Integrated Front-End Support Structure for Underbody Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle assembly processes are complex and costly due to the proliferation of separate mounts for vehicle components, leading to increased part numbers and difficulty in accessing and replacing components on the front end.
Innovation Solution
A multifunctional support device comprising a cross member and tie rods, which are fixed to the vehicle's cradle and body structure from below, allowing components to be attached from underneath, thereby simplifying assembly and disassembly while reducing part numbers and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate mounts are used to support various components on the front end, then each component can be securely supported, but the number of part numbers increases and assembly costs increase
Solution Approach 1:
The patent combines multiple separate mounts into a single integrated support structure that includes a cross member with multiple tie rods. This unified structure supports multiple components (engine, radiator, bumper) simultaneously, reducing the number of separate parts while maintaining secure support for each component.
Solution Approach 2:
The support structure serves multiple functions: it supports the engine, radiator, and bumper simultaneously; provides attachment points for various components; and enables access to components from below the vehicle. This multi-functionality eliminates the need for separate dedicated mounts for each component.
2Reliability
If multiple separate mounts are used for front end components, then each component has dedicated support, but assembly and disassembly procedures become complex and time-consuming
Solution Approach 1:
By merging multiple separate mounts into one integrated support structure, the assembly process is simplified from multiple separate attachment operations to a single unified installation. This reduces assembly time while maintaining secure support for all components.
Solution Approach 2:
The support structure is designed to be accessed and assembled from below the vehicle, inverting the traditional approach where components are accessed from above or the sides. This inverted access approach simplifies assembly and disassembly procedures by providing clear access to all attachment points.
3Reliability
If multiple separate mounts are used, then component support is provided, but accessibility to components for intervention is reduced
Solution Approach 1:
The support structure is designed with all attachment points accessible from below the vehicle, inverting the traditional arrangement where components are accessed from above or sides. This allows technicians to access and service components without needing to work from above the vehicle, improving ease of operation.
Solution Approach 2:
The support structure creates a three-dimensional arrangement where components are accessible from the vertical dimension (from below), rather than requiring horizontal access from the sides or top. This dimensional change improves accessibility while maintaining secure support.
