Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV-C light sanitizing devices are often large, bulky, and require wired connections or are too large for convenient portability, limiting their effectiveness and ease of use for personal hygiene.
Innovation Solution
A handheld UV-C sanitizing apparatus featuring a compact design with UV-C light emitting diodes (LEDs) positioned on both lower and upper internal surfaces of a main body, powered by a battery, and equipped with an on/off button and optional features like sensors and user identification systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional UV-C light sanitizing devices are used, then effective germicidal treatment is achieved, but the devices are large and bulky making them difficult to move and use portably
Solution Approach 1:
The device is divided into a main body housing and a removable hand grip assembly. The hand grip can be detached from the main body, allowing users to carry only the essential sanitizing component or separate storage components, thereby improving portability while maintaining germicidal effectiveness through the UV-C LED array in the hand grip
Solution Approach 2:
The patent transitions from traditional bulky UV-C devices to a compact handheld form factor by redistributing components across different spatial dimensions - placing the power source in the main body and the UV-C emitting components in the hand grip, creating a distributed architecture that reduces overall device bulk while maintaining functionality
2Ease of operation
If smaller portable UV-C devices are created, then portability is improved, but they require wired connections to electrical outlets or become too large to carry inconspicuously
Solution Approach 1:
The patent replaces the mechanical wired connection system with an electrical battery-powered system. The hand grip assembly contains a power source that provides electrical energy to the UV-C LEDs, eliminating the need for wired connections to electrical outlets and enabling truly portable, wireless operation
Solution Approach 2:
The main body housing serves multiple functions: it stores the power source, houses additional UV-C LED arrays for surface sanitizing, and can function as a standalone sanitizing device when the hand grip is attached or as a charging station for the hand grip, reducing the need for separate devices
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 apparatus effectively sanitizes skin, tissue, or surfaces by emitting UV-C light at a wavelength of 205-210 nm, capable of killing or reducing microorganisms without damaging human tissue, and offers improved portability and ease of use compared to traditional devices.
Implementation Method 1
a plurality of UV-C light emitting diodes (LEDs) configured to emit UV-C light
Implementation Method 2
UV-C light with a wavelength between approximately 100 to 290 nanometers (also referred to as 'UV-C light') can be used as a germicide to destroy the DNA in microorganisms
