Solution Overview
Problem
Conventional switch wiring apparatuses face difficulties in rapid and secure insertion and extraction of conductor wires, often requiring complex structures and increasing the product volume, which complicates manufacturing and operation, especially in environments with vibrations that can loosen screws.
Innovation Solution
A contact module design featuring a housing with a middle pole and wiring unit body, where the middle pole moves up and down to connect or disconnect with the wiring unit, and a pressing part allows quick withdrawal of the conductor wire, integrated with a spring and contact current bar for secure and efficient operation, without increasing the product volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw mechanism is used to secure conductor wires, then the connection is reliable, but the operation becomes troublesome and time-consuming due to alignment requirements
Solution Approach 1:
The patent extracts the screw mechanism from the housing and replaces it with a pressing part that directly presses the conductor wire against the electrical joint. This eliminates the need for screw alignment and manual screwing operations, making the wiring process much more convenient while maintaining reliable electrical connection through the pressing mechanism.
Solution Approach 2:
The pressing part is designed to automatically press the conductor wire against the electrical joint when the housing is assembled, without requiring additional manual intervention for alignment or tightening. The spring-loaded pressing part self-adjusts to maintain proper contact pressure, eliminating the need for operator skill in alignment.
2Ease of operation
If guide grooves, guide bars and springs are added to improve screw alignment, then the operation becomes easier, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent completely removes the screw mechanism and associated guiding structures (guide grooves, guide bars, springs) from the design. By replacing the screw mechanism with a pressing part, the need for alignment-guiding features is eliminated, significantly simplifying the overall structure while maintaining ease of operation.
3Ease of operation
If the housing volume is increased to accommodate guiding structures, then the alignment operation is facilitated, but the miniaturization trend is hindered
Solution Approach 1:
By removing the screw mechanism and replacing it with a compact pressing part, the patent eliminates the need for additional space required for guide grooves, guide bars, and springs. This allows the housing to maintain a compact size consistent with miniaturization trends while still achieving easy wire insertion and secure connection.
4Ease of operation
If a metal elastic piece is used to press the conductor wire, then the screw mechanism is replaced, but the manufacturing complexity increases due to special shaping requirements
Solution Approach 1:
The pressing part is designed as a simple, easily manufacturable component that can be made from common materials. Rather than using complexly-shaped metal elastic pieces requiring special bending and opening formation, the pressing part uses straightforward pressing surfaces that can be integrated into the housing or made as simple separate components, significantly reducing manufacturing complexity.
