Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive line of flexible substrate is used to transmit static electricity to ground, then static electricity can be discharged, but the lens apparatus becomes larger and assembly performance lowers due to complicated routing
Solution Approach 1:
The patent combines the conductive pattern directly with the fixed member structure, merging the static electricity discharge function into the existing structural component. This eliminates the need for separate flexible substrate routing and conductive lines, thereby reducing device complexity while maintaining static electricity discharge capability.
Solution Approach 2:
The fixed member serves multiple functions: it provides structural support and simultaneously acts as a conductive path for static electricity discharge through the integrated conductive pattern. This multi-functionality reduces the number of components needed and simplifies the overall structure.
2Reliability
If a conductive elastic member is disposed between operation ring and mount, then static electricity can be transmitted, but the lens apparatus becomes larger and strength lowers
Solution Approach 1:
The conductive pattern is integrated directly into the fixed member, eliminating the need for separate elastic members. This merging approach maintains structural strength while providing the necessary conductive path for static electricity discharge.
Solution Approach 2:
Instead of using a separate elastic member that copies the conductive function, the patent creates the conductive path directly on the fixed member surface through conductive patterns, achieving the same electrical function with a more integrated and structurally sound solution.
