Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single flow path with a bubble generating device is used, then the device structure is simple, but the bubble concentration cannot be adjusted
Solution Approach 1:
The liquid flow path is divided into multiple parallel flow paths (first flow path and second flow path), with bubble generating devices provided in each path. This segmentation allows independent control of bubble generation in each path, enabling adjustment of overall bubble concentration by controlling the flow rate distribution among the parallel paths.
2Adaptability or versatility
If multiple flow paths with bubble generating devices are used to adjust bubble concentration, then bubble concentration can be adjusted, but the device structure becomes complex
Solution Approach 1:
Multiple flow paths are merged into a common flow path downstream, allowing the liquid flows from different bubble generating devices to combine. This merging approach enables bubble concentration adjustment through flow rate control while avoiding the need for completely separate systems, thus limiting the increase in device complexity.
3Measurement precision
If flow rate ratio control is implemented to adjust bubble concentration, then bubble concentration can be precisely controlled, but the control system becomes more complex
Solution Approach 1:
The invention controls the flow rate parameter of liquid in each parallel flow path to adjust bubble concentration. By changing the flow rate parameter (e.g., using flow rate control valves or pumps), the bubble concentration can be precisely controlled since bubble generation is directly related to liquid flow rate through the bubble generating devices.
4Device complexity
If a common inlet is used for multiple flow paths, then the system structure is simplified, but the flow rate distribution control becomes more difficult
Solution Approach 1:
While using a common inlet for multiple flow paths to simplify structure, the invention introduces individual flow rate control mechanisms (such as control valves or flow controllers) in each parallel flow path. This allows local adjustment of flow rate in each path, enabling independent control of bubble generation while maintaining the structural simplicity of a common inlet.
