Motor Vehicle Lock Emergency Power Compartment for Tool-Free Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle locks with electromotive drives face issues with emergency power sources that degrade over time, leading to potential failures in power supply, making it difficult to maintain and replace these sources efficiently.
Innovation Solution
The emergency power source is housed in a compartment with a detachable lid, utilizing a mechanical force, such as a spring or gravity, to expose it partially for easy removal and replacement, ensuring no additional tools are needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency power source is permanently installed inside the lock housing, then the power supply reliability is improved, but the ease of replacement deteriorates due to aging and potential failures
Solution Approach 1:
The emergency power source is segmented from the main lock housing by placing it in a separate, detachable compartment. This allows the power source to be independently accessed and replaced without disassembling the entire lock mechanism, resolving the contradiction between maintaining reliable power supply and enabling easy replacement when the power source ages or fails.
Solution Approach 2:
The emergency power source is extracted from permanent integration into the lock housing and placed in a removable compartment that can be detached from the outside. This extraction enables the power source to be taken out for replacement when needed, while still being housed within the lock structure to maintain reliability, thus resolving the contradiction between these two requirements.
2Object-affected harmful factors
If the emergency power source is placed in a sealed compartment, then the protection from environmental factors is improved, but the ease of access and replacement deteriorates
Solution Approach 1:
A detachable compartment serves as an intermediary between the locked housing (providing protection) and the need for easy access. The compartment itself is sealed to protect the power source from moisture and dust, yet it can be removed as a complete unit from the outside, providing easy access for replacement without requiring disassembly of the protective housing structure.
Solution Approach 2:
The compartment transitions from a static, permanently sealed state to a dynamic, removable state. When installed, it provides sealed protection against environmental factors. When needed for replacement, it can be dynamically removed from the outside, thus resolving the contradiction between maintaining protection and enabling easy access.
3Ease of repair
If the emergency power source is made easily accessible for replacement, then the ease of maintenance is improved, but the protection from environmental factors deteriorates
Solution Approach 1:
The power source is extracted into a separate compartment that can be removed as a complete unit. This allows the entire sealed compartment to be taken out for maintenance, providing easy access without exposing the power source to environmental factors during normal operation. The compartment itself becomes the protective barrier that travels with the power source.
4Ease of repair
If the compartment structure is added for removable power source, then the ease of replacement is improved, but the device complexity increases
Solution Approach 1:
The lock system is segmented into modular components: the main housing and the detachable compartment containing the power source. This segmentation adds minimal structural complexity (a simple removable compartment) while dramatically improving ease of replacement, as the compartment can be independently accessed and replaced without affecting the rest of the lock mechanism.
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
Facilitates quick and tool-free replacement and maintenance of the emergency power source, enhancing its service life by protecting it from moisture and dust while maintaining space efficiency.
Implementation Method 1
an additional (mechanical) source of force is provided which, after removal of the lid, transfers the emergency power source into an at least partially exposed position
Implementation Method 2
utilizing a mechanical force, such as a spring or gravity, to expose it partially

AI summary
A motor vehicle lock, in particular a motor vehicle door lock, which is equipped with an electromotive drive and an electric emergency power source for an emergency actuation of the drive. The emergency power source is arranged in the interior of a motor vehicle lock housing. According to the invention, the emergency power source is accommodated in an exchangeable manner in a compartment that can be closed with a detachable lid, wherein an additional power source is provided, which, after removal of the lid, transfers the emergency power source into an at least partially exposed position in relation to the motor vehicle door lock housing.
