Door Handle Sanitizer With Track-Guided Full-Surface Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Door handles are frequently touched and can harbor pathogens like COVID-19, posing a risk of transmission, and existing disinfection methods may not effectively reach all surfaces of the handle.
Innovation Solution
An electromechanical door handle sanitizer with a flexible track structure and self-propelled disinfection mechanism that sprays a disinfecting solution onto all surfaces of the door handle, using a combination of quaternary ammonium and sodium 3,5-dichloro-2,4,6-trioxy,1,3,5-triazinan-1-ide solutions to effectively disinfect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing disinfection methods are used on door handles, then the disinfection process is simple, but the disinfection coverage is insufficient and cannot reach all surfaces of the handle
Solution Approach 1:
The patent employs a dynamic disinfection structure that moves along a track to reach different surfaces of the door handle. The movable component transitions between positions to spray disinfectant on front, back, and side surfaces, ensuring complete coverage while maintaining a relatively simple overall structure.
Solution Approach 2:
The disinfection structure utilizes multi-dimensional movement along the track, transitioning between different spatial positions and angles. This allows the single disinfection component to access all surfaces of the three-dimensional door handle structure, achieving comprehensive coverage without requiring multiple separate disinfection devices.
2Reliability
If a fixed disinfection structure is used, then the device structure is simple, but the disinfection structure cannot access all surfaces of the door handle
Solution Approach 1:
The patent introduces a dynamic element by making the disinfection structure movable along the track rather than fixed. This movement capability allows the disinfection component to reach front, back, and side surfaces of the door handle, achieving complete disinfection coverage while the track provides structural guidance.
Solution Approach 2:
The track structure serves as an intermediary element that mediates between the simple device architecture and the requirement for comprehensive surface access. The track provides a predefined path that enables the disinfection structure to systematically reach all surfaces without requiring complex positioning mechanisms.
3Productivity
If manual disinfection is used, then the device complexity is low, but the disinfection efficiency and thoroughness are insufficient
Solution Approach 1:
The patent implements an automated self-service disinfection system where the movable component autonomously travels along the track and dispenses disinfectant at appropriate positions. The system activates upon detecting door handle usage, eliminating the need for manual intervention and providing efficient, thorough disinfection without human labor.
Solution Approach 2:
The system incorporates feedback mechanisms through sensors that detect door handle usage, triggering the disinfection process automatically. This feedback loop ensures disinfection occurs at the appropriate time based on actual usage patterns, improving efficiency by avoiding unnecessary disinfection cycles while ensuring thoroughness when needed.
