Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a distillation tank and heater are used for refrigerant recovery, then refrigerant purification is achieved, but device size increases and power consumption increases
Solution Approach 1:
The patent utilizes phase transition of the refrigerant between liquid and vapor states to achieve purification. The refrigerant evaporates from the heating element, rises to the condensation portion, condenses back to liquid, and returns to the reservoir. This natural phase transition cycle purifies the refrigerant by separating it from non-volatile contaminants without requiring a distillation tank or heater.
Solution Approach 2:
The system performs self-purification through the natural phase transition cycle. The heating element itself serves as the evaporation source, the condensation portion automatically condenses the vapor, and gravity causes the liquid refrigerant to return to the reservoir. No external power source or additional equipment is needed for purification, eliminating the need for large-scale distillation equipment.

3Productivity
If refrigerant is continuously circulated without condensation, then cooling efficiency is maintained, but impurity accumulation increases
Solution Approach 1:
The patent utilizes phase transition of the refrigerant between liquid and vapor states to achieve purification. The refrigerant evaporates from the heating element, rises to the condensation portion, condenses back to liquid, and returns to the reservoir. This natural phase transition cycle purifies the refrigerant by separating it from non-volatile contaminants without requiring a distillation tank or heater.
Solution Approach 2:
The system maintains continuous circulation of refrigerant through the heating element and condensation portion while simultaneously performing purification through phase transitions. The condensed liquid refrigerant continuously returns to the reservoir, ensuring both continuous cooling action and continuous purification, preventing impurity accumulation without interrupting the cooling cycle.
