Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical wires are used to connect the voltage application unit and the lens optical system through a feed-through connector, then electrical connection is established, but the attachment and detachment operations become cumbersome and complex
Solution Approach 1:
The patent merges the electrical connection function with the mechanical connection function by integrating terminals directly into the feed-through connector structure. The connection pieces with bias portions make direct contact with these terminals, eliminating the need for separate electrical wires. This integration simplifies the attachment and detachment operations while maintaining reliable electrical connection between the voltage application unit and the lens optical system.
2Power
If electrical wires are attached to connect the voltage application unit and the lens optical system, then voltage can be applied to the lens optical system, but the overall device complexity increases
Solution Approach 1:
The patent extracts and eliminates the unnecessary electrical wires from the system by implementing direct contact terminals on the connection pieces. The bias portions on the connection pieces directly contact the terminals of the feed-through connector, providing both mechanical support and electrical connection functions simultaneously. This extraction of redundant components reduces device complexity while preserving the voltage application capability to the lens optical system.
