Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable enclosures for signal carrying cables, such as fiber optic cables, often require complex and costly door catch mechanisms that can be inefficient and prone to failure, particularly in environments where secure cable management is crucial.
Innovation Solution
A simpler and cost-effective door catch arrangement using magnetic catch components integrated with flared, radius-limiting cable guides in open-ended cable ports, where a magnet or ferromagnetic catch member is retained in the cable guide's recess to securely hold the door closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanical catch mechanisms are used to secure enclosure doors, then door security and reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces complex mechanical catch mechanisms with a magnetic catch system. Magnets are embedded in the cable guide body and ferromagnetic catch members are attached to the door, creating a magnetic attraction force that secures the door without requiring complex mechanical linkages, springs, or latches. This substitution of mechanical system with magnetic field-based system directly reduces device complexity while maintaining door security reliability.
Solution Approach 2:
The patent merges the cable guide function with the door catch function into a single integrated component. The cable guide body simultaneously serves as the structural guide for cables and as the mounting structure for the magnets that provide door catching capability. This merging eliminates the need for separate catch mechanisms, reducing overall device complexity while maintaining door security.
2Reliability
If traditional mechanical locks and catches are used, then door security is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive mechanical locks and catches with inexpensive magnets and ferromagnetic components. The magnets can be standard commercial magnets embedded in molded plastic cable guides, and the ferromagnetic catch members can be simple steel plates or rivets attached to the door. This substitution dramatically reduces manufacturing costs while maintaining door security reliability.
Solution Approach 2:
The patent uses inexpensive, readily available magnetic components and ferromagnetic pieces that can be easily manufactured and replaced if needed. These cheap components provide sufficient door security without requiring expensive precision-machined mechanical locks, making the enclosure more cost-effective to manufacture and maintain.
3Device complexity
If simple door catch arrangements are used, then device complexity and cost are reduced, but door security and reliability deteriorate
Solution Approach 1:
The patent uses magnetic fields instead of complex mechanical systems to achieve both simplicity and reliability. The magnetic attraction force between the magnets in the cable guide and the ferromagnetic catch members on the door provides secure door closure without requiring complex mechanical linkages. This magnetic approach achieves high reliability with minimal complexity.
Solution Approach 2:
The cable guide body serves multiple functions: it guides cables through the enclosure opening and simultaneously houses the magnets that provide door catching capability. This multi-functionality eliminates the need for separate catch mechanisms, achieving both simplicity and reliable door security through an integrated design that reduces the number of components while maintaining security function.

AI summary
A door catch arrangement for cable enclosures incorporates magnetic catch components on the door and on an adjacent open-ended, flared, radius-limiting cable guide installed in at least one open-ended cable port of the enclosure. The cable guide itself covers the rim of the cable port and has two spaced legs, each leg having an end face disposed at the open end of the cable port. A recess in one of the end faces holds a magnet. In its closed position, the door blocks the end of the cable port and a ferromagnetic catch portion on the door opposes the magnet, which keeps the door closed. The positions of the magnet and the ferromagnetic catch portion can be reversed.
