Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different parts are individually formed and then assembled, then manufacturing flexibility is improved, but manufacturing complexity and assembly process errors increase
Solution Approach 1:
The patent merges the housing and wire layer into a single integrated component formed by injection molding. The wire layer is embedded within the housing structure, eliminating the need for separate assembly operations. This integration reduces manufacturing complexity while maintaining the ability to produce customized camera modules.
2Adaptability or versatility
If different parts are individually formed and then assembled, then design adaptability is improved, but assembly process errors and quality deterioration occur
Solution Approach 1:
By combining the housing and wire layer into a single molded part, the patent eliminates assembly interfaces where errors could occur. The integrated structure ensures consistent positioning and connection reliability while maintaining design adaptability through the injection molding process.
Solution Approach 2:
The wire layer is pre-positioned and embedded within the housing structure during the injection molding process. This preliminary integration ensures precise positioning and eliminates subsequent assembly operations that could introduce errors or compromise quality.
3Adaptability or versatility
If multiple components are assembled together, then functional versatility is improved, but manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by merging the housing and wire layer into a single injection-molded component. This eliminates the need for separate manufacturing and assembly operations, reducing labor and process costs while maintaining functional versatility through the integrated design.
