Solution Overview
Problem
Conventional space purification devices face challenges in adjusting the amount of purification component released into indoor spaces, as they either fail to vaporize sufficient purification component during low humidification periods or release excessive amounts during high humidification periods, leading to inefficient air purification.
Innovation Solution
A space purification system that includes a hypochlorous acid water generator, a water supplier, a water level sensor, and a control unit that controls the supply and drainage of mixed hypochlorous acid water and water in a mixing tank, allowing for adjustable release of hypochlorous acid based on humidity levels by varying the frequency of hypochlorous acid water supply and water addition, and draining excess water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water containing purification component is continuously supplied to maintain purification component release, then purification effect is maintained, but purification component concentration becomes uncontrollable and excessive release occurs during high humidification periods
Solution Approach 1:
The system implements periodic supply of hypochlorous acid water at predetermined time intervals rather than continuous supply. The control unit executes first control to supply hypochlorous acid water periodically, which allows the purification component concentration to be regulated and prevents excessive release during high humidification periods while maintaining effective purification through regular replenishment
Solution Approach 2:
The system uses a water level sensor to detect the water level in the mixing tank and feeds this information back to the control unit. The control unit executes second control to supply water based on this feedback, and executes third control to drain mixed water based on integrated humidification amount, creating a closed-loop control system that maintains optimal water levels and purification component concentrations
2Productivity
If water supply is increased to maintain water level during high humidification periods, then vaporization is improved, but purification component concentration is diluted and release efficiency decreases
Solution Approach 1:
The system supplies hypochlorous acid water periodically at predetermined time intervals rather than continuously. This periodic supply allows the concentration to be maintained by replenishing purification components at regular intervals, preventing dilution that would occur with continuous water supply while still maintaining adequate water levels for vaporization
Solution Approach 2:
The system changes the supply parameters by executing first control to supply hypochlorous acid water at predetermined time intervals and second control to supply water based on water level sensor feedback. This dynamic adjustment of supply parameters allows the system to maintain optimal concentration levels while ensuring sufficient water for vaporization during high humidification periods
3Quantity of substance
If hypochlorous acid water supply frequency is increased to maintain purification component concentration, then purification component availability is improved, but water level in mixing tank increases and causes overflow or excessive drainage
Solution Approach 1:
The system supplies hypochlorous acid water periodically at predetermined time intervals rather than continuously or frequently. This periodic supply pattern maintains purification component concentration by replenishing at regular intervals while allowing water level to stabilize between supply cycles, preventing both overflow and excessive drainage
Solution Approach 2:
The water level sensor continuously monitors the water level in the mixing tank and provides feedback to the control unit. The control unit adjusts water supply and drainage operations based on this feedback, executing second control to supply water based on water level information and third control to drain water based on integrated humidification amount, thereby maintaining optimal water levels
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 precise control over the amount of hypochlorous acid released into the air, ensuring effective air purification by maintaining optimal hypochlorous acid concentration regardless of humidity levels, thereby addressing the inefficiencies of conventional systems.
Implementation Method 1
a humidifying purifier that micronizes and releases, into air, mixed water of the hypochlorous acid water and the water stored in the mixing tank
Implementation Method 2
water containing the micronized purification component is easily vaporized, and therefore a large amount of purification component is released into the indoor space
