(Embodiment)
[Constitution]
First, the outline of the space proposal system according to the embodiment will be described. FIG. 1 is a block diagram showing a functional configuration of the space proposal system according to the embodiment. FIG. 2 is a diagram showing an outline of the space proposal system according to the embodiment.

The space proposal system 10 is a system for creating a floor plan of a building such as an apartment house or a detached house according to a customer's request. The space proposal system 10 may be used for planning the floor plan of a newly constructed building, or may be used for planning the floor plan of a building to be remodeled (in other words, renovated).

In general, the floor plan is planned by the planner, and the problem is that the quality of the planning differs depending on the personal skills of the planner. The space proposal system 10 is such a system for medium leveling the quality of planning.

As shown in FIGS. 1 and 2, the space proposal system 10 includes an input device 20, an information terminal 30, and a display device 40.

The input device 20 is a user interface device and includes a reception unit 21 that receives a planner's selection or input. The input device 20 is, for example, a keyboard or a mouse, and the reception unit 21 is a part of the input device 20 (for example, a hardware button).

The information terminal 30 is, for example, a personal computer. The information terminal 30 includes a control unit 31, a storage unit 32, and an output unit 33.

The control unit 31 performs information processing based on the input received by the reception unit 21. For example, the control unit 31 outputs display screen information to the display unit 41 of the display device 40 based on the input of the user received by the reception unit 21. As a result, the display unit 41 displays a display screen according to the user's input. Specifically, the control unit 31 is realized by a microcomputer. The control unit 31 may be realized by a processor.

The storage unit 32 is a storage device that stores an algorithm (a computer program executed by the control unit 31) used to generate the floor plan, various information used to generate the floor plan, and the like. Specifically, the storage unit 32 is realized by a semiconductor memory or the like.

The output unit 33 is an output interface device for outputting information from the information terminal 30 to an external device. Specifically, the output unit 33 is a communication module (communication circuit) for the information terminal 30 to communicate with an external device (for example, a printer). The communication performed between the information terminal 30 and the external device may be wired communication or wireless communication. The communication standard used for communication is also not particularly limited.

The display device 40 includes a display unit 41, and the display unit 41 displays a display screen based on the control of the control unit 31. Specifically, the display unit 41 displays the display screen based on the display screen information output by the control unit 31. Specifically, the display device 40 is a display including, for example, a liquid crystal panel or an organic EL panel as a display unit 41.

[motion]
Next, the operation of the space proposal system 10 will be described. FIG. 3 is a flowchart of the operation of the space proposal system 10.

First, the control unit 31 of the information terminal 30 causes the display unit 41 of the display device 40 to display the basic data input screen (S11). FIG. 4 is a diagram showing an example of a basic data input screen. When the basic data input screen is displayed, the reception unit 21 of the input device 20 accepts the basic data input operation (S12). As shown in FIG. 4, as the basic data, the subject, the submission destination, the delivery date, the production date, the person in charge, the proposal No., and the like are exemplified. The input basic data is stored in the storage unit 32 of the information terminal 30.

Next, the control unit 31 of the information terminal 30 displays a selection screen for selecting the number of rooms, the size of the rooms, and the occupied area desired by the customer (S13). When the selection screen is displayed, the reception unit 21 accepts selection of the number of rooms, the size of the rooms, and the occupied area (S14). FIG. 5 is a diagram showing an example of a selection screen.

On the selection screen of FIG. 5, the planner selects the number of rooms, the size of the rooms, and the occupied area in this order. Here, on the selection screen, when a certain item is selected, the selection of the next item is restricted. FIG. 6 is a diagram showing an example of such selection limiting logic. The limiting logic is stored in the storage unit 32 in advance, for example.

In the example of FIG. 6, there are four options for the occupied area: "50 m ² or less", "51 to 75 m ² ", "76 to 100 m ² ", and "101 m ² or more", and the room size options are , "Standard", "Luxury (large)", "Studio (very large)", and the choice of the number of rooms is "1" to "4"("1LDK" to "4LDK"). There are four. Specific numerical values may be input for the occupied area and the number of rooms.

When "3" is selected as the number of rooms, the column "3LDK" in FIG. 6 contains only two, "standard" and "luxury", so the room size options are: Of the three, it is limited to two, "standard" and "luxury". In other words, "studio" cannot be selected in the selection of room size, and the operation to the "studio" option becomes invalid. "Standard" is for customers who want the number of rooms that reflect the number of family members, "Luxury" is for customers who set the room size a little larger, and "Studio" is for customers who want to increase the size of the room. , For customers who want to eliminate corridors and utilize loose partitions.

If the selection of another option is restricted according to the selection or input result of one item in this way, it is possible to prevent the planner from creating an unrealizable (or unrealistic) floor plan. Will be done. In other words, the quality of the floor plan is leveled to the middle.

Further, the display unit 41 displays the options displayed on the selection screen in different modes depending on whether or not the options are selectable options, based on the control of the control unit 31. For example, selectable options are brightly activated and displayed, and non-selectable options are darkly grayed out. In the example of FIG. 5, "standard" and "luxury" are displayed brightly (white), and "studio" is displayed dark gray. This allows the planner to easily recognize whether or not the options are selectable.

For example, if "3" is selected as the number of rooms and then "standard" is selected as the size of the room, it corresponds to the row described as "standard" in the "3LDK" column of FIG. Only the occupied area can be selected. That is, the choice of occupied area is limited to two of the four, "51 to 75 m ² " and "76 to 100 m ² ". That is, in the selection of the occupied area, "50 m ² or less" and "101 m ² or more" cannot be selected. Also in this case, the display unit 41 displays the options displayed on the selection screen in different modes depending on whether or not the options are selectable options, based on the control of the control unit 31.

After selecting the number of rooms, the size of the rooms, and the occupied area as described above, the control unit 31 determines the rooms to be included in the floor plan (the floor plan to be proposed) based on the selection result in step S14. The breakdown and the size of the room included in the floor plan are determined (S15). 7A to 7C are diagrams showing a breakdown of the room and an example of the logic for determining the size of the room. The determination logic is stored in the storage unit 32 in advance, for example.

For example, when "3" is selected as the number of rooms, "standard" is selected as the size of the room, and "76-100 m ² " is selected as the occupied area, the floor plan at the bottom in the leftmost column of FIG. 7A, and , The size of the room is adopted. In the floor plan determination logic, each of the areas of the plurality of rooms included in the floor plan is determined based on the reference area according to the result of selecting the room size. The plurality of rooms here are, for example, a living room, an LDK, three points around the water (bath, washbasin, toilet), an entrance, and the like. In addition to rooms, the floor plan includes corridors, WIC (Walk In Closet), SIC (Shoes In Closet), pantry, and the like.

The reference area is, for example, A (5 tatami mats) when "standard" is selected as the size of the room, and in FIG. 7A, the size of each room, corridor, and storage is many times larger than A. It is expressed by. Similarly, the reference area is B (8 tatami mats) when "luxury" is selected as the size of the room, and in FIG. 7B, what is the size of each room, corridor, and storage of B? It is expressed in double. The reference area is C (10 tatami mats) when "Studio" is selected as the size of the room, and in FIG. 7C, the size of each room, corridor, and storage is several times larger than C. It is expressed.

When the size of each room, corridor, and storage is determined based on such determination logic, the control unit 31 generates a floor plan that combines each room, corridor, and storage, and displays the display unit. The floor plan generated in 41 is displayed in three dimensions (S16). FIG. 8 is a diagram showing an example of a display screen of the floor plan. The floor plan is automatically generated based on a predetermined algorithm, but may be manually generated by the planner.

At this time, the floor plan is generated as an aggregate of virtual building members (also referred to as blocks in the specification) prepared in advance. FIG. 9 is a diagram showing an example of a block used for generating a floor plan.

As shown in FIG. 9, the block is a basic block consisting of a ceiling material (C), a wall material (DW), a floor material (F), a partition wall material (W), a door (+ d), and a window (+ w). As a result, a block in which one or more of these basic blocks are combined is stored in the storage unit 32 in advance. The floor plan is generated as an aggregate of such blocks according to the above-mentioned predetermined algorithm, and in step S17, the control unit 31 together with the floor plan is a basic block necessary for realizing the floor plan. The quantity information of is generated and stored in the storage unit 32. FIG. 10 is a diagram showing an example of quantity information of a basic block.

In this way, if the floor plan is generated as an aggregate of blocks (basic blocks) that are virtual building members, and the quantity information of such basic blocks is also stored, it is easy to make an estimate described later. It becomes. Further, since the quantity information of the basic block is managed for each room included in the floor plan, it is possible to calculate the amount of money required to realize the room for each room as described later.

After step S16, the reception unit 21 accepts an operation for manually adjusting the floor plan as necessary (S17). FIG. 11 is a diagram showing an example of a display screen for manually adjusting the floor plan.

When the display screen of FIG. 11 is displayed, the planner can add optional spaces (for example, WIC, SIC, pantry, etc.), adjust the block size, and replace the blocks. For example, when replacing blocks, the blocks to be replaced are displayed at the bottom of the screen, and the blocks can be replaced by dragging and dropping them. When the reception unit 21 accepts an operation to change such a displayed block (building member) to another block, the display unit 31 sets the block to the floor plan being displayed based on the accepted operation. Reflect the changes.

Next, the control unit 31 calculates the amount of money required to realize the floor plan, and causes the display unit 31 to display the estimation information indicating the amount of money (S18). FIG. 12 is a diagram showing an example of a display screen of the estimated amount of the floor plan.

Specifically, the control unit 31 can calculate the amount of money required to realize the floor plan by integrating the unit price of the basic block × the quantity based on the quantity information of the basic block shown in FIG. it can.

In addition, the quantity information of basic blocks is managed for each room included in the floor plan. Therefore, the control unit 31 can calculate the amount of money required to realize the floor plan for each room included in the floor plan, and can calculate the estimated amount for each room. Which room to calculate the estimated amount of money is determined based on, for example, the room selection operation for the floor plan displayed in FIG. When the save operation is accepted by the reception unit 21, the estimation information is stored in the storage unit 32. Such estimation information can be printed by the output unit 33 outputting the estimation information to a printer connected to the space proposal system 10. At least a part of the basic data stored in step S12 is also used for the estimation information.

As explained above, the space proposal system 10 automatically generates a floor plan by selecting or inputting three pieces of information: the number of rooms, the size of the room, and the occupied area. Therefore, it is possible to generate a floor plan that does not rely on the personal skills of the planner. When selecting or entering the above three pieces of information, if one item is selected or entered, the selection of the next item will be restricted, and the planner will have an unrealizable (or unrealistic) floor plan. It is suppressed to create. In other words, the quality of the floor plan is leveled to the middle.

The planner can also manually adjust the automatically generated floor plan, and can adjust the size and position of the block according to the size of the entire floor plan. At this time, it is possible to add an option space and change (replace) the block.

Furthermore, the floor plan is an aggregate of blocks, and the space proposal system 10 can easily calculate the estimated amount based on the unit price of each block and the quantity of each block. Further, since the required number of blocks is managed for each room included in the floor plan, the space proposal system 10 can easily calculate the estimated amount for each room in conjunction with the generation of the floor plan. .. If the estimated price for each room is displayed, the customer can easily know how much it will cost for each room.

[Change the floor plan according to the future plan]
In addition, the space proposal system 10 displays a plurality of options for future plans assuming possible future events, and when the selection of future plans is accepted, the floor plan being displayed is automatically displayed based on the result of the selection. It can also be changed to. FIG. 13 is a diagram showing an example of a display screen for changing the floor plan according to such a future plan.

In the upper part of the display screen of FIG. 13, a plurality of future plan icons are displayed as a plurality of future plan options. Future plan icons include, for example, icons for children 1, children 2, pets, exams, private practice, and hobbies.

For example, when the reception unit 21 accepts the icon selection operation of the child 1, the control unit 31 assumes that a child will join the family in the future, and based on a predetermined algorithm, sets the child's room in the displayed floor plan. Add one.

In this way, the space proposal system 10 can also create a floor plan in consideration of the customer's future plan.

[Another example of selection screen]
The selection screen of FIG. 5 is a screen for selecting the number of rooms, the size of the rooms, and the occupied area in this order. Such a selection screen is an example. 14 to 16 are diagrams showing another example of the selection screen.

The selection screen of FIG. 14 is a selection screen for selecting in the order of occupied area, room size, and number of rooms, and the selection screen of FIG. 15 is in the order of occupied area, number of rooms, and room size. This is a selection screen for making a selection. The selection screen of FIG. 16 is a selection screen for selecting in the order of the number of rooms, the occupied area, and the size of the rooms. Further, although not shown, the selection screen may be a screen for selecting in the order of room size, occupied area, and number of rooms, or select in the order of room size, number of rooms, and occupied area. It may be a screen for performing.

In either case, based on the restriction logic as shown in FIG. 6, the selection of the second item is restricted according to the selection result of the first item, and the selection result of the first item and the second item is determined. The choices for the third item may be restricted.

[Effects, etc.]
As described above, the space proposal system 10 is based on the occupied area of the building, the number of rooms included in the building, the reception unit 21 that accepts the selection or input of the room size, and the accepted selection or input. It also includes a floor plan of the building and a display unit 41 that displays building members necessary for realizing the floor plan. The display 41 provides a plurality of options for the occupied area of the building, the number of rooms contained in the building, and the size of the room, the occupied area of the building, the number of rooms contained in the building, and , Selectable options and non-selectable options are displayed separately based on the result of at least one other selection or input of the size of the room. The building member is, for example, the block of the above embodiment.

According to the display method of such options, it is possible to prevent the planner from creating an unrealizable (or unrealistic) floor plan. In other words, the quality of the floor plan is leveled.

Also, for example, multiple choices for the occupied area of the building, the number of rooms contained in the building, and the size of the room, the occupied area of the building, the number of rooms contained in the building, and Based on the results of the other two selections or inputs of the size of the room, the selectable options and the non-selectable options are displayed separately.

If the options are displayed in this way, it is possible to prevent the planner from creating an unrealizable (or unrealistic) floor plan. In other words, the quality of the floor plan is leveled.

Further, for example, the reception unit 21 further accepts an operation of changing the displayed building member to another building member, and the display unit 41 adds the building member to the floor plan being displayed based on the accepted operation. Reflect the changes in.

This allows the planner to manually adjust the automatically generated floor plan.

Further, for example, the display unit 41 further displays the estimated information indicating the amount of money required to realize the floor plan for each room included in the floor plan.

If the estimated amount for each room is displayed in this way, the customer can easily know how much it will cost for each room.

Further, for example, the display unit 41 further displays a plurality of options for the future plan assuming possible events in the future, and when the reception unit 21 accepts the selection of the future plan, the display unit 41 is displaying based on the result of the selection. Change the floor plan.

Such a space proposal system 10 can create a floor plan in consideration of the customer's future plan.

Also, for example, each of the areas of a plurality of rooms included in the floor plan is determined based on the reference area according to the result of selecting the room size.

This simplifies the algorithm for determining the size of each room in the generation of the floor plan.

Further, for example, the space proposal system 10 further includes, for each of the plurality of rooms included in the floor plan, a storage unit 32 that stores quantity information indicating the quantity of building members required to realize the room.

If the quantity information is stored for each room in this way, the space proposal system 10 can easily calculate the estimated amount for each room.

Further, for example, a space proposal method executed by a computer such as the space proposal system 10 accepts selection or input of the occupied area of the building, the number of rooms included in the building, and the size of the room, and is accepted. Or, based on the input, display the floor plan of the building and the building materials necessary to realize the floor plan, and out of the occupied area of the building, the number of rooms included in the building, and the size of the room. Multiple choices for one, selectable choices based on the area occupied by the building, the number of rooms contained in the building, and the result of at least one other choice or input of room size, and , Display by distinguishing non-selectable options.
