Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single heat dissipation layer is used, then the device structure is simple, but the heat dissipation performance is insufficient
Solution Approach 1:
The heat dissipation system is divided into two separate layers: a first heat dissipation layer with first nanoparticles and a second heat dissipation layer with second nanoparticles. Each layer has different thickness and nanoparticle concentration, allowing optimized heat dissipation at different depths while managing device complexity through modular design.
2Temperature
If uniform nanoparticle concentration is used throughout the heat dissipation layer, then the manufacturing process is simple, but the heat dissipation efficiency is reduced
Solution Approach 1:
The first heat dissipation layer has a first nanoparticle concentration and the second heat dissipation layer has a second nanoparticle concentration, with the first concentration being different from the second concentration. This local variation in nanoparticle distribution optimizes heat dissipation efficiency at different depths of the device.
3Temperature
If thicker heat dissipation layer is used, then the heat dissipation performance is improved, but the device thickness increases
Solution Approach 1:
The patent optimizes the thickness of each heat dissipation layer and the concentration of nanoparticles to achieve effective heat dissipation while minimizing overall device thickness. By adjusting these parameters, the system balances heat dissipation performance with compact device design.

AI summary
A display device includes a display panel including a base layer, a first heat dissipation member disposed on a first surface of the base layer, and a second heat dissipation member disposed on a first surface of the first heat dissipation member. The first heat dissipation member includes a first polymer resin and first heat dissipation nano-particles dispersed in the first polymer resin, and the second heat dissipation member includes a second polymer resin and second heat dissipation nano-particles dispersed in the second polymer resin. The weight of the first heat dissipation nano-particles in the first heat dissipation member may be different from the weight of the second heat dissipation nano-particles in the second heat dissipation member.
