Vehicle Bump Stop Positioning Aid for Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stop buffers for vehicles fail to position movable elements, such as doors or flaps, precisely and efficiently relative to the vehicle body, leading to inconsistent preload and impact absorption.
Innovation Solution
A stop buffer system featuring a receiving sleeve with an elastically deformable buffer and a positioning aid, such as a displaceable pin, L-shaped bracket, or sleeve-shaped measuring cap, allows for exact alignment and adjustment of the buffer relative to the vehicle body, ensuring optimal positioning and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of stop buffer is used, then the stop buffer can be positioned relative to the vehicle body, but the positioning precision is insufficient to maintain structurally specified values
Solution Approach 1:
The patent applies preliminary action by providing predetermined positioning aids (markings, guide elements, or pre-configured positioning features) that enable exact positioning of the stop buffer before final installation. These positioning aids are pre-established on the vehicle body or stop buffer components, allowing the installer to achieve precise alignment without complex measurement or adjustment procedures during assembly.
2Manufacturing precision
If existing stop buffer designs are used, then basic damping function is achieved, but exact positioning and necessary preload cannot be maintained
Solution Approach 1:
The patent introduces positioning aids as intermediary elements that mediate between the stop buffer and the vehicle body. These aids (such as positioning pins, guide slots, or marking systems) serve as intermediaries to transfer and maintain the exact positioning information, enabling precise alignment without requiring complex adjustment mechanisms or sophisticated buffer structures.
3Productivity
If adjustable stop buffers are implemented, then the door or flap can be dampened and fixed in desired position, but the positioning time and assembly complexity increase
Solution Approach 1:
The patent applies self-service by designing the stop buffer with self-positioning capabilities through integrated positioning aids. The buffer automatically aligns with the vehicle body using these aids during installation, eliminating the need for time-consuming manual measurement, marking, or adjustment procedures. The positioning aids guide the buffer into its exact position automatically, making the assembly process faster and more efficient.

AI summary
The invention relates to a bump stop for exactly positioning an element whose position can be changed, such as a door, a lid, or the like on a vehicle body. In order to propose a bump stop that allows the bump stop to be positioned more easily, more quickly, and above all more precisely, it is provided that the bump stop (1) comprises an accommodating sleeve for fixing the bump stop (1) on the body or the element whose position can be changed, that an elastically deformable cushion (3) is supported in the accommodating sleeve (2), the projection of which elastically deformable element above the accommodating sleeve (2) can be adjusted, and that a position aid that allows the element whose position can be changed to be exactly positioned relative to the vehicle body is provided.
