Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a refrigeration cycle is used to remove moisture from air, then dehumidification is achieved, but the temperature of the discharged air increases causing user discomfort
Solution Approach 1:
The patent divides the air flow into two separate streams: a main flow that passes through the dehumidification module for moisture removal, and a sub-flow that passes through the heat exchanger for cooling. This segmentation allows independent optimization of each stream's function, enabling moisture removal without necessarily heating the final discharged air.
Solution Approach 2:
The patent introduces a heat exchanger as an intermediary component that cools the main flow after dehumidification. This mediator transfers heat from the warmed dehumidified air to the sub-flow, thereby reducing the temperature of the air before discharge while maintaining the dehumidification effect.
2Quantity of substance
If a refrigeration cycle is used for dehumidification, then moisture can be removed, but time is required for stabilization of the refrigeration cycle
Solution Approach 1:
The patent replaces the complex refrigeration cycle (involving compressors, condensers, expansion valves, and evaporators) with a simpler membrane-based dehumidification system. The membrane module physically separates moisture from air through selective permeation, eliminating the need for refrigerant circulation and cycle stabilization, thereby enabling immediate dehumidification operation.
3Productivity
If perpendicular suction flows are used to improve moisture separation, then dehumidification efficiency increases, but device complexity increases due to additional components
Solution Approach 1:
The patent combines the dehumidification module and heat exchanger into a single integrated housing structure. The perpendicular flows are achieved within this unified structure by strategically positioning the dehumidification module and heat exchanger to receive air from different directions, merging multiple functions into one compact unit rather than separate components.
