Adjustable bracket for installation of a vehicle bumper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle bumper brackets are one-piece structures that lack adjustability, making it difficult to achieve a precise match between the bumper skin and vehicle lights, as they cannot be easily deformed to adjust clearance.
Innovation Solution
An adjustable bracket system comprising a fixed bracket and an adjusting bracket with a movable connection, allowing vertical translation and position-limiting features to ensure optimal clearance between the bumper skin and lights, utilizing cross ribs and position-limiting pins for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a one-piece structured bracket is used to increase strength and ensure supporting effect, then the bracket strength is improved, but the adjustability of the bracket is worsened
Solution Approach 1:
The bracket is divided into two separate parts: a fixed bracket and an adjusting bracket. The fixed bracket provides structural strength and support, while the adjusting bracket enables clearance adjustment between the bumper skin and light. This segmentation allows each part to fulfill its specific function without compromising the other.
2Stability of the object's composition
If a one-piece structured bracket is used to ensure structural integrity, then the structural stability is improved, but the ease of adjustment is worsened
Solution Approach 1:
The bracket system is segmented into a fixed bracket that remains stable and an adjusting bracket that can be independently positioned. The fixed bracket maintains structural integrity when mounted to the vehicle body, while the adjusting bracket can be freely adjusted vertically to achieve the desired clearance before being fixed in place.
Solution Approach 2:
The adjusting bracket is designed to be dynamically adjustable relative to the fixed bracket through a movable connection mechanism. This allows the adjusting bracket to be repositioned vertically to control clearance, and then fixed in the desired position, combining dynamic adjustability with static stability.
3Ease of manufacture
If the bracket is made as a one-piece structure to simplify manufacturing, then the manufacturing complexity is reduced, but the clearance adjustment capability is worsened
Solution Approach 1:
The bracket is manufactured as two separate components that can be produced using standard manufacturing processes. The fixed bracket and adjusting bracket are each manufactured independently with standard tolerances, then assembled together. The adjusting bracket's ability to move vertically allows for precise clearance adjustment during installation without requiring high-precision manufacturing of the entire bracket as a single piece.

AI summary
An adjustable bracket for installation of a vehicle bumper on a body of a vehicle is provided. The bracket is configured to be connected to the body to support the bumper, characterized in that the bracket includes a fixed bracket and an adjusting bracket, wherein the bracket has a movable connection between the fixed bracket and the adjusting bracket, which allows the adjusting bracket to have a translational movement in the vertical direction of the vehicle with respect to the fixed bracket, and wherein the adjusting bracket is provided at its top with position-limiting means which can abut against a light of the vehicle, and wherein the fixed bracket and the adjusting bracket are both provided with a mounting structure fastened to the same body. The adjustable bracket enables the bumper to be vertically positioned by the adjusting bracket, which controls the matching clearance between the bumper and the light, thereby effectively reducing the risks of uneven match between the light and the bumper.
