Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal conduction or convection cooling technology is used to transfer waste heat from the inside of the enclosure to the outside, then heat dissipation can be achieved, but the cooling fins and fans occupy a significant portion of internal space within the enclosure
Solution Approach 1:
The patent replaces the mechanical cooling system (fans and cooling fins) with a radiative heat dissipation system. The aluminum oxide-boron nitride-fullerene composite material enables thermal radiation heat transfer, eliminating the need for mechanical convection components. This substitution resolves the contradiction by achieving effective heat dissipation without occupying significant internal space with mechanical cooling components.
Solution Approach 2:
The patent employs an aluminum oxide-boron nitride-fullerene composite material for the radiative heat dissipation unit. This composite material combines the high thermal conductivity of aluminum oxide, the thermal stability of boron nitride, and the radiative properties of fullerene, enabling efficient heat dissipation through thermal radiation without requiring large physical structures.
2Temperature
If thermal conduction or convection cooling technology is used with fans, then heat dissipation can be achieved, but the system consumes considerable power
Solution Approach 1:
The patent eliminates the need for electrically-powered fans by using radiative heat transfer. The aluminum oxide-boron nitride-fullerene composite material enables passive thermal radiation, which does not require external power input. This resolves the contradiction by achieving effective heat dissipation without the considerable power consumption associated with active fan-based convection systems.
3Temperature
If the number of cooling fins is increased to meet higher heat dissipation demand, then heat dissipation efficiency improves, but more space is required to set up these cooling fins and fans
Solution Approach 1:
The patent replaces the scaling-dependent mechanical cooling approach (more fins = more space) with a radiative heat transfer system. The aluminum oxide-boron nitride-fullerene composite material provides high heat dissipation efficiency through thermal radiation without requiring an increase in physical structure size. This resolves the contradiction by decoupling heat dissipation efficiency from physical space occupation.
