Conceptual Design of Bubble Film Unit

With the continuous progress of science and technology, the market situation of manufacturing industry is changing rapidly, and the competition of modern manufacturing industry is becoming more and more fierce. The traditional mechanical design methods can not meet the design requirements of modern manufacturing industry gradually. Whether the mechanical design process can be more efficient and innovative has become one of the strategic factors for enterprises to adapt to market competition. Conceptual design is not only the beginning stage of design, but also the most concentrated and prominent stage of innovative performance, which has a decisive impact on the performance and market competitiveness of new products. Therefore, it is necessary to study the related theories and methods of product conceptual design process.

Bubble film unit is the basic equipment of packaging material manufacturing enterprises. It realizes the state change in the production process through a series of process links. Due to the lack of a unified bubble film industry standard, resulting in a variety of units in the industry. In the conceptual design process of large and complex machinery such as bubble membrane unit, a large number of conceptual information is waiting to be processed. In order to clearly express the structure and mapping relationship of conceptual information at different levels, it is necessary to study the model of conceptual design. In reasoning conceptual scheme, the mode of knowledge application and the choice of knowledge directly determine the effect of reasoning and the efficiency of reasoning. Therefore, the study of reasoning mechanism is particularly important. Considering the uncertainty of information in the conceptual design stage of bubble membrane units, it is very difficult to evaluate and optimize candidate conceptual schemes. Therefore, it is necessary to study the evaluation and optimization problems in the conceptual design process.
