Off-Road Vehicle Upper Frame with Forward Bends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road utility vehicles require a frame that can support additional cab components such as windshields, roofs, and doors, while maintaining structural integrity and passenger safety over varied terrains.
Innovation Solution
A frame assembly with longitudinally extending frame members featuring bends positioned forward of the seating area, providing additional support and strength to accommodate these components without compromising visibility or structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame members are made longer and more complex to support additional cab components, then the support capability and versatility are improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The frame members are divided into multiple segments with distinct bends (first bend, second bend, third bend) positioned at specific locations. Each segment serves a specific structural function, allowing the frame to support various cab components while maintaining manageable complexity through modular segmentation.
Solution Approach 2:
The frame members incorporate multiple bends in different spatial dimensions (longitudinal, lateral, and vertical bends) to create a three-dimensional support structure. This dimensional approach enables the frame to accommodate windshields, roofs, and doors without requiring excessive length or material.
2Strength
If the frame members include multiple bends to support cab components, then the structural strength and support capability are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The frame members are designed with specific bend radii and angles as standardized parameters. The first bend has a predetermined radius, the second bend has a specific angle, and the third bend connects to the lateral frame member at a defined angle. These standardized parameters simplify manufacturing while ensuring consistent structural strength.
Solution Approach 2:
Different sections of the frame members have different geometric properties tailored to their specific functions. The bends are positioned at specific locations with specific radii and angles to optimize strength where needed while maintaining ease of manufacture. Each local region of the frame member has quality characteristics optimized for its particular structural role.

AI summary
An upper frame portion of a frame of a vehicle includes a first longitudinal frame member having a first end and a second end and a second longitudinal frame member having a first end and a second end. The first longitudinal member and the second longitudinal member each include a first end and a second bend. The first bends and the second bends are positioned adjacent one another and forward of a seating area.
