Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid pin connector is used to ensure stable electrical connection, then connection reliability is improved, but insertion difficulty increases due to friction and pin bending when misaligned
Solution Approach 1:
The connector employs a dynamic alignment mechanism where the plug can move laterally within a gap relative to the socket. This dynamic adjustment allows the connector to self-align during insertion, reducing friction and preventing pin bending while maintaining stable electrical connection. The movable connection body transitions from a static rigid structure to a dynamic system that adapts to alignment variations.
2Productivity
If multiple pins are inserted into sockets simultaneously, then electrical connection efficiency is improved, but misalignment problems worsen causing increased friction and potential pin damage
Solution Approach 1:
The connector design enables self-alignment through the gap mechanism, where the plug automatically adjusts its position relative to the socket during insertion. This self-service alignment eliminates the need for precise manual alignment, allowing multiple pins to be connected simultaneously without misalignment damage while maintaining high connection efficiency.
3Ease of manufacture
If a fixed structure is used for the connector, then manufacturing simplicity is improved, but adaptability worsens when alignment variations occur
Solution Approach 1:
The connector incorporates a movable connection body that can laterally shift within a defined gap, providing adaptability to alignment variations. This dynamic feature is achieved through simple structural modifications rather than complex mechanisms, maintaining manufacturing simplicity while significantly improving alignment adaptability.

AI summary
A medical device self-aligning connector is disposed on a medical device cover, and has a moving connection body, passing through a hole formed in the medical device cover, and having multiple connection elements that electrically connect to a target component. The connector further has a base that supports the moving connection body, and an elastic body that press-connects the moving connection body to the medical device cover. The moving connection body is designed to cause a certain gap to exist between the moving connection body and the hole, and moves within the range of the gap.
