Motor Vehicle Door Holder Integrating Locking and Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle closing devices face challenges in implementing holding functions and reducing noise in limited installation spaces, where known solutions like damping means and spring plates are insufficient due to space constraints.
Innovation Solution
A motor vehicle closing device with a holding device that doubles as a locking mechanism, using a plastic damping element or a holder with integrated damping means to secure the lock holder in the main latching position, eliminating the need for additional damping components and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If damping means or spring plates are added to reduce noise between lock holder and closing device, then noise behavior is improved, but device complexity and installation space requirements worsen
Solution Approach 1:
The holding device is designed to combine multiple functions: it serves as both the holding mechanism for the vehicle part and as the locking means for the lock holder. By integrating the locking function into the holding device, the patent eliminates the need for separate damping means or spring plates, thereby reducing component count while maintaining noise reduction capabilities through the holder's interaction with the closing device
Solution Approach 2:
The holding device is designed as a multi-functional component that simultaneously performs holding, locking, and noise reduction functions. The holder within the holding device interacts with both the vehicle part and the lock holder, providing universal functionality that replaces multiple separate components and reduces overall device complexity
2Object-affected harmful factors
If damping means are added to reduce noise between lock holder and closing device, then noise behavior is improved, but installation space requirements worsen
Solution Approach 1:
The patent merges the locking and holding functions into a single holding device, eliminating the need for additional damping means that would require separate installation space. The holder within the holding device directly interacts with the closing device to provide noise reduction without requiring extra space for separate damping components
Solution Approach 2:
The holding device serves multiple purposes including holding the vehicle part, locking the lock holder, and reducing noise through the holder's interaction with the closing device. This multi-functionality allows the patent to achieve noise reduction without adding separate damping components that would increase installation space requirements
