Vehicle Door Battery Module With Detachable Emergency Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle flaps and doors rely on permanently installed energy storage units that cannot be easily replaced and are limited in their ability to supply energy to multiple actuators or locking mechanisms, particularly in emergency situations.
Innovation Solution
A detachable energy storage unit is integrated with a lighting unit and an electrically actuated opening element, allowing for modular installation and providing energy to both the lighting unit and other actuators via detachable electrical connections, ensuring continued operation even when disconnected from the vehicle's main power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanently installed energy storage unit is used in the vehicle flap, then the energy supply for lighting and actuation is ensured, but the energy storage unit cannot be easily replaced and is limited in supplying energy to multiple actuators
Solution Approach 1:
The energy storage unit is designed as a separate, modular component that can be independently removed and replaced. It is electrically connected to the vehicle flap's control unit via a detachable electrical connection, allowing it to be segmented from the main vehicle electrical system while maintaining functional independence for emergency operations.
2Reliability
If a permanently installed energy storage unit is used, then emergency power supply is provided, but it cannot supply energy to other actuators or locking mechanisms
Solution Approach 1:
The energy storage unit is designed with universal applicability to supply power to multiple different components within the vehicle flap. It can provide emergency energy not only to the lighting unit but also to actuating elements and locking mechanisms, making it a multi-functional power source that adapts to various emergency scenarios.
3Ease of manufacture
If conventional integrated battery power supply is used, then the lighting unit and locking mechanism are powered, but the system fails when electrical connection is interrupted or damaged
Solution Approach 1:
The energy storage unit serves as a pre-positioned backup power source that is activated when the main electrical connection fails. It provides beforehand cushioning against electrical connection interruptions or damage by maintaining power supply to critical components during emergency situations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
