Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional dehumidifiers use adsorbent materials to remove moisture from air, then dehumidification function is achieved, but excessive electric power is consumed during the desorption process due to liquid-to-gas phase change requirements
Solution Approach 1:
The invention utilizes the phase transition of the hygroscopic liquid from liquid to solid state through freezing, avoiding the need for liquid-to-gas phase change during desorption. The frozen hygroscopic liquid is directly replaced and disposed of, eliminating the energy-intensive evaporation process required in conventional dehumidifiers while maintaining effective moisture removal capability
Solution Approach 2:
The invention changes the operational parameters by using a liquid hygroscopic material instead of solid adsorbent, and by operating at temperatures below the freezing point of the liquid. This parameter change from ambient temperature adsorption to sub-freezing liquid phase operation enables direct replacement of frozen material without thermal desorption, significantly reducing energy consumption
2Reliability
If adsorbent powder is used to absorb moisture from air, then moisture adsorption capability is maintained, but the adsorbent requires energy-intensive heating for regeneration after absorbing water
Solution Approach 1:
The invention exploits the phase transition of the hygroscopic liquid to frozen state, where the frozen material is directly replaced without requiring energy-intensive heating for desorption. The new liquid hygroscopic material simply replaces the frozen material, eliminating the need for thermal regeneration processes
Solution Approach 2:
The invention extracts the moisture-absorbing function from a regenerable adsorbent system and replaces it with a disposable frozen liquid system. The hygroscopic liquid absorbs moisture effectively, and after freezing, the entire frozen mass is removed and replaced with fresh liquid, extracting the regeneration step entirely from the system

Function Achieved in This Case
The method and device effectively adsorb and desorb moisture at low power consumption, preserving efficiency even after repeated use by utilizing ultrasound to separate moisture from the hygroscopic liquid without significant liquid-to-gas phase changes.
Implementation Method 1
bringing a hygroscopic liquid containing a hygroscopic material into contact with a first mass of air so that the hygroscopic liquid absorbs moisture in the first mass of air
Implementation Method 2
