Handle-Integrated Latch Assembly for One-Handed Module Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular systems for tool storage utility modules lack efficient mechanisms for detachable and rigid coupling, particularly in handling and transport, as existing interfaces often require users to adjust hand positions to actuate latches, complicating the decoupling process.
Innovation Solution
The development of utility modules with integrated handles and latches that allow direct engagement of an interface to actuate the latch between extended and retracted positions, facilitating easy decoupling and transport without requiring hand position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the latch interface is integrated into the handle structure, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The latch interface is merged with the handle structure, allowing the interface to be positioned within or integrated into the handle. This enables the user to actuate the latch while maintaining a consistent grip on the handle, eliminating the need to adjust hand positions and simplifying the decoupling operation.
2Ease of operation
If the interface is positioned in front of the housing, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The interface is pre-positioned in front of the housing at an accessible location. This preliminary positioning allows the user to engage and actuate the latch interface without needing to adjust their grip or reach into difficult-to-access areas, improving operational ease while the positioning tolerances are managed through design.
3Reliability
If the latch actuates between extended and retracted positions, then reliability is improved, but device complexity increases
Solution Approach 1:
The latch mechanism is segmented into distinct extended and retracted positions, allowing it to reliably engage and disengage the coupling between utility modules. This segmentation provides clear stable states for the latch, improving reliability while the overall complexity is managed through the simple linear motion design.

AI summary
Various latch assemblies are provided to facilitate engaging and disengaging utility modules within a modular system. The latch assemblies permit users to actuate latches from an extended position to a retracted position, thereby permitting disengagement of the utility modules, while the hand of the user is in position to hold the now decoupled utility module.
