Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If heat generating portions are arranged adjacently on an insulating substrate, then heat generation capacity is improved, but temperature distribution becomes uneven due to density differences
Solution Approach 1:
A heat equalizing portion is introduced as an intermediary element positioned between adjacent heat generating portions. This heat equalizing portion receives heat from multiple heat generating portions and redistributes it, acting as a mediator that balances the temperature distribution across the heater surface while maintaining high heat generation capacity.
Solution Approach 2:
The heater structure implements local quality differentiation by creating distinct functional zones: heat generating portions for heat production, heat equalizing portions for heat redistribution, and insulating substrates for thermal isolation. Each zone has optimized local properties to perform its specific function, with the heat equalizing portions having thermal conductivity and geometry designed specifically for heat distribution.
2Temperature
If heat equalizing portion is added between adjacent heat generating portions, then temperature distribution uniformity is improved, but device complexity increases
Solution Approach 1:
The heat equalizing portion is merged with the insulating substrate to form an integrated layered structure. The heat equalizing portion is positioned between the insulating substrate and the heat generating portions, combining thermal management functions within a unified structural framework rather than adding separate complex components.
Solution Approach 2:
The heat equalizing portion's dimensions and thermal properties are optimized through parameter adjustment. By controlling the thickness, area, and thermal conductivity of the heat equalizing portion, the system achieves effective heat distribution without requiring complex structural arrangements. The distance parameters between heat generating portions and heat equalizing portions are specifically designed to optimize heat transfer efficiency.
