Vehicle Sidewall Bracket Structure for Gap Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively and advantageously holding sidewall elements on vehicle bodyshells, particularly in compensating for installation and component tolerances while ensuring a uniform and aesthetically appealing gap size.
Innovation Solution
A multi-part bracket with at least two holding elements, where one element is connected to the bodyshell and the other to the sidewall element, allowing for reversible and adjustable mounting to compensate for tolerances and provide energy dissipation in the event of an accident.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single-part bracket is used to hold the sidewall element, then the structure is simple, but installation and component tolerances cannot be compensated, resulting in non-uniform gap sizes
Solution Approach 1:
The bracket is divided into multiple separate holding elements (first holding element connected to bodyshell, second holding element connected to sidewall element) that can be independently positioned and adjusted. This segmentation allows each element to compensate for tolerances independently, achieving uniform gap sizes while maintaining structural integrity.
2Reliability
If the bracket is rigidly connected to both bodyshell and sidewall element, then structural stability is high, but energy dissipation in the event of accident is limited
Solution Approach 1:
The holding elements are designed with adjustable connection parameters that allow them to transition from a rigid state during normal operation to a deformable state during accidents. The connections can be configured to allow controlled deformation, enabling energy dissipation while maintaining structural stability under normal conditions.
3Manufacturing precision
If multiple holding elements are used to compensate for tolerances, then gap uniformity is improved, but the number of components and assembly complexity increases
Solution Approach 1:
The multiple holding elements are designed as universal components that perform multiple functions: they provide structural support, enable tolerance compensation through adjustable positioning, and facilitate reversible mounting. This multi-functionality reduces the need for specialized components, simplifying manufacturing and assembly processes.
4Ease of repair
If the mounting is made reversible and adjustable for tolerance compensation, then ease of repair and adjustment is improved, but structural strength may be reduced
Solution Approach 1:
The mounting system incorporates dynamic characteristics that allow it to adapt between reversible/adjustable states and rigid/strong states. The holding elements can be easily positioned and adjusted during assembly to compensate for tolerances, while their structural design ensures they provide sufficient strength when properly installed. The system transitions from an adjustable configuration during assembly to a stable configuration during operation.

AI summary
An arrangement for holding a sidewall element on a bodyshell part of a bodyshell for a vehicle, in which arrangement the sidewall element is held on the bodyshell part by way of a bracket which is formed separately from the bodyshell part and separately from the sidewall element. The bracket is connected to the bodyshell part and to the sidewall element, wherein the bracket has a first retaining element connected to the bodyshell part and a second retaining element, which is connected to the sidewall element and is formed separately from the first retaining element and is connected to the first retaining element.
