Spring Latch Extractor for Stress-Free Electronic Module Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic module mounting systems lack efficient and easy-to-use mechanisms for removably attaching and detaching modules from bases without causing stress or deformation to latch components during unlatching.
Innovation Solution
The use of spring latches and channel-shaped shift members with stiff metal arms that engage the base and transmit unlatching forces without bending, allowing for easy removal by pulling upward on grip elements, which automatically return to their initial positions after removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional latch mechanisms are used for mounting electronic modules, then the module can be securely attached to the base, but the unlatching process requires excessive force causing stress and deformation to latch components
Solution Approach 1:
The latch mechanism is divided into separate functional components: latch arms for engagement, shift members for force transmission, and extractors for operation. This segmentation allows each component to be optimized for its specific function, with shift members designed to transmit forces without bending, preventing deformation while enabling easy removal.
Solution Approach 2:
Shift members act as intermediaries between the extractors and latch arms. These stiff metal components transmit unlatching forces from the extractors to the latch arms without bending, serving as force transmission mediators that prevent deformation of the latch arms while enabling easy module removal.
2Reliability
If stiff shift members are used to transmit unlatching forces without bending, then latch component deformation is prevented, but the mechanism requires a more complex structure with channel-shaped components
Solution Approach 1:
The shift members are designed with specific geometric parameters - channel-shaped cross-sections with optimized dimensions - to achieve the required stiffness for force transmission without bending. This parameter optimization allows the components to be stiff enough to prevent deformation while maintaining a relatively simple structural form.
3Ease of operation
If grip elements are designed for easy manual engagement, then ease of operation is improved, but the elements may be difficult to detect and locate during installation
Solution Approach 1:
The grip elements are designed with visual characteristics that make them easily detectable during installation. The contrasting appearance and positioning of the grip elements allow operators to quickly locate and engage them, solving the detection problem while maintaining ease of operation.

AI summary
An electronic module for mounting on a base includes a module body and a latch extractor assembly having a metal latch member with a spring arm, a shift member and a latch, and an extractor engageable with the shift member for movement of the latch out of engagement with the base.
