Embodiment

[0085] Embodiment: This embodiment is based on figure 1 The design flow chart shown in the figure takes hydraulic jack design as an example to map user requirements to product structure.

[0086] (1) Demand classification and screening method

[0087] For user requirements {CR i}={operating force, lifting weight, lifting stroke, lifting height, lifting stability, vehicle tools, lighting, weight, service, price}, set two opposite questions for each requirement, such as "when the product operates What do you think about the effort? What do you think when the product operation is labor-saving?" Filling out the user survey form.

[0088] Query the two-dimensional evaluation table, evaluate each requirement, obtain the type of each requirement and give the corresponding weight, take A=3; O=1; M=5; I=0; R=-3; Q= 0.

[0089]

[0090] When multiple users participate in the survey, count the number of valid questionnaires and the number of choices of various types of requirement...

Abstract

The invention discloses a product requirement-structure mapping method based on an effect. According to the method, it is thought that all stages of concept design must be comprehensively considered, and an efficient and consistent design process is provided for concept design of a product. Thus, the product requirement-structure mapping method based on the effect is put forward. Common steps mainly include the steps that requirements are analyzed, the requirements are converted into functions, and the functions are mapped into structures. By means of the method, design efficiency can be improved, and design cost is reduced.

Description

technical field [0001] The invention belongs to the field of conceptual design of mechanical product design, and in particular relates to an effect-based product requirement-to-structure mapping method. Background technique [0002] In the entire design and manufacturing process of a product, although conceptual design only accounts for 5% of the development cost, it often determines 70% to 80% of the total cost and directly affects the quality, cost and performance of the product. Therefore, it is necessary to develop efficient product concept design methods to reduce design costs and ensure design quality. The mapping of product requirements to structure is an important content and key process of product conceptual design, which is mainly embodied by effect-based requirements acquisition, processing, transformation technology, and function-to-structure mapping algorithm. The purpose is to quickly establish a set of conceptual structures through the mapping method. Existin...
