Bayonet Water Connection With Locking End Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for water-conducting components, such as pipes and fittings, require tools for installation and maintenance, are difficult to handle in cramped spaces, and often result in fittings becoming irreversibly locked, making replacement and modification cumbersome.
Innovation Solution
A connection arrangement featuring a locking mechanism that defines the end position without requiring tools, utilizing radial seals and a latching mechanism with a spring-loaded locking element, allowing components to be rotated without screws or threads, and featuring a visible indicator for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flange connections with screws and tools are used, then reliable connection is achieved, but ease of operation deteriorates due to tool requirements and difficulty in cramped spaces
Solution Approach 1:
The invention extracts and removes the screw and thread elements from the connection system, replacing them with a direct bayonet-style rotational connection. This eliminates the need for tools and complex tightening operations while maintaining connection reliability through the locking mechanism and seal engagement.
Solution Approach 2:
Instead of using threads that require rotational tightening in one direction, the invention uses a bayonet connection where the component is inserted and then rotated a small angle to lock into place. This inverts the conventional approach by using a small rotation after insertion rather than continuous rotational tightening.
2Adaptability or versatility
If fittings are connected in series with multiple components, then functional requirements are met, but device complexity increases and space requirements grow
Solution Approach 1:
The connecting fitting is designed with universal male and female connection interfaces that can accommodate various valve types and configurations. The standardized bayonet connection allows different functional components to be interconnected using the same connection mechanism, reducing the need for specialized connection hardware for each component type.
3Strength
If screws and threads are used for connection, then secure fastening is achieved, but ease of manufacture deteriorates due to parallel thread requirements for multiple channels
Solution Approach 1:
The invention removes the requirement for parallel threads in multiple channels by using a bayonet connection system. The rotational locking mechanism provides secure fastening without requiring threaded holes or screw fasteners in each channel, significantly simplifying the manufacturing process for multi-channel components.

AI summary
A connection arrangement for water-carrying components (10, 12) comprising a first water-carrying component (12) with a first contact surface (26); a second water-carrying component (10) which can be connected to the first component (12) by means of a bayonet or other rotary closure rotatable about the connection axis via a second contact surface (22); and a seal (30, 38) between the first and the second contact surface (22, 26); characterized in that, in addition to the closure, a locking mechanism (64, 66) is provided which engages when an end position is reached and, in the engaged position, counteracts a rotation of the components (10, 12) in the opposite direction.
