Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional metal leaf spring and conductive component structure is used, then the device is simple in structure, but the pressing force is insufficient for large-diameter conductive wires leading to poor contact and increased impedance
Solution Approach 1:
The conductive component is divided into multiple functional parts: a plate body for structural support, a restriction body with base section and arms for positioning, and multiple pressing elements including metal leaf spring and elastic pressing member. This segmentation allows each part to contribute specifically to generating and distributing pressing force on the conductive wire, solving the insufficient pressing force problem while maintaining reasonable structural complexity through functional specialization.
Solution Approach 2:
The device combines different materials with complementary properties: the conductive component uses conductive material for electrical connection, the elastic pressing member uses elastic material for continuous pressure application, and the insulation case uses insulating material for safety. This composite material approach enables the structure to simultaneously achieve electrical conductivity, mechanical elasticity, and insulating protection, resolving the contradiction between pressing force and structural complexity.
2Reliability
If conventional metal leaf spring alone is used to press the conductive wire, then the structure is simple, but the conductive wire rear end warps up due to leverage effect reducing contact area and increasing impedance
Solution Approach 1:
The restriction body acts as an intermediary structure between the metal leaf spring and the conductive wire. It includes a base section connected to the plate body, arms extending from the base, and positioning sections that guide and stabilize the conductive wire. This intermediary structure prevents the wire rear end from warping by providing lateral support and proper positioning, thereby maintaining stable contact area and reliability without excessive structural complexity.
Solution Approach 2:
The restriction body extends in multiple spatial dimensions: the arms extend horizontally from the base section to provide lateral positioning, while the pressing elements apply force vertically on the conductive wire. This multi-dimensional structural arrangement prevents wire warping by constraining the wire in both horizontal and vertical directions, improving contact stability without significantly increasing overall structural complexity.
3Force
If additional leaf spring is added behind the metal leaf spring to increase pressing force, then the pressing force improves, but the device complexity increases and it is only applicable to specific conductive wire sizes
Solution Approach 1:
The conductive component structure is designed with universal adaptability to accommodate conductive wires of different diameters. The restriction body with its base section and arms provides a flexible positioning framework, while the elastic pressing member can adjust its pressing force according to the wire diameter. This multi-functional design allows the same structure to effectively press both small and large diameter wires, improving versatility while maintaining sufficient pressing force through the cooperative action of multiple pressing elements.
4Ease of operation
If the conductive wire is bent outside the case for wire trimming, then the wire layout flexibility improves, but the leverage effect causes the wire rear end to warp up reducing contact area and raising temperature
Solution Approach 1:
The restriction body and positioning sections perform preliminary action by guiding and stabilizing the conductive wire before the wire trimming operation occurs. The arms and positioning sections pre-position the wire to prevent excessive bending and warping during subsequent trimming operations. This preliminary positioning action maintains adequate contact area between the wire and conductive support, preventing temperature rise due to poor contact, while still allowing necessary wire layout flexibility.

AI summary
A conductive component structure of conductive wire connection device is more securely assembled with the conductive wire to enhance the electro-conduction performance. The conductive component includes a main body in the form of a plate body and a restriction body connected on the main body. The restriction body has a base section, a first arm and a second arm connected with the base section and free sections connected with the first and second arms, which together provide elastic holding action force for the restriction body. When the conductive wire is plugged into the case into contact with the conductive component, the rear end of the conductive wire is at least securely pressed between the first and second arms of the restriction body without deflecting or swinging due to external force.
