Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sterilization methods using light sources for public transportation and multi-purpose facilities are inefficient due to the need for multiple light sources and increased sterilization time, leading to higher costs and reduced hygiene management effectiveness.
Innovation Solution
A sterilization apparatus with a movable and rotatable sterilization unit that includes multiple light sources and reflectors, allowing for adjustable light direction and reduced space occupation, enabling efficient sterilization of various target areas with fewer light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are installed to cover entire sterilization target area, then sterilization coverage is improved, but device complexity and cost increase
Solution Approach 1:
The sterilization unit is designed to be movable rather than fixed, allowing a single unit to dynamically reposition and rotate to cover multiple sterilization target areas. This dynamic positioning capability replaces the need for multiple fixed light sources, reducing device complexity while maintaining comprehensive coverage
Solution Approach 2:
A single sterilization unit is designed to serve multiple functions by covering various sterilization target areas through movement and rotation. This multi-functional design eliminates the need for separate light sources for different areas, reducing overall device complexity and cost
2Productivity
If multiple separate light sources are installed for multiple sterilization target areas, then sterilization efficiency is improved, but device complexity and space occupation increase
Solution Approach 1:
Multiple sterilization functions are merged into a single sterilization unit that can service multiple target areas. By combining what would traditionally require multiple separate light sources into one versatile unit, the system achieves high sterilization efficiency while reducing device complexity and space requirements
3Ease of operation
If sterilization unit is always positioned outside housing for easy access, then ease of operation is improved, but space occupation increases
Solution Approach 1:
The sterilization unit employs dynamic positioning, moving between an extended position outside the housing for easy access during operation and a retracted position inside the housing for compact storage. This dynamic positioning allows the system to alternate between ease of operation and minimal space occupation based on operational needs
