Abstract

The invention provides an FBAS function model for product conceptual design and a product conceptual design method based on the function model and gene expression, and aims at solving the problems of low structure scheme feasibility, long design period and high cost caused by fuzzy and incomplete design information in traditional conceptual design. The method comprises the following steps: analyzing forward product design process from top to bottom to build a function expansion model on the basis of function, behavior, attribute and structure; then performing analog on biological genes, and proposing a concept, a model and a coding method of a product gene; and then performing the product conceptual design through operations such as product gene crossing, combining, transcription and translation. According to the method, the key information in the conceptual design is defined through the product genes; the genes are crossed and combined to obtain more gene forms corresponding to various function units; the genes are subjected to transcription and translation, thus more design scheme feasible solutions can be obtained, and more selection space is provided to the product creation design, and as a result, the product innovation can be effectively improved.

Description

technical field

[0001] The invention relates to a product concept design-oriented functional model and a product concept design method, in particular to a product concept design-oriented FBAS function model and a product concept design method based on FBAS and gene expression, belonging to the field of mechanical product design. Background technique

[0002] In today's economic globalization, the focus of competition among countries is technological competitiveness, which ultimately depends on the level of independent product design and development capabilities of enterprises. Therefore, in order to realize the transition from a big economic country to a powerful economy, the key lies in improving the ability of our country's enterprises to design and develop their own products, so that enterprises can have stronger market competitiveness. Currently in the era of customer-oriented knowledge economy, multi-variety, variable batch, and flexibility are the main characteristics ...

Examples

Embodiment 1

[0039] This embodiment provides an FBAS functional model oriented to product concept design. Product concept design is a process of finally generating a product structure scheme through demand function analysis, and is essentially a process of function realization and expression. The classic FBS function model is a known target function (referred to as F), according to the mapping relationship between function and behavior (referred to as B), the product behavior to achieve the target function is obtained, and then according to the mapping between behavior and structure (referred to as S) The relationship deduces the structural scheme of the product, thereby completing the expression of the function.

[0040]However, when consumers buy a product, they not only look at the function of the product, but also require the product to have excellent attributes. A change in the attributes of a product also means a change in the essence of the product. Functions and attributes are inse...

Embodiment 2

[0050] This embodiment provides a product concept design method based on FBAS functional model and gene expression, such as figure 2 As shown, by analogy to the structure of biological genes, the function F in the FBAS functional model is compared to biological traits, and the structure S is compared to biological proteins, then the product gene can be defined as a standardized gene that can be inherited by offspring during the expression process for a specific function. A collection of behavior B and attribute A. Therefore, in this method, behavior B and attribute A are defined as bases, and the ontology mapping relationship between behavior B and attribute A is defined as a hydrogen bond, then the carrier DNA of the product gene can be expressed as using behavior B and attribute A as bases , taking the ontology mapping relationship between the two as the double-strand structure of hydrogen bonds.

[0051] Since the product concept design is the process of finally generatin...
