Innovation Solution
A collapsible UV disinfection unit with a reflective envelope that encloses objects to be disinfected, utilizing a UV source to ensure thorough disinfection by reflecting UV light to shadowed areas, and featuring a portable, easy-to-deploy design for efficient disinfection of various hospital items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning with chemical disinfectants is used, then ease of operation is maintained, but disinfection effectiveness is insufficient
Solution Approach 1:
The patent replaces manual mechanical cleaning with chemical disinfectants with an automated UV-C irradiation system. The UV disinfection unit uses ultraviolet light to eliminate pathogens on surfaces, substituting the mechanical wiping action and chemical application with a non-contact optical消毒 method that achieves superior disinfection effectiveness without manual intervention.
Solution Approach 2:
The UV disinfection unit is designed to operate autonomously without requiring manual operation. The system automatically irradiates surfaces with UV-C light when activated, eliminating the need for human operators to manually apply chemicals or wipe surfaces, thereby maintaining ease of operation while dramatically improving disinfection reliability.
2Reliability
If UV disinfection devices are deployed at equipment locations, then disinfection effectiveness improves, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent divides the hospital environment into discrete treatment zones, each equipped with a portable UV disinfection unit. Rather than deploying a single complex fixed system throughout the hospital, multiple independent UV units can be strategically placed at different equipment locations, simplifying individual device design while maintaining comprehensive coverage.
Solution Approach 2:
The UV disinfection units are designed to be mobile and repositionable rather than fixed installations. This dynamic deployment strategy allows the same simple portable device to serve multiple equipment locations throughout the hospital, reducing the need for complex fixed infrastructure at each location while maintaining disinfection effectiveness.
3Productivity
If traditional disinfection methods are used, then device complexity is low, but disinfection cycle time is excessive
Solution Approach 1:
The UV disinfection system provides continuous irradiation of surfaces without interruption, unlike manual cleaning methods that require stopping, repositioning, and resetting. The UV light continuously disinfects all exposed surfaces simultaneously, dramatically reducing the overall disinfection cycle time despite the added complexity of the UV lighting system.
Solution Approach 2:
The patent implements automated periodic disinfection cycles where UV units are activated at scheduled intervals to disinfect surfaces. This periodic operation allows for rapid turnover between disinfection cycles, reducing the effective cycle time compared to continuous manual cleaning processes, while the automation handles the complexity of timing and coordination.
