Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a liquid substance is fed to an evaporation surface with high flow rate, then evaporation efficiency is improved, but droplet formation occurs causing substance loss
Solution Approach 1:
The patent employs a porous distributor member with controlled pore size and distribution to regulate liquid flow across the evaporation surface. The porous structure allows the liquid to spread uniformly through capillary action, ensuring complete evaporation without droplet formation while maintaining high evaporation efficiency.
Solution Approach 2:
The patent controls the flow rate parameter by adjusting the liquid supply pressure and temperature to optimize the balance between evaporation efficiency and substance loss. By maintaining the liquid flow within specific parameter ranges, the system achieves efficient evaporation while preventing droplet formation.
2Manufacturing precision
If temperature control is applied to regulate flow rate through porous body, then flow precision is improved, but energy consumption increases
Solution Approach 1:
The patent utilizes the natural temperature dependence of liquid viscosity to self-regulate flow rate through the porous body. As temperature increases, viscosity decreases, allowing greater flow through the porous structure without additional energy input. This passive thermal regulation achieves precise flow control while minimizing energy consumption.
Solution Approach 2:
The patent exploits the physical parameter relationship between temperature and viscosity to control flow rate. By allowing temperature variations within a controlled range, the system achieves precise flow regulation through the porous body without requiring active heating or cooling mechanisms.
3Ease of operation
If removable assembly design is implemented, then ease of replacement is improved, but device complexity increases
Solution Approach 1:
The patent divides the diffusing apparatus into distinct modular components: a removable assembly containing the storage container and distributor member, and a fixed housing. This segmentation allows the consumable components to be easily replaced without affecting the permanent structure, simplifying maintenance and operation despite the additional interface requirements.
Solution Approach 2:
The removable assembly is designed as a universal module that can be easily attached and detached from the fixed housing. The standardized interface and modular design allow the same removable assembly to work with different housing configurations, reducing overall system complexity while improving ease of replacement.
