Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same circulation route is used for both gas dissolution and fine bubble generation, then the apparatus structure is simplified, but the production efficiency of ultrafine bubbles is reduced due to incompatible circulation conditions
Solution Approach 1:
The circulation route is divided into two separate routes: a first circulation route for gas dissolution and a second circulation route for ultrafine bubble generation. This segmentation allows each route to be optimized independently for its specific function, resolving the contradiction between simplified structure and production efficiency.
Solution Approach 2:
The system dynamically switches between different circulation modes. The circulation controlling unit can select which circulation route to activate based on the operational phase (dissolution or bubble generation), allowing the apparatus to adapt its configuration to maximize efficiency at each stage.
2Ease of operation
If the circulation conditions are kept the same for both dissolution and bubble generation steps, then the control system is simplified, but the quality and concentration of ultrafine bubbles are reduced
Solution Approach 1:
Different circulation conditions are applied to different parts of the system depending on the operational phase. During dissolution, conditions are optimized for gas absorption; during bubble generation, conditions are optimized for ultrafine bubble formation. This local optimization of conditions resolves the contradiction between control simplicity and bubble quality.
Solution Approach 2:
The circulation controlling unit changes key parameters (flow rate, pressure, circulation route selection) based on the operational phase. This dynamic parameter adjustment allows the system to achieve high bubble concentration and quality while maintaining automated control that doesn't overly complicate operation.
3Device complexity
If the circulation route is shared between dissolution and bubble generation units, then the system configuration is simplified, but the longevity and stability of ultrafine bubbles are reduced
Solution Approach 1:
The circulation system is segmented into separate routes that prevent contamination of the ultrafine bubble generation process by dissolution operations. This segmentation protects the bubble stability by ensuring they are generated and maintained under dedicated, optimized conditions rather than being subjected to the varying conditions of a shared route.

AI summary
In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus includes a gas dissolving unit that dissolves a predetermined gas into a liquid, and a UFB generating unit that generates ultrafine bubbles in the liquid in which the predetermined gas is dissolved. A CPU performs control under a first condition in a case of causing the gas dissolving unit to operate in a circulation route passing through the dissolving unit. The CPU performs control under a second condition different from the first condition in a case of causing the UFB generating unit to operate in a circulation route passing through the UFB generating unit.
