Vehicle Dash Reinforcement Layout for Front Apron Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dash lower reinforcement panel in vehicles is insufficient in supporting the front apron and does not effectively disperse the load, particularly in vehicles with skateboard frames where the front apron cannot extend to the lower dash, necessitating a reinforcement configuration.
Innovation Solution
A front structure for a vehicle body incorporating a dash reinforcement unit with longitudinal and transverse members, a chassis frame, and a fender apron reinforcement member to enhance the strength and stability of the dash panel, allowing for flexible design modifications and load dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the existing dash lower reinforcement panel configuration is used, then the structure is simple, but the dash panel strength is insufficient and cannot effectively support the front apron
Solution Approach 1:
The reinforcement structure is divided into multiple independent members including longitudinal members (first longitudinal member, second longitudinal member), transverse members (first transverse member, second transverse member, third transverse member), and diagonal members. Each member is separately positioned and connected to the dash panel at specific locations to provide distributed structural support and effectively disperse loads across the panel.
Solution Approach 2:
The reinforcement structure incorporates members extending in multiple dimensions: longitudinal members extend in the length direction, transverse members extend in the width direction, and diagonal members provide cross-directional support. This multi-dimensional arrangement creates a comprehensive reinforcement network that strengthens the dash panel from multiple structural perspectives simultaneously.
2Adaptability or versatility
If the front apron cannot extend to the lower dash due to skateboard frame, then the vehicle design flexibility is maintained, but the load support capability is reduced
Solution Approach 1:
The reinforcement members are pre-positioned and connected to the dash panel before final assembly, creating a prepared load-bearing framework. The longitudinal, transverse, and diagonal members are arranged in advance to form a structural network that is ready to receive and distribute loads from the front apron and other vehicle components.
Solution Approach 2:
The reinforcement members act as intermediary structural elements between the dash panel and the front apron. When the front apron cannot directly extend to the lower dash due to skateboard frame constraints, these intermediary members transmit and distribute the loads through the dash panel, enabling load support capability while maintaining design flexibility.
3Force
If one member responds to the rolling load of the vehicle body, then the structure is simple, but the load dispersion is insufficient
Solution Approach 1:
The load response function is segmented across multiple members including longitudinal members, transverse members, and diagonal members. Each member is positioned to handle specific portions of the rolling load, with longitudinal members carrying loads in the length direction, transverse members in the width direction, and diagonal members providing cross-directional load distribution.
Solution Approach 2:
Multiple reinforcement members are combined to work together as an integrated load-bearing system. The longitudinal, transverse, and diagonal members are connected to the dash panel and to each other, creating a unified structural network that collectively responds to and disperses rolling loads more effectively than any single member could alone.
