Personal Mobility Device Handle-Grip UV Sterilization and Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal mobility devices, such as electric scooters and bikes, pose a risk of disease transmission due to direct contact with handle grips and helmets, and conventional cleaning methods do not sufficiently alleviate user anxiety about infection.
Innovation Solution
A personal mobility device equipped with UV generators, disinfectant sprays, fans, and automated control systems that clean and disinfect handle grips automatically when in use or after use, using ultraviolet light and disinfectants to sterilize and dry the grips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handle grips are exposed continuously for user access, then ease of operation is improved, but risk of disease transmission increases
Solution Approach 1:
The handle grip system is divided into multiple segments including movable handle grips that can be retracted into the frame, separating the exposed portion from the protected storage portion. This allows the handle grips to be hidden when not in use, reducing disease transmission risk while remaining accessible when needed.
Solution Approach 2:
The handle grips are designed to be dynamically movable between an exposed position for user operation and a retracted position inside the frame for protection. This dynamic positioning system allows the handle grips to adapt between accessibility and protection based on usage conditions.
2Device complexity
If manual cleaning of handle grips is performed, then device complexity is reduced, but cleaning effectiveness is insufficient to alleviate user anxiety
Solution Approach 1:
The system incorporates automated cleaning components including UV generators, disinfectant sprays, and fans that automatically clean and disinfect the handle grips without requiring manual intervention. This self-service cleaning system ensures consistent and effective disinfection, alleviating user anxiety about infection while maintaining reasonable device complexity.
Solution Approach 2:
The cleaning system performs preliminary disinfection actions before the user touches the handle grips. The UV generator and disinfectant spray are activated to sanitize the handle grips in advance, ensuring they are clean before contact, which addresses user anxiety about infection.
3Reliability
If UV generator and disinfectant spray systems are added, then disinfection effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple cleaning functions (UV generation, disinfectant spraying, air circulation via fans) are merged into an integrated cleaning system controlled by a single controller. This consolidation achieves comprehensive disinfection effectiveness while managing device complexity through unified control architecture.
Solution Approach 2:
The cleaning system components serve multiple functions: the UV generator provides both sterilization and drying, the disinfectant spray provides chemical disinfection, and the fans provide both drying and air circulation. This multi-functionality maximizes disinfection effectiveness while minimizing the number of separate components needed.
