Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional absorption air conditioning systems are used in motor vehicles, then cooling function is provided, but the system requires large volumes and has low absorption efficiency
Solution Approach 1:
The patent introduces water vapor plasma to change the physical-chemical parameters of the absorption process. The plasma treatment modifies the surface properties of the absorbent material, enhancing its absorption capacity and efficiency without requiring proportional increases in system volume.
Solution Approach 2:
The patent employs composite structures combining absorbent materials with plasma-treated surfaces. This composite approach creates a synergistic effect where the plasma-modified absorbent material achieves higher absorption efficiency per unit volume compared to conventional materials.
2Productivity
If absorption efficiency is increased through conventional means, then performance improves, but device complexity and production cost increase
Solution Approach 1:
The patent replaces complex mechanical compression and expansion mechanisms with a plasma-based absorption system. The water vapor plasma enables direct absorption enhancement without requiring additional mechanical components, valves, or complex control systems.
Solution Approach 2:
By changing the physical state and chemical properties of the absorbent material through plasma treatment, the system achieves improved performance through material property modification rather than adding complex mechanical or structural elements.
3Volume of stationary object
If system volume is reduced to lower cost, then manufacturing becomes cheaper, but absorption surface area is insufficient
Solution Approach 1:
The plasma treatment fundamentally changes the surface parameters of the absorbent material, increasing its effective absorption area at the molecular level. This allows a smaller physical volume to provide sufficient absorption surface area through enhanced surface properties.
Solution Approach 2:
The patent utilizes porous absorbent materials that have been plasma-treated. The porous structure provides high surface area to volume ratio, and the plasma treatment further enhances the surface properties, enabling compact design with adequate absorption capacity.

AI summary
The invention relates to a device that comprises a desorber (100), an absorber (400), a condenser (200) and an evaporator. The desorber (100) and the absorber (400) are filled with a mixture of at least two miscible substances comprising a coolant fluid and an absorbing fluid. The mixture is combined in the absorber (400) in which the coolant fluid is absorbed by the absorbing fluid. A means for increasing the pressure difference is provided between the desorber (100) and the condenser (200) so as to slightly increase the pressure at the condenser (200) and/or slightly decrease the pressure of the desorber (100) and thus improve the operation of the air-conditioning device. The invention also relates to automobiles, air-conditioning systems for automobiles, and absorption air-conditioning devices.
