  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a design support system 100A according to an embodiment of the present invention.

  In FIG. 1, a design support system 100A is connected to a CAD (Computer Aided Design) system 100B.

  The CAD system 100B is, for example, a three-dimensional CAD system, and includes a display unit 1, an input unit 2, an execution unit 3, and a storage unit 4. The CAD system 100B is not limited to a three-dimensional CAD system and can be changed as appropriate. For example, a two-dimensional CAD system may be used.

  The design support system 100 </ b> A includes a work history extraction unit 5, a storage unit 6, a state determination unit 7, a feature determination unit 8, and a support information determination unit 9. The work history extraction unit 5, the storage unit 6, and the state determination unit 7 are included in the determination unit 100A1. The determination unit 100A1 is an example of a determination unit. The feature determination unit 8 and the support information determination unit 9 are included in the control unit 100A2. The control unit 100A2 is an example of a control unit.

  The display unit 1 executes various displays. For example, the display unit 1 displays a feature designated by the user (for example, a graphic such as a square hole) and a pointer.

  The input unit 2 is, for example, a keyboard or a mouse. The input unit 2 receives various inputs from the user. For example, the input unit 2 receives work information representing work related to design from the user.

  The work information includes, for example, specific information for specifying a feature to be a work target (hereinafter referred to as “work target feature”) and a work instruction for instructing a work on the work target feature.

  As the specific information, for example, the selection result of the feature selected by the pointer in the display unit 1 is used.

  The work instructions include at least an “enlargement instruction” for enlarging the work target feature, a “reduction instruction” for reducing the work target feature, a “rotation instruction” for rotating the work target feature, A “creation instruction” for creating a target feature and a “deletion instruction” for deleting a work target feature are used.

  As a work instruction, a command may be used, or a result of operation with a mouse on a work target feature may be used.

  The execution unit 3 performs design by executing the work represented by the work information received by the input unit 2. Note that the technique in which the execution unit 3 performs the design represented by the work information and performs the design is a known technique, and thus detailed description thereof is omitted.

  The storage unit 4 stores a history of work performed by the execution unit 3 (hereinafter referred to as “work history”).

  FIG. 2 is a diagram showing an example of a work history.

  In FIG. 2, the work history 4a includes work data 4a0 for each work. In each work data 4a0, a work instruction 4a1 that is a source of work, a work target feature name 4a2, a center coordinate 4a3 of the work target feature, and a work time 4a4 are associated with each other.

  The work history extraction unit 5 monitors the storage unit 4. When new work data 4a0 is stored in the storage unit 4, the work history extraction unit 5 starts from a plurality of work data 4a0 in the storage unit 4a with a predetermined number n of work data in order from the work time 4a4 closer to the current time. 4a0 is read as determination work data. In the present embodiment, 4 is used as the predetermined number n. The predetermined number n is not limited to 4 and may be an integer of 2 or more. When the number of the plurality of work data 4a0 in the storage unit 4a is smaller than the predetermined number n, the work history extraction unit 5 reads all the work data 4a0 in the storage unit 4a. In the following, it is assumed that the work history extraction unit 5 has read four pieces of work data 4a0.

  The work history extraction unit 5 copies the determination work data whose work time 4a4 is closest to the current time among the four determination work data, and uses the copied determination work data as the latest work data. In addition, the four pieces of determination work data are output to the state determination unit 7 as extracted data.

  The storage unit 6 stores a determination condition for determining whether or not the user is in a state that requires support for design (hereinafter referred to as “support required state”). The support required state is an example of a predetermined state.

  As a determination condition, a condition that the user repeatedly performs a predetermined work is used.

  As the predetermined work, for example, a change work for changing the size of the same work target feature (the same work target figure) (hereinafter simply referred to as “change work”), or a rotation work for rotating the same figure ( Hereinafter, simply referred to as “rotation work”) is used. Note that the change work includes an enlargement work and a reduction work for the same work target feature.

  Further, as a predetermined work, a creation / deletion work including a creation work for creating a feature (figure) and a deletion work for deleting a feature (for example, a feature (figure (figure) created in accordance with the creation work)) is used. Good.

  In the present embodiment, the storage unit 6 stores three determination conditions 61 to 63. The judgment condition 61 is a condition that the change work is repeated. The determination condition 62 is a condition that the rotation work is repeated. The judgment condition 63 is a condition that the creation / deletion work is repeated.

  The state determination unit 7 determines whether the user is in a support-needed state based on the extracted data from the work history extraction unit 5.

  In the present embodiment, the state determination unit 7 is in a state where the user needs assistance when the work history represented by the extracted data includes a work history corresponding to any of the determination conditions 61 to 63 in the storage unit 6. Judge that there is.

  When the state determination unit 7 determines that the user is in a support-needed state, the state determination unit 7 outputs a detection signal indicating that the user is in a support-needed state to the feature determination unit 8.

  The feature determination unit 8 determines a feature (hereinafter, referred to as “factor feature”) that is a factor of the state requiring support. In this embodiment, when the feature determination unit 8 receives the detection signal from the state determination unit 7, the feature specified by the work target feature name 4a2 in the latest work data received from the work history extraction unit 5 Identify as a feature.

  The support information determination unit 9 outputs information on the factor feature specified by the feature determination unit 8 to the execution unit 3 as support information for supporting the design, and causes the execution unit 3 to display the support information on the display unit 1. Processing (hereinafter referred to as “display processing”) is executed.

  The support information determination unit 9 stores a support information list 9a used for specifying support information.

  FIG. 3 is a diagram showing an example of the support information list 9a.

  In FIG. 3, the feature name 9a1 and feature information (support information) 9a2 are associated with each feature in the support information list 9a.

  The feature information 9a2 represents information related to the feature, for example, know-how related to the design of the feature, information related to the feature, or a feature improvement plan.

  The support information determination unit 9 specifies the feature information 9a2 associated with the factor feature as support information, outputs the support information to the execution unit 3, and causes the execution unit 3 to execute display processing.

  Next, the operation will be described.

  FIG. 4 is a flowchart for explaining the operation of the design support system 100A.

  When receiving the work information from the user (step A1), the input unit 2 outputs the work information to the execution unit 3.

  When the execution unit 3 receives the work information from the input unit 2, the execution unit 3 executes the work represented by the work information and designs an article or the like (step A2).

  When executing the work represented by the work information, the execution unit 3 additionally stores work data representing the work in the storage unit 4 (step A3). For this reason, the work history (see FIG. 2) of the execution unit 3 is stored in the storage unit 4. In addition, since the execution part 3 performs work according to the work information from the user, the work history of the execution part 3 also represents the history of work intended by the user.

  The work history extraction unit 5 monitors the storage unit 4. When new work data is stored in the storage unit 4, the work time 4a4 is close to the current time from the work data 4a0 in the storage unit 4a. The four pieces of work data 4a0 are sequentially read out as judgment work data (step A4).

  When the work history extraction unit 5 reads out the four pieces of determination work data, the latest work data is created by copying the determination work data whose work time 4a4 is closest to the current time among the four pieces of determination work data ( Step A5).

  When the work history extraction unit 5 creates the latest work data, the work history extraction unit 5 outputs the latest work data to the feature determination unit 8 and outputs four pieces of determination work data to the state determination unit 7 as extracted data.

  When the state determination unit 7 receives the extracted data (four pieces of determination work data), the history of the work represented by the extracted data corresponds to one of the determination conditions 61 to 63 in the storage unit 6. It is determined whether a history is included (step A6).

  When the work history represented by the extracted data corresponds to any of the determination conditions 61 to 63 in the storage unit 6, the state determination unit 7 determines that the user is in a support-needed state (step A7). .

  On the other hand, when the work history represented by the extracted data does not correspond to any of the determination conditions 61 to 63 in the storage unit 6, the state determination unit 7 determines that the user is not in a support-needed state (step A8). ).

  The state determination unit 7 outputs a detection signal to the feature determination unit 8 when it is determined in step A7 that the user is in a support-needed state.

  When the feature determination unit 8 receives the detection signal, the feature determination unit 8 specifies the feature specified by the work target feature name 4a2 in the latest work data received from the work history extraction unit 5 as a factor feature (step A9).

  When the feature determination unit 8 specifies the factor feature, the feature name 4a2 of the factor feature, that is, the work target feature name 4a2 in the latest work data received from the work history extraction unit 5 is output to the support information determination unit 9. .

  When receiving the feature name 4a2 of the factor feature, the support information determination unit 9 specifies the feature information 9a2 (see FIG. 3) associated with the factor feature as the support information (step A10).

  When the support information determination unit 9 specifies the support information, the support information is output to the execution unit 3. The execution part 3 will perform the display process which displays support information on the display part 1, if support information is received (step A11).

  FIG. 5 is a flowchart illustrating an example of step A6 (determination as to whether the work history includes any of the determination conditions) illustrated in FIG.

  In FIG. 5, the state determination unit 7 indicates whether the work history represented by the extracted data represents the repeated scaling or rotation of the same work target feature, that is, the work represented by the extracted data. It is determined whether the history satisfies the determination condition 61 or 62 (step B1).

  When the work history represented by the extracted data represents repeated scaling or rotation of the same work target feature, the state determination unit 7 makes an effort to create a design idea for the work target feature. It is determined that the user is in a state requiring assistance (step A7).

  On the other hand, if the work history represented by the extracted data does not represent the repeated enlargement / reduction or rotation of the same work target feature, the state determination unit 7 determines that the work history represented by the extracted data is: It is determined whether the creation and deletion of the same feature is repeated, that is, whether the work history represented by the extracted data satisfies the determination condition 63 (step B2).

  If the history of work represented by the extracted data represents the repeated creation and deletion of the same feature, the state determination unit 7 is at a loss of design for the feature, or the feature It is determined that there is a trade-off between the design for and other conditions, and it is determined that the user is in a support-needed state (step A7).

  On the other hand, if the work history represented by the extracted data does not represent the repeated creation and deletion of the same feature, the state determination unit 7 determines that the user is not in a support-needed state (step A8).

  FIG. 6 is a flowchart showing an example of the process of step B1 shown in FIG.

  In FIG. 6, the state determination unit 7 determines whether S% or more of the work instructions 4a1 in the four determination work data constituting the extracted data is an “enlargement instruction” or a “reduction instruction” (step C1). S is 70, for example. Note that S is not limited to 70 and can be changed as appropriate.

  When S% or more of the work instructions 4a1 in the four determination work data is “enlargement instruction” or “reduction instruction”, the state determination unit 7 determines the center of the work target feature in the four determination work data. It is determined whether or not the center coordinate 4a3 having the first determination value X% or more of the coordinates 4a3 is within a certain range (step C2). The first determination value X is 70, for example. The first determination value X is not limited to 70 and can be changed as appropriate.

  When the center coordinates 4a3 equal to or greater than the first determination value X% are within a certain range, the state determination unit 7 determines that the user has repeatedly expanded and reduced the same work target feature, and the user It is determined that support is necessary (step A7).

  FIG. 7 is a diagram showing a part of an example of four pieces of determination work data when the user repeatedly creates and deletes the same work target feature. In FIG. 7, it is assumed that the center coordinates 4a3 of the work target feature are within a certain range.

  On the other hand, if the center coordinates 4a3 equal to or greater than the first determination value X% do not exist within a certain range, the state determination unit 7 indicates that the T% of the work instructions 4a1 in the four determination work data is “rotation instruction”. (Step C3). T is 70, for example. T is not limited to 70 and can be changed as appropriate.

  When T% or more of the work instructions 4a1 in the four determination work data is a “rotation instruction” or “reduction instruction”, the state determination unit 7 determines the center of the work target feature in the four determination work data. It is determined whether or not the center coordinate 4a3 having the second determination value Y% or more of the coordinates 4a3 is within a certain range (step C4). The second determination value Y is 70, for example. The second determination value Y is not limited to 70 and can be changed as appropriate. The second determination value Y may be the same value as the first determination value X or may be a different value.

  If the center coordinates 4a3 equal to or greater than the second determination value Y% are within a certain range, the state determination unit 7 determines that the user is repeating the rotation with respect to the same work target feature, and the user needs assistance. It is determined that it is in a state (step A7).

  On the other hand, if the center coordinates 4a3 equal to or greater than the second determination value Y% do not exist within a certain range, the state determination unit 7 determines that the user is not in a support required state (step A8).

  In step C1, if S% or more of the work instructions 4a1 in the four determination work data is not “enlargement instruction” or “reduction instruction”, the state determination unit 7 determines that the user is not in a support-needed state. (Step A8).

  In Step C3, if T% or more of the work instructions 4a1 in the four pieces of work data for determination are not “rotation instructions”, the state determination unit 7 determines that the user is not in a support-needed state (Step A8). .

  FIG. 8 is a flowchart showing an example of the process of step B2.

  In FIG. 8, the state determination unit 7 determines whether U% or more of the work instructions 4a1 in the four pieces of determination work data is a “creation instruction” or a “deletion instruction” (step D1). U is, for example, 70. U is not limited to 70 and can be changed as appropriate.

  When U% or more of the work instructions 4a1 in the four judgment work data is “creation instruction” or “deletion instruction”, the state judgment unit 7 performs the work target feature name 4a2 in the four judgment work data. It is determined whether or not the work target feature names 4a2 having the third determination value Z% or more are the same (step D2). The third determination value Z is 70, for example. The third determination value Z is not limited to 70 and can be changed as appropriate. The third determination value Z may be the same value as the first determination value X and the second determination value Y, or may be a different value.

  If the work target feature names 4a2 that are equal to or greater than the third determination value Z% are the same, the state determination unit 7 determines that the user has repeatedly created and deleted the same feature. Then, it is determined that the user is in a state requiring assistance (step A7).

  FIG. 9 is a diagram illustrating a part of an example of four pieces of determination work data when the user repeatedly creates and deletes the same feature.

  If the work target feature names 4a2 having the third determination value Z% or more are not the same, the center coordinates 4a3 having the fourth determination value W% or more out of the center coordinates 4a3 of the work target features in the four determination work data are constant. It is determined whether it exists within the range (step D3). The fourth determination value W is 70, for example. The fourth determination value W is not limited to 70 and can be changed as appropriate. Further, the fourth determination value W may be the same value as or different from the first determination value X, the second determination value Y, and the third determination value Z.

  When the center coordinates 4a3 of the fourth determination value W% or more exist within a certain range, the state determination unit 7 determines that the user has repeatedly created and deleted other features in a region around a certain feature, and the user Is determined to be in a state requiring support (step A7).

  If the center coordinates 4a3 equal to or greater than the fourth determination value W% do not exist within a certain range, the state determination unit 7 determines that the user is not in a support-needed state (step A8).

  In step D1, if U% or more of the work instructions 4a1 in the four judgment work data are not “creation instructions” or “deletion instructions”, the state determination unit 7 determines that the user is not in a support-needed state. (Step A8).

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the determination unit 100A1 determines whether the user is in a support-needed state based on the history of work performed by the CAD system 100B. The control unit 100A2 displays support information on the CAD system 100B when the determination unit 100A1 determines that the user is in a support-needed state.

  For this reason, when the user needs support information, the support information can be presented to the user.

  This effect is also exhibited by a design support system that includes the determination unit 100A1 and the control unit 100A2. FIG. 10 is a diagram illustrating a design support system including a determination unit 100A1 and a control unit 100A2.

  Further, in the present embodiment, the determination unit 100A1 determines that the user is in a support-needed state when the work history includes a repetition history of a predetermined work. In general, when a user repeats a predetermined work related to design, the user makes an effort to create a new idea related to the design, has a problem with the design, or trades with other design-related conditions. There is a high possibility that off-state occurs and the design is changed.

  For this reason, when the work history includes a history of repetition of a predetermined work, it is possible to improve the certainty of the determination by determining that the user is in a state requiring assistance.

  In the present embodiment, as the predetermined work, a work for changing the size of the same graphic or a work for rotating the same graphic is used. The operation of changing the size of the same graphic and the operation of rotating the same graphic are often repeated when the user is confused with the design. For this reason, when the operation | work which changes the size of the same figure or the operation | work which rotates the same figure is repeated, it will improve the certainty of the judgment by determining that a user is in a support required state. It becomes possible.

  In the present embodiment, as a predetermined work, a work including a creation work for creating a graphic and a deletion work for deleting the graphic is used. The task of creating and deleting is often repeated when the user is confused about the design. For this reason, when the work consisting of the creation work and the deletion work is repeated, it is possible to improve the certainty of the judgment by judging that the user is in the state of needing assistance.

  In the present embodiment, the control unit 100A2 displays information related to a graphic on which a predetermined operation has been repeatedly performed as support information on the CAD system 100B. There is a high possibility that the figure on which the predetermined work has been repeatedly performed is a factor that puts the user in a state of requiring support. For this reason, it is possible to present appropriate support information to the user by displaying, as support information, information regarding a graphic on which a predetermined operation has been repeatedly performed.

  In the present embodiment, the design support system 100A has been described as a system different from the CAD system 100B. However, the design support system 100A may be built in the CAD system 100B. For example, the design support system 100A and the CAD system 100B may be incorporated in the same PC. When the design support system 100A is a system different from the CAD system 100B, the design support system 100A and the CAD system 100B may be simply connected by a cable or connected via a network. Good.

  The design support system 100A may be realized by a computer. In this case, the computer reads and executes a program recorded on a computer-readable recording medium, and functions as the determination unit 100A1 and the control unit 100A2.

  In the embodiment described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.
