Problem
Existing gas detectors are not adaptable to different tasks quickly and face issues with incorrect measurements due to target gas absorption by conventional elastic materials used in adapters, leading to false alarms or undetected gases.
Innovation Solution
A gas detector with a detachable adapter featuring a fluororubber filling that minimizes target gas absorption, allowing operation with and without the adapter, and includes a calibration mechanism to adapt to various environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional elastic materials are used in adapters, then the adapter provides basic sealing and gas guidance functions, but the target gas is absorbed by the elastic material leading to incorrect measurements and false alarms
Solution Approach 1:
The patent changes the material parameter of the filling from conventional elastic materials to fluororubber, which has different chemical properties that minimize target gas absorption while maintaining the necessary sealing and gas guidance functions, thereby eliminating measurement errors caused by gas absorption
Solution Approach 2:
The patent uses fluororubber as a composite material that combines the benefits of elasticity for sealing with low gas absorption properties, creating a filling material that performs multiple functions without the harmful side effect of target gas absorption
2Adaptability or versatility
If the gas detector is designed for specific task adaptation, then it can be optimized for particular detection scenarios, but it takes time to adapt to different tasks and environments
Solution Approach 1:
The patent divides the gas detector into modular components including a detachable adapter with filling that can be quickly exchanged, allowing the device to be adapted to different tasks by simply changing the adapter assembly without requiring time-consuming recalibration or complex reconfiguration
Solution Approach 2:
The adapter with fluororubber filling is pre-assembled and ready for immediate use in different environments, eliminating the need for on-site material preparation or recalibration when switching between detection tasks
3Adaptability or versatility
If the adapter is made detachable to enable quick adaptation, then the device becomes more versatile, but the connection between adapter and housing becomes more complex
Solution Approach 1:
The adapter is designed with a universal connection interface that can be attached to and detached from the housing quickly, and the same adapter structure serves multiple functions including sealing, gas guidance, and environmental protection, reducing the need for separate components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances measurement reliability by reducing gas absorption errors and enabling quick adaptation to different tasks, ensuring accurate detection of target gases without costly recalibration.
Implementation Method 1
The filling is made of a cured foam. This foam is a a fluororubber (fluorocarbon rubber, fluorinated rubber) or comprises at least one fluororubber. The filling minimizes target gas absorption
Implementation Method 2
The adapter or each adapter comprises an outer shell and an elastic filling. The elastic filling can be reversibly compressed

AI summary
A gas detector (100) includes a housing (1), a sensor in the housing and an adapter (3, 3.1). An inlet in the housing provides a fluid connection between the sensor and the environment. The sensor is configured to measure a detection variable that correlates with the concentration of a target gas to be detected. The adapter (3, 3.1) can be detachably and fluid tightly mounted on the housing. A fluid guide unit can be connected to a connection element (12, 12.1) of the adapter (3, 3.1). When the adapter (3, 3.1) is attached, an elastic filling (6, 6.1) is located between an outer shell (9, 9.1) of the adapter (3, 3.1) and the sensor. The filling (6, 6.1) is made of a cured foam. The foam includes fluorinated rubber. A channel (10, 10.1) in the filling provides a fluid connection between the connection element (12, 12.1) and the sensor.
