Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone-water supplying apparatuses require measures to prevent temperature rise and contamination due to circulation, and they continuously supply ozone water, leading to excess usage and waste.
Innovation Solution
A supply-liquid producing apparatus that mixes a first and second raw material, includes a pump unit to adjust flow rates, a gas-liquid separation tank for separating supply liquid and exhaust gas, and an exhaust control unit to maintain constant flow rate or pressure by adjusting exhaust gas discharge based on measured flow rates or pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ozone water is continuously supplied to meet demand, then supply reliability is improved, but excess ozone water is produced leading to waste and environmental contamination
Solution Approach 1:
The patent implements dynamic control of the ozone water supply system by continuously monitoring actual consumption at the use point and adjusting the supply amount in real-time. The control unit modifies operational parameters (such as pump speed or gas injection rate) based on feedback from flow meters and concentration sensors, enabling the system to adapt supply levels to actual demand rather than operating at fixed continuous supply mode
Solution Approach 2:
The system incorporates a feedback control mechanism where flow meters measure the actual ozone water consumption at the use point, and concentration sensors monitor ozone levels. This measurement data is fed back to the control unit, which adjusts the supply rate and concentration to match actual demand, thereby preventing both supply shortages and excessive production of waste ozone water
2Quantity of substance
If circulation type ozone-water supplying apparatus is used to recycle unused ozone water, then resource utilization is improved, but temperature rise and contamination occur due to circulation
Solution Approach 1:
The patent extracts the harmful effects (temperature rise and contamination) from the circulation system by implementing a different approach. Instead of circulating ozone water and dealing with its degradation, the system generates fresh ozone water on-demand and directs it to the use point, then discharges it after use. This eliminates the accumulation of heat and contaminants that would occur in a closed circulation loop
Solution Approach 2:
The system changes the operational parameters of ozone water supply from continuous high-concentration supply to variable supply with adjusted concentration levels. By controlling the ozone generation rate and water flow rate dynamically, the system optimizes the concentration and volume of ozone water produced, matching actual consumption patterns and reducing waste without requiring circulation
3Manufacturing precision
If ozone concentration and flow rate are increased to meet cleaning requirements, then cleaning effectiveness is improved, but the amount of ozone water needed increases leading to more waste
Solution Approach 1:
The patent applies local quality control by adjusting ozone concentration and flow rate according to the specific requirements at different use points and different time periods. The control unit varies the ozone generation parameters based on actual consumption data from flow meters and process requirements, ensuring that each location receives the precise amount and concentration of ozone water needed for effective cleaning without excessive supply
Solution Approach 2:
The system avoids excessive action by implementing partial supply mode where ozone water is supplied only to the extent actually needed at the use point. Rather than continuously supplying high concentrations to all locations, the control unit activates ozone generation and supply only when and where cleaning is actually being performed, based on real-time monitoring of consumption and process state
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables production and supply of ozone water in the needed amount at the point of use, reducing waste and the need for measures against temperature rise and contamination, while maintaining constant flow rate or pressure.
Implementation Method 1
a mixing unit that mixes a first raw material and a second raw material to produce a mixed liquid
Implementation Method 2
a gas-liquid separation tank unit that separates the mixed liquid produced by the mixing unit into a supply liquid to be supplied to a use point, and exhaust gas to be discharged from an exhaust port
Implementation Method 3
a pump unit that changes a flow rate of the first raw material to be supplied to the mixing unit
Implementation Method 4
an exhaust control unit that adjusts an exhaust amount of the exhaust gas to be discharged from the exhaust port by controlling the exhaust valve in response to the flow rate of the supply liquid measured by the first flow measuring unit such that the flow rate of the supply liquid to be supplied to the use point is kept at a constant flow rate
