Problems solved by technology

However, the conceptual design principle sketch pays more attention to the visualization of functional principles and corresponding structural principle designs. FFDB, which is good at time series functional modeling, cannot solve the visualization problem of conceptual design well.

Embodiment Construction

[0039] The implementation of the present invention will be described in detail below with reference to the drawings and examples. The embodiments are implemented on the premise of the technical solution of the present invention, and the protection scope of the present invention is not limited to the specific forms of the following embodiments.

[0040] Such as figure 1 As shown, the present embodiment includes three major modules, namely the conceptual sketch knowledge base module, the functional sketch module and the structural sketch module. The concept sketch knowledge base module stores design experience and knowledge in a standardized data format, and its role is to provide underlying data for the functional sketch module and the structural sketch module; the functional sketch module responds to the designer's functional requirements input and accesses The underlying data of the concept sketch knowledge base module, query similar functional structural elements with simil...

Abstract

The invention discloses a design system and a design method for a concept design principle sketch based on functional flow, which comprises a function sketch and a structure sketch, wherein the function sketch is used for representing a principle scheme of a functional layer in the unit of functional structural element, each of the functional structural elements achieves specific functions through certain principles and methods, and the structure sketch is used for representing a principle scheme of a structural layer, and further determining transfer modes of functional flow among functional structural elements and expressing connecting modes among functional structural elements. The design method includes the steps of building a knowledge base module of principle sketches, drawing the function sketch by means of a function sketch module, and drawing the structure sketch by means of a structure sketch module. The design system and the design method for the concept design principle sketch based on functional flow achieve rapid building and representing of the concept design principle through a bi-dimensional vector diagram.

Description

technical field [0001] The invention relates to the fields of design, engineering, and graphics, in particular to a functional flow-based concept design principle sketch design system and design method. Background technique [0002] Conceptual design is an important part of engineering design and the main link of engineering innovation. Conceptual design requires high experience and knowledge of designers, so communication, sharing and collaboration in the conceptual design process are very important. This requires a sketch method that can express the design scheme conveniently and quickly, so as to support the visualization and collaboration of conceptual design. [0003] After searching the existing technical documents, it was found that Pahl and Beitz proposed in "Engineering Design" in 1984 to express the function of the product with the concept of input and output flow (Input / Output Flows) to carry out product concept modeling. Functional design is the main method of ...
