Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrolytic pure water ozone generator is used to generate ozone gas and mix with tap water, then ozone water can be produced for sterilization, but the system becomes complex and costly
Solution Approach 1:
The patent extracts the water electrolysis function from a separate pure water ozone generator and integrates it directly into the tap water pipeline system. The electrolytic cell is installed inline, allowing direct electrolysis of tap water to generate ozone bubbles that dissolve into the flowing water, eliminating the need for separate ozone generation and mixing equipment.
Solution Approach 2:
The patent merges the ozone generation function with the existing water pipeline system by installing the electrolytic cell directly in the pipeline. This integration combines water flow, electrolysis, and ozone dissolution into a single unified system, reducing overall system complexity while maintaining sterilization effectiveness.
2Reliability
If an electrolytic pure water ozone generator is used to generate ozone water, then sterilization can be achieved, but the cost increases
Solution Approach 1:
The system utilizes the existing tap water infrastructure and electrical power supply to generate ozone water in-place. The electrolytic cell uses standard electrical components and the water already present in the pipeline, eliminating the need for expensive specialized equipment, pure water storage tanks, and complex ozone mixing apparatus.
Solution Approach 2:
The patent employs a simple electrolytic cell with replaceable electrodes that can be easily manufactured at low cost. The cell design allows for inexpensive replacement of consumable components, reducing overall system cost while maintaining effective sterilization through continuous ozone generation.
3Productivity
If lead dioxide catalysts are used in the ozone generator, then ozone generation efficiency is improved, but environmental pollution and catalyst degradation occur
Solution Approach 1:
The patent changes the material parameter of the electrode from lead dioxide to tin dioxide coating on titanium substrate. This material substitution maintains the catalytic function for ozone generation while eliminating the environmental pollution and degradation issues associated with lead-based catalysts. The tin dioxide coating provides stable, non-toxic catalytic activity.
Solution Approach 2:
The patent uses a composite structure of titanium substrate with tin dioxide coating. The titanium provides mechanical strength and corrosion resistance, while the tin dioxide layer provides catalytic activity for ozone generation. This composite material approach achieves high ozone generation efficiency without the environmental harm of lead dioxide.
4Reliability
If a complex ozone generation system is installed, then sterilization capability is achieved, but maintenance difficulty increases
Solution Approach 1:
The electrolytic cell is designed as a segmented, modular unit that can be easily removed and replaced. The cell separates the electrolysis chamber from the pipeline, allowing maintenance personnel to access and replace the electrolytic component without shutting down or modifying the rest of the water system, significantly easing maintenance requirements.
