Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvetemperature regulationVSAvoidcooling efficiency
Core Design Contradiction:
TemperatureVSProductivity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improvetemperature regulationVSAvoidcost
Core Design Contradiction:
TemperatureVSEase of manufacture

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

Inventive Principle:
Principle #25Self-service

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

Inventive Principle:
Principle #5Merging (Combining)
