Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a water tank with water pump is used for temperature regulation, then the fan can cool ambient air through evaporation, but the temperature regulation efficiency is insufficient
Solution Approach 1:
The patent employs a water curtain plate with porous structure that allows water to permeate and form a thin film. This porous configuration dramatically increases the evaporation surface area compared to traditional water tank designs, enabling more efficient heat absorption through evaporation and thus improving temperature regulation efficiency
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to vapor through evaporation on the water curtain plate. This phase change process absorbs latent heat from the ambient air, providing effective cooling. The continuous supply of water to maintain this phase transition enhances the temperature regulation efficiency
2Area of stationary object
If metal honeycomb paper is used for the evaporation unit, then the specific surface area is increased for better evaporation, but the manufacturing complexity increases
Solution Approach 1:
The patent uses metal honeycomb paper with a porous three-dimensional structure that provides an extremely high specific surface area within a compact volume. This porous structure allows water to distribute uniformly across the entire surface, maximizing evaporation efficiency while the modular honeycomb design facilitates standardized manufacturing
Solution Approach 2:
The patent combines metal honeycomb paper with water-resistant coating or composite structures to enhance both the evaporative performance and manufacturability. The composite material approach maintains the high surface area advantage while improving durability and ease of integration into the fan system
3Measurement precision
If vortex refrigeration assembly is added to feed cold air flow, then the temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a vortex refrigeration assembly that acts as an intermediary cooling system. This assembly generates cold air flow through vortex-induced cooling effects and feeds it into the air flow passage, providing precise temperature control. The vortex mechanism serves as a mediator between the cooling source and the ambient air, enabling fine-tuned temperature regulation
Solution Approach 2:
The patent utilizes pneumatic principles through the vortex refrigeration assembly that manipulates air flow dynamics. By creating vortex patterns in the air flow, the system enhances heat transfer efficiency and achieves precise temperature control through fluid dynamic effects, adding functionality through pneumatic mechanisms
