Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing probe pins lack durability, necessitating improvements to enhance their structural integrity and longevity.
Innovation Solution
A probe pin design featuring a first and second contact point spaced apart in a first direction, with a support portion and elastic connection between them, and an elastic portion that expands and contracts in the first direction, with a support portion and an elastic connection between them, and an elastic connection between them, and an elastic portion that expands and contracts in the first direction, and a first and second curved portion that are alternately positioned in the first direction, and a first imaginary straight line that is inclined with respect to the center line, and a second curved portion that is positioned on the opposite side of the first curved portion in the second direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional probe pin structure is used, then the device complexity is low, but the durability is insufficient
Solution Approach 1:
The elastic portion is divided into multiple curved portions (first curved portions and second curved portions) that are alternately arranged along the center line. This segmentation allows the elastic portion to distribute and balance stress more effectively during expansion and contraction, thereby improving durability without significantly increasing overall structural complexity
Solution Approach 2:
The elastic portion incorporates multiple curved portions with specific geometric configurations. These curved structures enable smoother stress distribution and more efficient elastic deformation compared to straight-line configurations, enhancing durability while maintaining a relatively simple overall structure
2Reliability
If the elastic portion dimensions are increased to improve stress resistance, then the durability improves, but the device complexity increases
Solution Approach 1:
The curved portions are strategically positioned at specific locations along the elastic portion where stress concentration is most likely to occur. This local quality approach enhances stress resistance at critical points without requiring uniform increases in dimensions throughout the entire elastic portion, thereby avoiding excessive dimensional complexity
Solution Approach 2:
The curved portions with optimized radii and positions provide enhanced stress resistance through geometric configuration rather than simply increasing the overall size of the elastic portion. This curvature-based approach improves stress resistance while maintaining controlled dimensional complexity

AI summary
A probe pin includes: a first contact point; a second contact point; a support portion; and an elastic portion connected to the first contact point and the support portion. The elastic portion includes: a plurality of first curved portions; and at least one second curved portion positioned on an opposite side of the plurality of first curved portions with respect to a center line and that protrudes in a direction opposite to the plurality of first curved portions in a second direction. The plurality of first curved portions and the at least one second curved portion are alternately positioned in a first direction. A first imaginary straight line is inclined with respect to the center line, the first imaginary straight line being an imaginary straight line that connects points farthest from the center line in the second direction of two first curved portions adjacent in the first direction.
