Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If axial flow fans are used for duct circulation temperature control, then temperature regulation is achieved, but cooling efficiency is poor and additional cold air provision is required, leading to high costs
Solution Approach 1:
The invention divides the temperature control function into two independent modules: a cooling module with cooling fins and a heating module with heating fins. Each module operates independently to regulate temperature, eliminating the need for complex duct circulation systems and additional cold air provision, thereby improving cooling efficiency while maintaining temperature regulation capability
Solution Approach 2:
The invention replaces the mechanical duct circulation system with a direct thermal exchange system using semiconductor cooling sheets and heat sinks. This substitution eliminates the need for axial flow fans and ductwork, significantly improving cooling efficiency and reducing system complexity
2Temperature
If axial flow fans and duct circulation are used for temperature control, then temperature regulation is achieved, but additional cold air provision is required, resulting in high costs
Solution Approach 1:
The heating module serves a dual function: it not only provides heating when needed but also acts as a heat sink to dissipate excess heat from the cooling module. This self-service arrangement eliminates the need for additional cold air provision and external cooling systems, significantly reducing manufacturing costs while maintaining effective temperature regulation
Solution Approach 2:
The invention merges the heating and cooling functions into a single integrated temperature control apparatus. The heating fins and cooling fins are positioned adjacent to each other, allowing the heating module to serve as both a heat source and a heat dissipation path, thereby eliminating the need for separate cooling systems and reducing overall system cost
