Gas Sensor Kit Locking Claw Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas sensor kits face difficulties in attaching and detaching the gas supply unit during therapy, particularly with fine prongs, which can lead to errors and interruptions in oxygen or therapeutic gas administration.
Innovation Solution
A gas sensor kit with a gas supply unit that includes a tube connected to a nasal adapter, featuring a convex portion on the gas sensor and locking claws on the supply unit for easy attachment and detachment, allowing secure and efficient connection with the nasal adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fine prong is used for oxygen administration, then gas delivery precision is improved, but ease of operation deteriorates due to difficulty in attachment and detachment
Solution Approach 1:
The gas supply unit is divided into separate components: a connection portion with locking claws that attaches to the gas sensor, and a tube portion for gas delivery. This segmentation allows the precision gas delivery function to be maintained while the connection mechanism provides easy attachment and detachment through the locking claw design that engages with convex portions on the gas sensor.
2Manufacturing precision
If a fine prong is used for oxygen administration, then gas delivery precision is improved, but reliability deteriorates due to risk of erroneous closure during attaching and detaching
Solution Approach 1:
The locking claws are pre-configured in a positioned state that automatically engages with the convex portions on the gas sensor when the connection portion is attached. This preliminary positioning action ensures reliable connection without requiring precise manual alignment during operation, preventing erroneous closure while maintaining the precision gas delivery capability of the fine prong.
3Reliability
If a complex attachment mechanism is used, then reliability of connection is improved, but device complexity increases
Solution Approach 1:
The connection portion with locking claws is designed to automatically engage with the gas sensor when brought into proximity. The locking claws self-position and lock onto the convex portions without requiring complex alignment procedures or additional fastening steps. This self-service mechanism achieves reliable connection while keeping the attachment mechanism simple and intuitive to operate.
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
Enables simple and secure attachment and detachment of the gas supply unit to the gas sensor, ensuring continuous oxygen or therapeutic gas administration without interruptions, even during therapy.
Implementation Method 1
a gas sensor that is configured to measure a gas concentration of an exhalation gas of a subject
Implementation Method 2
a nasal adapter configured to be disposed in a vicinity of nostrils of the subject for introducing the exhalation gas of the subject to the gas sensor
Implementation Method 3
each of the gas supply unit and the gas sensor has an attachment and detachment mechanism by which the gas supply unit is capable of being attached to and detached from the gas sensor

AI summary
A gas sensor kit includes a gas sensor that measures a gas concentration of an exhalation gas of a subject and a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject. In the gas sensor, the gas sensor has a convex portion that is supported when connected with the gas supply unit, and the gas supply unit has at least one locking claw that supports the convex portion when connected with the gas sensor.
