Connector Flexible Brace Elastic Recovery Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with low height suffer from insufficient elastic recovery force, leading to increased insertion resistance when a male housing is inserted into a female housing, and existing designs with dual connection points at the front and rear sides result in uneven elastic recovery forces, causing insertion difficulties.
Innovation Solution
A connector design where the flexible brace is connected to the male housing at both the front and rear sides of the insertion direction, with the rear side brace part providing a larger elastic recovery force to secure fitting and the front side brace part being narrower and thinner to reduce insertion resistance, allowing for a lower connector height while maintaining sufficient elastic recovery force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the connector height is reduced to meet miniaturization demands, then the connector can be used in compact electronic devices, but the elastic recovery force in the flexible brace becomes insufficient
Solution Approach 1:
The flexible brace is divided into two separate connection portions: a front side connection portion and a rear side connection portion. This segmentation allows each portion to contribute to the elastic recovery force, with the rear side portion providing the primary force while the front side portion provides additional support, thereby maintaining sufficient total elastic recovery force even when the overall connector height is reduced.
2Force
If the flexible brace is connected at both front and rear sides to secure elastic recovery force, then sufficient fitting force is obtained, but insertion resistance increases due to the front side brace part contacting the edge of the female housing
Solution Approach 1:
The front side connection portion is designed with a narrower width compared to the rear side connection portion. This local quality difference ensures that the front side portion does not contact the edge of the female housing during insertion, reducing insertion resistance. Meanwhile, the rear side connection portion maintains sufficient width to provide the necessary elastic recovery force for secure fitting.
3Length of stationary object
If the connector height is lowered, then the connector meets compact device requirements, but the latching block cannot obtain sufficient elastic recovery force to fit into the latching hole
Solution Approach 1:
Instead of relying solely on vertical height for elastic recovery, the invention utilizes the longitudinal dimension by connecting the flexible brace at both the front and rear sides of the insertion direction. This dimensional transition allows the rear side connection portion to provide the necessary elastic recovery force for reliable latching, compensating for the reduced vertical height.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector achieves reduced insertion resistance and secure fitting by distributing the elastic recovery force effectively across both the front and rear side brace parts, enabling easy insertion and maintaining a low overall height.
Implementation Method 1
The flexible brace extends from the main body of the male housing in the insertion direction with the ability to flexibly deform in the direction to be closer to the main body. The latching block formed on the flexible brace uses the elastic recovery force to fit into a latching hole formed in the female housing.

AI summary
The male housing of the connector includes a flexible brace that extends in insertion direction of the male housing in a position separated from the main body and is connected to the main body at a front side and a backside of the insertion direction and has a latching block that fits into a latching hole formed on the side of a female housing, formed on a side separated from the main body of a midway part, where the midway part can be flexibly deformed so as to be close to the main body.
