Solution Overview
Problem
Conventional gas-dissolved liquid producing apparatuses do not effectively manage varying usage amounts, leading to surplus gas-dissolved water being discarded rather than reused.
Innovation Solution
A gas-dissolved liquid producing apparatus that includes a gas supply unit, a first liquid supply unit, a gas-dissolved liquid generator, a second liquid generator, a second liquid supply unit, a flow rate measuring unit, and a controller to control the supply of liquids based on measured flow rates, allowing for the circulation and reuse of gas-dissolved liquid, thereby adjusting production to match usage demands and preventing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the supply amount of gas-dissolved water is kept constant from the producing apparatus, then the production process is simple and stable, but surplus gas-dissolved water is wasted when usage amount decreases at the use point
Solution Approach 1:
The patent implements a feedback control system where the usage amount of gas-dissolved water at the use point is detected and this information is fed back to the producing apparatus. The producing apparatus adjusts its supply amount based on this feedback, ensuring that production matches actual usage demands and preventing waste of surplus gas-dissolved water.
Solution Approach 2:
The patent makes the supply amount of gas-dissolved water dynamic rather than constant. The producing apparatus can adjust its production rate in real-time based on varying usage conditions at the use point, allowing the system to adapt to changing demands and eliminate waste while maintaining operational simplicity.
2Reliability
If the supply amount of gas-dissolved water is increased to ensure sufficient supply, then usage demand is always met, but excessive production occurs when usage amount decreases
Solution Approach 1:
The feedback mechanism detects actual usage amounts and communicates this information to the producing apparatus. This allows the system to maintain reliable supply by producing exactly what is needed - no more, no less - thereby eliminating excessive production while ensuring usage demands are always met.
Solution Approach 2:
The patent changes the production parameter (supply amount) from a fixed high value to a variable value that adjusts according to actual usage conditions. This parameter adjustment ensures sufficient supply reliability while preventing overproduction and waste.
3Stability of the object's composition
If gas-dissolved water is continuously produced at a fixed rate, then production stability is maintained, but resource efficiency decreases when usage varies
Solution Approach 1:
The patent introduces dynamic adjustment capability to the production system. While maintaining operational stability through controlled adjustment, the system optimizes resource efficiency by producing gas-dissolved water at rates that match varying usage demands, eliminating waste associated with continuous fixed-rate production.
Solution Approach 2:
The production rate parameter is changed from a fixed constant to a variable that responds to usage conditions. This parameter change allows the system to maintain stability through smooth adjustments while significantly improving resource efficiency by eliminating overproduction during low-usage periods.

AI summary
A gas-dissolved liquid producing apparatus 1 includes a gas supply unit 2, a first liquid supply unit 3, a gas-dissolved liquid generator 4, a second liquid generator 20, a second liquid supply unit 21, a flow rate measuring unit 14, and a controller 23. The controller 23 controls the supply amount of the first liquid to be supplied to the gas-dissolved liquid generator 4 according to the flow rate of circulated gas-dissolved liquid measured by the flow rate measuring unit 14. The gas-dissolved liquid generator 4 dissolves gas supplied from the gas supply unit 2 in first liquid supplied from the first liquid supply unit 3 and second liquid supplied from the second liquid supply unit 21 to generate gas-dissolved liquid.
