Luxurious as an adjective that describes a feeling.

Evaluation terms such as spacious and spacious, knowledge that defines the relationship between evaluation terms, knowledge that defines the relationship between these evaluation terms and housing design elements, etc. are stored as a knowledge database, and humans can use evaluation terms like a keyboard. By operating the input means, for example, input a limited term for housing design such as ``Japanese-style room'', which represents a design element that is a component of a house, and ``spacious'', which represents the feeling you have of a Japanese-style room. When an evaluation term .degree.

Problems to be Solved by the Invention Generally, the taste of adjectives that express feelings as input evaluation terms change over time. For this reason,
The input evaluation term and the design element displayed on the display means may not match the image of the person who input the evaluation term.

Means for solving the problem The evaluation terms input by operating the evaluation term input means,
A design device that infers and extracts optimal design elements from a knowledge database and displays the extracted design elements on a display means, the design device inferring and extracting optimal design elements from a knowledge database by specifying a modification location of the design element displayed on the display means. A design modification means is provided for extracting another design element at the modified location and displaying it in place of the design element at the specified modification location.

When an operator inputs an evaluation term by operating the evaluation term input means, an optimal design element is inferred and extracted from the knowledge database, and the display means displays this design element. If the design element displayed on the display means does not match the image of the input evaluation term, the operator specifies a correction point, and the design correction means selects another design element at the correction point from the knowledge database. The extracted design element is extracted and the display means displays the design element in which only the specified modification part has been changed.

Embodiment As shown in FIG. 1.2, this embodiment roughly comprises an evaluation term input means I, a knowledge database 2, a design selection means 3, a display means 4, and a design modification means 5. Since this is an example of the case where the interior design of a vehicle interior is performed using Combicota Graphic, the evaluation term input means 1 is composed of a keyboard, which is a computer input means, and the knowledge database 2, the vehicle design selection means 3, and the design The correction means 5 is constituted by a computer main body, and the display means 4 is constituted by a CRT which is an output means of the computer.

Here, the knowledge database 2 has evaluation terms 2゜ (Table 1 below)
), knowledge that defines the relationship between evaluation terms 21 (see Table 1 below), and vehicle design elements 22 as design elements.
(See Table 2.3 below).

Knowledge that defines the relationship between evaluation terms and vehicle design elements 2
3 (see Table 2 below), modified evaluation term 25°, satisfaction evaluation term 26. It is constructed by storing each of the intention expression terms 27 in at least the memory M of the computer.

The evaluation terms 20 are composed of adjectives as shown in the example evaluation terms in Table 1 below.

As shown in Table 1 below, the knowledge 21 that defines the relationship between evaluation terms is obtained by dividing the evaluation terms 20 into factors 1 to 10 using multivariate analysis such as quantification logic class I or ).

The vehicle design elements 22 are classified into first to fifth items as shown in Table 2 below.

Knowledge that defines the relationship between evaluation terms and vehicle design elements 2
No. 3 was prepared as a result of a sensory evaluation experiment as shown in Table 2 below. Specifically, the evaluation terms 20 and the first to fifth items of the vehicle design elements 22 are selected, the vehicle design elements 22 corresponding to the first to fifth items are shown to a large number of unspecified people, and the adjective words The feelings received from the vehicle design elements 22 for each of the evaluation terms 20 that are a group are collected, and the collected results are subjected to multivariate analysis such as quantification logic type I or type II to calculate partial regression coefficients (correlation It is analyzed as a number).

Here, the first item is provided on the instrument panel in the vehicle design element 22, as shown in Table 2.
The focus is on the number of meters, which is classified into the first to fifth categories. The first category of this first item is one with one large meter. The second category of the first item includes one large meter and two small meters. The third category of the first item has one large meter and three small meters. The fourth category of the first item has two large meters and one small meter. The fifth category of the first item has two large meters and two small meters.

The second item is the “instrument panel and meter cluster” in the vehicle design elements 22, as shown in Table 2.
This is divided into the first category and the second category.

The first category of this second item is one in which an instrument panel and a meter cluster are integrated. The second item, the second category, is one in which the instrument panel and meter cluster are separated.

As shown in Table 2, the third item focuses on the "meter cluster and center console" among the vehicle design elements 22, and is divided into the first category and the second category. The first category of this third item is one in which the meter cluster and center console are integrated. The second category of the third item is one in which the meter cluster and center console are separated.

As shown in Table 2, the fourth item focuses on "door thickness" in the vehicle design elements 22, and is classified into the first category and the second category. The first category of items is those with thick doors.The second category of items is those with thin doors.

As shown in Table 2, the fifth item focuses on the "overhang of the center cluster" among the vehicle design elements 22, and is classified into the first category and the second category. The first category of this fifth item is one in which the center cluster has an overhang. The second category of the fifth item is one in which the center cluster does not have an overhang.

The design selection means 3 is programmed in advance as a system base in the memory M of the computer, and uses the evaluation term 20 input by key operation of the evaluation term input means 1 to cause the CPU of the computer to operate according to the flowchart shown in FIG. Then, the optimum vehicle design element 22 is inferred and extracted from the knowledge database 2 and displayed in the design display area 40 of the display means 4.

The design modification means 5 is programmed in advance as a system base in the memory M of the computer, and the vehicle design elements 22 are displayed on the display means 4 by operating a cursor using the evaluation term input means 1 or by operating a mouthpiece or light ben (not shown). By specifying the modification location, the CPtJ of the computer extracts an item as a vehicle design element name corresponding to the modification location from the knowledge database 2 according to the flowchart shown in FIG. message display area 41
At the same time, when the operator expresses his/her intention with "OK" in response to the message displayed in the message display area 41, another vehicle design element 22 at the modified location is extracted, and this is added to the vehicle design element at the designated modified location. Displayed instead of element 22.

According to the above embodiment structure, first, evaluation terms 2'0. Knowledge defining relationships between evaluation terms obtained in preliminary experiments 21. Vehicle design elements 22, knowledge 23 that defines the relationship between evaluation terms obtained through sensory experiments and vehicle design elements, and modified evaluation terms 25. Satisfaction evaluation term 26.
Intention expression terms 27 and the like are stored in the memory M of the computer.

In this state, when a human operates the evaluation term input means 1 to input an adjective as the evaluation term 20, the design selection means 3 uses the CPU of the computer to select the optimal vehicle design element 22 from the knowledge database 2 through adjective processing. Infer and extract.

Here, we assume that the evaluation term 20 is “degree suitable for runners,”
The above operation will be specifically explained based on the flowchart shown in FIG.

In step 101, if "for runners" is input as the evaluation term 20, which expresses the feeling that humans have, the evaluation term 2° most closely related to the input evaluation term 20 is selected from Table 1 in step 102. do. 20 evaluation terms selected from Table I (input evaluation terms “
(same as ° for runners) is “suitable for runners”, and as indicated by the “△” mark in the notes of Table 2 in step 103,
Evaluation J7] The word column “suitable for runners” and the corresponding partial regression coefficient are extracted as shown in Figure 3 below (Table 3 is similar to Table 2).
(same as those marked with “△” in the notes).

Then, in step +04, the first partial regression coefficient among the partial regression coefficients for the first to fifth items shown in Table 3 (the partial regression coefficient corresponding to the part marked with "○" in the lower column of Table 3) is selected. The vehicle design element 22 of the corresponding category is extracted from the knowledge database 2, and is displayed as an image in the design display area 40 of the display means 4 in step 105.
At step 06, the operator is asked whether the displayed image on the display means 4 is satisfactory. And if the operator is satisfied, step 1
In step 07, the satisfaction evaluation term 26 is input into the knowledge database 2, and in step 108, the design is displayed! The cycle ends.

Next, if the operator who visually recognized the two-leg display image is not satisfied with the evaluation term 20 input in step +01 and feels that it does not match the feeling of ``suitable for runners'', step 109 When you specify the correction area by operating the cursor using the evaluation term input means 1 or by operating the mouthpiece or light pen (not shown), the design correction means 5
Step 1
11 steps explained in 10! Extract from the knowledge database 2 a word representing an item as a vehicle design element name corresponding to the modification point specified in step 09 (step 5 displays the word in text in the message display area 4I, and step III displays the item with the modification point displayed in text) If the operator determines that the item displayed in text, for example, the first item, is acceptable, then in step 112, a signal is sent to select the intention indicating term 27 of "OK" by operating a key. is input, and the process proceeds to step 113 according to the signal corresponding to "OK", and if the judgment is negative, a signal to select the intention expression term 27 "NG" is input at step 116, and the signal corresponding to this "NG" is input. Therefore, the process proceeds to step +17.In other words, in step 113, a partial regression coefficient (0, 46) having a large value among the partial regression coefficients other than those selected in step 103 is selected from among the first items displayed in text. The vehicle design elements 22 of the category corresponding to this selected partial regression coefficient are extracted from the knowledge database 2, and become the vehicle design elements 22 marked with "△" in the lower column of Table 3.

Then, this modified vehicle design element 22 is Step 1
In step 14, the second-rank display image is displayed on the display means 4 in place of the first-rank display image, and in step 115, an inquiry is made as to whether or not the corrected second-rank display image is satisfactory.

Then, the operator visually checks the second-ranked display image (7). If this is also not satisfactory, the operator returns to step 109 and re-enters the modified evaluation term 25 "unsatisfactory" using the key operation of the evaluation term input means 1. Similarly, steps 109-
115 is re-executed, and the partial regression coefficient (-
0, 15) is selected, and the vehicle design element 22 of the category corresponding to this selected partial regression coefficient is extracted from the knowledge database 2, and becomes the vehicle design element 22 marked with "mouth" in the lower column of Table 3. Each time the corrected evaluation term 25 of "unsatisfactory" is input, the display image on the display means 4 is displayed as the third place display image instead of the second place display image on the display means 4. The first item displayed in text is sequentially switched to the previously unselected item with the smaller partial regression coefficient. If the modified evaluation term 25 of "unsatisfactory" is input after the vehicle design element 22 including the one with the smallest partial regression coefficient among the first items is displayed, it has the first partial regression coefficient. Return to the display image of vehicle design requirements 122.

On the other hand, in step 117, the first item displayed in text in step IfO is an indication of the operator's intention that the first item displayed in text does not match the correction point specified in step 109. Another item included in the modified area, for example, the second item, is extracted from the knowledge database 2 and displayed in text in the message display area 41 in place of the first item displayed in text, and the process returns to step 111.

Note that the present invention is not limited to the above-mentioned embodiments, and although not shown in the drawings, for example, a combination of interior parts including a TV with built-in stereo operation unit 1, an air conditioner outlet, an operation unit, etc. Vehicle interior design or wheels.

Wheel covers, front, rear and side spoilers
It goes without saying that the vehicle exterior design, which is a combination of exterior parts including fog lamps, drive lamps, special lamps, etc., can also be displayed as an image and used to enhance the image of the vehicle.

Furthermore, by changing the design elements 22 and evaluation terms 20 stored in the knowledge database 2, it can be applied as a design device that can be used in fields other than vehicles, such as a housing design device or a machine design device.

Furthermore, the number of items and the number of categories for each item are not limited to those in the above embodiment.

Furthermore, when specifying a correction location, it is also possible to specify the entire display image. In this case, all items in the knowledge database 2, that is, the first to fifth items in the above embodiment, are displayed in text in the message display area 41, and the operator selects one of the plurality of items displayed in text. I'll do what I do.

Effects of the Margin Invention As described above, according to the present invention, when the design element displayed on the display means does not match the image of the input evaluation term, the design correction means infers another design element for the modified location from the knowledge database.

Since the design element can be extracted and changed only at the specified part by the display means, a satisfactory design can be quickly displayed as an image even if the meaning of an adjective as an input evaluation term changes over time.
