Embodiment 1

[0039] Referring to Fig. 1, a product concept design method based on the matter-element of extension information, the method mainly includes the following steps: (1), express the user's product design requirements in the form of matter-element of extension information, and establish the matter-element model R =(N, c, v), the matter-element model includes three basic attributes that constitute the product: object name N, feature c and value v;

[0040] (2), set up the product rule base, described product rule base comprises the matter-element relationship between the extension information matter-elements, the corresponding rule explanation to the matter-element relationship;

[0041] (3) Use drawing tools to develop on the drawing software platform, and establish a product example library;

[0042] (4) Link the extension information matter element directly with the instance library to form a network structure:

[0043] M = [R, L, σ, ρ, P],

[0044] Among them, R is the set of...

Embodiment 2

[0063] Referring to Fig. 1, Fig. 2, Fig. 3, and Fig. 4, a design method of a reducer based on extension information matter-element includes the following steps:

[0064] The first step is to investigate the needs of users through discussions, questionnaires, etc., mainly in terms of the performance and price of the reducer.

[0065] The second step is to express the user's demand information with the extension information matter-element model. The matter-element model covers three basic attributes of things: object name, characteristic and value, and its representation form is as follows: According to the definition of information matter-element, use an entity together with all attributes and attribute values ​​to form a full-character object-element with four connections of instance, generalization, aggregation and attribute, such as: R 1 =(transmission unit type gear), R 2 =(transmission unit type connection), R 11 =(gear transmission type cylinder transmission), see Fig....

Embodiment 3

[0129] With reference to Fig. 1, Fig. 5, a kind of tool magazine concept design method based on extension information matter element, the product rule base of the present embodiment includes:

[0130] Matter-element relationship 1: vertical processing -> matter-element of turret tool magazine -> above the machine tool;

[0131] Explanation of the corresponding rules: the turret tool magazine is installed on the vertical processing machine tool;

[0132] Matter-element relationship 2: Horizontal processing -> matter-element of disk tool magazine -> top of the machine tool;

[0133] Explanation of the corresponding rules: the disc tool magazine is installed on the horizontal processing machine tool;

[0134] Matter-element relationship 3: horizontal processing -> chain tool magazine matter-element -> floor type;

[0135] Explanation of the corresponding rules: the chain tool magazine is installed on the ground of the horizontal processing machine tool;

[0136] Matter-element...

Abstract

The invention discloses a production concept design method based on extendable information element in the production concept design domain, which comprises the following steps: displaying the user design demand at information element pattern; inputting certain information element directly for user or extracting from the information database; satisfying the cognition thinking; establishing the limit regular base and example base among the extendable elements; extracting the limits automatically in the regular base by system; activating the relative element automatically; modifying the program in the extendable example base to form the satisfied design program. The invention displays good flexibility, rational mapping method, strong evolution ability and high inference efficiency.

Description

(1) Technical field [0001] The invention relates to a conceptual design method of a product, in particular to a conceptual design method of a product based on an extension information matter element. (2) Background technology [0002] As a key link in modern industrial production, product design occupies an extremely important position in the entire life cycle of a product. It fundamentally determines the intrinsic nature of a product, as well as its quality and cost. 70% of product cost is determined by the design stage. As an innovative activity, design will develop along with the development of human beings. It has been approved by more and more designers, and it has been demonstrated from a theoretical level. In the last forty or fifty years, a number of various Unique new design method. [0003] With the deepening of people's understanding of the essence of product design, in the late 1990s, with the improvement of realistic display, multimedia, virtual reality and CA...
