Tool Storage Case Latch and Cleat Connection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool storage cases lack efficient mechanisms for connecting multiple cases while maintaining optimal storage space and ease of use.
Innovation Solution
A tool storage case system comprising a pair of storage cases that can be releasably connected using a first connection structure with spaced cleats and a second connection structure with spaced receptacles, along with a latch and latch engagement structure for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple storage cases are connected to increase storage capacity, then the quantity of tools that can be stored increases, but the device complexity increases due to additional connection mechanisms
Solution Approach 1:
The connection system is segmented into discrete components: cleats on one case and receptacles on the adjacent case. This segmentation allows for simple, modular connection without complex mechanisms, as each component performs a specific function and can be independently manufactured and assembled.
Solution Approach 2:
The latch mechanism merges the connection and securing functions into a single integrated system. The latch pivots to simultaneously engage with the cleat-receptacle connection, combining the actions of joining and locking into one mechanism that reduces overall system complexity while maintaining secure connection.
2Ease of operation
If connection structures are added to link storage cases, then the ease of operation improves through secure connection, but the interior storage space is reduced
Solution Approach 1:
The connection structures (cleats and receptacles) are positioned at specific locations on the housing members, localized to the connection areas rather than occupying significant interior space. This local placement ensures secure connection while minimizing impact on overall storage capacity.
Solution Approach 2:
The latch mechanism operates in a different dimensional plane from the cleat-receptacle connection. The latch pivots perpendicular to the connection plane, allowing the connection structures to be positioned optimally for security while the latch provides additional securing in a separate spatial dimension, effectively adding functionality without proportionally reducing storage space.

AI summary
A tool storage case system includes a pair of storage cases that can be releasably connected to each other by a latch that extends rearwardly from an exterior side of a back wall of one of the cases no further than a pair of hinges of the case. The latch is located between the pair of hinges and is mounted to the back wall to pivot between a latched position and an unlatched position, with the latch extending rearwardly no further than the pair of hinges with the latch in the latched position.
