Interlocking Cable Structure for Tangle-Resistant Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables frequently become tangled or knotted due to their inherent design, leading to inconvenience and inefficiency in storage and usage.
Innovation Solution
The implementation of interlocking elements, similar to those found in building blocks like Legos, which allow cables to securely fit into each other, preventing tangling and knotting by restricting movement and allowing for controlled folding and storage configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are made flexible and movable for ease of use, then ease of operation is improved, but cables become prone to tangling and knotting
Solution Approach 1:
The cable is divided into multiple segments with interlocking elements (protrusions and recesses) that allow controlled movement between segments while preventing random tangling. Each segment can move independently but locks when connected to another segment, maintaining flexibility for use while preventing chaotic entanglement.
Solution Approach 2:
Cable segments are designed to nest within each other when connected, with protrusions fitting into recesses of adjacent segments. This nesting arrangement allows the cable to be compact when stored while maintaining ease of movement during use, resolving the contradiction between flexibility and tangle resistance.
2Stability of the object's composition
If interlocking elements are added to prevent tangling, then tangle resistance is improved, but device complexity increases
Solution Approach 1:
Instead of making the entire cable structure complex, interlocking elements are applied only at specific locations along the cable length. The majority of the cable remains simple and flexible, with complexity localized to discrete interlocking segments that provide tangle resistance without overwhelming the overall design.
Solution Approach 2:
The cable incorporates interlocking elements at intervals rather than continuously along its entire length. This partial application of the interlocking mechanism provides sufficient tangle resistance for practical use while minimizing the added complexity and material requirements compared to a fully interlocked design.

AI summary
Cables, including electrical cables. The cables are provided with a series of elements designed to interlock with each other when a first length of cable is pressed against a second length of cable, the element including protrusions and spaces between the protrusions. A user folds a length of cable on itself or on another cable, snugly pressing the protrusions into the spaces, to store the cable, or to restrict the movement of the cable during use. In this manner, movement of the cable is restricted into the configuration set by the user, and preventing the cable from becoming tangled, knotted, or so forth.
