Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional terminal designs are used with multiple components and intricate structures, then reliable wire pressing and electrical connection are achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the shift member and the fixing structure into a single integrated component. The shift member includes an insertion section with elastic walls that directly form the fixing mechanism, eliminating the need for separate fixing components. This merging reduces the number of parts while maintaining the reliability of wire pressing through the elastic deformation of the insertion section walls.
Solution Approach 2:
The patent utilizes elastic deformation of the insertion section walls as a parameter change mechanism. When the shift member is inserted, the walls of the insertion section elastically deform to provide a clamping force that secures the terminal. This elastic parameter change enables reliable wire pressing without requiring complex mechanical fastening structures.
2Ease of manufacture
If conventional terminal structures with multiple components are used, then functional requirements are met, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The invention merges multiple functional components into a single shift member assembly. The insertion section with its elastic walls integrates the functions of insertion, fixing, and wire pressing into one component, significantly reducing the number of parts that need to be manufactured and assembled.
Solution Approach 2:
The insertion section walls provide self-service fixing through their inherent elastic properties. When inserted, the walls automatically deform and clamp onto the terminal, providing a self-fixing mechanism that eliminates the need for additional fastening components or complex assembly procedures.
3Strength
If the insertion section walls are made thick for structural strength, then mechanical strength is improved, but elastic effect and operational flexibility are reduced
Solution Approach 1:
The patent optimizes the wall thickness parameter of the insertion section to achieve the right balance between strength and elasticity. The walls are designed with controlled thickness to provide sufficient mechanical strength while maintaining the elastic deformation capability needed for flexible operation and secure clamping of the terminal.
Solution Approach 2:
The insertion section walls are designed with non-uniform thickness distribution, creating local quality variations. Certain areas have thinner walls to provide elastic flexibility for clamping, while other areas maintain sufficient thickness for structural strength. This local quality optimization resolves the contradiction between overall strength and operational flexibility.

AI summary
A shift member fixing structure of electrical connection terminal includes an assembly of a terminal and a shift member (20) to improve the shortcoming of the conventional terminal that the structure is complicated and the manufacturing cost is higher. The terminal includes a main body (10) defining a chamber (11) and a metal leaf spring (30) disposed in the chamber (11) for pressing a conductive wire into electrical connection or releasing the conductive wire in response to the operation of the shift member (20). A predetermined section of the shift member (20) is formed with an insertion section (24) and walls (25) defining the insertion section (20). A part of the wall (25) is removed to provide elastic effect for the insertion section (20). The removed part is repositioned on a surface (14) of upper section of the main body (10) to form an interference section (15). After the shift member (20) is pressed down, the interference section (15) is assembled with the insertion section (24).
