Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door locking systems produce annoying metallic noises during closure due to their complex structure and require significant modifications, making them costly and not suitable for widespread use with standardized components.
Innovation Solution
A modular damping module is introduced between the motor vehicle door lock and the door panel, featuring a deflection lever and damping element that interacts with the locking bolt to dampen movement, allowing for standardized and cost-effective integration without modifying the lock construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a stop device with a pivoting part is used to dampen closing noise, then noise reduction is achieved, but device complexity increases and lock construction requires far-reaching interventions
Solution Approach 1:
The damping function is segmented from the lock construction into a separate stop device with a pivoting part that can be independently attached to the door panel. This segmentation allows noise damping to be achieved without modifying the lock mechanism itself, thereby reducing overall device complexity while maintaining effectiveness.
Solution Approach 2:
The pivoting part acts as an intermediary element between the locking bolt and the door panel. It mediates the interaction by providing a dampened stopping action without requiring direct modification of either the lock or the panel, thus simplifying the overall system while reducing noise.
2Object-affected harmful factors
If existing stop devices are integrated into the lock construction, then damping effect is achieved, but ease of manufacture decreases due to required modifications
Solution Approach 1:
The stop device is segmented as a separate component from the lock construction, allowing it to be manufactured independently and attached later. This eliminates the need for far-reaching interventions in the lock construction, significantly improving ease of manufacture while maintaining the noise damping function.
Solution Approach 2:
The stop device is designed as a pre-assembled unit with the pivoting part and damping elements already in place, ready for straightforward attachment to the door panel. This preliminary preparation simplifies the integration process and makes the solution suitable for widespread application without complex manufacturing modifications.
3Ease of manufacture
If standardized components are used, then cost-effectiveness improves, but adaptability to different lock constructions decreases
Solution Approach 1:
The stop device is designed with universal mounting capabilities that allow it to be attached to various door panel types and lock constructions. The pivoting part and attachment mechanism are configured to provide consistent noise damping across different applications, making the standardized component adaptable to multiple lock systems without sacrificing cost-effectiveness.
