Dual Latch System for Telecommunications Module Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications module enclosures with rail systems are overly complex and costly, requiring a more efficient and cost-effective latching mechanism to secure and remove modules from panels.
Innovation Solution
A latch system comprising an outer latch and an inner latch, both configured to provide multiple latching points, with deflection surfaces and tapered arms allowing for secure mounting and easy removal of modules from either the front or rear, utilizing a tether for independent movement and pressure points for secure engagement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rail system is used to mount modules, then modules can be securely mounted to the panel, but the system becomes overly complex and costly
Solution Approach 1:
The latch system is divided into two independent latches (outer latch and inner latch) that can be individually actuated. Each latch provides separate engagement points on the panel, allowing the module to be securely mounted through distributed latching points rather than a complex continuous rail system. The latches can be independently controlled to engage or disengage from the panel.
Solution Approach 2:
The invention extracts the essential latching function from the complex rail system, isolating only the necessary engagement and retention mechanisms. By removing unnecessary rail components and keeping only the critical latching elements (latch arms, engagement points, and actuation mechanisms), the system achieves secure mounting with reduced complexity.
2Reliability
If a rail system is used to mount modules, then modules can be securely mounted to the panel, but the system becomes costly
Solution Approach 1:
The module is divided into separable latch components (outer latch assembly and inner latch assembly) that can be manufactured independently and assembled. This segmentation allows for simpler, more cost-effective manufacturing of individual latch parts compared to a continuous rail system, while maintaining secure mounting through multiple engagement points.
Solution Approach 2:
The latch system uses simple, easily replaceable latch arms and engagement points that can be manufactured at low cost. If a latch component wears or fails, only that individual component needs replacement rather than replacing an entire rail system, reducing long-term maintenance and manufacturing costs.
3Reliability
If multiple latching points are provided, then secure engagement is achieved, but the latching mechanism becomes more complex
Solution Approach 1:
Multiple latching points are achieved by dividing the latching function into separate outer and inner latches, each with its own engagement points. The outer latch provides first and second engagement points, while the inner latch provides a third engagement point. This segmentation allows multiple latching points to be achieved through simple, independent latch components rather than a complex integrated mechanism.
Solution Approach 2:
Instead of using a single complex latch to provide multiple engagement points, the invention inverts the approach by using multiple simple latches (outer and inner) that each provide one or more engagement points. This inversion simplifies the individual latch mechanisms while achieving the same overall engagement reliability through distributed latching points.

AI summary
A latch configured to secure a module to a panel. The latch includes an outer latch and an inner latch configured to move independently of the outer latch. The outer latch and the inner latch are configured to provide at least two latching points between the latch and the panel.
