Solution Overview

Problem

Current air quality monitoring systems struggle to provide real-time detection of suspended particles and other pollutants in indoor environments due to unstable gas flows and fixed monitoring locations, which can lead to inadequate protection of human health.

Innovation Solution

A regulation-device control circuit for a gas detection module is integrated with indoor cleaning devices and cloud computing services to enable real-time air pollution detection and coordinated regulation operations, using a microcontroller unit (MCU) connected to sensing elements and communication modules to control filtration and cleaning processes.

Solution Approach 1:

The patent combines multiple functions (gas detection, data processing, wireless communication, and control) into a single integrated detection module. The microcontroller unit integrates sensor data from multiple sensors (gas sensors, particle sensors, temperature sensors, humidity sensors), processes the data locally, and controls execution units (air purifiers, windows, doors) all within one module, eliminating the need for separate centralized systems and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The detection module autonomously processes sensor data through local algorithms to determine air quality levels and automatically controls execution units based on predefined thresholds. The system performs self-diagnosis and self-adjustment without requiring cloud computing or external intervention, enabling the device to serve itself and making the system more reliable while reducing complexity.

Inventive Principle:
Principle #25Self-service

2Productivity

If multiple sensors and processing units are integrated in each cleaning device, then real-time detection capability is improved, but the device complexity increases

Engineering Contradiction:

Solution Approach 1:

The detection module is designed as a universal multi-functional unit that can detect multiple types of pollutants (gas, particles, temperature, humidity), process data through integrated algorithms, communicate wirelessly, and control various execution units (air purifiers, windows, doors). This multi-functional design consolidates what would otherwise require multiple separate devices and control circuits into a single versatile module.

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

Solution Approach 2:

The patent implements a nested structure where the microcontroller unit is embedded within the detection module, which contains multiple sensor elements. The microcontroller nests data processing algorithms within the hardware architecture, and the entire detection module nests within the air cleaning system. This nested organization allows complex functionality to be packaged in a compact, manageable form factor.

Inventive Principle:
Principle #7Nested doll (Nesting)
