Conventional air quality monitoring systems are limited in providing localized air quality information, as they primarily rely on stationary monitoring stations, making it difficult for individuals to obtain real-time air quality data in specific areas.
Innovation Solution
A compact gas detecting module integrating a base, micro pump, driving circuit board, gas sensor, and thin film, designed to be embedded in portable electronic devices, enabling the detection and analysis of air quality through a modular structure that includes a gas-inlet-groove region, gas-flowing-path region, and gas-outlet-groove region, facilitating lateral or vertical gas flow and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional stationary monitoring stations are used, then air quality information can be obtained, but the information is limited to large area coverage and cannot provide localized real-time data
Solution Approach 1:
The gas detecting module is divided into functionally independent regions: a micro pump loading region for pump integration, a detection region for sensor placement, and a gas flowing path region for fluid transport. This segmentation allows each component to be optimized independently while maintaining compact overall dimensions suitable for portable devices.
Solution Approach 2:
The micro pump is embedded within the micro pump loading region of the base structure, and the gas sensor is positioned within the detection region. This nested arrangement maximizes space utilization and reduces the overall module size, enabling integration into portable electronic devices while maintaining localized detection capability.
2Ease of manufacture
If a compact modular structure is used for portable device integration, then ease of integration is improved, but manufacturing precision requirements increase
Solution Approach 1:
The gas inlet groove, gas outlet groove, and associated apertures are pre-formed as integral features of the base structure during manufacturing. This preliminary formation ensures precise alignment of gas flow paths with the micro pump and gas sensor, reducing assembly complexity and maintaining manufacturing feasibility despite the compact design.
3Productivity
If lateral gas flow path is implemented, then gas detection efficiency is improved, but structural complexity increases
Solution Approach 1:
The gas inlet groove, gas outlet groove, and internal flow channels are merged into a unified gas flowing path system that is pre-integrated into the base structure. This combining approach enables efficient lateral gas flow from the micro pump through the detection region to the gas sensor while minimizing the number of discrete components and assembly steps.

Implementation Method 1
The micro pump accelerates the flow of the gas, and the gas is laterally inhaled relative to the gas detecting module into the gas-flowing-path region through the gas-outlet concave of the sidewall
Implementation Method 2
The gas sensor is disposed on and electrically connected to the driving circuit board and accommodated within the detection region to detect the gas flowing therethrough

AI summary
A gas detecting module is disclosed. A gas-inlet concave and a gas-outlet concave are formed on a sidewall of a base. A gas-inlet-groove region and a gas-outlet-groove region are formed on a surface of the base. The gas-inlet concave is in fluid communication with a gas-inlet groove of the gas-inlet-groove region, and the gas-outlet concave is in fluid communication a gas-outlet groove of the gas-outlet-groove region. The gas-inlet-groove region and the gas-outlet-groove region are covered by a thin film to achieve the effectiveness of laterally inhaling and discharging out gas relative to the gas detecting module.
