Retention Projection Connector Assembly for Stable Lock-Free Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies for wearable devices require complex structures with locking mechanisms to maintain a stable fitting state, which can be cumbersome and prone to failure.
Innovation Solution
A connector assembly with a simple structure that includes a first connector and a second connector fitted along a fitting direction, where the first connector has a retention projection and contacting portions that accommodate and securely connect to the second connector, maintaining the fitting state without a dedicated locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to maintain the fitting state, then the stability of the connector is improved, but the device complexity increases
Solution Approach 1:
The patent combines the retention function and electrical contact function into a single integrated retention projection structure. The retention projection simultaneously provides mechanical retention through its engagement with the projection accommodating portion and electrical contact through the contacting portions formed on its lateral surfaces, eliminating the need for separate locking mechanisms and contact elements.
Solution Approach 2:
The retention projection serves multiple functions: it provides mechanical retention by engaging with the projection accommodating portion, establishes electrical contact through its contacting portions, and maintains the fitting state without requiring additional dedicated locking components. This multi-functional design resolves the contradiction by achieving reliability through a unified structure rather than adding complexity.
2Reliability
If a locking mechanism is added to prevent disconnection, then the reliability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The retention projection integrates retention and contact functions into a single manufacturable component. The contacting portions are formed directly on the lateral surfaces of the retention projection, allowing for simplified manufacturing processes compared to assembling separate locking mechanisms and contact elements.
Solution Approach 2:
The retention projection is designed with distinct functional regions: the retention portion for mechanical engagement and the contacting portions for electrical contact. This segmentation allows each region to be optimized for its specific function while maintaining overall manufacturing simplicity through integrated formation.
3Reliability
If multiple contacting portions are added to ensure reliable electrical connection, then the reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple contacting portions are integrated into the single retention projection structure rather than being separate components. The first, second, and third contacting portions are formed on different surfaces of the retention projection, providing multiple electrical contact paths while maintaining a unified structural element that reduces overall device complexity.

AI summary
A connector assembly includes a first connector and a second connector, the first connector having a first contacting portion disposed on a lateral surface of a retention projection, a second contacting portion disposed on a lateral surface of the retention projection opposite to the lateral surface having the first contacting portion thereon at a position closer to a base portion of the retention projection than the first contacting portion is, and a third contacting portion disposed on the first exposed surface at a position away from the lateral surface, having the first contacting portion thereon, of the retention projection in an opposite direction from the second contacting portion.
