Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing off-road vehicles lack an efficient and innovative frame design that effectively supports electric power storage and propulsion systems, particularly in terms of battery assembly and electric propulsion motor placement.
Innovation Solution
The off-road vehicle frame is designed with a main frame section that supports a battery assembly at the front and an electric propulsion motor at the rear, with specific subsections for each component to optimize space and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery assembly is positioned at the front of the off-road vehicle, then the electric propulsion motor can be positioned at the rear, but this may affect the vehicle's center of gravity and weight distribution
Solution Approach 1:
The frame is divided into a main frame section and subsections, with the battery assembly mounted on a front subsection and the electric propulsion motor mounted on a rear subsection. This segmentation allows independent positioning of heavy components to achieve both ergonomic accessibility and stable weight distribution.
2Productivity
If specific subsections are added to the frame for component support, then component placement is optimized, but the frame structure becomes more complex
Solution Approach 1:
The subsections of the frame serve multiple functions: they provide structural support for the battery assembly and electric propulsion motor, define mounting positions for optimal propulsion efficiency, and maintain overall frame integrity. This multi-functionality reduces the need for additional specialized components.
3Volume of moving object
If the battery assembly is positioned closer to the front than the electric propulsion motor, then space utilization is improved, but this may affect the vehicle's balance
Solution Approach 1:
The frame design employs asymmetric positioning of components, with the battery assembly mounted on a front subsection and the electric propulsion motor on a rear subsection. This asymmetric arrangement optimizes space utilization while the specific positioning maintains vehicle balance through strategic weight distribution.
