Adjustable Vehicle Stop Arrangement for Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stop arrangements for vehicle components, such as tailgates and engine bonnets, face issues with rattling due to production tolerances, which are not effectively addressed by current adjustable stop solutions that may compromise sealing and corrosion resistance.
Innovation Solution
A stop arrangement featuring a rigidly joined stud with a first threaded portion on one component and a stop part with a second threaded portion that can be screwed onto the stud, allowing for adjustable engagement without the need for openings in the components, using a latching mechanism for secure positioning and potentially incorporating an elastic buffer for damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stop arrangement with a cage and threaded stud is provided to compensate for tolerances and prevent rattling, then the adjustability and rattling prevention are improved, but the device complexity and sealing/corrosion protection are worsened due to requiring openings in components
Solution Approach 1:
The stop arrangement is divided into separate functional elements: a stud rigidly joined to the body component, a stop part with buffering element that can be adjusted, and a securing element. This segmentation allows the stop function to be implemented without requiring openings in the body panel, thus preventing rattling while maintaining structural integrity and sealing.
Solution Approach 2:
The buffering element is extracted as a separate component that can be integrated into the stop part or used independently. This allows the stop arrangement to compensate for tolerances and prevent rattling without compromising the sealing and corrosion resistance of the body components, as the buffering function is achieved through a separate element rather than requiring modifications to the body structure.
2Reliability
If a stop arrangement with buffer part is provided to compensate for tolerances, then the rattling prevention is improved, but the manufacturing precision and sealing are worsened due to requiring openings in body panels
Solution Approach 1:
The buffering element is extracted as a separate component that can be integrated into the stop part or used independently. This allows the stop arrangement to compensate for tolerances and prevent rattling without compromising the sealing and corrosion resistance of the body components, as the buffering function is achieved through a separate element rather than requiring modifications to the body structure.
Solution Approach 2:
The stop part acts as an intermediary element between the body component and the flap, providing tolerance compensation and buffering functionality without requiring direct modifications to the body panels. This intermediary approach maintains the sealing integrity of the body while achieving the desired tolerance compensation and rattling prevention.
3Adaptability or versatility
If the stop part is made adjustable by screwing onto the stud, then the adaptability for individual vehicle adjustment is improved, but the ease of manufacture is worsened due to additional assembly steps
Solution Approach 1:
The stop arrangement transitions from a fixed configuration to a dynamic, adjustable system. The stop part can be screwed onto the stud at different positions and secured using the securing element, allowing adjustment to compensate for individual vehicle tolerances. This dynamic capability is achieved through a simple screwing and securing mechanism that adds minimal assembly complexity while providing significant adaptability.
Solution Approach 2:
The stud is rigidly joined to the body component during body assembly, preparing the foundation for later adjustment of the stop part. This preliminary action allows the stop part to be easily adjusted and secured at the desired position without requiring complex assembly procedures, thus balancing adaptability with ease of manufacture.

Function Achieved in This Case
This solution provides an adjustable and aesthetically pleasing stop arrangement that compensates for vehicle-specific tolerances, reduces rattling, and avoids sealing and corrosion issues by eliminating the need for component openings, while allowing for easy assembly and maintenance.
Implementation Method 1
The stud can be connected to the respective component in any way desired, for example by adhesive bonding
Implementation Method 2
For example, the stud may be joined to the surface of the component by the stud welding that is known in the prior art
Implementation Method 3
screwing a stop part having a second threaded portion onto the stud
Implementation Method 4
fixing a latching part to the stud; screwing a stop part having a second threaded portion onto the stud, the stop part coming into latching engagement with the latching part

AI summary
A stop arrangement for forming an adjustable stop between a first component and a second component that are movable in relation to each other, in particular between a vehicle body and a flap hinge-connected to it, including a fastening element which is connected to the first component and has a first threaded portion, and including a stop part, which serves as a stop for the second component and has a second threaded portion, which can be brought into engagement with the first threaded portion in such a way that, by turning the stop part, the distance of the latter from the first component can be set.
