Intelligent Design of Product Forms Based on Design Cognitive Dynamics and a Cobweb Structure

Abstract

Design is a complex, iterative, and innovative process. By traditional methods, it is difficult for designers to have an integral priori design experience to fully explore a wide range of design solutions. Therefore, refined intelligent design has become an important trend in design research. More powerful design thinking is needed in intelligent design process. Combining cognitive dynamics and a cobweb structure, an intelligent design method is proposed to formalize the innovative design process. The excavation of the dynamic mechanism of the product evolution process during product development is necessary to predict next-generation multi-image product forms from a larger design space. First, different design thinking stimulates the information source and is obtained by analyzing the designers’ thinking process when designing and mining the dynamic mechanism behind it. Based on the nonlinear cognitive cobweb process proposed by Francisco and a natural cobweb structure, the product image cognitive cobweb model (PICCM) is constructed. Then, natural cobweb predation behavior is simulated using a stimulus information source to impact the PICCM. This process uses genetic algorithms to obtain numerous offspring forms, and the PICCM’s mechanical properties are the energy loss parameters in the impact information. Furthermore, feasible solutions are selected from intelligent design sketches by the product artificial form evaluation system based on designers’ cognition, and a new product image cognitive cobweb system is reconstructed. Finally, a case study demonstrates the efficiency and feasibility of the proposed approach.

Optimal Design of Product Form for Aesthetics and Ergonomics

“…Kang et al constructed a multi-objective optimization mathematical model for the interface element layout based on four indicators of hierarchy, relevance, simplicity and comfort, and used the genetic algorithm to realize the optimal design of product interface layout [9]. Yang et al constructed a product form evaluation system based on the designer's cognition based on the nonlinear cognitive spider web model proposed by Francisco, and completed the innovative design of the product form by genetic algorithm [29]. Lugo et al took the contour of a perfume bottle as an example, described it using the Bezier curve, constructed three aesthetic metrics (symmetry, parallelism, and continuity) based on the Gestalt rule, and combined it with a gradient-based optimization algorithm to achieve an optimal design of the perfume bottle form [19].…”

From Science Fiction to Science Facts

“…Artificial intelligence scores are relatively high [21]. In other fields, such as product design, artificial intelligence is also beneficial in finding new forms through the parameters set [22].…”

“…Natural cultural differences may partially compensate for a lack of inventiveness and regional growth in China's artistic and creative sectors [9,10].Cultural heritage encompasses the mental and bodily contributions of the local population to the long-term social and historical growth of an entire nation or region [11]. It is constantly enhanced established and enhanced [12]. Regional social, economic, and cultural developments are correlated with one other, according to scientific as well as technical advancements, basic beliefs [13].…”
