Ozone Shower Device Sanitization via Flow-Triggered Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower devices often harbor bacteria, mold, and viruses due to residual water in the spray head and shower enclosures, which existing technologies fail to effectively address.
Innovation Solution
A fluid delivery device for showers equipped with a water treatment assembly that includes an ozone generator, energy storage, and a controller to regulate ozone output, ensuring the spray head and shower enclosure are sanitized by directing ozonated water away from the user during treatment modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is left in the spray head and shower enclosure, then the shower device is ready for next use, but bacteria, mold, and viruses grow in the residual water
Solution Approach 1:
The system performs preliminary sanitation action by injecting ozone into the water supply before water flows through the spray head. This pre-treatment eliminates microorganisms in advance, allowing the spray head to retain water without subsequent contamination, thus resolving the contradiction between maintaining water for convenience and preventing microbial growth
Solution Approach 2:
Ozone serves as an intermediary substance that mediates between the water and the spray head environment. The ozone injectors introduce ozone gas into the water supply, which then distributes throughout the system, acting as a disinfecting intermediary that eliminates microorganisms while allowing water to remain in the system for convenient reuse
2Object-affected harmful factors
If ozone treatment is applied to sanitize the spray head, then bacteria and mold are eliminated, but user exposure to ozone must be minimized
Solution Approach 1:
The system applies local quality by concentrating ozone treatment in specific locations where microorganisms are present (water supply lines, spray head interior) while avoiding areas where users are exposed (shower enclosure atmosphere). The ozone injectors are positioned to treat water locally as it flows through the system, ensuring sanitation occurs where needed without creating harmful atmospheric ozone concentrations
Solution Approach 2:
The system rushes through the ozone treatment process quickly by injecting ozone into the flowing water supply during normal shower operation. The brief exposure time as water flows through the treated sections allows sufficient disinfection while minimizing overall ozone contact time, preventing accumulation of harmful ozone levels that could expose users
