Solution Overview

Problem

Current systems fail to effectively and rapidly detect and control indoor air pollution sources, leading to unsafe indoor air quality, as they are influenced by both outdoor conditions and poor indoor air circulation, which can include particulate matters, CO2, TVOC, formaldehyde, bacteria, and viruses.

Innovation Solution

A system comprising multiple gas detection devices and a central control monitoring device connected to a cloud platform for intelligent computation and communication, which selectively activates gas exchange and filtration devices to direct airflow and filter pollutants, ensuring indoor air quality meets safe standards by approaching zero pollution levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If air conditioners or air cleaners are utilized for improving the indoor air quality, then the indoor air quality is improved, but the system cannot effectively and rapidly detect and control indoor air pollution sources

Engineering Contradiction:
Improveindoor air qualityVSAvoiddetection and control speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system divides the indoor space into multiple monitoring zones with distributed gas detection devices, allowing parallel detection of pollution sources across different locations. This segmentation enables rapid identification of specific pollution sources without requiring a single complex detection system to scan the entire space sequentially.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements real-time feedback through continuous monitoring of air quality parameters by gas detection devices, with the central control unit receiving data and immediately adjusting gas exchange and filtration device operations. This closed-loop feedback mechanism enables rapid response to pollution sources, automatically adjusting airflow and filtration based on detected pollutant levels.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If gas detection devices and control systems are deployed throughout the indoor space, then the detection capability is improved, but the device complexity increases

Engineering Contradiction:
Improveair pollution detection capabilityVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The gas detection devices are designed as multi-functional units that simultaneously detect multiple types of pollutants (particulate matters, CO2, TVOC, formaldehyde, bacteria, viruses) and integrate communication, data processing, and control signaling capabilities. This universality reduces the need for separate specialized devices for each function, thereby simplifying the overall system structure while maintaining comprehensive detection capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the detection, communication, and control functions into an integrated networked architecture where gas detection devices, central control unit, and gas exchange/filtration devices operate as a unified system. This consolidation of functions across components reduces individual device complexity while achieving sophisticated overall system performance through coordinated operation.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple gas exchange and filtration devices are activated to filter pollutants, then the air quality is improved, but the energy consumption increases

Engineering Contradiction:
Improveair quality safetyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system activates only the necessary number of gas exchange and filtration devices based on real-time pollution detection, rather than running all devices continuously. The central control unit calculates the optimal activation strategy by comparing pollution levels against safety thresholds and determining the minimum required filtration capacity, thereby reducing energy consumption while maintaining air quality safety.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically adjusts the operation of gas exchange and filtration devices based on varying pollution levels, outdoor air quality conditions, and indoor occupancy. The central control unit continuously modifies device activation and airflow rates in response to changing conditions, optimizing energy consumption while ensuring air quality remains within safe limits throughout the indoor space.

Inventive Principle:
Principle #15Dynamics
