Cartridge Connector Alignment Structure for Directed Gas Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection structures for cartridges and gas consumption devices may fail to release gas in a predetermined circumferential direction due to improper alignment, especially in high temperature environments.
Innovation Solution
A connection structure featuring positioning teeth and grooves on connectors that allow for precise alignment and rotation of a cartridge within a gas consumption device, ensuring gas release in a predetermined direction via a safety valve, even under extreme conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cartridge is detachably connected to a gas consumption device, then the cartridge can be easily installed and removed, but the gas may not be released in the predetermined circumferential direction due to improper alignment
Solution Approach 1:
The patent employs asymmetric positioning teeth and positioning grooves with different orientations on the cartridge and gas consumption device. The positioning teeth on the cartridge outer circumferential surface are arranged at specific angles, while the positioning grooves on the gas consumption device inner circumferential surface are oriented differently, ensuring that the cartridge can only be installed in one specific angular position. This asymmetric design guarantees that the safety valve aligns with the exhaust port, enabling reliable gas release in the predetermined circumferential direction while maintaining easy installation through the simple engageable connection structure.
2Measurement precision
If positioning teeth and grooves are provided on connectors, then precise alignment is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the alignment function into separate components: positioning teeth on the cartridge connector and corresponding positioning grooves on the gas consumption device connector. This segmentation allows each component to be independently designed and manufactured with simple geometries, while collectively achieving precise angular alignment. The positioning teeth are simple protrusions and the grooves are simple recesses, avoiding complex mechanisms while ensuring accurate positioning through their complementary shapes and arrangements.

AI summary
Among the connectors between the cartridge and the gas consumption device, one of the connectors has a plurality of positioning teeth protruding from the outer circumferential surface formed at intervals in the circumferential direction around the axis. A plurality of positioning grooves having groove widths corresponding to circumferential tooth widths of the positioning teeth are formed at intervals in the circumferential direction of the inner peripheral surface of the other connector. The inner peripheral surface of the other connector is further formed with a rotation groove in which the positioning teeth that have passed through the positioning groove rotate around the axis. A stopper is formed in the rotation groove to which one positioning tooth comes into contact so as to limit rotation of the cartridge at a predetermined rotation angle.
