Solution Overview

Problem

The challenge is to efficiently operate ultraviolet (UV) light emitters in environments with limited resources, such as commercial aircraft, where persistent UV light emitters consume excessive power and generate heat, making them impractical for continuous use.

Innovation Solution

A system with sensors and a control unit that detects actions like coughs or sneezes within an enclosed space, triggering UV lamps to activate or increase intensity only when necessary, reducing power consumption and optimizing resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If persistent UV light emitters are used for continuous sanitization, then sanitization effectiveness is improved, but power consumption increases

Engineering Contradiction:
Improvesanitization effectivenessVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The UV light emitter operates in periodic cycles rather than continuously. The control system activates the UV lamp for specific durations based on detected contamination levels, then deactivates it. This periodic operation maintains sanitization effectiveness while significantly reducing overall power consumption compared to persistent continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system incorporates sensors that continuously monitor the enclosed space for contamination indicators. When contamination is detected, the control system receives feedback and activates the UV light emitter accordingly. This feedback mechanism ensures sanitization is applied only when needed, optimizing both effectiveness and energy efficiency.

Inventive Principle:
Principle #23Feedback

2Reliability

If persistent UV light emitters are used for continuous sanitization, then sanitization coverage is improved, but heat generation increases

Engineering Contradiction:
Improvesanitization coverageVSAvoidheat generation
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

By operating the UV light emitter in periodic cycles rather than continuously, the system maintains adequate sanitization coverage through targeted activation while allowing cooling periods between cycles. This reduces cumulative heat generation in the enclosed space while preserving sanitization effectiveness.

Inventive Principle:
Principle #19Periodic action

3Use of energy by moving object

If UV lamps are activated only when triggering events are detected, then power consumption is reduced, but sanitization reliability may be compromised

Engineering Contradiction:
Improvepower consumptionVSAvoidsanitization reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system uses sensors to continuously monitor for triggering events such as coughs, sneezes, or other contamination indicators. When such events are detected, the control system receives feedback and activates the UV lamps in the affected area. This feedback-driven approach ensures that sanitization is reliably applied when contamination risk is present while maintaining energy efficiency by avoiding unnecessary continuous operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system activates UV lamps in specific localized areas where triggering events are detected, rather than uniformly across the entire enclosed space. This local quality approach concentrates sanitization resources where they are most needed, maintaining reliability in high-risk zones while reducing overall power consumption.

Inventive Principle:
Principle #3Local quality
