1. Field of the Invention
The present invention relates to the design of manufactured products, etc. using Computer Aided Design (CAD) or Digital Mock-Up (DMU) and Computer Aided Manufacturing (CAM).
2. Description of the Related Art
In recent years, in the manufacture and development of a variety of products, manufacturing and development approaches that take into account the global environment are being pursued.
In order to perform manufacturing and development that take into account the recycling of natural resources, such as dismantlability, for example, it is necessary to perform simulation design on a computer. In particular the simulation is performed to simulate the materials used in the components that configure the product, the arrangement locations, etc. in addition, it is necessary to perform optical product assembly. The document discussed below relates to design methods that take into account recyclability to assist product development.
Japanese Unexamined Patent Application Publication 2003-271677 discloses a method that can be used when product design is performed as a means of visually discriminating from the display status the type of attribute being assigned to a component. In a case in which information to which a variety of attributes such as material belong, shape information that represents the shape of that component are displayed using CAD or the like on a display apparatus of an information processing apparatus. Display statuses such as the color that conform to an attribute value are assigned for one attribute, and the display is switched to visually discriminate differences according to the attribute.
After a correspondence table has been created, it will be possible to visually ascertain the attribute value by making the component color a color (and/or luminance/transparency) of corresponds to an attribute value that the component. In this method, it is possible to manage the correspondence table for each attribute, and it is possible to make visual evaluation easy by switching the attribute for one which a user would like to perform or show component color-coding. For example, when a material is selected as the attribute, it is possible to confirm on the screen which material is used in the component.
In the same way, it is possible to visually confirm the difference in the recyclability ratios of the component for which color-coding has been performed in the recyclability ratio, and product design that takes into account dismantlability becomes easy.
Through the aforementioned method, with respect to the materials being used in the components, for example, it is possible to visually recognize on the display screen what material the component is using by managing the colors that correspond to the respective materials. The method described is effective in the work of sequentially evaluating the visual evaluations with respect to the attributes of material, recyclability ratio, and dismantlability.
However, in a case in which product dismantlability evaluation is performed as a part of the environmental evaluation of the product to be designed, for example, a need exists to determine whether the material being used in a component is a metal group or a resin group and to further know whether the adjacent component is the same material.
The above-identified type of need exists because there are differences in work in that needs to be done when breaking down components; most of the resin group cannot be recycled. So it is okay not to break it down carefully. If adjacent components are the same material, those components need not be broken down.
For example,
In actuality, the product is displayed in relation to the classification, material, etc. in a status that has been combined according to components A, B, C, etc. Product evaluation may be performed by color display in a status in which the product has been broken down by component. In addition, environmental evaluation, etc. of the product will be performed while alternately referring to the two color-coding screens of material and classification. In this method, since evaluation is performed while the screen is being switched, one must remember one of the statuses, and a problem occurs in that when the number of component points or the number of attribute values is increased, evaluation became difficult.
In addition, when dismantling the apparatus, since a determination is made as to whether further dismantling is necessary in conjunction with confirming whether or not the material is recyclable, it was also necessary to check whether or not the components being assembled were the same material. In such a case, heretofore, there were problems in that it was necessary to evaluate while switching the display status. This resulted from the attribute of recyclability and the display status resulting from the attribute of the material, was poor i.e. inefficient. Oversights also occurred.
In the present invention, the purpose is to make it possible to visually check on a display screen the correspondence relationship between the shape and two or more attributes. In the case in which shape information is associated with a plurality of attributes, a means is provided that causes two or more selected attributes to correspond to respectively independent display information, combining them, and updating the shape display information.

Finally, a representation results output portion that outputs the representation results synthesized in said representation synthesis portion is provided.
In the present invention, the attribute information is judged by assigning hue, lightness, etc. to the attribute values in the plurality of attribute information and simultaneously displaying a plurality of attribute information. It is therefore possible to eliminate the time and effort of switching the display and to make the work of product design more efficient. In addition, since it is possible to simultaneously evaluate a plurality of attribute information, it is possible to make product design easier even in cases in which decisions relating to product design are difficult based on single pieces of attribute information.
At this time, saturation is considered to be the maximum values of the respective hues. Hue is assigned to the small classification 110 in the classification table, and lightness is assigned to the material. Here, in this embodiment, it is made possible to simultaneously discriminate two types of attributes. In addition, in the case in which one of the attributes of the two types of attributes expresses a classification, hue is assigned to the attribute that is the classification, and lightness is assigned to the other attribute.
In this way, attributes that belong to the same classification are expressed by the same hue, and the individual differences within them can be discriminated by the lightness of the color. And by using hue and lightness, it is possible to simultaneously evaluate the classification and the material of the component.
Because human vision is sensitive to changes in lightness more than changes in color, in this exemplary embodiment those in which the respective attributes have a high number of attribute values or range are made to correspond to the lightness, and those which have few are made to correspond to the hue. In addition, the attribute values refer to the properties, etc. of the attribute included in the component. For example, if it is the classification, the attributes values are metal and resin. If it is the material, the attribute values are aluminum and plastic. Also, a hue of 0 degrees is red. A hue of 240 degrees is blue A hue of 120 degrees is green. A hue of 60 degrees is yellow. A hue of 300 degrees is green, and a hue of 90 degrees is yellowish green.
A lightness table 515 is assigned to the materials, and a hue table 520 is assigned to the recyclability ratios. This may also be the opposite case, and the hue table 520 may be assigned to the materials, and the lightness table 515 may be assigned to the recyclability ratios.
In addition, in the case in which one attribute of the two types of attributes represents the classification, hue is assigned to the attribute that is the classification, and transparency is assigned to the other attribute. A hue of 0 degrees is assigned to iron group metal, and a hue of 240 degrees is assigned to non-iron group metal, a transparency of 0 is assigned to the material iron, a transparency of 0.7 to steel, a transparency of 0.3 to cast iron, a transparency of 0 to copper, a transparency of 0.7 to aluminum, and a transparency of 0.3 to lead. In this way, it is possible to represent attributes belonging to the same classification using the same hue. It is also, possible to recognize individual differences among these by the transparency of the color, and it is possible to simultaneously evaluate the classification and the material.
Through this, it is possible to represent attributes belonging to the same classification using the same hue. It is also possible to recognize individual differences among these by the transparency of the color, and it is possible to simultaneously evaluate the classification and the material.
Through this, it is possible to represent attributes belonging to the same classification using the same hue, and it is possible to recognize individual differences among these by the transparency of the color. It is also possible to simultaneously evaluate the material and the recyclability ratio.
Shape information is stored in the shape information storage apparatus 2, and attribute information is stored in the attribute information storage apparatus 3. Shape information refers to information for discriminating the external appearance of a component, and attribute information refers to the material information used in the component or to the creator, creation date, and the recyclability ratio, reusability ratio, etc. of the component. Here, the recyclability ratio shows the efficiency that can be used in new product manufacturing without processing that component.
The reusability ratio shows the efficiency that can be used in new product manufacture by reprocessing the component such as by heat treatment. In addition, in this exemplary embodiment, a shape information storage apparatus 2 and an attribute information storage apparatus 3 are provided outside the information processing apparatus 1, but it is not limited to this, and shape information storage apparatus 2 and attribute information storage apparatus 3 may also be provided inside the information processing apparatus 1.
In the attribute information selection portion 11, attribute information that assigns lightness, etc. is selected from the attribute information storage apparatus 3. In the display method selection portion 12, a selection is made as to whether to use and display any of the lightness, hue, or saturation with respect to the attribute information selected in the attribute information selection portion 11. In the display information and attribute value correspondence portion 13, a correspondence is made between the selected product attribute information and the selected lightness, etc., and assignment is performed. In the shape and display information update portion 14, the attribute information display format is updated along with the output format of the display apparatus 5. Display information such as the format that displays the attribute information for displaying the component is appropriately stored in the display information storage portion 15. The shape display portion 16 displays the component shape by means of the display format updated in the shape and display information update portion 14, sends it to the display apparatus 5, and performs display output of the shape of the component by means of the display apparatus 5. Here, the representation selection portion corresponds to the display method selection portion 12 in the example of the embodiment, and the component representation portion corresponds to the shape display portion 16.

In the case in which color assignment has been performed for all components, the display apparatus is used to perform product image output in step 1511. In the case in which color assignment has not been performed for all of the components, color (HSV) information creation processing is again performed in step 1508.
Here, in the case color assignment has not been completely performed for all of the components, one may again carry this out from color assignment processing to the components in step 1509.
First, attribute 1 and attribute 2 are selection processed from the attribute information 1320 stored in the attribute information storage apparatus 3 using an input apparatus 4 in steps 1601 and 1602. Here, attributes 1 and 2 are the two attributes selected from the attributes of the components of the product, and they have had numbers added in terms of format.
