Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If discrete magnet blocks or rings are used in conventional magnetic data cables, then magnetic attraction strength is sufficient, but the cable diameter increases and flexibility is reduced
Solution Approach 1:
The patent applies this principle by using a thin magnetic powder coating layer (thickness of a few micrometers to sub-millimeter) instead of discrete magnet blocks or thick magnetic rings. This thin film approach provides sufficient magnetic attraction while minimizing cable diameter increase and maintaining flexibility.
Solution Approach 2:
The patent applies this principle by creating a composite material structure where magnetic powder is dispersed and coated on the cable surface. This composite approach combines the magnetic properties of magnetic powder with the flexibility and structural integrity of the cable material, achieving both strong magnetic attraction and thin profile.
2Force
If discrete magnet blocks or rings are used in conventional magnetic data cables, then magnetic attraction is achieved, but the cable structure becomes complex and weight increases
Solution Approach 1:
The patent applies this principle by merging the magnetic function directly into the cable structure through surface coating, eliminating the need for separate discrete magnet blocks or rings. This integration simplifies the overall cable structure while maintaining magnetic attraction capability.
Solution Approach 2:
The thin magnetic powder coating serves as a flexible shell that provides magnetic attraction without adding structural complexity. This thin film approach replaces complex discrete magnetic components with a simple, integrated coating layer.
3Force
If thick magnetic rings are used to ensure strength, then magnetic attraction is sufficient, but the cable diameter increases by at least 3 mm
Solution Approach 1:
The patent directly addresses this contradiction by using a thin magnetic powder coating instead of thick magnetic rings. The coating thickness is reduced from millimeters to micrometers or sub-millimeter scale, providing sufficient magnetic attraction while minimizing diameter increase.
Solution Approach 2:
The patent applies parameter changes by transitioning from thick magnetic rings (millimeter-scale thickness) to thin magnetic powder coatings (micrometer to sub-millimeter thickness). This parameter change in thickness while maintaining magnetic functionality reduces cable diameter significantly.

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 100 is magnetic and it is easy and simple to adjust a diameter of the coils by winding.
