Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two fans are used for cooling and hot air ejection, then air circulation is achieved, but noise level increases
Solution Approach 1:
The patent extracts the hot air ejection function from the cooling system by using a separate exhaust channel. The cold air fan remains for cooling, while hot air is expelled through a dedicated duct, reducing the need for a second fan and lowering noise levels.
Solution Approach 2:
The air handling system is segmented into separate cold air intake and hot air exhaust paths. This segmentation allows independent optimization of each airflow path, enabling quieter operation by eliminating the need for multiple high-noise fans.
2Object-generated harmful factors
If ducting is used for hot air ejection, then hot air removal is achieved, but system complexity and installation inconvenience increase
Solution Approach 1:
The patent merges the hot air exhaust function with the existing mobile air conditioner unit by integrating a compact exhaust duct that connects directly to the device. This eliminates the need for separate external ducting systems while maintaining effective hot air removal.
Solution Approach 2:
The exhaust system utilizes vertical or angled exhaust paths that leverage the mobile nature of the air conditioner, allowing hot air to be expelled through windows or openings without requiring complex horizontal ducting installations.
3Temperature
If traditional air-to-air heat exchange is used, then cooling is achieved, but cooling efficiency is low
Solution Approach 1:
The patent introduces a water-based heat exchange system where water is circulated through radiators to remove heat from the air. This hydraulic approach provides more efficient heat transfer compared to traditional air-to-air heat exchange, significantly improving cooling efficiency.
Solution Approach 2:
Water serves as an intermediary heat transfer medium between the air conditioning system and the surrounding environment. The water circulation system with radiators acts as an efficient thermal bridge, enhancing the overall heat rejection capability and cooling performance.
