Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If large amounts of water are sprayed at the blades for cooling and dust control, then cooling efficiency and dust suppression are improved, but water consumption increases and slurry generation increases
Solution Approach 1:
The patent applies pneumatic principles by using compressed air to atomize water into fine droplets through nozzles. This hydraulic-pneumatic combination creates a mist that covers a larger surface area and evaporates more efficiently, providing superior cooling with reduced water consumption compared to conventional spray methods
Solution Approach 2:
The patent changes the physical state and distribution parameters of water by atomizing it into fine droplets using compressed air. This parameter change from bulk liquid to atomized mist dramatically increases the surface area-to-volume ratio, enhancing heat transfer efficiency and reducing the total water quantity needed for effective blade cooling
2Object-generated harmful factors
If large amounts of water are used for dust control, then dust suppression is improved, but slurry volume increases and disposal complexity increases
Solution Approach 1:
The use of compressed air atomization creates a fine mist that effectively binds dust particles without generating excessive slurry. The pneumatic force disperses water droplets uniformly across the dust generation zone, achieving superior dust suppression with minimal water consumption and reduced slurry volume
Solution Approach 2:
The atomized water mist is delivered locally and precisely to the dust generation zones near the blades. This localized application ensures effective dust suppression at the source while minimizing overall water usage and preventing excessive slurry accumulation that would require complex disposal systems
3Temperature
If conventional spray systems are used, then cooling and dust control are provided, but water consumption is high and equipment complexity increases
Solution Approach 1:
The system integrates a compressed air source with simple atomizing nozzles to achieve effective blade cooling. This pneumatic-hydraulic approach replaces complex multi-component spray systems with a simpler configuration that uses air pressure to atomize water, reducing overall system complexity while maintaining or improving cooling performance
Solution Approach 2:
The atomizing nozzles utilize the kinetic energy of compressed air to automatically atomize water without requiring additional pumps, valves, or complex control mechanisms. The system is self-regulating through the pneumatic force, eliminating the need for complex water delivery infrastructure and reducing maintenance requirements
