Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucets that provide ozone water suffer from high water temperature reducing ozone concentration, ineffective sterilization, and complex passage designs that further reduce ozone concentration and increase complexity.
Innovation Solution
A faucet design incorporating a control valve and detector to ensure ozone generation only with cold water flow, maintaining low water temperature for high ozone concentration, and independent passages for ozone and ordinary water, using a water mixing valve mechanism and ozone generator connected via a suction passage for efficient ozone addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If mixed water (hot and cold) is used for ozone generation, then water temperature is reduced, but ozone concentration decreases due to higher temperature
Solution Approach 1:
The water supply system is segmented into two independent passages: a first passage for cold water only (used during ozone generation) and a second passage for mixed water (used during ordinary water mode). This segmentation allows the system to select the appropriate water source based on operational mode, ensuring cold water is used when ozone is generated to maintain high ozone concentration.
2Reliability
If ozone is added to mixed water, then sterilization function is provided, but ozone concentration is reduced and sterilization effectiveness decreases
Solution Approach 1:
The system segments water flow paths into dedicated cold water passage for ozone generation and mixed water passage for ordinary use, preventing temperature-related ozone degradation.
Solution Approach 2:
The control unit receives feedback from the water temperature detector and automatically adjusts the valve states based on detected temperature. When warm water is detected (indicating mixed water flow), the system switches to the second passage, preventing ozone generation in warm water and maintaining sterilization effectiveness.
3Adaptability or versatility
If ozone water is mixed again with ordinary mixed water, then faucet can provide both functions, but passage complexity increases and ozone concentration further reduces
Solution Approach 1:
Instead of a single complex passage with mixing chambers, the system segments the flow path into two simple, independent passages. The first passage handles cold water and ozone generation, while the second passage handles mixed water for ordinary use. This segmentation simplifies the overall structure while maintaining dual functionality.
Solution Approach 2:
The system dynamically switches between two independent passages based on operational requirements. The control unit activates the appropriate passage configuration, allowing the faucet to adapt between ozone water mode and ordinary mixed water mode without requiring complex mixing mechanisms.
4Quantity of substance
If control system monitors water temperature and switches passages, then ozone concentration is maintained, but device complexity increases
Solution Approach 1:
A water temperature detector provides continuous feedback to the control unit, which automatically switches between passage configurations based on detected temperature. This feedback mechanism maintains high ozone concentration by preventing ozone generation in warm water, while the automation reduces operational complexity.
Solution Approach 2:
The control system performs automatic passage switching based on temperature detection without requiring user intervention. The system self-regulates the water flow path, maintaining optimal conditions for ozone generation while simplifying user operation.

AI summary
A faucet configured to discharge ozone water comprises a faucet body, a water mixing valve mechanism, a water processor, a control switch, a processor, a control valve, and a detector configured to detect whether water is flowing through the detector. The faucet body comprises a faucet outlet, and the water mixing valve mechanism comprises a cold water inlet connected to a cold water resource, a hot water inlet connected to a hot water resource, and a mixed water outlet. The water processor comprises a water processing passage and an ozone generator connected to the water processing passage. The control valve is disposed between the cold water resource and an inlet of the water processing passage, and an outlet of the water processing passage is connected to the faucet outlet. The detector is disposed between the mixed water outlet of the water mixing valve mechanism and the inlet of the water processing passage, and the processor is electrically connected to the control switch, the ozone generator, the detector, and the control valve to close the control valve and the ozone generator when the detector detects the water flowing through the detector.
