Vehicle Safety System External Plug for Battery Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety systems for vehicles, particularly those with lithium-ion batteries, do not adequately protect occupants and rescue workers from electric shocks during accidents or maintenance, as they require access to conductive components and lack effective disconnection mechanisms, posing risks and inefficiencies.
Innovation Solution
A safety system with an operable surface and charging slot outside the vehicle, where the operating plug and charging slot are combined to de-energize the vehicle by mechanically separating high-voltage and low-voltage circuits, using an electrically non-conductive operable area that can be secured against unauthorized operation, allowing safe battery disconnection without touching conductive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the service device is concealed on the vehicle and requires access to conductive components for operation, then the battery can be disconnected for safety, but the rescue workers are exposed to electric shock risks and the operation becomes complex and time-consuming
Solution Approach 1:
The patent introduces an intermediary mechanism - the service plug with integrated charging slot and operable surface - that mediates between the rescue workers and the high-voltage battery system. This plug serves as a safe interface that allows disconnection without direct contact with conductive components, eliminating the electric shock hazard while maintaining reliable battery disconnection capability.
Solution Approach 2:
The service function is extracted from the concealed interior location and brought to the exterior of the vehicle through the service plug. This extraction allows rescue workers to access and operate the disconnection mechanism from outside the vehicle, eliminating the need to open the vehicle or touch conductive components, thus removing the electric shock risk while maintaining safety reliability.
2Stability of the object's composition
If the service device is mounted on the battery housing with low center of gravity for driving stability, then the vehicle achieves good driving dynamics, but the service device becomes difficult to access for maintenance and emergency operations
Solution Approach 1:
The service function is segmented from the battery housing structure and implemented as a separate, movable service plug that can be positioned at the exterior of the vehicle. This segmentation allows the battery housing to remain in its optimal low center of gravity position for driving stability, while the service plug provides easy exterior accessibility for rescue workers and maintenance personnel.
Solution Approach 2:
The service access point is moved from the vertical dimension (concealed interior or low-position mounting) to the exterior horizontal dimension of the vehicle. This dimensional change allows rescue workers to access the service device from outside the vehicle at an ergonomic height, improving ease of operation while the battery housing maintains its optimal position for driving stability.
3Reliability
If the operating plug and charging slot are combined outside the vehicle with mechanical connection to operable surface, then safe battery disconnection is achieved without touching conductive components, but the device structure becomes more complex
Solution Approach 1:
The operating plug and charging slot are merged into a single integrated component located outside the vehicle. This combination eliminates the need for separate disconnection and charging mechanisms, reducing the overall device complexity while maintaining the safety function of disconnecting the battery without touching conductive components. The integrated design also simplifies the user interface by providing both functions in one location.
