Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat dissipation is achieved through conduction, convection, or phase transition, then heat can be transferred away from the heating element, but heat releasing efficiency is deteriorated due to limitations in these transfer manners
Solution Approach 1:
The patent replaces conventional heat transfer mechanisms (conduction, convection, phase transition) with thermal radiation mechanism. The pattern unit with pore part and cover part creates resonant cavities that enable efficient thermal radiation in the infrared wavelength band, substituting the mechanical heat transfer processes with electromagnetic radiation processes to achieve superior heat dissipation performance
Solution Approach 2:
The patent changes the physical parameters of the heat dissipation structure by creating a pattern unit with specific geometric parameters (pore part dimensions, cover part thickness, spacing between units). These parameter optimizations enable resonant enhancement of thermal radiation in the infrared band, transforming the heat dissipation process from conventional inefficient mechanisms to efficient radiative transfer
2Loss of energy
If a pattern unit with pore part and cover part is used to enhance thermal radiation, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The heat dissipation device is segmented into repeating pattern units, each comprising a pore part and a cover part. This segmentation allows the complex thermal radiation function to be distributed across multiple simple, identical modules, making the overall system manageable despite its advanced functionality. The pattern units can be arranged in arrays to achieve desired heat dissipation performance
Solution Approach 2:
The patent utilizes a porous structure (pore part) as a functional element rather than simply as void space. The pore part, in conjunction with the cover part, forms resonant cavities that enhance thermal radiation. This approach transforms what could be considered structural complexity into a functional advantage, where the porous architecture directly enables the improved heat dissipation mechanism
3Loss of energy
If ceramic materials with different absorptivities are used in the cover part, then emissivity and absorptivity are increased through optical tunneling and resonant effects, but manufacturing complexity increases
Solution Approach 1:
The cover part is designed with spatially varying properties - different ceramic materials with different absorptivities are placed in different regions or layers of the cover part. This local quality variation creates zones with different optical characteristics that work together to enhance overall emissivity and absorptivity through optical tunneling and resonant effects, while allowing each local region to be manufactured using standard techniques
Solution Approach 2:
The patent employs composite material structures in the cover part, combining different ceramic materials with complementary optical properties. This composite approach enables the structure to achieve enhanced emissivity and absorptivity across a broader wavelength range, particularly in the infrared band, by leveraging the synergistic effects of the different ceramic materials' optical characteristics
