accommodating space” of another unit, the “accommodating space” of the other unit is “parent” and the accommodated unit is “child”. This means that the relationship of accommodation / accommodation is given by assigning the attribute. In the example illustrated in FIG. 4, the cabinet 100 is a parent unit, and the shelf plate 106 accommodated in the cabinet 100 is a child unit. By associating the unit space of the unit on the accommodating side with the unit surface of the unit on the accommodated side and the accommodating surface via the accommodating space, the latter unit space can be interlocked and changed in accordance with the change of the former unit space. It becomes possible. When the accommodated latter unit space is composed of a plurality of part member spaces, the dimensions of the part members are further changed in conjunction with each other.

  In the present embodiment, “machining” means that the machining registered in the memory is applied to the surface of the part member space. For example, referring to FIG. 8A, in order to support and fix the shelf board 106 in the cabinet 100, when a dowel is provided on the side face 106D of the shelf board and the right side board face 101C of the cabinet corresponding thereto, Dowel processing is selected and applied at a predetermined position specified by the rectangular XY coordinates. Further, referring to FIG. 8B, when the right side plate 101 and the top plate 104 are joined at an angle of 45 ° to each other, the top surface 101A of the right side plate 101 and the right side surface 104D of the top plate 104 are joined. Is cut at an angle of 45 °, joining as shown in FIG. 8B can be achieved. Furthermore, referring to FIG. 8C, it is also possible to select and apply a notch process to the corner of the shelf board 106. In this way, by registering the type / content of processing in the memory, and selecting the registered processing and assigning it to the position specified by the XY coordinates of the surface of the part member space, Various shapes of processing can be applied to desired positions.

  In this embodiment, “processing transfer” refers to transferring the processing applied to the position of one surface of a furniture part member to the position of the surface of another part member corresponding to the surface of the part member. Say. For example, in FIG. 8, when a dowel hole for supporting the shelf plate 106 is created on the inner side surface 101C of the right side plate 101 and the right side surface 106D of the shelf plate 106 corresponding thereto, the surface of 106D is used as a reference in its XY coordinates. At the specified position, the processing destination is designated as “self” and “partner”. In this case, “self” is the right side surface 106D of the shelf board 106, which is the reference surface. The “partner” is the left side surface 101 </ b> C of the right side plate 101. By enabling the processing applied to the position specified by the XY coordinates of the reference surface to be transferred to the XY coordinate position of another surface corresponding to the reference surface, the efficiency of furniture design can be greatly improved.

  FIG. 1 is an overall configuration diagram of a furniture design, order receiving, and manufacturing order system according to an embodiment of the present invention. In FIG. 1, a server 1 of a furniture design system is connected to a manufacturing factory 6 and a PC provided in a sales agent 4 or a house maker 5. Furthermore, the furniture design system 1 has a website 3.

The sales agent 4 or the house maker 5 proposes a product designed using the furniture design system 1 of the present invention to the customer 2 based on the PC or the catalog. Upon receiving a request for a change in size or specification from the customer 2, the sales agent 4 or the house maker 5 re-suggests an article designed by changing the size or specification along with its estimated price and delivery date. When a purchase order is received from a customer in the specification size and price storage period of the re-proposed product, the data is transmitted to the article design system server 1.
The furniture design system server 1 that has received the order calculates data necessary for manufacturing the ordered product based on the input data, and transmits the data generated by the calculation to the manufacturing factory 6 that is linked to the manufacturing. In addition to the above method, the customer can directly order without going through the sales agent or the house maker by accessing the website 3 set up by the custom-made furniture design system 1 and entering the goods of the desired size. Is also possible.

FIG. 2 shows an internal configuration of a furniture design system that is an embodiment of the present invention.
The system 1 includes a part member space creation input unit 11, a part member processing input unit 12, a unit space creation input unit 13, a unit space change input unit 14, an output display unit 15, an order reception unit 16, and a central processing unit (CPU). 17, a memory 18, and a manufacturing ordering unit 19. The system 1 can be operated from a PC connected to a server. The orderer 10 reads the data stored in the memory 18 and inputs the desired specifications using the part member input unit 11, the part member processing input unit 12, the unit space creation input unit 13, and the change input unit 14, The desired specification is subjected to arithmetic processing by the CPU 11, and the changed and designed product is displayed on the output display unit 15. The changed product is output and displayed as a three-dimensional image on the PC screen on the output display unit 15. The orderer 10 determines the order by checking the specifications of the displayed product and inputs the order from the order receiving unit 16. I can do it.

  The CPU 17 includes a circumscribed cuboid space calculation unit 17a, a part member surface association unit 17b, a unit space calculation unit 17c, a dimension change calculation unit 17d, and a machining information processing unit 17e. The circumscribed cuboid space calculation unit calculates a part member space by calculating a virtual three-dimensional circumscribed cuboid space of each part member, and assigns identification numbers to six faces of the cuboid of the calculated space. Based on the assigned identification number, each surface of one part member space is associated with each surface of another part member space. Further, the CPU 17 sets XY coordinates having six corners of the rectangular parallelepiped space as the origin and one corner of the rectangle constituting each surface as the origin, and two sides of the rectangle extending from the corner as the X axis and the Y axis. The position on the surface can be specified by the XY coordinates.

  The dimension change calculation unit 17c receives the change in the dimension of the part member space input by the unit space change input unit 14, and is the same as the surface of the part member space that is calculated by the circumscribed cuboid space calculation unit and assigned an identification number. Based on the surface association with the surface of the part member space of the part member that constitutes the unit, the dimension of the part member space that has been changed and associated with the unit space (unit / part member surface association) is linked to the change input. Let me change it.

  The processing information transfer unit transfers the processing data when processing data is input for processing performed on one surface of the part member by the part member processing data input means. The data of the article designed by these calculations is given a product number, sent from the CPU 10 to the memory 16 and stored therein.

  The memory 18 includes, for example, a hard disk storage medium, a RAM, or a ROM, and stores a part member registration master, changeable range data, and a product designed by an input unit and specified by a product number. The memory 18 further stores a program necessary for executing and outputting the operation of the present invention.

  When an order for a product designed by the present system is received from the order receiving unit 16, the manufacturing ordering unit 19 connected to the CPU 17 displays the component configuration details and processing details of the part member of the designed product for each unit and product. Prepared by classification and sent to the manufacturing factory 6 together with the product number. When the manufacturing factory 6 wishes, a design drawing is sent. This system 1 sends the manufacturing data to the manufacturing factory 6 without printing out the six-sided drawings of the products designed and ordered according to the customer's wishes, and the manufacturer draws the design drawings in his / her own style. It is also possible to print out.

Example 1
FIG. 4 shows a bookshelf designed using the system of the embodiment of the present invention. FIG. 5 is a diagram illustrating the cabinet of the book shelf of FIG. FIG. 6 shows part member surface association in the cabinet of FIG. FIG. 7 shows unit / part member surface association in the cabinet of FIG.

1. Units and parts <Product configuration>
The book shelf in FIG. 4 includes a cabinet (unit 1) and a shelf (unit 2).
The part members of the unit 1 include a right side plate 101 (with dowel hole processing), a left side plate 102 (with dowel hole processing), a back plate 103, a top plate 104, and a base plate 105.
The part member of the unit 2 includes a shelf board 106 (with dowel hole processing) and dowels 107 (four).

2. Unit creation <Cabinet creation>
Step 1) Create a cabinet.
A board is formed on the screen by reading the data of the board registered in the memory, dragging and moving the read board on the screen, and adjusting the position / dimension. In the example of FIG. 5, the cabinet 100 includes five plate members (the right side plate 101, the left side plate 102, the back plate 103, the top plate 104, and the ground plate 105).

Step 2) The unit 1 is created by giving the part member surface association between the plate members.
First, in order to make a surface association between plate members (part members) constituting the cabinet, the CPU automatically assigns identification codes to the six surfaces of the rectangular parallelepiped of each plate member. Assuming that the upper surface is the A surface, the front surface is the B surface, the left surface is the C surface, the right surface is the D surface, the bottom surface is the E surface, and the rear surface is the F surface, 101A, 101B, 101C, 101D, 101E, 101F, 6 surfaces of left side plate 102 are 102A, 102B, 102C, 102D, 102E, 102F, 6 surfaces of back plate 103 are 102A, 102B, 102C, 102D, 102E, 102F, 6 surfaces of top plate 104 104A, 104B, 104C, 104D, 104E, 104F, and identification codes 105A, 105B, 105C, 105D, 105E, 105F are assigned to the six surfaces of the main plate 105.

As a surface association procedure, for example, in the example of FIG. 5, surface association is started using the left side plate 102 as a reference as follows.
1. The right side surface 102D of the left side plate 102 and the left side surface 104C of the top plate 104 are parallel to each other and on the same plane.
2. The right side surface 102D of the left side plate 102 and the left side surface 105C of the base plate 105 are parallel to each other and on the same plane.
3. The left side surface 102C of the left side plate 102 and the left side surface 103C of the back plate 103 are parallel to each other and on the same plane.
4). The front surface 102B of the left side plate 102 and the front surface 101B of the right side plate 101 are parallel to each other and on the same plane.
5. The front surface 102B of the left side plate 102 and the front surface 104B of the top plate 104 are parallel to each other and on the same plane.
6). The front surface 102B of the left side plate 102 and the front surface 104B of the ground plate 105 are parallel to each other and on the same plane.
7. The rear surface 102F of the left plate 102 and the rear 101F of the right plate 101 are parallel to each other and on the same plane.
8). The rear surface 102F of the left side plate 102 and the rear surface 104F of the top plate 104 are parallel to each other and on the same plane.
9. The rear surface 102F of the left side plate 102 and the rear surface 105F of the ground plate 105 are parallel to each other and on the same plane.
10. The rear surface 102F of the left plate 102 and the front surface 103B of the back plate 103 are parallel to each other and on the same plane.
11. The upper surface 102A of the left side plate 102 and the upper surface 104A of the top plate 104 are parallel to each other, and 102A is separated from 104A by 0.5 mm.
12 The upper surface 102A of the left side plate 102 and the upper surface 101A of the right side plate 101 are parallel to each other and on the same plane.
13. The lower surface 102E of the left side plate 102 and the lower surface 105E of the base plate 105 are parallel to each other, and 102E is separated from 105E by 0.5 mm.
14 The lower surface 102E of the left side plate 102 and the lower surface 101E of the right side plate 101 are parallel to each other and on the same plane.
15. The upper surface 102A of the left side plate 102 and the upper surface 103A of the back plate 103 are parallel to each other and on the same plane.
16. The lower surface 102E of the left side plate 102 and the lower surface 103E of the back plate 103 are parallel to each other and on the same plane.

Since the left side plate 102 is not directly adjacent to the right side plate 101, the cabinet 100 cannot be completely defined only by plane association with the left side plate as a reference. Therefore, after completing the surface association started with the left side plate as a reference, the right side plate 101 and the back plate 103, the top plate 104, and the ground plate 105 are associated with each other as follows.
17. The left side surface 101C of the right side plate 101 and the right side surface 104D of the top plate 104 are parallel to each other and on the same plane.
18. The left side surface 101C of the right side plate 101 and the right side surface 105D of the ground plane 105 are parallel to each other and on the same plane.
19. The right side surface 101D of the right side plate 101 and the right side surface 103D of the back plate 103 are parallel to each other and on the same plane.
FIG. 6 shows the part member surface association given according to the above. The circumscribed rectangular parallelepiped of the cabinet 100 created by associating the part member surfaces with the respective plate materials (part members) is referred to as a unit 1.

Step 3) A unit / part surface association is given between each of the six surfaces (A, B, C, D, E, F) of the unit 1 created as described above and each part member constituting the unit 1.
1. The upper surface (A surface) of the unit 1 is parallel to the left plate upper surface 102A and the distance between the surfaces is zero.
2. The lower surface (E surface) of the unit 1 is parallel to the left plate lower surface 102E, and the distance between the surfaces is zero.
3. The left side surface (C surface) of the unit 1 is parallel to the left side surface 102C of the left side plate 102, and the distance between the surfaces is zero.
4). The right side surface (D surface) of the unit 1 is parallel to the right side plate right surface 101D and the inter-surface distance is zero.
5. The front surface (surface B) of the unit 1 is parallel to the front surface 102B of the left plate and the distance between the surfaces is zero.
6). The rear surface (F surface) of the unit 1 is parallel to the back plate rear surface 103F, and the distance between the surfaces is zero.

  FIG. 7 shows the unit / part member surface association between the unit 1 (cabinet 100) thus created and each part member. In the examples shown in FIGS. 5 to 7, the cabinet 100 is created by starting the surface association from the left side plate as a reference and assigning the surface association with the right side plate that cannot be surface-related. However, the surface association procedure for creating the cabinet 100 is not limited thereto, and other methods may be used as long as a unit can be defined.

  Furthermore, in FIG. 5 to FIG. 7, the cabinet 100 created by providing the surface association between the five part members is referred to as the unit 1. However, as a procedure for defining the relationship between the unit and the part member, the cabinet 100 is configured by first dragging and moving the five plate members on the screen without associating the part member surface. A rectangular parallelepiped of the cabinet can be referred to as a unit 1, and each of the six surfaces of the unit 1 can be associated with a surface of a plate member (part member). Specifically, in the example of FIG. 4, the six A surfaces of the cabinet 100 are the 102A surface of the plate material 102, the B surface is the 102B of the plate material 102, the C surface is the 102C of the plate material 102, and the D surface is the plate material 101. The 101D surface and the E surface are associated with the 102E surface of the plate material 102, and the F surface is associated with the 102F surface of the plate material 102. However, with this method, it is difficult to set fine positions such as dust between the parts.

  In the above, the method of manually assigning surface associations one by one was explained to explain the surface association. However, it is not always necessary to manually assign all the surface associations of each surface one by one. If the minimum necessary surface association is entered, the surface association can be given by automatic calculation by the CPU. However, once a standard unit is created by associating a surface, it can be reused by copying the unit, so even if the initial surface association is given manually, the actual operation can be performed. It is not a big burden.

Step 4) After completing the above-described surface association and processing assignment for assigning the parent attribute, the “parent” attribute is assigned to the unit of the cabinet 100. By assigning the parent attribute, the cabinet 100 can accommodate another unit having the “child” attribute in the accommodation space.

<Create shelf board>
Step 5) A shelf board 106 is created.
In the present embodiment, a shelf board 106 is created by reading out from the memory a composite board in which the end material of the core material shown in FIG. In the composite plate shown in FIG. 13A, a surface material is attached to two upper and lower surfaces of a core material, and a mouthpiece material is attached to four surrounding surfaces. The surface of the core material space and the surface of the surface material space are associated with each other (part member surface association) to form a composite plate space.

  With reference to FIG. 9 and FIG. 13, the width dimension of the composite plate is set to 420 mm in the surface association of the core material, the end piece, and the composite plate. As shown in FIG. 13B, the composite plate is changed so that the end piece is not attached to the right end surface. As a simple method for the change, it is possible to change the thickness of the end piece of the right end face to zero. In this case, since the width dimension of the composite plate is set in association with the part member surfaces so as to be kept constant, the width dimension (419 mm) of the core material and the surface material is the thickness dimension (0. 5mm) is increased to 419.5 mm.

  Similarly, referring to FIG. 9 and FIG. 13, the thickness dimension of the composite plate is set to 15 mm in the surface association between the core material and the surface material. As shown in FIG. 13C, the upper surface is changed so as not to attach the surface material. As a simple method for the change, it is possible to change the thickness of the upper surface material to zero. In this case, since the thickness of the composite plate is set to maintain 15 mm in the surface association, the thickness dimension (12.5 mm) of the core material and the lower surface material is equal to the thickness dimension (2 of the deleted upper surface material). .5 mm) and is increased to 15 mm.

  In the following steps, description will be made assuming that a composite plate having the configuration shown in FIG.

Step 6) Dowel processing is given to the shelf board 106.
In the present embodiment, dowel processing means that dowel holes are formed at positions corresponding to both inner side surfaces of the cabinet and both outer side surfaces of the shelf board 106 in order to provide shelves at a certain height inside the cabinet. In addition, it refers to a process of inserting a small substantially cylindrical dowel material into the created dowel hole. In the present embodiment, the dowel processing is given at least four places necessary for supporting and fixing the shelf in the cabinet.

  Referring to FIG. 8 (A), XY coordinates are set with the lower left corner of the right side surface 106D of the shelf board 106 as the origin and the two sides extending therefrom as the X axis and the Y axis, and the dowel holes a and b are defined. Specify the XY coordinate position of the processing position. In FIG. 8, the coordinate position of a is (54 mm, 7.5 mm), and the coordinate position of b is (234 mm, 7.5 mm). Next, at that position, a processing input instruction is input by the processing input means. When inputting a processing giving instruction, dowel hole processing is selected as the processing type, and the processing destination is designated as “self” and “partner”. Then, since the right side surface 106D of the shelf board 106 corresponds to the “self” of the processing destination, dowel hole processing is given to the coordinate positions of 106D a and b. At this time, since the shelf is not yet installed in the cabinet, no processing is given to the “partner”.

  Similarly, an XY coordinate is set with the lower left corner of the rectangle on the left side surface 106C of the shelf plate 106 as the origin, an XY coordinate position of a position to which the dowel hole machining is applied is designated, and the dowel hole machining is performed at the coordinate position. When an instruction to process is input as “self” and “partner”, a dowel hole is provided in the shelf board left side surface 106C. At this time, since the shelf is not yet installed in the cabinet, the processing for the “partner” (102D surface) is not given.

Step 7) Assign child attributes.
The installed shelf board 106 is a single unit by itself, and is given a “child” attribute because it is used as a shelf for a book shelf after being subjected to dowel processing.

3. Combining units to make a product.
Step 8) Storing the shelf in the cabinet As shown in FIG. Drag to the position where you want to install.

  The inner surface of the accommodation space P defined by the side plates 101 and 102, the top plate 104, the base plate 105, and the back plate 103, which are part members of the cabinet 100, is accommodated in the space, and the shelf board 106 is surrounded by the inside. Since the four surfaces (B surface, C surface, D surface, F surface) are inscribed in the accommodation space P, the four surfaces are associated with each other. Based on the assignment of the “parent” attribute to the cabinet 100 and the assignment of the “child” attribute to the shelf board 106, the shelf board 106 is assigned an accommodation association via the cabinet 100 and the accommodation space P.

  In the example of FIG. 4, when the storage planes are associated with each other at the position where the shelf 106 is dragged and moved, the above-described storage plane is based on the parent attribute given to the cabinet and the child attribute given to the shelf. The accommodation relationship between the cabinet 100 and the shelf board 106 is set according to the setting of association.

  When the shelf plate 106 is accommodated in the housing space of the cabinet, it is specified that the dowel processing applied to the 106D surface of the shelf plate 106 is also applied to the “partner”, so the dowel processing is performed on the right side surface 106D of the shelf plate 106. Is transferred to the corresponding XY coordinate position of the surface of 101C facing in parallel.

Step 9) Entering Unit Dimension Change An operation for changing the height 700 mm of the cabinet 100 (unit 1) by 10 mm and changing it to 690 mm will be described with reference to FIGS.
In FIG. 7, since the upper surface (A surface) of the unit 1 is associated with the left-side plate upper surface 102A and the unit / part surface, if the height of the unit 1 is 690 mm, the relationship that the left-side plate 102A surface is set by surface association (both The distance between them is moved 10 mm downward in conjunction with it according to zero). Then, referring to FIG. 6, the upper surface 104A of the top plate 104 is associated with the upper surface 104A of the top plate 104 in parallel with each other at a setting of 0.5 mm away from the upper surface 104A of the top plate 104. While maintaining the relationship of being 0.5 mm away from the surface of the plate 102A, it is lowered 10 mm downward. Further, the left side plate upper surface 102A is associated with the upper surface 101A of the right side plate 101 and the upper surface 103A of the back plate 103 at a distance of zero, so that when the left side plate upper surface 102A is moved downward by 10 mm, it interlocks with it. The right side plate 101A surface and the back plate 103A surface are also moved downward by 10 mm. As a result, the height dimension of the part members 101, 102, and 103 is reduced by 10 mm in accordance with the input of changing the height of the unit 1 to 690 mm, so that all become 690 mm.

  Next, an operation for changing the width of the cabinet 100 (unit 1) from 400 mm to 500 mm will be described with reference to FIGS.

  In FIG. 7, the right surface (D surface) of the unit 1 is associated with the right side plate right surface 101D and the unit / part member surface. Therefore, when the lateral width of the unit 1 is changed to 500 mm, the right side plate 101D surface is set by the surface association. In accordance with (the distance between the two is zero), it is moved 100 mm rightward in conjunction with each other. Then, in FIG. 6, since the right side surface 101D of the right side plate 101 is surface-associated with the right side surface 103D of the back plate 103 with a setting of zero distance from each other, the right side surface 101D of the right side plate 101 is moved 100 mm in the right direction. Assuming that the lateral width of the unit 1 is 500 mm, the back plate right side surface 103D moves to the right by 100 mm while maintaining the relationship that the inter-plane distance with the 101D is zero.

  Further, since the right side plate 101 is 101C, which is the back side of the right side surface 101D, associated with the right side surface 104D of the top plate 104 and the right side surface 105D of the ground plate 105, when the right side plate 101 is moved in the right direction, In addition to the surface association between 101D and 103D, the surface association between 101C and 104D and between 101C and 105D is also related.

  When the position of the surface is moved 100 mm to the right side with respect to the right side surface (D surface) of the unit 1, the right side plate 101 has a constant thickness, so the left side surface 101 C of the right side plate 101 also moves 100 mm to the right. Referring to FIG. 6, 101C is associated with the right side surface 104D of the top plate and the right side surface 105D of the main plate 105, so that 104C is linked with 101C according to the relationship set there (the distance between the two is zero). Both 105Ds are moved 100mm to the right. As a result, by changing the width of the unit 1 from 400 mm to 500 mm, the width dimensions of the top plate 104, the base plate 105, and the back plate 103 are increased by 100 mm in association with the change to 500 mm.

  Furthermore, when the dimensions of the unit 1 are changed, the dimensions of the accommodation space P constituted by the right side plate 101, the left side plate 102, the back plate 103, the top plate 104, and the base plate 105 are 659 mm high, 470 mm wide, and 285 mm deep. Be changed. If it does so, the dimension of the rectangular parallelepiped of the shelf board 106 which inscribed in the accommodation space P of the unit 1 and was given the attribute of a child will be changed in conjunction according to accommodation surface association.

  Furthermore, with reference to FIG.5, FIG.6, FIG.7, FIG.8 and FIG. 10, operation which moves the position of the shelf board 106 accommodated in the cabinet 100 (unit 1) to a position lower 10 mm is demonstrated.

  In FIG. 8, the shelf plate 106 has a bottom surface 106 </ b> E installed at a distance of 323.5 (331 mm-7.5 mm) from the bottom surface 101 </ b> E of the right side plate 101. Between the right side plate 101 and the shelf plate 106, the 101C surface is set to be the 106D surface, the 101B surface is set to the 106B surface, the 101F surface and the 106F surface are parallel to each other, and the distance between the surfaces is set to zero. However, since the distance between the 101A surface and the 106A surface, and between the 101C surface and the 106C surface is not specified in the surface association, the distance between each other can be freely changed. The bottom surface 106E is moved 10 mm downward so that the distance from the bottom surface 101 of the bottom surface 106E becomes 321 mm. Then, as shown in FIG. 10 (B), the XY coordinates where the positions of processing a, b, c (transfer from 106C) and d (transfer from 106C) applied to the 106D and 101C surfaces are set to the 101C surface. Above, each Y coordinate is lowered by 10 mm.

Step 10) Calculate and display the specifications, estimated price and delivery date of the designed bookshelf.
The price and delivery date estimate of the bookshelf designed through the dimension change in step 9) is calculated based on the members constituting the bookshelf and the procurement period, and the result is displayed on the PC screen together with the designed bookshelf. To do.

  FIG. 15 is an example of the master data of the price and the procurement period of the members used for the bookshelf of this embodiment. The prices and lead times for individual parts are presented from the manufacturing plant 6 of FIGS. 1 and 2 and stored in the memory 18 of FIG.

  In this embodiment, the estimated price of the product is based on the price of each member registered in the master data of the part member, and the estimated price of the book shelf is integrated with the price of the part member used for manufacturing the product. Calculated by adding wages. The delivery date of the product is based on the time required for procurement of each member registered in the master data of the parts material, and the delivery time of the bookshelf is the one with the longest procurement period among the multiple parts materials used for manufacturing the product. Calculate based on

Step 11) The customer is inquired whether the product dimensions, estimated price, and delivery date are OK.
A book shelf with dimensions changed by a change input to the unit is output and displayed on the PC screen as a stereoscopic image. If the customer is satisfied with the specifications, estimated price, and delivery date of the product output on the screen, the customer decides to purchase the proposed furniture. If the displayed specification, price, or delivery date is not satisfied and a correction is desired, the process returns to the change input in step 9).

  In the system of this embodiment, it is not specified whether an adhesive or a nail is used as a joining means between the part members. They can be set and given as processing for the part member. Alternatively, the method of joining the part members can be left to a manufacturing factory that cooperates with the manufacturing without specifying it in the system of the present invention.

4). Order product manufacturing.
Step 12) Send the manufacturing data of the product ordered by the customer to the manufacturing factory.
