Gas Sensor Guide Rail Latch for Stable Detector Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas sensors are not reliably and removably connected to gas leak detectors, which can lead to unstable connections and potential mechanical forces affecting gas and signal transmission.
Innovation Solution
A guide rail system with a fastening claw and a spreading element is used to securely connect and disconnect a gas sensor from a gas leak detector, utilizing elastic spring legs and inclined portions on retaining arms to manage the connection and disconnection process without exerting mechanical forces on the gas connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening mechanism is used to securely connect the gas sensor to the gas leak detector, then connection reliability is improved, but the device complexity increases
Solution Approach 1:
The spring legs automatically engage with the sensor housing and gas connectors upon insertion, providing self-latching functionality without requiring additional actuation mechanisms. The spreading element utilizes elastic deformation of the spring legs to achieve disengagement, allowing the fastening system to secure and release the connection through simple mechanical actions.
Solution Approach 2:
The fastening mechanism is divided into independent spring legs, each capable of engaging and retaining the sensor housing separately. This segmentation allows the system to provide reliable connection through multiple independent latching points while maintaining simplicity in the overall structure.
2Stability of the object's composition
If the gas sensor is firmly retained by the fastening claw, then connection stability is improved, but ease of disconnection deteriorates
Solution Approach 1:
The spring legs are designed as elastic elements that can dynamically adjust between a closed latching state for secure retention and an opened state for easy disconnection. The dynamic elasticity allows the system to maintain firm connection during operation while enabling simple removal when needed.
Solution Approach 2:
The spreading element acts as an intermediary tool that applies force to the spring legs to open them for disconnection. This intermediary mechanism allows easy removal without requiring direct manipulation of the latched components, maintaining both connection stability and ease of disconnection.
3Ease of operation
If the spreading element is used to disengage the latching boss, then ease of disconnection is improved, but device complexity increases
Solution Approach 1:
The spreading element utilizes the inherent elasticity of the spring legs to achieve disengagement. By simply pushing the spreading element in the insertion direction, the spring legs are automatically opened and the latching boss is released, eliminating the need for complex actuation mechanisms or additional tools.
Solution Approach 2:
The spreading element serves as a simple intermediary tool that translates user input into the opening of spring legs. This single-component intermediary mechanism provides ease of disconnection without adding significant complexity to the overall system.
4Ease of operation
If mechanical forces are applied to disconnect the fastening claw, then disconnection capability is improved, but risk of damaging gas connectors increases
Solution Approach 1:
The disconnection force is applied to the spring legs separately from the gas connectors. The spring legs act as isolated sacrificial elements that absorb the mechanical stress of disengagement, protecting the gas connectors from damaging forces.
Solution Approach 2:
The spreading element serves as an intermediary that applies disconnection forces to the spring legs rather than directly to the gas connectors. This intermediary action isolates the vulnerable gas connectors from mechanical stress while still enabling effective disconnection.

AI summary
Disclosed is a connecting device for connecting a gas sensor to a gas leak detector. The gas sensor includes an elongate sensor housing. The gas leak detector includes at least one gas connector adapted to be connected to the gas sensor. A guide rail connects to the gas leak detector, engaging with the sensor housing such that the gas connectors engage with at least one complementary second gas connector. A fastening claw includes two elastic spring legs arranged at one of the sensor housing and the gas leak detector. Each of the two spring legs includes a latching boss engaging the frontal end of the gas sensor opposite the second gas connector and a spreading element having two retaining arms. Each retaining arm includes a pulling edge, an inclined insertion portion along which the latching boss grips and pivots the spring leg, and an inclined disengagement portion.
