Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV light sanitizing systems for vehicles are large, bulky, and require fixed infrastructure, limiting their portability and efficiency in sanitizing internal cabin surfaces.
Innovation Solution
A galley cart equipped with UV light sources and a frame configured for use within a vehicle cabin, allowing portable sanitization by emitting UV light through transparent walls and compartments, with a power source for autonomy and a controller for operation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed stationary UV light infrastructure is used, then sanitizing effectiveness is improved, but portability and mobility deteriorate
Solution Approach 1:
The fixed stationary UV light infrastructure is segmented into a mobile galley cart that can be moved throughout the vehicle. The UV light sources are divided into multiple units mounted on the cart, allowing distributed sanitization coverage while maintaining portability. The cart itself is divided into functional sections including UV light mounting areas, transparent walls for light transmission, and storage compartments.
Solution Approach 2:
The system transitions from a static fixed infrastructure to a dynamic mobile platform. The galley cart is equipped with wheels for easy movement and can be positioned at different locations within the vehicle cabin. The UV light sources are mounted on movable cart structures, enabling dynamic deployment and repositioning to sanitize different areas as needed.
2Object-affected harmful factors
If UV light sources are enclosed in opaque housing, then safety is improved, but light transmission and sanitizing capability deteriorate
Solution Approach 1:
The cart structure employs different wall properties in different locations: transparent walls in areas requiring UV light transmission for sanitization, and opaque walls in areas where light blocking is needed for safety or non-sanitizing functions. This localized differentiation allows the same structure to simultaneously achieve both light transmission and safety requirements in different zones.
Solution Approach 2:
Transparent walls serve as intermediaries that allow UV light to pass through while still providing structural containment. These transparent barriers enable the UV light to reach surfaces for sanitization without requiring direct exposure of the light sources, thus maintaining safety while ensuring effective light transmission through the cart structure.
3Illumination intensity
If UV light sources are exposed externally, then light transmission is improved, but safety and protection of components deteriorate
Solution Approach 1:
Transparent walls act as intermediary structures that transmit UV light while providing physical protection and containment for the light sources. The light sources remain enclosed within the cart structure, protected from damage and accidental exposure, while the transparent walls allow the UV light to pass through effectively for sanitization purposes.
4Adaptability or versatility
If mobile galley cart is used, then portability is improved, but sanitizing coverage and effectiveness deteriorate
Solution Approach 1:
The UV light sanitization system is segmented into multiple light sources distributed across the mobile cart structure. This segmentation allows the cart to cover larger areas through multiple emission points simultaneously, compensating for the mobility limitation while maintaining comprehensive sanitizing coverage throughout the vehicle cabin.
Solution Approach 2:
The mobile galley cart is designed with multi-functionality: it serves as both a storage cart and a UV light sanitization platform. The transparent walls and structured design enable effective light transmission while the mobility allows it to be deployed throughout different areas of the vehicle, achieving both portability and comprehensive coverage.
