UV LED Sterilization Cover for Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sterilization apparatuses for portable terminals are not portable and cannot effectively sterilize devices while they are in motion, as they require a separate setup and cannot be used with the terminal carried on.
Innovation Solution
A sterilization apparatus integrated into a casing or cover attached to the portable terminal, featuring a UV LED for radiation and a reflection part that can be deployed to cover the screen, powered by a Near Field Communication (NFC) antenna, allowing for on-the-go sterilization without additional power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sterilization apparatus is used for portable terminals, then sterilization function is provided, but portability is reduced because it needs to be additionally provided apart from the portable terminal
Solution Approach 1:
The sterilization apparatus is merged with the portable terminal by integrating the UV LED sterilization module into the terminal's housing or cover. The control unit is combined with the terminal's existing control system, and the power supply unit shares the terminal's battery, creating a unified integrated device that maintains sterilization functionality while improving portability.
Solution Approach 2:
The portable terminal is designed to serve multiple functions: it acts as both a communication device and a sterilization apparatus. The UV LED module can be activated through the terminal's existing interface (touch screen or buttons), allowing the terminal to universally perform both its primary communication role and the additional sterilization function without requiring separate dedicated equipment.
2Reliability
If a conventional sterilization apparatus is used for portable terminals, then sterilization function is provided, but it cannot sterilize a portable terminal in motion because it is used with the terminal carried on in an office or at home
Solution Approach 1:
The sterilization apparatus is designed with dynamic activation capability, allowing it to be triggered on-demand through the terminal's existing interface (touch screen or buttons) rather than requiring a fixed setup. The UV LED module can be activated at any time and location, enabling sterilization in motion or in various environments beyond traditional office or home settings.
Solution Approach 2:
The integrated control unit allows the terminal itself to initiate and control the sterilization process through its existing user interface, eliminating the need for external control equipment or fixed installation. The terminal serves its own sterilization needs autonomously, enhancing adaptability to different usage scenarios including motion-based applications.
3Reliability
If additional power supply means are provided for the sterilization apparatus, then UV LED operation is ensured, but device complexity and portability are reduced
Solution Approach 1:
The power supply unit is designed to universally utilize the portable terminal's existing battery, eliminating the need for separate power supply equipment. The control unit manages power allocation from the shared battery to both the terminal's primary functions and the UV LED sterilization module, reducing overall device complexity while ensuring reliable UV LED operation.
Solution Approach 2:
The power supply systems of the sterilization apparatus and the portable terminal are merged into a single integrated power management system. The terminal's battery serves dual purposes: powering both the terminal's communication functions and the UV LED sterilization module, thereby reducing the number of power supply components and improving portability.
