Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas detectors are limited in accommodating various gas detection methods due to their configuration, which only allows for the interchange of gas detection modules with the same external shape and integral housing.
Innovation Solution
A gas detector design that includes a main body with separable inflow and outflow channels, and two separable gas detection modules with interchangeable chambers, sensors, and sensor bases, allowing for different gas detection methods to be accommodated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gas detection modules with integral housings of the same external shape are used for interchangeability, then the device structure is simplified and ease of operation is improved, but the adaptability to various gas detection methods deteriorates
Solution Approach 1:
The gas detection module is divided into separable components: a chamber, a sensor unit, and a sensor base. This segmentation allows each component to be independently designed and replaced, enabling interchangeability while accommodating different detection methods through various sensor units.
Solution Approach 2:
The chamber and sensor base are designed as universal components with standardized connection interfaces that can accommodate multiple types of sensor units. This allows a single chamber-sensor base assembly to work with different sensor units for various gas detection methods, achieving both interchangeability and versatility.
2Adaptability or versatility
If various gas detection methods are accommodated with different sensor configurations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
By segmenting the module into chamber, sensor unit, and sensor base, the complexity is distributed across independent components. The standardized interfaces between segments reduce overall system complexity while allowing variety in the sensor unit component.
Solution Approach 2:
The chamber and sensor base are merged as a fixed assembly with standardized connection interfaces to the main body. This merging simplifies the overall structure by reducing the number of separate connection points while still allowing different sensor units to be integrated into the same chamber-sensor base assembly.

AI summary
A gas detector capable of accommodating various gas detection techniques is provided. The gas detector includes a main body; a first gas detection module that is separably disposed on the main body; and a second gas detection module that is separably disposed on the main body. The first gas detection module includes: a first chamber; a first gas sensor that is separably disposed on the first chamber; and a first sensor base that is separably disposed on the first gas sensor. Furthermore, the second gas detection module includes: a second chamber; and a second sensor unit that is separably disposed on the second chamber. The connection layout of the first gas detection module with respect to the main body is the same as the connection layout of the second gas detection module with respect to the main body.
