Staggered Projections in Cable Enclosure Prevent Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable enclosures fail to securely hold cables in place, especially when cables come into contact with each other, leading to easy disengagement during installation.
Innovation Solution
A cable enclosure design featuring staggered first and second projections on the cover and base, respectively, which extend into the cable insertion opening, ensuring that the sum of their lengths exceeds the gap length, preventing disengagement by ensuring cables come into contact with these projections when force is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are enclosed using conventional cable securing apparatus with slits and opposite plates, then cables can be secured in place, but cables may easily disengage when they come in contact with each other during installation
Solution Approach 1:
The cable enclosure is divided into a base and a cover that can be separately assembled, with the cable insertion opening formed between them. This segmentation allows for easier cable installation while maintaining secure holding through the coordinated action of projections on both base and cover.
Solution Approach 2:
The first projections on the cover and second projections on the base are arranged in a staggered asymmetric pattern, with their combined projecting length exceeding the gap length of the cable insertion opening. This asymmetric arrangement prevents cables from disengaging while allowing easy insertion during installation.
2Ease of operation
If the cable insertion opening gap is made larger to allow easier cable insertion, then cable installation becomes easier, but cables may disengage more easily
Solution Approach 1:
The first and second projections are pre-positioned on the cover and base respectively, arranged in a staggered manner before assembly. Their combined projecting length is designed to exceed the gap length, creating preliminary mechanical interlocking that prevents cable disengagement while maintaining easy insertion.
3Stability of the object's composition
If conventional cable securing structures are used, then cable enclosure is achieved, but cables may disengage when contacted during work
Solution Approach 1:
The cable enclosure combines the base and cover as composite structural elements, with staggered projections on both components working together. This composite structure provides enhanced cable position stability and prevents disengagement while maintaining enclosure integrity.

AI summary
A cable enclosure includes a base, a cover configured to cover the base to allow a cable to be enclosed between the cover and the base, and a cable insertion opening formed between a side edge of the base and a side edge of the cover to allow the cable to be inserted therethrough, wherein the cover has a plurality of first projections projecting into the cable insertion opening from the side edge of the cover toward the base, wherein the base has a plurality of second projections projecting into the cable insertion opening from the side edge of the base toward the cover, and wherein the first projections and the second projections project in a staggered manner, such that a sum of a projecting length of the first projections and a projecting length of the second projections is longer than a gap length of the cable insertion opening.
