Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables used with electronic products often become entangled when not in use, causing frustration for users due to lack of effective alignment and storage solutions.
Innovation Solution
A magnetized cable with a persistent magnetic field is designed, featuring an elongated flexible magnetized component and conductive wires, where the magnetic field helps align and maintain the cable's coiled state while allowing easy uncoiling, using magnetic particles embedded in a pliable polymer base and enclosed in a sheath for enhanced magnetic attraction and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a magnetized cable is designed to strongly maintain coiled state through persistent magnetic field, then cable alignment and storage efficiency is improved, but difficulty to manually uncoil and ease of operation deteriorates
Solution Approach 1:
The magnetic particle concentration is varied along the cable length, with higher concentration in sections requiring stable coiling and lower concentration in sections requiring easy manipulation. This parameter gradient allows the cable to exhibit different magnetic strengths in different regions, resolving the contradiction between stable storage and easy uncoiling.
Solution Approach 2:
Different portions of the cable are assigned different magnetic properties through selective placement of magnetic particles. The cable transitions from uniform magnetic distribution to non-uniform distribution, where specific segments have enhanced magnetic characteristics tailored to their functional requirements.
2Force
If magnetic particles are densely distributed throughout the cable to strengthen magnetic attraction, then cable alignment capability is improved, but cable flexibility and ease of handling deteriorates
Solution Approach 1:
Magnetic particles are concentrated in specific regions rather than uniformly distributed throughout the entire cable. This localized distribution provides strong magnetic attraction where needed while preserving cable flexibility in other regions.
Solution Approach 2:
The cable employs a composite structure combining magnetic particles with flexible polymer matrix. This composite approach allows the cable to simultaneously exhibit magnetic attraction properties and mechanical flexibility, resolving the contradiction between force and ease of operation.
3Force
If rectangular cross section with large aspect ratio is used to enhance magnetic surface attraction, then magnetic holding force is improved, but cable flexibility and ease of coiling deteriorates
Solution Approach 1:
The cable cross-sectional geometry is optimized by adjusting the aspect ratio of the rectangular profile. This parameter optimization balances the magnetic surface area for attraction with the mechanical flexibility required for easy coiling and handling.

AI summary
A magnetized cable in which the magnetic force of the cable is configured to aid in aligning and maintaining alignment of the cable while the cable is being looped for storage and, when the cable is rolled or looped, the magnetic force will aid in keeping the cable coiled. Embodiments of the magnetized cable include an elongated flexible magnetic component (EFMC) of a pliable polymer such as rubber and/or one or more other suitable materials in combination with magnetic particles comprising iron, neodymium, ferrite, cobalt, nickel, and/or other suitable magnetic elements or compounds. The EFMC may be exposed to a strong magnetic field to produce a permanent magnet. The EFMC may be enclosed within a sheathing material of braided textile yarns or another suitable material.
