Bayonet Pressure Vessel Lid Alignment to Prevent Locking Jams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users, both inexperienced and experienced, face challenges with correctly positioning and locking the lid on a pressure vessel using bayonet locking systems, often resulting in incorrect placement and jamming during the locking process.
Innovation Solution
A positioning element that projects downwards from the lid, which fits into a recess on the container, providing a mechanical guide for precise initial positioning and ensuring correct alignment, thus facilitating easy and reliable locking through a twisting motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet locking system is used for the pressure vessel, then the locking mechanism is reliable and secure, but the ease of operation deteriorates because users have difficulty correctly positioning and locking the lid
Solution Approach 1:
The positioning element on the lid and corresponding recess in the container handle are designed to automatically guide the lid into the correct initial position before locking. This preliminary positioning action ensures that when the user places the lid on the container, it is automatically aligned with the bayonet locking segments, eliminating the need for users to manually adjust or locate the correct position, thus resolving the contradiction between reliable locking and ease of operation
Solution Approach 2:
The positioning element and recess act as an intermediary mechanism between the user and the bayonet locking system. This intermediary feature provides a mechanical guide that facilitates correct lid placement, making the complex bayonet locking operation simple and intuitive for users while maintaining the reliability of the locking mechanism
2Ease of operation
If visual aids such as symbols on the lid and handle are provided, then some guidance is given to users, but the ease of operation remains limited because visual aids alone are insufficient for correct positioning
Solution Approach 1:
The positioning element and recess are designed to be self-aligning features that automatically guide the lid into the correct position without requiring user interpretation or manual adjustment. The mechanical design itself provides the guidance function, making the system self-servicing and eliminating the need for complex visual instruction systems, thus improving ease of operation without significantly increasing device complexity

AI summary
The invention relates to a pressure vessel consisting of a container (1) and a lid (2) for placing thereon, in which case, by twisting them relative to one another, the container (1) and the lid (2) can be detachably locked together by means of peripheral locking segments (3, 4) configured along the lines of a bayonet fastening and a circumferential sealing ring is provided in the region of the edge (5) of the lid (2) and the edge (6) of the container (1) for sealing the interior of the container against a drop in pressure when said container (1) and lid (2) are in the locked position, said pressure vessel including an auxiliary device or aid for the correct positioning of the lid (2) on the container (1) and said positioning aid comprising a downward-projecting positioning element (7) located in the region of the edge (5) of the lid which, when the lid (2) is correctly positioned on top of the container (1), can be inserted into a recess (8) which is open towards the top and is located in the region of the edge (6) of the container (2).
