Wheel Housing Liner Bracket Resilient Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel housing liner assemblies lack effective support for the upper section of the liner, leading to potential sagging due to material degradation from environmental factors and debris impact, which can result in contact with the wheel and increased noise.
Innovation Solution
A liner supporting bracket with a first portion attached to the inboard panel, a second portion attached to the outboard fender panel, and a main portion that extends to support the upper section of the liner, providing additional rigidity and preventing sagging through mechanical fasteners and resilient clamping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liner is made from inexpensive materials like recycled plastic or polymer, then the manufacturing cost is reduced, but the liner sags and degrades due to environmental factors and debris impact
Solution Approach 1:
The patent combines inexpensive liner materials (recycled plastic or polymer) with a metal bracket structure to create a composite assembly. The metal bracket provides the structural strength and durability needed to resist degradation and sagging, while the inexpensive liner material maintains low manufacturing cost. This composite approach allows each material to perform its optimal function.
Solution Approach 2:
The metal bracket acts as an intermediary structural element between the wheel housing structure and the inexpensive liner material. It provides mechanical support and distributes loads, preventing the liner from sagging or deforming under environmental stress and debris impact, thereby enhancing overall reliability without increasing liner material cost.
2Device complexity
If the liner is supported without additional brackets, then the device complexity is reduced, but the upper section of the liner sags and contacts the wheel
Solution Approach 1:
The support structure is segmented into distinct functional portions: a first portion that attaches to the wheel housing structure, a second portion that attaches to the fender panel, and a main portion that directly supports the liner. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity and preventing liner sagging.
Solution Approach 2:
The bracket extends in multiple dimensions within the wheel housing structure, creating a three-dimensional support framework. By utilizing vertical and horizontal spacing, the bracket provides multi-point support for the liner, effectively preventing sagging without requiring excessive structural complexity.
3Object-generated harmful factors
If resilient materials and clamping mechanisms are added to the bracket, then noise reduction is improved, but the device complexity increases
Solution Approach 1:
The patent incorporates resilient materials into the bracket structure, which act as flexible damping elements. These resilient portions absorb vibrations and reduce noise transmission from the wheel area to the wheel housing structure, while maintaining the overall simplicity of the bracket design through integrated rather than separate components.
