Stackable Enclosure Door Hinge Cable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable wall mount enclosures for telecommunications require complex and cumbersome processes for cable passage between stacked units, often necessitating partial disassembly and reassembly.
Innovation Solution
A design where a second enclosure is stacked and fastened to the side door of the first enclosure using a piano hinge and fastener assemblies, allowing for easy access and cable passage without full disassembly, utilizing grommets and fastener assemblies to secure the side door in a closed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If enclosures are stacked to reduce wall space occupation, then area of stationary object is reduced, but device complexity increases due to required partial disassembly and reassembly
Solution Approach 1:
The enclosure is divided into separable modules (enclosure body, door assembly with hinge, back plate) that can be independently handled during stacking. The door assembly is segmented from the enclosure body via the hinge mechanism, allowing the door to be independently positioned for cable access without requiring complete disassembly of the enclosure structure.
Solution Approach 2:
The hinge mechanism is pre-configured to allow the door to swing open to a substantial angle before stacking begins. This preliminary positioning of the door creates ready access to the cable passage opening, eliminating the need for complex disassembly operations during the stacking process.
2Reliability
If door is kept closed to protect internal components, then reliability is improved, but ease of operation deteriorates due to difficulty of cable passage
Solution Approach 1:
The door is designed as a dynamic component that can transition between closed (protective) and open (accessible) states. The hinge mechanism enables the door to swing open to a substantial angle, dynamically changing from a protective barrier to an accessible interface for cable installation while maintaining security when closed.
Solution Approach 2:
The hinge mechanism serves as an intermediary that mediates between the need for door closure (protection) and the need for cable access. It allows the door to be opened to a controlled substantial angle, providing intermediary access state that balances protection requirements with installation needs.
3Ease of operation
If partial disassembly is required for cable passage, then ease of operation improves for cable access, but loss of time increases due to disassembly and reassembly operations
Solution Approach 1:
The door is pre-positioned in an open state (swung open to substantial angle) before the stacking operation begins. This preliminary action eliminates the need for time-consuming disassembly operations during stacking, as the cable passage opening is already accessible when the enclosures are brought together.
Solution Approach 2:
The hinge mechanism automatically maintains the door in its open position during stacking through its mechanical design, eliminating the need for additional fastening or securing operations. The door's weight and hinge geometry work together to self-maintain the open state, reducing operational time and complexity.

AI summary
A telecommunications enclosure having a door hingedly attached to a chassis. The chassis has a first through-hole configured to have at least one patching panel installed therein. A different enclosure, like the telecommunications enclosure, is mountable on the door. The door is rotatable relative to the chassis between closed and open positions when the different enclosure is mounted thereto. The door allows access to an interior of the chassis when the door is in the open position. The chassis and/or the door may have a second through-hole configured to allow a telecommunications cable connected to the at least one patching panel to pass therethrough and exit the interior of the chassis.
