Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable connectors face challenges in improving workability of insertion and extraction due to high contact pressure requirements, which compromise reliability and ease of use, as reducing contact pressure leads to increased risk of slight sliding and abrasion.
Innovation Solution
The design incorporates a square wave-shaped spring portion with linear upper and lower piece portions and extending portions, reducing displacement load and stress distribution, allowing for lower contact pressure and improved workability while maintaining reliability by preventing slight sliding of the contact portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact pressure of the contact portion is set high to maintain contact position with the connection object, then the reliability of conductive connection is improved, but the workability of insertion and extraction deteriorates
Solution Approach 1:
The spring portion is divided into multiple linear spring pieces (upper piece portion, lower piece portion, first extending portion, second extending portion) connected by corner portions. This segmentation allows stress to be distributed across multiple segments rather than concentrated in a single arc-shaped bent portion, enabling the spring to achieve the necessary contact pressure while requiring lower insertion force.
Solution Approach 2:
The invention transitions from an arc-shaped curved bent portion to linear spring pieces connected by corner portions. This geometric change from continuous curvature to segmented linear segments with sharp corners creates more efficient stress distribution paths, reducing the displacement load while maintaining the elastic deformation function.
2Ease of operation
If the contact pressure of the contact portion is reduced to improve workability of insertion and extraction, then the ease of operation is improved, but the risk of slight sliding increases
Solution Approach 1:
By segmenting the spring portion into multiple linear pieces connected by corner portions, the invention achieves a more efficient elastic structure that can generate sufficient contact pressure with lower insertion force. This allows the contact portion to maintain reliable contact pressure for preventing sliding while requiring less force for insertion and extraction.
Solution Approach 2:
The invention changes the geometric parameters of the spring portion from an arc-shaped bent portion to linear spring pieces with specific corner connections. This parameter change optimizes the stress distribution characteristics, enabling the spring to achieve the required contact pressure threshold for preventing sliding with reduced displacement load.
3Reliability
If the spring portion is formed with a bent portion curved in an arc shape to absorb displacement, then the function of absorbing displacement is achieved, but the displacement load becomes large
Solution Approach 1:
The spring portion is segmented into multiple linear spring pieces (upper piece portion, lower piece portion, first extending portion, second extending portion) connected by corner portions. This segmentation creates multiple stress distribution paths that are more efficient than a single arc-shaped bent portion, reducing the displacement load while maintaining the elastic deformation function for absorbing displacement.
Solution Approach 2:
The invention replaces the arc-shaped curved bent portion with linear spring pieces connected by corner portions. This geometric transformation from continuous curvature to segmented linear segments with sharp corners optimizes the stress distribution, reducing the displacement load required for elastic deformation while maintaining the displacement absorption function.

AI summary
To reduce the displacement load of a spring portion in order to improve the workability of insertion and extraction of a movable connector. A spring portion has an upper piece portion and a lower piece portion having a linear shape, and is formed in such a square wave shape that an outer vertical piece portion having a linear portion extends from a first end of the upper piece portion, a central vertical piece portion having a linear shape and connected to a first end of the lower piece portion extends from a second end of the upper piece portion, and an inner vertical piece portion having a linear shape extends from a second end of the lower piece portion.
