Elastic Latch Connector Structure for High Locking Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector designs with semi-circular ring fixed ends for elastic latches lack sufficient strength for applications requiring large locking forces.
Innovation Solution
The elastic latch features a fixed end with an inclined surface greater than 90 degrees relative to the housing, enhancing connection strength and allowing for larger locking forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a semi-circular ring fixed end is used for the elastic latch, then the structure is simple and easy to manufacture, but the connection strength is insufficient for applications requiring large locking forces
Solution Approach 1:
The patent changes the geometric parameters of the fixed end by introducing an inclined surface with a specific angle (greater than 90 degrees) relative to the housing surface. This parameter modification transforms the semi-circular ring structure into a more robust configuration that can withstand larger locking forces while maintaining manufacturing feasibility.
Solution Approach 2:
The patent introduces asymmetry by adding an inclined surface to the fixed end structure. The inclined surface creates an asymmetric geometry that distributes stress more effectively during engagement, improving the connection strength between the elastic latch and the housing compared to the symmetric semi-circular ring design.
2Force
If the fixed end is directly connected to the housing surface, then the manufacturing process is simple, but the locking force capacity is limited
Solution Approach 1:
The patent modifies the connection geometry by introducing an inclined surface with an angle greater than 90 degrees between the fixed end and the housing surface. This parameter change enables the structure to transmit and withstand larger locking forces while still being manufacturable using conventional processes.
Solution Approach 2:
The patent adds a dimensional element by introducing an inclined surface that creates a three-dimensional engagement geometry. This dimensional change allows the fixed end to engage with the housing in a more robust manner, increasing locking force capacity beyond the simple planar connection of the semi-circular ring.

AI summary
A connector includes a housing and an elastic latch. The elastic latch includes an elastic cantilever having a free end, a fixed end connected to the housing, and a main part extending between the free end and the fixed end. The fixed end has an inclined surface extending inclined with respect to a surface of the housing. An angle between the inclined surface and the surface of the housing is greater than 90 degrees.
