Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If leather belts are used for friction-based transport of preforms, then accumulation and transport efficiency are improved, but wear resistance deteriorates rapidly
Solution Approach 1:
The patent changes the material parameter of the belt from leather to a composite structure with synthetic fibers (polyester, polyamide, acrylic) and rubber coating. This material substitution maintains the friction coefficient needed for preform transport while significantly improving wear resistance and durability under thermal conditions.
Solution Approach 2:
The belt employs a composite construction combining synthetic fibers for structural integrity, rubber coating for friction and flexibility, and fabric reinforcement. This composite material approach resolves the contradiction by providing both the necessary friction for transport efficiency and enhanced durability for wear resistance.
2Ease of operation
If leather belts are used for friction-based transport, then transport function is maintained, but dust pollution increases
Solution Approach 1:
The patent replaces the natural leather material with synthetic materials that do not generate dust particles. The synthetic fiber and rubber composite belt maintains the friction-based transport function while eliminating the dust pollution problem inherent in natural leather, creating a cleaner operating environment.
3Force
If natural leather material is used, then friction-based transport is achieved, but resistance to heating deteriorates
Solution Approach 1:
The patent changes the thermal parameter of the belt material from natural leather to heat-resistant synthetic materials. The rubber coating and synthetic fibers can withstand higher temperatures without degrading, maintaining friction force while providing superior resistance to heating in the preform transport environment.
