Cable Fastening Device Segmentation for Waterproof Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for cables and fibers lack proportional sealed strength, leading to breakage when repeatedly drawn out, and fail to provide adequate waterproofing, especially in harsh weather conditions.
Innovation Solution
A fastening device comprising a first casing, inner holding part, waterproof screw annulus, positioning nut, connecting casing, inner buckled nut, resilient washer, and constricting gasket, which provides multiple retention points and waterproofing mechanisms to securely hold cables or fibers in place, preventing shifting or breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single connecting portion is used for fastening the cable, then the device structure is simple, but the cable cannot be retained well-proportioned and waterproofing is insufficient
Solution Approach 1:
The fastening device is divided into multiple functional segments: a clamp assembly with pawls for mechanical retention, a collar with sealing surfaces for waterproofing, and a positioning system with multiple connecting portions. Each segment performs a specific function, and their combination provides both simple operation and reliable cable retention with proportional sealed strength.
2Ease of operation
If cables are fastened with limited connecting portions, then installation is easy, but the cables will be broke off when drawn out repeatedly
Solution Approach 1:
The fastening device employs a nested structure where the collar is positioned within the clamp assembly, and the sealing elements are integrated within the collar structure. This nested arrangement allows multiple retention mechanisms to work together in a compact configuration, providing strong cable retention while maintaining ease of installation through a single assembly operation.
3Volume of moving object
If a narrow connecting portion is used, then the device is compact, but it cannot prevent vapor from getting inside
Solution Approach 1:
The collar incorporates flexible sealing surfaces and gasket elements that conform to the cable and housing interfaces. These flexible sealing elements create vapor-tight seals within the compact collar structure, preventing vapor penetration while maintaining a compact device footprint through the use of deformable sealing materials.
Applied Scientific Principles

AI summary
A fastening device is provided for fastening cables, fibers or wave hoses in position with multiple ways, and for waterproof capability. The fastening device includes a first casing, an inner holding part, a waterproof screw annulus, a positioning nut, a connecting casing, a second casing, an inner buckled nut, a resilient washer, and a constricting gasket. The first casing and the second casing are respectively engaged with the waterproof screw annulus and the connecting annulus. The first casing and the second casing take force to the wave hose for holding the cable or fiber in place in multiple ways, and avoid shifting or breaking off from drawing outside.
