Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connectors with a plunger inside a tube are prone to a stacking phenomenon, leading to poor connections, while tubeless structures lack robustness and sealing performance.
Innovation Solution
A connector design featuring a bottomed cylindrical tube with a spring pin that integrates a contact point, contact portion, and elastic deformation portion as a continuous member, surrounded by the tube, eliminating the need for separate plunger and spring components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plunger inside a tube structure is used to achieve electrical conductivity, then electrical connection is achieved, but a stacking phenomenon occurs causing poor connection
Solution Approach 1:
The patent merges the plunger and spring into a single integrated spring pin component. The spring pin includes an elastic portion that provides spring functionality and a contact point portion that provides electrical contact, eliminating the need for separate plunger and spring components. This integration prevents the stacking phenomenon while maintaining electrical connection reliability.
2Object-generated harmful factors
If a tubeless structure with folded thin plate is used to eliminate stacking phenomenon, then stacking is prevented, but robustness and sealing performance deteriorate
Solution Approach 1:
The patent maintains the tube structure to provide robustness and sealing performance while integrating the spring functionality directly into the contact component. The tube houses the spring pin, and the spring pin's integrated elastic portion provides the necessary mechanical compliance without requiring a separate plunger, thus preventing stacking while maintaining structural integrity.
3Reliability
If separate plunger and spring components are used to achieve electrical contact with elastic force, then electrical conductivity is achieved, but device complexity increases
Solution Approach 1:
The patent combines the plunger and spring into a single spring pin component that includes both the elastic portion (providing spring functionality) and the contact point portion (providing electrical contact). This integration reduces component count and assembly complexity while maintaining the electrical conductivity and elastic force necessary for reliable connection.
