Micro Vehicle Damper Housing Structure for Higher Mounting Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micro vehicles suffer from poor connectivity between front and rear damper housings, leading to disconnected pairs of front and rear dampers, which affects mounting stiffness and overall vehicle stability.
Innovation Solution
A micro vehicle design with a chassis frame structure that includes reinforced damper mounting panels and bosses, featuring embedded reinforcing members and ribs to enhance connectivity and stiffness between front and rear dampers, thereby improving mounting stability and reducing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a pair of front damper housings and a pair of rear damper housings are used in existing micro vehicles, then the dampers can be mounted, but the connectivity between the pair of front dampers and the pair of rear dampers is poor, resulting in disconnected pairs and reduced mounting stiffness
Solution Approach 1:
The patent merges the previously separate front and rear damper housings into a single integrated damper housing structure. This unified housing provides continuous structural support across the vehicle width, eliminating the disconnection between left and right dampers and significantly improving both mounting stiffness and structural connectivity.
Solution Approach 2:
The integrated damper housing is segmented into functional regions (front damper mounting area, rear damper mounting area, and connecting structure) that work together as a unified system. This segmentation allows optimized mounting points while maintaining overall structural connectivity.
2Ease of manufacture
If multiple separate damper housing components are used, then assembly flexibility is maintained, but the number of components increases and manufacturing complexity rises
Solution Approach 1:
By combining multiple separate damper housing components into a single integrated housing, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This consolidation simplifies the supply chain and manufacturing processes while lowering overall production costs.
Solution Approach 2:
The integrated damper housing serves multiple functions simultaneously: it houses both front and rear dampers, provides structural support, ensures connectivity between dampers, and reduces component count. This multi-functionality eliminates the need for separate housings for each damper.
3Stability of the object's composition
If traditional disconnected damper housing design is used, then manufacturing is simpler for each individual component, but the overall vehicle stability and static stiffness are reduced
Solution Approach 1:
The integration of front and rear damper housings into a single continuous structure creates a unified load-bearing system that improves both vehicle stability and static stiffness. The continuous housing structure distributes and manages forces more effectively across the entire vehicle width.
