Bayonet Ring Connection for Tolerance-Compensating Tube Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bayonet connections face challenges in accommodating positional deviations between a socket and a tubular body due to component tolerances, leading to potential misalignment and increased production costs when precise positioning is required.
Innovation Solution
The bayonet connection design features multiple geometrically identical bayonet contours and hooks arranged in multiple planes, allowing for axial flexibility and compensation of positional deviations, with the bayonet ring and tubular body having interrupted contours and hooks that provide a form-fitting connection to secure the socket and tubular body against disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet connection is designed with a single locking mechanism requiring precise positioning, then the connection security is improved, but the manufacturing cost increases due to tighter tolerance requirements
Solution Approach 1:
The bayonet connection is divided into multiple independent locking mechanisms (first and second locking mechanisms with separate bayonet wings, hooks, and contours). Each locking mechanism can function independently, allowing the connection to achieve high security through redundancy rather than through single-point precision, thereby reducing manufacturing tolerances and costs.
2Adaptability or versatility
If multiple bayonet contours and hooks are used to compensate for positional deviations, then the adaptability to tolerances is improved, but the device complexity increases
Solution Approach 1:
The connection structure is segmented into multiple identical modular units (first bayonet wing with first hook and first contour, second bayonet wing with second hook and second contour). This modular repetition provides tolerance compensation without creating truly complex structures, as each segment follows the same design pattern.
Solution Approach 2:
The bayonet connection uses homogeneous elements - multiple bayonet wings, hooks, and contours that are essentially identical in structure and function. This homogeneity simplifies manufacturing and assembly while providing the adaptability needed to compensate for positional deviations through the redundant identical features.

AI summary
The invention relates to a bayonet connection for connecting a connector (1) to a tubular body (2), having the connector (1) with bayonet wings (7) which are arranged on the exterior of the connector (1), the tubular body (2) with at least one outer bayonet contour (5) which is arranged on the exterior of the tubular body (2), and a bayonet ring (4) with bayonet hooks (8) oriented inwards and at least one inner bayonet contour (6) oriented inwards. When the bayonet connection is in an assembled state in which the connector (1), the tubular body (2), and the bayonet ring (4) are in a locked orientation relative to one another, the bayonet ring (4) encloses the connector (1) and the tubular body (2) radially outwards and secures the connector (1) and the tubular body (2) from being pulled out of the bayonet ring (4) in that the bayonet wings (7) and the bayonet hooks (8) produce a formfitting lock to prevent the connector (1) from being pulled out, and the outer bayonet contour (5) and the inner bayonet contour (6) produce a formfitting lock to prevent the tubular body (2) from being pulled out, said formfitting locks compensating for positional deviations of the connector (1) and tubular body (2) to be connected. Additionally, the bayonet ring (4) has a plurality of inner bayonet contours (6), or the tubular body (2) has a plurality of outer bayonet contours (5), said contours being substantially geometrically identical and being arranged on multiple planes perpendicular to the central axis of the bayonet ring (4) or the tubular body (2).
