Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wires for everyday use are difficult to store and are easily damaged due to wear, compression, or pulling, leading to disordered arrangements that can cause safety hazards and reduce their service life.
Innovation Solution
A wire cable with a magnetic attraction effect is designed, featuring a braid layer, a protective layer, and a magnetic attraction layer composed of specific raw materials, including thermoplastic elastomer, compatilizer, stabilizer, lubricant, phenolic resin, and a magnetic attraction filler, which allows the wires to be automatically rolled into a bundle, reducing tangling and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wires are used without magnetic attraction layer, then the structure is simple and manufacturing is easy, but the wires are easily scattered and disordered during use and storage
Solution Approach 1:
The patent applies composite materials by incorporating magnetic attraction filler (such as iron oxide or magnetite particles) into the cable insulation material, creating a composite polymer matrix that combines the electrical insulation properties of the base material with the magnetic attraction properties of the filler particles. This allows the cable to be actively attracted to magnetic storage devices, solving the wire management problem without requiring separate magnetic components.
Solution Approach 2:
The patent replaces mechanical wire management systems (such as clips, ties, or manual organization) with a magnetic field-based system. The magnetic attraction layer enables passive, automatic wire organization through magnetic interaction with storage devices, eliminating the need for additional mechanical management components and simplifying the overall system.
2Volume of stationary object
If wires are stacked or stored without organization, then storage space requirement is reduced, but the wires suffer from wear, compression and pulling damage
Solution Approach 1:
The patent implements self-service by enabling the cable to automatically organize itself through magnetic attraction to designated storage locations on magnetic storage devices. The cable autonomously seeks out and attaches to the magnetic surface, eliminating the need for external intervention or additional storage infrastructure, while simultaneously protecting itself from damage during storage.
Solution Approach 2:
The patent provides beforehand cushioning by designing a controlled storage mechanism where the cable is attracted to a dedicated magnetic surface on the storage device. This predetermined storage location prevents the cable from being crushed under furniture or subjected to random compression, as it is magnetically held in a protected position before any external forces are applied.
3Reliability
If magnetic attraction filler is added to the cable insulation, then magnetic attraction effect is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the magnetic attraction function with the cable insulation material itself, rather than adding separate magnetic components. The magnetic filler particles are incorporated directly into the insulation compound during the extrusion or molding process, combining two functions (insulation and magnetic attraction) into a single integrated material system, thereby simplifying the overall manufacturing process.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the extrusion or molding process parameters to accommodate the magnetic filler particles. The manufacturing process is modified to include mixing the magnetic filler with the polymer matrix and adjusting processing conditions (temperature, pressure, mixing time) to ensure uniform distribution and proper bonding, without fundamentally changing the manufacturing methodology.
4Volume of stationary object
If wires are left disordered on table or ground, then storage space is saved, but safety hazards such as short circuit and poor current transmission occur
Solution Approach 1:
The patent introduces a magnetic field as an intermediary force that mediates between the cable and the storage device. This magnetic intermediary enables controlled interaction, allowing the cable to be reliably stored on magnetic surfaces of storage devices, preventing it from being left in hazardous positions while maintaining flexible, space-efficient organization.

Function Achieved in This Case
The magnetic attraction layer ensures wires remain orderly, enhancing cleanliness and safety, while the protective layer improves durability and longevity by preventing wear and damage, thus prolonging the service life of the wires.
Implementation Method 1
the magnetic attraction filler is a key component for realizing a magnetic attraction function in the magnetic attraction layer and can produce an enough magnetic force, so that the wires can be mutually adsorbed and arranged into a bundle

AI summary
The present application relates to a wire cable with a magnetic attraction effect and a preparation method thereof. The wire cable sequentially includes a braid layer, a protective layer and a magnetic attraction layer from exterior to interior. The magnetic attraction layer is prepared from the following raw materials in percentage by weight: 40-50% of a thermoplastic elastomer, 2-3% of a compatilizer, 3-6% of a stabilizer, 5-10% of a lubricant, 10-15% of a phenolic resin and a balance of a magnetic attraction filler; and the protective layer is prepared from the following raw materials in percentage by weight: 80-90% of the thermoplastic elastomer, 1-2% of the compatilizer, 0.5-1% of a flexibilizer and a balance of the phenolic resin. By means of the magnetic attraction layer, wires can be adsorbed easily and arranged automatically, thereby avoiding a phenomenon that the traditional wires are disordered during use and storage.
