Cable Holding Device With Overlapping Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable holding devices only restrict movement in the radial direction of cables, failing to effectively manage movement in the extending direction, which is necessary for applications like underwater environments where cables need secure fixation.
Innovation Solution
A cable holding device comprising a first member with a through hole, a second member with a corresponding through hole, and a fixing member that overlaps the holes to securely hold the cable by the inner peripheries of both holes, allowing for movement restriction in both radial and extending directions through adjustable positioning and fixation mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single through hole is used to hold the cable, then the device structure is simple, but the cable movement in the extending direction cannot be restricted
Solution Approach 1:
The single through hole is segmented into two separate through holes (first through hole in the first member, second through hole in the second member). This segmentation allows each hole to contribute to restricting cable movement in different directions, with the first hole restricting radial movement and the second hole restricting extending direction movement, thereby solving the contradiction between structural simplicity and fixation reliability.
Solution Approach 2:
The solution transitions from a single-dimensional hole to a two-dimensional overlapping hole configuration. The first through hole and second through hole are positioned at different locations and overlap with each other, creating a multi-dimensional constraint system that restricts cable movement in both radial and extending directions simultaneously.
2Ease of operation
If the second through hole completely overlaps the first through hole, then the cable can pass freely, but the cable cannot be held securely in the extending direction
Solution Approach 1:
Instead of complete overlap which would allow free cable passage, the invention uses partial overlap where the second through hole overlaps only a portion of the first through hole. This partial overlap creates sufficient friction and mechanical interference to hold the cable securely in the extending direction while still allowing the cable to be installed by passing it through the aligned portions.
3Device complexity
If only radial movement restriction is implemented, then the holding device is simple, but cable fluctuations can occur causing gaps and water ingress
Solution Approach 1:
The holding mechanism is segmented into two functional components: the first member with the first through hole that restricts radial movement, and the second member with the second through hole that restricts extending direction movement. This segmentation addresses both movement directions separately, preventing cable fluctuations that could lead to gaps and water ingress in pressurized environments.
Solution Approach 2:
The overlapping through holes act as an intermediary mechanical constraint between the cable and the holding device. The partial overlap creates a friction-based intermediary force that resists cable movement in the extending direction, preventing cable fluctuations without requiring direct contact or additional sealing components.

AI summary
A cable holding device for holding a cable, includes a first member, a second member and a fixing member. The first member has a first through hole through which the cable is to pass. The second member has a second through hole through which the cable is to pass. The fixing member fixes the second member to the first member in such a condition that the second through hole partially overlaps the first through hole to hold the cable by an inner periphery of the first through hole and an inner periphery of the second through hole.
