Module Latch Mechanism with Spring-Loaded Bolt Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for fixing and releasing modules in module mounting frames are inefficient, often requiring constant spring actuation to insert or remove modules, and do not easily accommodate modules of different dimensions or sizes.
Innovation Solution
A mechanism featuring a latch and spring system with a bolt holder that can move between holding and release positions, allowing the latch to be easily moved between locked and open positions using the spring's bias, facilitating module insertion and removal without constant spring actuation, and accommodating modules of varying dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-loaded plunger mechanism is used to fix modules, then modules can be automatically snapped into place during insertion, but constant spring actuation is required to insert or remove modules
Solution Approach 1:
The patent extracts the spring mechanism from continuous operation and confines it to a single latching action. The spring-loaded plunger is held in a retracted position by a latch during insertion, then released to perform a single snapping action to secure the module. This eliminates the need for constant spring actuation while maintaining the automatic snap-in function.
Solution Approach 2:
The latch mechanism preliminarily restrains the spring-loaded plunger in a retracted position before module insertion. This preliminary action prepares the mechanism for the upcoming latching operation, allowing the module to be inserted without resistance from the spring, and then the latch is released to perform the securing action.
2Reliability
If a tool-operated plunger mechanism is used for module removal, then modules can be securely fixed, but the removal process becomes cumbersome and time-consuming
Solution Approach 1:
The latch mechanism is designed to be manually operable without requiring external tools. The latch can be directly actuated by hand to release the spring-loaded plunger, enabling quick module removal. This self-service design eliminates the need for tool-operated plungers while maintaining secure fixation through the spring mechanism.
Solution Approach 2:
The fixing mechanism is segmented into two independent functions: the spring-loaded plunger provides secure fixation, while the separate latch mechanism provides quick release capability. This segmentation allows each component to specialize in its function, with the latch enabling rapid tool-free operation for module removal.
3Strength
If conventional bolts or screws are used to fasten modules, then secure fixation is achieved, but the mechanism lacks flexibility for modules of different dimensions
Solution Approach 1:
The mechanism uses a dynamic spring-loaded plunger that can adapt its position and force application to modules of different dimensions. Unlike fixed-position bolts or screws, the spring allows the plunger to move and adjust, providing consistent securing force across various module sizes while maintaining strong fixation.
Solution Approach 2:
The spring-loaded plunger mechanism serves multiple functions: it provides secure fixation for different module sizes, enables automatic snap-in during insertion, and works with the latch to provide quick release. This universal mechanism replaces the need for dimension-specific fastening solutions like conventional bolts or screws.

Function Achieved in This Case
This mechanism simplifies the insertion and removal of modules by reducing the need for constant spring actuation and allows for flexible accommodation of modules of different sizes, enhancing usability and installation space efficiency in module mounting frames.
Implementation Method 1
A spring is provided. The mechanism further includes a latch holder which can be reciprocated between a holding position in which it retains the latch against the bias of the spring
