Latch Mechanism for Mobile Cable Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wired connections in mobile systems are prone to inadvertent disconnection due to their reliance on friction fit, which is problematic in environments where users' hands are occupied, such as in law enforcement and security operations.
Innovation Solution
A latch mechanism is introduced that includes opposing latch members and bias members to securely engage and maintain a cable connector, preventing unintentional withdrawal by sliding relative to each other to secure the connector within a housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional friction fit connections are used for cables, then the device structure remains simple, but the connection reliability deteriorates due to inadvertent disconnection
Solution Approach 1:
The latch mechanism is divided into separate opposing latch members that can independently engage and disengage from the cable connector. This segmentation allows the connection and release functions to be separated, improving reliability while keeping each individual latch member relatively simple in structure.
Solution Approach 2:
The latch members are designed to be movable rather than fixed, allowing them to dynamically engage with and secure the cable connector. The opposing latch members can slide or pivot to lock into place, providing secure connection while maintaining the ability to release when needed, thus balancing reliability with operational flexibility.
2Reliability
If a secure latch mechanism is implemented, then connection reliability improves, but the ease of operation deteriorates due to requiring intentional user action
Solution Approach 1:
The latch mechanism incorporates self-latching features where the opposing latch members automatically engage and secure the cable connector upon insertion, without requiring user intervention. The design allows the connection to be maintained passively, improving ease of operation during normal use while maintaining high connection security.
3Force
If the latch members are maintained in tension, then the securing force increases, but the force required to operate the latch increases
Solution Approach 1:
The latch mechanism uses multiple opposing latch members that distribute the securing force across multiple contact points on the cable connector. This segmentation allows each individual latch member to operate with reduced force while collectively providing strong overall securing, thus maintaining high holding force while reducing the actuation force needed.

AI summary
Various techniques are provided to secure a connector to a module, for example, for convenient and reliable use in mobile environments. In one example, a system includes a housing and a latch mechanism. The latch mechanism includes first and second opposing latch members that define a cavity configured to receive a cable connector. The latch mechanism also includes first and second bias members configured to maintain the latch members in tension with each other. The latch members are configured to slide relative to each other in response to the bias members to secure the connector relative to the housing. Additional systems and methods are also provided.
