Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road utility vehicles require versatile configurations to support various accessories and loads, but existing designs lack efficient mounting systems for heavy loads and cargo transport, especially in off-road terrain.
Innovation Solution
A utility vehicle design featuring a robust frame assembly with multiple mounting locations for a suspension assembly, differential, steering mechanism, and tie-down members, along with a hydraulic system to adjust suspension height, enabling secure load support and cargo transport across diverse terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mounting locations are added to support various accessories and heavy loads, then the vehicle's versatility and load-bearing capability are improved, but the frame assembly complexity increases
Solution Approach 1:
The frame assembly is designed with multiple mounting locations that can serve various functions - supporting suspension assemblies, differentials, steering mechanisms, tie-down members for cargo, and accessory mounts. This multi-functional design allows a single frame structure to accommodate diverse configurations for different applications including heavy load towing, cargo transport, and accessory installation, thereby achieving versatility without proportionally increasing complexity
Solution Approach 2:
The frame assembly is divided into distinct sections with specific mounting locations strategically positioned for different components. Each mounting location is designed as a separate attachment point that can be independently configured, allowing the frame to be adapted for various purposes while maintaining structural integrity and managing complexity through modular design
2Quantity of substance
If a cargo platform is positioned to extend over the seat harness for maximum cargo capacity, then the cargo transport capability is improved, but the operator safety and comfort deteriorate
Solution Approach 1:
The cargo platform is designed with adjustable positioning capability, allowing it to be moved between different locations including positions that extend over the seat harness for maximum cargo capacity and positions that clear the operator area for enhanced safety and comfort. This dynamic repositioning feature enables the system to adapt to different operational requirements, balancing cargo capacity needs with operator safety concerns
3Adaptability or versatility
If the seat harness is made movable between positions, then the adaptability for different cargo configurations is improved, but the structural complexity of the seat harness increases
Solution Approach 1:
The seat harness is designed as a movable component that can be repositioned between different locations along the frame assembly. This dynamic positioning capability allows the harness to adapt to various cargo configurations and operator positioning needs, providing versatility in how cargo and operators are arranged while maintaining a relatively simple implementation through guided movement along predefined paths or rails

AI summary
A utility vehicle is configured for off-road terrain and may include a plurality of mounting members configured to support a load and/or support the vehicle during transport. The utility vehicle also includes an upper frame assembly which is movable between a first position and second position. The upper frame assembly may be moved to the second position during transportation of the utility vehicle. Further, the utility vehicle includes a plurality of configurations for a rear cargo area, thereby allowing for passengers or cargo to be supported.
