Concept design of bubble film machine (air cushion film machine)

The bubble film machine (air cushion film machine) concept design is an early stage in the design of mechanical products, the core of which is a series of orderly, organizeable and targeted design activities from analyzing user needs to generating concept products. Aiming at the complex problem of conceptual design of bubble film unit, the multi-color set theory is used to hierarchically model the concept knowledge of the unit through the function-constrained-structure model. Each layer includes the unit market demand, program description and market demand. To the reasoning matrix described in the scheme and its constraints, where the market demand is input to the layer, corresponding to the uniform color of the multi-color set scheme layer, the scheme description is the layer output, corresponding to the individual color of the multi-color set, and the reasoning matrix is the individual color and The color matrix is unified, and finally the fuzzy evaluation method is used to find out the product optimization combination design.
