Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are connected to different terminal blocks within different wiring pieces, then electrical connections can be established, but wire cross-stacking occurs leading to wire skin damage and short circuits
Solution Approach 1:
The isolation piece divides the wiring piece into multiple isolated compartments, separating wires connected to different terminal blocks. This segmentation prevents wire cross-stacking while maintaining ease of connection, as each wire has its own dedicated space within the structured compartments.
Solution Approach 2:
The isolation piece acts as an intermediary structure between terminal blocks and wires. It provides a mediating mechanism that organizes and separates wires physically, preventing direct contact between wires that would otherwise cross-stack and cause short circuits.
2Adaptability or versatility
If terminal blocks are arranged in different wiring pieces, then electrical connections can be made, but structural limitations cause wire cross-stacking and short circuits
Solution Approach 1:
The isolation piece creates segmented compartments within the wiring piece, allowing terminal blocks to be arranged in different locations while maintaining physical separation between their associated wires. This enables versatile terminal block placement without compromising connection safety.
Solution Approach 2:
The isolation piece introduces a spatial dimension solution by creating three-dimensional compartmentalization within the wiring piece. This allows terminal blocks to be arranged in different spatial positions while the isolation structure manages wire routing to prevent cross-stacking.
3Ease of operation
If isolation piece is detachably connected to clamping piece, then installation and removal are convenient, but connection stability must be maintained
Solution Approach 1:
The buckling assembly provides a dynamic connection mechanism that allows the isolation piece to be easily installed and removed while maintaining stable connection during operation. The elastic deformation capability enables convenient assembly/disassembly, while the locked position ensures stability during use.
Solution Approach 2:
The elastic arm changes its physical state between deformed (during installation) and restored (during stable connection). This parameter change allows the connection to transition from an installation state to a stable operational state, providing both ease of installation and connection stability.

Function Achieved in This Case
The isolation structure enhances connection stability and safety by preventing wire cross-stacking, ensuring secure electrical connections and improved safety in electrical devices.
Implementation Method 1
the elastic arm is fixed to the isolation piece; the hook portion is abutted against an edge of the limiting cavity, so that the convex bar cannot detach from the limiting cavity
