Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high-speed swirling is used to generate fine bubbles, then the amount of fine bubbles increases, but the energy consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-mixing gas and liquid in a gas-liquid delivery unit before entering the fine bubble generating unit. This preliminary mixing ensures that gas and liquid are already combined in appropriate proportions, reducing the energy required for high-speed swirling to generate fine bubbles, as the mixing process has already been partially completed.
Solution Approach 2:
The patent replaces part of the mechanical high-speed swirling system with a pressure-based fine bubble generating mechanism. By using pressure to generate fine bubbles instead of relying solely on mechanical swirling, the energy consumption is reduced while still achieving the desired amount of fine bubbles in the liquid.
2Adaptability or versatility
If multiple processing devices process medium liquid separately, then each device can be optimized for specific function, but the system complexity increases
Solution Approach 1:
The patent merges multiple processing functions into a single integrated fine bubble generating apparatus. The gas-liquid delivery unit and fine bubble generating unit work together as one system, combining gas mixing, liquid delivery, and fine bubble generation functions, thereby reducing system complexity while maintaining versatile processing capabilities.
Solution Approach 2:
The fine bubble generating apparatus is designed with multi-functionality, where the same device can handle different gas-liquid mixing requirements and generate fine bubbles for various applications. The universal design allows the system to perform multiple processing functions without requiring separate specialized devices for each function.
3Stability of the object's composition
If gas and liquid are mixed thoroughly before fine bubble generation, then the homogeneity of mixed liquid improves, but the time required for mixing increases
Solution Approach 1:
The gas-liquid delivery unit performs preliminary mixing of gas and liquid before the mixed flow enters the fine bubble generating unit. This preliminary action ensures that gas and liquid are already well-mixed and distributed, so that when high-speed swirling occurs in the fine bubble generating unit, the homogeneity is quickly achieved without requiring extended mixing time.
Solution Approach 2:
The patent transitions from gradual mixing in one dimension to instantaneous mixing in another dimension by using high-speed swirling and physical collisions. Instead of relying on prolonged contact time for mixing, the system uses the kinetic energy of swirling flow to rapidly homogenize the gas-liquid mixture, effectively changing the mixing approach from time-based to energy-based.
