Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air flow is generated perpendicularly or parallel to the first surface of the Peltier element, then the cooling effect is achieved, but the heat absorption efficiency is insufficient
Solution Approach 1:
The patent changes the flow direction parameter by positioning the air outlet at a specific angle (10°-80°) relative to the first surface, optimizing the air flow angle to improve heat absorption efficiency while maintaining cooling effect
2Productivity
If the Peltier element cross-sectional area is increased to improve cooling capacity, then more heat can be dissipated, but the device occupies more space
Solution Approach 1:
The patent extends the heat dissipation approach from a two-dimensional surface to a three-dimensional structure by adding fins that protrude from the first surface, increasing the effective heat transfer area without proportionally increasing the device footprint
3Productivity
If the distance between the first heat transfer element and the second heat transfer element is reduced to improve heat transfer, then cooling efficiency increases, but energy losses increase
Solution Approach 1:
The patent applies insulation material selectively in specific regions (such as the sides and bottom of the housing) to prevent unwanted heat transfer, while maintaining optimal distance between heat transfer elements in the cooling path, thus reducing energy losses without compromising cooling efficiency
