Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional terminal blocks are used, then wire connection is achieved, but the device size becomes large and unsuitable for small spaces
Solution Approach 1:
The terminal block is divided into modular components including housing, conductive components, and clamping components that can be assembled together. This segmentation allows for compact design while maintaining full functionality for wire connection.
Solution Approach 2:
The conductive components and clamping components are nested within the housing structure, with the clamping portion integrated into the conductive component. This nesting achieves space optimization while preserving wire connection capability.
2Ease of operation
If screw terminals are used in small spaces, then wire fixation is achieved, but the operation becomes troublesome
Solution Approach 1:
The clamping component features a movable clamping portion that can dynamically adjust to grip the wire. The free end of the clamping portion moves to engage or disengage from the wire, enabling simple push-to-connect operation without screws.
Solution Approach 2:
The clamping component automatically grips the wire when inserted into the triangular structure, providing self-fixing functionality. The movable clamping portion self-adjusts to secure the wire without requiring additional fastening operations.
3Adaptability or versatility
If internal conductors are used in plug-in terminal blocks, then wire connection is enabled, but the conductors deform when wires are frequently plugged in and unplugged
Solution Approach 1:
The clamping component is designed with a movable clamping portion that dynamically responds to wire insertion and removal. The free end moves to accommodate frequent plugging operations while the triangular structure provides stable support, preventing conductor deformation.
Solution Approach 2:
The triangular structure formed by the first support portion, first connecting portion, and second clamping portion provides preemptive structural reinforcement. This pre-designed stable geometry cushions against deformation stresses from frequent wire plugging and unplugging operations.
4Ease of manufacture
If the clamping component structure is simplified, then manufacturing is easier, but the service life of the plug-in terminal block decreases
Solution Approach 1:
The clamping component is segmented into distinct functional portions: second support portion, second clamping portion, and third clamping portion. This segmentation simplifies manufacturing of each part while the assembled structure provides long-lasting durability through the triangular configuration.
Solution Approach 2:
The triangular structure provides preemptive reinforcement to the clamping component assembly. This pre-engineered stable geometry compensates for potential weaknesses in simplified manufacturing, ensuring long service life by distributing mechanical stresses throughout the triangular framework.

AI summary
A plug-in terminal block includes at least one conductive assembly including a conductive component connected with a housing assembly and a clamping component arranged on the conductive component. The conductive component includes a first support portion, a first clamping portion, a first connecting portion connected with the first clamping portion, and welding feet. The first connecting portion and the welding feet separately extend along different directions from the first support portion. The clamping component includes a second support portion and a second clamping portion. The second support portion is arranged on the first support portion. The second clamping portion is arranged above the second support portion. The first support portion, the first connecting portion, and the second clamping portion form a triangular structure. One end of the second clamping portion away from the second support portion is a free end that is movable up and down.
