Dual-Latch Door Assembly for Cable Trough Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communications cable management systems lack efficient mechanisms for securing and accessing cable troughs, often relying on cumbersome fasteners and limited access methods, which can lead to security issues and hinder maintenance.
Innovation Solution
A door assembly with dual latch mechanisms and actuators that allow for secure closure and easy pivotal opening, enabling access from either side or removal, using a combination of latch pins and toggle arms for secure engagement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic quarter turn fasteners are used to secure the door panel, then the door can be secured to the spacer bracket, but the mechanism is cumbersome and requires releasing all four fasteners to access the cable trough
Solution Approach 1:
The latch mechanism is divided into multiple discrete latch structures (first and second latches with respective latch structures) that can be independently controlled. Each latch can be engaged or disengaged separately, allowing the door to be secured at specific locations rather than requiring all latches to be engaged simultaneously. This segmentation enables selective access while maintaining overall security.
Solution Approach 2:
The latch mechanism incorporates movable latch structures that can transition between engaged and disengaged states. The actuator mechanisms enable dynamic control of each latch's position, allowing the door to be quickly opened or closed by moving latches between positions rather than requiring manual manipulation of multiple fixed fasteners.
2Reliability
If the door panel is secured with multiple fasteners, then security is improved, but the device complexity increases
Solution Approach 1:
Multiple latch structures are combined into an integrated latch mechanism system that operates through coordinated actuation. The first and second latches with their respective latch structures function as a unified system, controlled by actuators that can engage or disengage the latches in a coordinated manner. This merging reduces the operational complexity compared to managing separate fasteners independently.
Solution Approach 2:
The latch mechanism serves multiple functions: it can fully secure the door when both latches are engaged, allow partial access when one latch is disengaged, and provide controlled opening/closing motion. The same latch structures enable both security and accessibility functions, eliminating the need for separate mechanisms for different access scenarios.
3Adaptability or versatility
If the door allows pivotal movement, then access flexibility is improved, but the securing mechanism becomes more complex
Solution Approach 1:
The door assembly is segmented into independently controllable latch zones (first latch near first side edge, second latch near second side edge). Each latch can be disengaged independently to allow pivotal movement from different sides, providing flexible access options without requiring a complex centralized hinge mechanism.
Solution Approach 2:
The latch structures serve as intermediary elements between the door and spacer bracket, mediating both the security function and the pivotal movement function. When latches are engaged, they provide secure attachment; when disengaged, they allow controlled pivotal movement. This intermediary role eliminates the need for separate hinge mechanisms.

AI summary
A communications cable management system includes a support structure and a door assembly. The door assembly includes at least two first latch structures and at least two second latch structures each selectively positionable in a latched position to secure the door body to the support structure. First and second actuators are operable by a user to selectively latch the latch structures such that a door body is secured in a closed position on the support structure, the door body can be removed from the support structure, the door body can be pivoted open about the first pivot axis, or the door body can be pivoted open about a second pivot axis.
