Plug Socket Ejection Mechanism for Jam-Free Emergency Vehicle Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connection systems used in emergency vehicles often experience uneven ejection due to force application at specific points, leading to potential jamming and unreliable contact between the plug and socket, necessitating a solution for reliable operation and consistent connection.
Innovation Solution
A plug connection system with a locking mechanism that fixes the ejection element in a receiving position upon plugging, ensuring reliable contact, and automatically releases when the plug is pulled out or actuated by an automatic release mechanism, ensuring consistent ejection and reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compression spring contacts are used to eject the plug, then the plug can be ejected from the socket, but the ejection force is applied unevenly at certain points causing the plug and socket to jam
Solution Approach 1:
The ejection device is divided into multiple independent compression spring contacts (at least two) distributed around the plug connection area. Each contact applies ejection force at different locations, segmenting the total ejection force to achieve more uniform distribution and prevent jamming while maintaining the ability to eject the plug reliably
Solution Approach 2:
The compression spring contacts are strategically positioned at specific locations around the plug to create localized ejection forces. By optimizing the spatial distribution and positioning of these contacts, the system achieves uniform overall ejection effect while each contact performs its local ejection function independently
2Productivity
If the plug connection system is designed for automatic release, then no time needs to be spent on releasing, but the contacting and connection between socket and plug must always be perfect
Solution Approach 1:
The locking device is designed to automatically lock the ejection element in its initial position before the plug is even inserted. This preliminary locking action ensures that when the plug is connected, the ejection force is immediately available but contained, allowing for rapid automatic release while maintaining perfect contact during the connected state
Solution Approach 2:
The system automatically maintains perfect contacting and connection through the self-locking mechanism of the locking device and the self-adjusting compression spring contacts. The compression springs automatically adjust to maintain optimal contact pressure, and the locking device automatically engages to hold the connection stable without requiring manual intervention

Function Achieved in This Case
The system provides reliable and automatic ejection and reconnection of the plug, ensuring consistent contact and preventing jamming, while ensuring proper alignment and secure engagement of contacts for efficient energy and data transfer in emergency vehicles.
Implementation Method 1
the ejection element is designed as an ejection sleeve that can be moved from the receiving position into the ejection position by means of a spring element
