Innovation Solution
A gas detecting device with a modular design featuring a casing, gas transporting actuator, valve, and external sensors that can be easily swapped, allowing for the detection of various gases like oxygen, carbon monoxide, carbon dioxide, and volatile organic compounds, with a piezoelectric blower or actuator for air transportation and a microprocessor for data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gas detecting device uses fixed sensor configuration, then device structure is simple, but adaptability to different user requirements deteriorates
Solution Approach 1:
The gas detecting device is divided into modular components: a fixed base unit (casing with airflow chamber and gas transporting actuator) and detachable external sensors. This segmentation allows users to attach different sensor modules to the same base unit, achieving versatility without requiring multiple complete devices, thus resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The base unit is designed with universal interfaces and standardized connection channels that can accommodate multiple types of external sensors. The gas transporting actuator and valve system provide universal gas flow control functionality that works with various sensor types, enabling one device structure to serve multiple detection purposes.
2Ease of repair
If gas detecting device uses detachable external sensor, then ease of replacement improves, but device complexity increases
Solution Approach 1:
By separating the sensor component from the base unit through detachable connections, the design enables easy replacement of sensors without affecting the main device structure. The segmentation creates independent replaceable modules, improving ease of repair while maintaining overall structural organization.
Solution Approach 2:
The external sensor is designed to attach to and nest within the connection channel of the base unit, creating a compact integrated appearance when assembled. This nesting approach allows easy attachment/detachment while minimizing the increased complexity when the components are combined.
3Adaptability or versatility
If gas detecting device has multiple branch channels, then adaptability to different gas detection needs improves, but device complexity increases
Solution Approach 1:
The gas flow path is segmented into multiple branch channels within the airflow chamber, each capable of connecting to different external sensors. This segmentation allows simultaneous or selective detection of multiple gas types through organized parallel pathways, achieving enhanced capability while maintaining structured simplicity.

AI summary
A gas detecting device includes a casing, at least one gas transporting actuator, at least one valve and at least one external sensor. The casing has an airflow chamber, an inlet, a branch channel and a connection channel. The airflow chamber communicates with the exterior of the casing through the inlet, and the branch channel communicates with the airflow chamber and the connection channel. The gas transporting actuator is disposed within the branch channel for transporting air into the airflow chamber and the branch channel from the inlet. The valve is disposed between the connection channel and the branch channel for controlling the air to flow into the connection channel. The external sensor is detachably disposed within the connection channel and has a sensor for measuring the air in the connection channel.
