Solution Overview

Problem

High-touch devices such as EFTPOS and ATM terminals, and other public surfaces, pose a significant risk for the spread of infectious agents like bacteria and viruses due to frequent contamination and inadequate decontamination methods, which can lead to increased transmission risks during pandemics.

Innovation Solution

A system incorporating a power source and decontamination areas with UV-C light sources that emit ultraviolet radiation to inactivate microorganisms, designed for integration into devices or as separate units for decontaminating surfaces and contact areas, ensuring effective disinfection without damaging the devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frequent cleaning of EFTPOS and ATM terminals is performed using liquid chemicals, then the decontamination effectiveness is improved, but the device lifespan deteriorates due to unintentional damage

Engineering Contradiction:
Improvedecontamination effectivenessVSAvoiddevice lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent replaces chemical cleaning mechanisms with UV-C light irradiation. The UV-C LED array emits ultraviolet radiation that inactivates microorganisms on contact surfaces without requiring liquid chemicals, thereby eliminating damage to electronic components while maintaining decontamination effectiveness

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the decontamination method from chemical (liquid) to physical (UV-C radiation). By altering the fundamental parameter of the cleaning agent from chemical substance to electromagnetic radiation, the system achieves decontamination without the harmful side effects of chemicals on electronic devices

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If hand sanitizer is used by individual users, then personal hygiene is improved, but the overall transmission risk worsens due to improper usage and insufficient coverage

Engineering Contradiction:
Improvepersonal hygieneVSAvoidtransmission risk reduction
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables automatic decontamination of devices by integrating UV-C LEDs that activate when the device is idle or between uses. The device self-decontaminates without requiring user action, ensuring consistent hygiene standards regardless of user behavior or availability of hand sanitizer

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The UV-C light acts as an intermediary decontamination method between user interactions. Instead of relying directly on user-applied hand sanitizer, the system uses UV-C radiation as a mediating agent to eliminate pathogens on the device surface, providing an additional layer of protection

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If conventional pens are used for signing in, then the functionality is improved, but the infection risk worsens due to contamination of the pen surface

Engineering Contradiction:
Improvesigning functionalityVSAvoidinfection risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces conventional ink pens with UV-C integrated pens or surfaces. Instead of using a physical writing instrument that accumulates contamination, the system uses UV-C radiation to decontaminate the signing surface or pen between uses, eliminating the infection vector while maintaining the signing function

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
