Solution Overview

Problem

The use of scent release devices in confined spaces can lead to overwhelming scents and the formation of harmful reaction products when reactive volatile compounds interact with air pollutants, posing health risks to inhabitants.

Innovation Solution

An air purification system that includes a sensor to monitor pollutant concentrations and a processor to generate a scent release signal only when the pollutant levels fall below a defined threshold, ensuring safe release of volatile compounds and maintaining a pleasant atmosphere.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If reactive volatile compounds are released into a confined space with high pollutant levels, then a scented atmosphere is created, but harmful reaction products are formed

Engineering Contradiction:
Improvescent releaseVSAvoidharmful reaction products
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors pollutant concentration levels and uses this feedback to control the scent release apparatus. The processor receives sensor data about pollutant levels and automatically adjusts whether to release volatile compounds, ensuring scent is only released when pollutant levels are below the threshold and harmful reactions are prevented

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary monitoring of pollutant concentrations before allowing scent release. By continuously sensing pollutant levels in advance and comparing them against the predefined threshold, the system ensures that volatile compounds are only released when environmental conditions are safe, preventing the formation of harmful reaction products

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If scent release devices are used in confined spaces, then a pleasant atmosphere is generated, but overwhelming scents are created

Engineering Contradiction:
Improveatmosphere generationVSAvoidoverwhelming scent
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the scent release operation based on real-time environmental conditions. Instead of continuous or fixed-interval release, the scent release apparatus operates dynamically - releasing volatile compounds only when pollutant levels permit - which prevents overwhelming scents while maintaining pleasant atmosphere when conditions are favorable

Inventive Principle:
Principle #15Dynamics

3Duration of action of stationary object

If continuous scent release is performed, then a consistent scented atmosphere is maintained, but the risk of harmful reactions increases

Engineering Contradiction:
Improvescent durationVSAvoidsafety
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The system implements periodic monitoring and conditional release rather than continuous operation. The scent release occurs in periodic cycles that are gated by safety conditions - each release cycle is preceded by verification that pollutant levels are below the threshold, maintaining scented atmosphere over time while ensuring safety through intermittent, condition-based operation

Inventive Principle:
Principle #19Periodic action
