Engineering Contradiction Analysis
1Temperature
If a large amount of filler components is applied to secure high thermal conductivity, then thermal conductivity is improved, but impact resistance deteriorates and the material becomes hard and brittle
Solution Approach 1:
The patent uses a composite material system consisting of a polymer matrix combined with ceramic fillers (such as aluminum oxide, aluminum nitride, or boron nitride) to achieve both high thermal conductivity and maintained mechanical properties. The composite structure allows the ceramic fillers to conduct heat while the polymer matrix provides flexibility and impact resistance, resolving the contradiction between thermal performance and mechanical strength.
2Temperature
If a large amount of filler components is applied to secure high thermal conductivity, then thermal conductivity is improved, but processability deteriorates
Solution Approach 1:
The patent optimizes the filler content parameter within a specific range (30-70 wt%) rather than using excessive amounts, and selects polymer matrices with appropriate viscosity and processing characteristics. This parameter optimization allows the material to achieve high thermal conductivity while maintaining good processability for molding and manufacturing operations.
