Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening members (bolts, screws) are used to secure the lid part to the case body part, then the waterproof performance and structural strength are improved, but the assembly cost and device complexity increase
Solution Approach 1:
The patent combines the sealing function and the fastening function into a single integrated structure. The seal material is designed with engagement convex parts that directly engage with acceptance parts on the case body, eliminating the need for separate fastening members. This merging of functions reduces assembly complexity while maintaining waterproof performance through the continuous seal material structure.
Solution Approach 2:
The patent extracts the fastening function from the sealing structure by designing the seal material itself to have engagement capabilities. The convex parts protruding from the seal material serve as the fastening mechanism, separating the fastening role from traditional bolts or screws while maintaining the sealing integrity through the same material component.
2Reliability
If conventional seal materials (rubber gaskets, liquid gaskets) are used, then the waterproof sealing is achieved, but the heat resistance and ease of reassembly deteriorate
Solution Approach 1:
The patent employs a composite seal material comprising a base material (such as rubber or silicone) combined with heat-resistant additives or coatings. This composite structure maintains the elastic sealing properties of the base material while the heat-resistant components enable the seal to withstand high temperatures in automobile engine compartments without degrading or losing its sealing capability.
3Ease of operation
If adhesive silicone gel is used as seal material, then the ease of reassembly is improved, but the heat resistance and sealing reliability may worsen
Solution Approach 1:
The adhesive silicone gel is formulated as a composite material with enhanced heat resistance properties. The gel maintains its adhesive characteristics for easy reassembly while incorporating heat-stabilizing components that prevent degradation at high temperatures, thus preserving sealing reliability in demanding automobile engine environments.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the silicone gel to achieve optimal balance between adhesiveness and heat resistance. By adjusting cross-linking density, filler content, and molecular structure, the seal material achieves sufficient adhesion for easy reassembly while maintaining structural integrity and sealing reliability under high temperature conditions.
