Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If board-to-board connectors are fixedly soldered on circuit boards, then structural stability is improved, but reliability deteriorates due to detachment and signal loss under wobbling conditions
Solution Approach 1:
The patent implements a floating base structure that allows dynamic movement along multiple axes (X-axis, Y-axis, and Z-axis) to adapt to external forces and wobbling conditions, transforming the rigid fixed connection into a dynamic adaptive connection that maintains reliability under varying conditions
2Manufacturing precision
If connectors are made fixed and rigid, then manufacturing precision is improved, but adaptability deteriorates in environments with movement and vibration
Solution Approach 1:
The floating base is designed with multi-axis movement capability that allows the connector to dynamically adjust its position while maintaining precise electrical contact, enabling the system to adapt to environmental vibrations and movements while preserving connection accuracy
Solution Approach 2:
The patent utilizes elastic elements and flexible contact portions that can change their physical parameters (elastic deformation, flexibility) to absorb external forces and maintain stable electrical connection under varying operational conditions
3Reliability
If connectors are designed to be movable to absorb external forces, then reliability is improved, but device complexity increases
Solution Approach 1:
The connector is divided into distinct functional modules: a fixed base for mounting, a floating base for movement, and flexible contact portions for electrical connection. This segmentation allows each component to perform its specific function while keeping the overall structure manageable and manufacturable
Solution Approach 2:
The patent employs flexible contact portions and elastic elements that provide the necessary movement and force absorption capabilities through material flexibility rather than complex mechanical mechanisms, simplifying the overall device structure while maintaining reliability
