Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple UVC ray emitting sources with fixed wavelengths are used, then the entire UVC spectrum can be covered, but the system complexity increases and sterilization efficiency is reduced due to lack of optimization for specific pathogens
Solution Approach 1:
The patent employs a single UVC emitting source combined with a flow circuit that dynamically models different wavelengths by varying fluid temperature and pressure. This dynamic approach allows the system to adapt to different pathogen vulnerabilities without requiring multiple fixed wavelength sources, thereby reducing device complexity while maintaining spectral coverage.
Solution Approach 2:
The invention changes physical parameters (temperature and pressure of the fluid in the flow circuit) to model different wavelengths of UVC radiation. By varying these parameters, a single source can effectively cover the entire UVC spectrum (200-280 nm), eliminating the need for multiple emitting sources and reducing system complexity.
2Reliability
If multiple UVC ray emitting sources with fixed wavelengths are used, then pathogen coverage is improved, but the sterilization efficiency decreases due to varying responses to different wavelengths
Solution Approach 1:
The system uses parameter changes in the flow circuit (temperature and pressure) to dynamically adjust the modeled wavelength, allowing optimization for specific pathogens. This enables higher sterilization efficiency by targeting the most vulnerable wavelengths for different pathogen types without requiring multiple fixed sources.
Solution Approach 2:
The flow circuit dynamically adjusts fluid conditions to model different wavelengths based on the specific pathogen being targeted. This dynamic adaptation allows the system to optimize sterilization efficiency for each pathogen type rather than using fixed wavelength sources that may not be optimally effective.
3Device complexity
If a single stationary UVC source is used, then device complexity is reduced, but the ability to target specific pathogen wavelengths is compromised
Solution Approach 1:
The flow circuit acts as an intermediary between the single UVC source and the pathogen. By modeling different wavelengths through fluid temperature and pressure variations, the flow circuit enables a single source to effectively target multiple pathogen vulnerabilities, providing adaptability without increasing source complexity.
Solution Approach 2:
The system uses parameter changes in the flow circuit to enable a single stationary source to effectively target different pathogen wavelengths. By varying fluid temperature and pressure, the single source can model the entire UVC spectrum, maintaining both simplicity and adaptability.
4Ease of operation
If fixed wavelength UVC sources are used, then the system is simpler to operate, but exposure time must be extended to ensure effective sterilization across all pathogen types
Solution Approach 1:
The flow circuit dynamically adjusts modeled wavelengths to match pathogen vulnerabilities, allowing for optimized exposure times. This dynamic adaptation enables shorter exposure times compared to fixed wavelength sources that must use conservative time settings to ensure effectiveness across all pathogen types.
Solution Approach 2:
By changing fluid parameters to model different wavelengths, the system can optimize exposure time for each specific pathogen type. This allows reduced exposure time compared to using fixed wavelength sources, while maintaining ease of operation through automated parameter adjustment.
