Integrated Wheel House Reinforcement Structure for Vehicle Body Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel house structures in vehicles have insufficient connectivity between the quarter part, shock absorber part, and trunk lid, leading to increased weight, manufacturing costs, and complexity in assembly, while also compromising stiffness and NVH performance.
Innovation Solution
An integrated wheel house reinforcement structure that includes a mounting part, a cover part, and a trunk lid mounting part, featuring ribs and flanges for enhanced stiffness, with the quarter panel, shock absorber, and trunk lid being integrally mounted to improve connectivity and reduce weight and assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate panels are configured for quarter part, shock absorber part, and trunk lid, then ease of manufacture is improved, but weight increases and manufacturing cost increases
Solution Approach 1:
The patent merges the quarter part, shock absorber part, and trunk lid into a single integrated wheel house structure. This consolidation eliminates the need for separate panels and their associated fastening components, thereby reducing overall weight while maintaining manufacturing feasibility through unified production processes.
2Ease of manufacture
If separate panels are configured for quarter part, shock absorber part, and trunk lid, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple separate components (quarter part, shock absorber part, trunk lid) into one integrated structure. This reduces device complexity by eliminating the need for multiple fastening operations, alignment procedures, and assembly steps, while the unified design simplifies manufacturing processes.
3Ease of manufacture
If separate panels are configured for quarter part, shock absorber part, and trunk lid, then ease of manufacture is improved, but mounting time increases
Solution Approach 1:
The patent integrates the quarter part, shock absorber part, and trunk lid into a single pre-assembled unit that can be mounted as one component. This eliminates the time required for multiple separate mounting operations, alignment, and fastening, thereby reducing total mounting time while maintaining ease of manufacture through unified production.
4Ease of manufacture
If separate panels are configured for quarter part, shock absorber part, and trunk lid, then ease of manufacture is improved, but connectivity is insufficient
Solution Approach 1:
The patent merges the quarter part, shock absorber part, and trunk lid into a single integrated structure with continuous material flow. This eliminates joint connections between separate panels, thereby improving connectivity and structural reliability while maintaining ease of manufacture through unified production processes.
5Reliability
If integrated structure is used for wheel house, then connectivity is improved and weight is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent segments the integrated wheel house structure into modular sections that can be manufactured separately and then assembled. This segmentation approach maintains the connectivity benefits of an integrated design while reducing manufacturing complexity by allowing parallel production and simplified assembly operations.
