Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual alignment and securing of connectors is used, then connection reliability is achieved, but connection time and labor effort increase significantly
Solution Approach 1:
The rotating arm mechanism enables automatic alignment and securing of connectors through self-service action. When the rotating arm rotates, it automatically guides the connectors into proper alignment and secures them through the buckle mechanism, eliminating the need for manual alignment operations while ensuring reliable connection.
Solution Approach 2:
The buckle mechanism is pre-configured in the rotating arm to perform preliminary securing action. As the rotating arm approaches the connector, the buckle is already positioned to engage, performing the securing action in advance and reducing the overall connection time while maintaining connection reliability.
2Reliability
If manual alignment and securing of connectors is used, then connection reliability is achieved, but labor effort increases significantly
Solution Approach 1:
The rotating arm mechanism performs the alignment and securing operations automatically without requiring manual intervention. The mechanism self-adjusts to align connectors and the buckle automatically secures them, dramatically reducing labor effort while maintaining connection reliability through the mechanical design.
Solution Approach 2:
The rotating arm acts as an intermediary mechanism between the operator and the connectors. Instead of manually aligning and securing connectors, the operator simply activates the rotating arm, which then mediates the complex alignment and securing operations, reducing labor effort while ensuring reliable connections.
3Productivity
If rotating arm mechanism with elastic member is used, then connection speed increases, but device complexity increases
Solution Approach 1:
The elastic member changes its physical state (compressed/released) to drive the rotating arm's motion. This parameter change from elastic potential energy to kinetic energy enables automatic rotation and connector alignment, increasing connection speed while using a simple elastic component rather than complex motorized systems.
Solution Approach 2:
The elastic member replaces complex motorized or automated mechanical systems with a simple elastic-driven mechanism. This substitution achieves automatic rotating arm operation and connector alignment without requiring motors, sensors, or complex control systems, thereby increasing connection speed while minimizing device complexity.

AI summary
An electronic device includes a first and second printed boards, a bottom plate fixed to first printed board, first and second rotating arms, and an electronic member. The first rotating arm has first and second ends and the second rotating arm includes third and fourth ends. The first and third ends are rotatably fixed to the bottom plate. The fourth end defines a sliding groove into which the second end is slidably fixed. When the second end rotates around the first end toward the bottom plate, the second end slides along the sliding groove and the third end rotates toward the bottom plate. An elastic member is between the first rotating arm and the bottom plate and when the first rotating arm rotates, the elastic member abuts against the bottom plate to drive the first printed board to move toward the second printed board.
