Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shield is disposed inside the camera case to improve noise resistance characteristics, then noise resistance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The shield is integrated with the camera case as a unified structure rather than being a separate component. The shield parts are formed as continuous extensions from the camera case body, eliminating the need for separate shield components and reducing assembly steps while maintaining noise shielding effectiveness.
Solution Approach 2:
The camera case serves dual functions: it provides structural housing for the imaging components and simultaneously acts as a noise shield through its integrated shield parts. This multi-functionality reduces the total number of components needed while achieving both mechanical support and electromagnetic noise protection.
2Reliability
If complex shield configurations are used to improve noise resistance, then noise resistance is improved, but ease of manufacture deteriorates
Solution Approach 1:
The shield structure is merged with the camera case as a single molded part, allowing both to be manufactured together in one process. This integration eliminates the need for separate shield manufacturing and assembly operations, significantly improving ease of manufacture while maintaining effective noise shielding coverage.
