Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UV light sterilization system is used to sanitize surfaces within aircraft, then the sanitizing effectiveness is improved, but the system becomes large, bulky, and requires fixed infrastructure
Solution Approach 1:
The system is divided into separate functional modules: a portable UV wand assembly for sanitization and a separate power/cooling station. This segmentation allows the sanitizing function to be mobile and flexible while the bulky power components remain stationary, resolving the contradiction between portability and effectiveness.
Solution Approach 2:
The UV lamp and wand assembly are extracted from the fixed infrastructure and made portable. The wand can be removed and used independently in various locations within the aircraft, eliminating the need for fixed mounting while maintaining sanitizing effectiveness.
2Ease of operation
If a portable UV lamp system is used for sanitization, then the mobility and compactness are improved, but the cooling requirement for the UV lamp becomes more challenging
Solution Approach 1:
A cooling fan is introduced as an intermediary component to remove heat from the UV lamp. The fan creates air flow that passes over the UV lamp, effectively transferring heat away from the lamp while allowing the system to remain portable and compact.
3Reliability
If UV light is emitted to disinfect surfaces, then the disinfection capability is improved, but the system requires precise wavelength control for effectiveness
Solution Approach 1:
The system uses UV lamps with specific wavelength characteristics (200-280 nm range) that are inherently suited for disinfection. By selecting lamps with appropriate wavelength parameters and controlling operating conditions, the system achieves effective disinfection without requiring complex precision control mechanisms.

AI summary
A portable sanitizing method includes moving a cover of a case assembly between an open position that exposes a storage chamber and a closed position; storing a wand assembly including a sanitizing head having an ultraviolet (UV) lamp in the storage chamber when not in use; and removing the wand assembly from the storage chamber to disinfect one or more components with UV light emitted by the UV lamp.
