Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional materials are used for liquid cooling plates, then material selection and forming processes are limited, but mechanical strength and deformation resistance are insufficient
Solution Approach 1:
The patent uses polyphenylene sulfide resin as a composite material that combines high mechanical strength, deformation resistance, and extrusion processability. This single material solution resolves the contradiction by providing both the required strength properties and ease of manufacturing through extrusion molding.
2Productivity
If conventional materials are used for extrusion molding, then processing is simpler, but material breakage and poor extrusion flow occur
Solution Approach 1:
The patent optimizes the molecular weight parameters of the polyphenylene sulfide resin to achieve the balance between extrusion flow and material integrity. By controlling the molecular weight within a specific range, the material exhibits both good extrusion flow characteristics and resistance to breakage during processing.
3Strength
If material properties are enhanced for better mechanical strength, then deformation resistance improves, but extrusion flow and processing become difficult
Solution Approach 1:
The patent carefully selects and controls the molecular weight parameter of the polyphenylene sulfide resin. By optimizing this parameter, the material achieves high deformation resistance while maintaining good extrusion flow properties, resolving the contradiction between mechanical strength and ease of manufacturing.
