Engineering Contradiction Analysis
1Temperature
If conventional paint layers are used on conductive wires, then insulation is provided, but thermal conductivity remains low (2 to 10 W/(m·K) is achieved only with special materials)
Solution Approach 1:
The patent applies composite materials by combining graphene with metal coatings (aluminum, silver, copper) to create paint layers with enhanced thermal conductivity. The composite structure of graphene-metal coatings provides both insulation and improved heat dissipation, achieving thermal conductivity of 2 to 10 W/(m·K) while maintaining electrical insulation properties.
Solution Approach 2:
The patent changes the thermal conductivity parameter of the paint layer by incorporating specific materials and controlling their thickness. By adjusting the composition and thickness of graphene-based coatings with metal layers, the thermal conductivity is optimized to balance insulation requirements with heat dissipation needs.
2Reliability
If multi-layer winding arrangement is used in coils, then insulation between layers is improved, but heat dissipation is hindered
Solution Approach 1:
The patent uses composite paint layers with graphene and metal coatings on conductive wires to improve thermal conductivity. This allows multi-layer winding arrangements to maintain both insulation and heat dissipation, as the composite material provides thermal pathways through the insulating layers.
Solution Approach 2:
The patent applies local quality by creating paint layers with specific thermal conductivity properties at different locations and orientations. The graphene-metal composite structure provides enhanced thermal conduction in specific directions while maintaining insulation in others, enabling effective heat dissipation in multi-layer windings.

Solution Approach 1:
The patent changes the thermal conductivity parameter of conductive wires through graphene-based coatings, enabling miniaturized components to dissipate heat more effectively. This allows reduced device size and weight while maintaining acceptable operating temperatures through improved thermal management at the material level.
