Magnetic Cable Wrapping Layer for Compact Adjustable Coiling

Solution Overview

Problem

Conventional magnetic data cables are cumbersome to store due to their rigid structure and limited flexibility, leading to increased diameter and weight, making them difficult to wind and store efficiently, especially in narrow spaces.

Innovation Solution

A magnetic data cable with a wrapping material layer containing a magnetic material layer made from a mixture of plastic and magnetic powder, which allows for adjustable coil diameter and continuous magnetic attraction, reducing the risk of damage and enabling easier storage by integrating the magnetic material throughout the layer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If magnetic rings or magnet blocks are used in conventional magnetic data cables, then magnetic attraction for storage is achieved, but the cable diameter increases by at least 3mm and weight increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent uses composite magnetic powder particles mixed with plastic material to create a magnetic wrapping layer. This composite approach distributes magnetic properties throughout the entire wrapping layer rather than using discrete magnetic components, achieving magnetic attraction while significantly reducing cable diameter and weight compared to conventional magnetic rings or blocks

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent changes the physical state and distribution of magnetic material from discrete large components (rings/blocks with wall thickness >1.5mm) to fine powder particles distributed throughout the wrapping layer. This parameter change in magnetic material configuration enables strong magnetic attraction with much smaller overall dimensions

AI summary

A magnetic data cable includes a cable body and data connectors. The data connectors are respectively connected to two ends of the cable body. The cable body includes a cable core and a wrapping material layer wrapped around the cable core. At least one layer of the wrapping material layer is a magnetic material layer. When the magnetic data cable is wound into coils, each two adjacent coils arranged from top to bottom or each two adjacent coils arranged from left to right are magnetically attracted to each other by the magnetic material layer. Since the magnetic material layer is integrally distributed in the wrapping material layer, so the cable body 100is magnetic and it is easy and simple to adjust a diameter of the coils by winding.
