Height-Adjustable Buffer Element for Vehicle Hood Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffer elements for motor vehicle hoods are prone to inaccurate height adjustment, leading to noise and damage due to metal components causing rattling and potential disengagement during operation, which compromises safety and reliability.
Innovation Solution
A buffer element with a separated fastening and buffering effect, utilizing a soft plastic or rubber buffer that is adjustable and lockable, ensuring precise positioning and secure attachment to the fastening element, thereby preventing unintended disengagement and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded bolt is used as a spacer and stop for a movable body part, then height adjustment is possible, but the body part lies directly on the metal threaded bolt causing rattling noises and damage
Solution Approach 1:
A soft buffer element is introduced as an intermediary between the metal threaded bolt and the body part. The buffer element comprises a soft buffer body that contacts the body part, eliminating direct metal-to-metal contact and preventing rattling noises and damage while still allowing height adjustment through the threaded bolt mechanism.
2Adaptability or versatility
If the threaded bolt is pivoted into an internal thread for height adjustment, then position adjustment is possible, but the threaded bolt may suddenly disengage during operation due to unforeseen forces
Solution Approach 1:
The buffer element is segmented into distinct functional parts: a fastening element (threaded bolt) for height adjustment and a separate buffer body for cushioning and protection. This segmentation allows the fastening mechanism to be optimized for adjustability while the buffer body provides reliable protection against disengagement by absorbing forces that could cause the threaded bolt to pivot back.
3Ease of manufacture
If the buffer element is designed as a single integrated unit, then assembly is simple, but precise height adjustment and secure buffering are compromised
Solution Approach 1:
The buffer element is divided into separate components: a fastening element and a buffer body. The fastening element can be precisely adjusted and locked at the desired height position, while the buffer body is separately optimized for cushioning performance. This segmentation enables both precise height adjustment and secure buffering, with the components working together as a coordinated system.

AI summary
A buffer element is proposed for use as a stop for a movable part, in particular a front or rear hood of a motor vehicle, on a supporting part, in particular a body, comprising a fastening element (1) that can be fixed to the supporting or movable part, and a buffer (2) that is held directly or indirectly by the fastening element (1), wherein the buffer (2) is height-adjustable relative to the fastening element (1). The buffer element according to the invention is easy to install and enables safe operation while simultaneously offering improved functionality compared to the prior art.
