Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional materials are used for liquid cooling plates, then material selection and forming processes are complex, but mechanical properties and extrusion flow are poor
Solution Approach 1:
The patent uses a composite material system consisting of polyphenylene sulfide resin as the base material and elastomeric modifier as the toughening agent. This composite structure combines the high strength and rigidity of PPS with the flexibility and impact resistance of the elastomeric phase, achieving both excellent mechanical properties and ease of extrusion molding. The composite material resolves the contradiction by integrating two materials with complementary properties into a unified system that simultaneously satisfies strength requirements and processing ease.
2Temperature
If polyphenylene sulfide resin is used, then rigidity and heat resistance are improved, but toughness and extrusion flow are reduced
Solution Approach 1:
The patent applies parameter changes by modifying the molecular structure and composition of the polyphenylene sulfide resin system. Specifically, it introduces an elastomeric modifier with specific molecular weight and composition parameters to change the overall material properties. This parameter modification allows the material to maintain the heat resistance of PPS while improving toughness and extrusion flow characteristics, resolving the contradiction between heat resistance and toughness.
Solution Approach 2:
The patent creates a composite material system where polyphenylene sulfide resin provides heat resistance and rigidity, while the elastomeric modifier contributes toughness and flexibility. The synergistic interaction between these two components resolves the contradiction by allowing each material to contribute its advantageous properties to the final composite, achieving both heat resistance and improved toughness simultaneously.
3Productivity
If extrusion molding is used for harmonica tube, then production efficiency is improved, but material breakage and poor extrusion flow occur
Solution Approach 1:
The patent modifies the material parameters by incorporating an elastomeric modifier with specific molecular weight, composition, and flexibility characteristics. This parameter change improves the extrusion flow properties of the polyphenylene sulfide resin, allowing smooth flow through the extrusion die without breakage. The modified material maintains high production efficiency while eliminating material breakage issues, resolving the contradiction between productivity and reliability.
