Side-by-Side Vehicle Layout for a Lower Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-terrain and utility vehicles face challenges in maintaining stability on rugged terrain due to high centers of gravity, which can compromise their performance and safety.
Innovation Solution
The vehicle design incorporates lightweight components and strategically positions heavier components lower on the vehicle to lower the center of gravity, utilizing a frame assembly with a powertrain assembly, suspension systems, and a cab frame assembly made from lighter materials such as aluminum and carbon fiber to achieve a stable and balanced configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If heavier components are positioned lower on the vehicle, then stability is improved, but weight distribution complexity increases
Solution Approach 1:
The patent addresses stability by transitioning from horizontal weight distribution to vertical weight distribution. Heavier components (engine, transmission, battery) are positioned lower in the vertical dimension of the vehicle, lowering the center of gravity and improving stability on rugged terrain without significantly increasing design complexity
Solution Approach 2:
The patent uses composite material construction (aluminum frame assembly combined with lighter cab frame materials) to achieve optimal weight distribution. The heavier aluminum frame provides structural support and houses heavy components lower down, while lighter materials are used for the cab frame to reduce overall weight while maintaining the lowered center of gravity configuration
2Weight of moving object
If lightweight materials are used for frame assemblies, then center of gravity is lowered, but structural strength may be compromised
Solution Approach 1:
The patent employs composite material construction where the frame assembly uses aluminum (lighter than traditional steel) while the cab frame uses even lighter materials. This multi-material approach reduces overall weight and lowers the center of gravity while maintaining structural strength through careful material selection and structural design
Solution Approach 2:
Different materials are applied to different parts of the vehicle structure based on local requirements. The aluminum frame assembly provides structural strength where needed, while lighter materials are used for the cab frame where weight reduction is prioritized. This localized material quality optimization balances weight reduction with structural strength requirements
