Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfection devices for door handles are corrosive, harmful to skin, and damaging to metal door panels, with limited effectiveness in preventing the spread of infectious diseases due to direct contact and irritating odors.
Innovation Solution
A sterilization device with a main body, sanitizing lamp, and elastic fastening belt that securely attaches to door handles, using ultraviolet light for disinfection and a sensor to avoid harming humans, offering remote control and improved disinfection efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disinfectant spray is used for door handle disinfection, then disinfection coverage is improved, but corrosiveness and harm to skin increase
Solution Approach 1:
The patent replaces chemical disinfection (spray) with UV irradiation. The UV sterilization device uses ultraviolet light to kill bacteria and viruses on door handles, eliminating the need for corrosive chemical disinfectants while maintaining effective disinfection coverage.
Solution Approach 2:
The patent changes the disinfection method from chemical (liquid spray) to physical (UV radiation). This parameter change transforms the disinfection mechanism from chemical reaction to photobiological effect, resolving the contradiction between disinfection effectiveness and harmful chemical exposure.
2Reliability
If disinfectant spray is used for door handle disinfection, then disinfection capability is improved, but irritating odor harmful to humans increases
Solution Approach 1:
The patent substitutes chemical spray disinfection with UV irradiation. The sterilization device mounted on door handles emits UV light to disinfect surfaces without releasing irritating odors, maintaining disinfection capability while eliminating harmful airborne chemicals.
3Adaptability or versatility
If door panel is opened to install sprayer, then disinfection function is added, but original door panel is destroyed
Solution Approach 1:
The patent separates the disinfection function from the door panel structure. The UV sterilization device is installed as an independent component on the door handle, allowing the door panel to remain intact while adding disinfection functionality to the handle assembly.
Solution Approach 2:
The door handle assembly is transformed into a multi-functional component by integrating the UV sterilization device. The handle serves both its original function of opening doors and the new function of UV disinfection, eliminating the need to modify the door panel.
4Reliability
If metal door panel is opened for sprayer installation, then disinfection capability is improved, but door panel damage increases
Solution Approach 1:
The patent replaces chemical spray installation with UV device mounting. The sterilization device is attached to the door handle without requiring any opening or modification of the metal door panel, preserving panel integrity while providing disinfection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides effective disinfection without damaging door panels, reduces the risk of direct contact with harmful chemicals, and offers enhanced disinfection capabilities compared to traditional methods, while being easy to operate and detach.
Implementation Method 1
the sanitizing lamp emits light to illuminate the door handle to disinfect it
Implementation Method 2
the sensor element detects around the door handle, and the control element will control the sanitizing lamp to stop emitting light when someone approaching is sensed
Data Source
AI summary
A sterilization device for improving a disinfection effect includes: a main body, including a first surface, a second surface opposite to the first surface, and an accommodating hole, two sides of the main body respectively configured with a through hole, and the through holes in communication with the accommodating hole; a sanitizing lamp, configured on the second surface of the main body, the sanitizing lamp including a lighting element, sensor element, control element and power element; and a fixing member, passed through the through holes and accommodating hole of the main body. Taking a door handle as an example, the main body is passed through with the door handle through the accommodation hole, and the fixing member is then inserted through the through holes and accommodating hole, thereby fixing the main body on the door handle. Thus, the sanitizing lamp emits light to disinfect the door handle.
