One-Piece Bayonet Connector for Compact Releasable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting two components, such as in vehicle construction, require multiple connection means and high installation effort, occupying space and being inefficient.
Innovation Solution
A one-part male bayonet connector with a double-T-like shape, featuring a head and diametrically extending radial webs, allows for a form-fit and force-fit connection between components via a single opening, using a rotation angle less than 180° for assembly and disassembly without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ball head bolt and coupling part are used to connect two components, then a releasable connection is achieved, but the installation space required increases due to the longitudinal extension of the ball bolt
Solution Approach 1:
The patent combines the functions of the ball head bolt and coupling part into a single integrated bayonet connector. The connector features a head with a shaft extending from it, and two radial webs extending diametrically from the shaft, creating a compact single-piece fastening element that performs both connection and locking functions without requiring separate components or long longitudinal extension.
Solution Approach 2:
The invention transitions from a longitudinal connection approach (ball head bolt extending along the connection axis) to a radial approach (radial webs extending perpendicular to the shaft). This dimensional change allows the connection to be achieved through radial clamping action rather than longitudinal insertion, significantly reducing the installation space requirement while maintaining releasable connection capability.
2Strength
If a screw clip and screw are used to connect two components, then a secure connection is achieved, but the installation effort increases due to requiring two connection means
Solution Approach 1:
The patent merges the functions of the screw clip (fastening element) and screw (locking element) into a single bayonet connector component. The connector includes a head, shaft, and two radial webs that work together as one integrated unit to provide both clamping force and positional locking, eliminating the need for separate fastening and locking components.
Solution Approach 2:
The bayonet connector serves multiple functions simultaneously: it provides clamping force through the head and shaft, creates form-fit connection through the radial webs engaging with the keyhole, and enables releasable connection through rotational movement. This multi-functionality in a single component reduces installation effort while maintaining connection strength.
3Volume of moving object
If a bayonet connector with radial webs is used to connect components, then installation space is reduced and assembly is simplified, but the connector structure becomes more complex
Solution Approach 1:
The bayonet connector is segmented into distinct functional elements: a head for clamping, a shaft for insertion and rotation, and two radial webs for form-fit engagement with the keyhole. This segmentation allows each element to perform its specific function efficiently while maintaining overall structural simplicity and manufacturability as a single integrated component.

AI summary
A one-part male bayonet connector, by means of which at least two components are releasably connectable to one another in a non-destructible manner via an opening, which bayonet connector has a double T-like form in a side view, consisting of a head, a central shaft extending therefrom, and two radial webs extending diametrically from the shaft, which each comprise a fastening means of the bayonet connector facing the head so that, in addition to an interlocking bayonet connection, a frictional connection of the at least two components can be produced between the head and the fastening means of the radial webs.
