Rotary Connector With Three-Point Locking for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for electromedical devices and equipment carriers are not efficient in providing a quick, safe, and easy method for connecting and disconnecting devices without the risk of slippage or falling, especially for heavier devices.
Innovation Solution
The device connection device employs first and second rotary anchor couplings with a suspension device, forming a three-point hitch that allows for secure coupling and vibration-resistant connections, with pivoted levers for manual operation and non-circular locking members for secure anchoring, enabling easy assembly and disassembly without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a connection system uses simple insertion without suspension support, then the coupling process is quick, but heavier devices may slip or fall during coupling
Solution Approach 1:
The suspension device engages in advance to support the device weight before the rotary anchor couplings are fully locked, preventing slippage or falling during the coupling process. This preliminary support action ensures safety before the final locking mechanism is activated.
2Reliability
If rotary anchor couplings are used for secure connection, then connection reliability is improved, but the coupling process becomes more complex
Solution Approach 1:
The connection system is divided into three independent coupling points: one suspension device and two rotary anchor couplings. Each component performs a specific function (weight support, rotational locking), simplifying the design and assembly of each individual part while achieving overall secure connection through their combination.
3Reliability
If multiple coupling points are used to prevent slippage, then connection reliability is improved, but the device complexity increases
Solution Approach 1:
The suspension device and rotary anchor couplings are integrated into a unified three-point hitch system where components work together synergistically. The suspension device provides vertical support while the rotary anchors provide horizontal locking, creating a cohesive connection system that achieves high reliability without excessive complexity.
4Reliability
If the rotary anchors require precise alignment for locking, then connection reliability is improved, but the ease of operation decreases
Solution Approach 1:
The rotary anchor couplings allow dynamic adjustment during the coupling process. The rotatable nature of the anchors enables them to self-align or be easily maneuvered into the correct position by hand, accommodating minor misalignments without requiring precise initial positioning, thus maintaining ease of operation while ensuring reliable locking.

AI summary
A connecting device (12) according to the invention serves to couple two devices (10, 11) arranged one above the other or to couple a device (10) to a device carrier (55). The device connecting device comprises at least two swivel couplings. Preferably, the two swivel couplings are supplemented by a suspension device, so that the three coupling means are preferably arranged in a horizontal or an inclined plane. The suspension device operates on the hook/eye principle, while the swivel couplings provide a positive locking connection by axially inserting a non-circular swivel anchor into an anchor socket and securing it by rotation. This connection is easy to make and release and is also very vibration-resistant.
