Multi-Row Utility Vehicle Seating Layout for Low Center of Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional all-terrain vehicles (ATVs) and utility vehicles typically accommodate only one or two passengers and limited cargo, lacking the ability to comfortably seat multiple passengers while maintaining a low center of gravity and providing adequate cargo space, especially when customized with additional seating.
Innovation Solution
A utility vehicle design featuring a frame with a drive train and multiple wheels, including a first and second seating area positioned longitudinally, where the second seating area has a higher hip pivot axis and is positioned rearward, with a roll cage and hand hold bar for enhanced safety and ergonomics, and a frame tube coupler system for structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a second row of seats is added to conventional ATVs, then passenger capacity is increased, but the center of gravity rises and vehicle stability deteriorates
Solution Approach 1:
The patent positions the second row of seats longitudinally forward of the rear axle centerline, rather than directly behind it. This longitudinal repositioning in the forward direction allows the second row to contribute to forward weight distribution, maintaining a lower overall center of gravity and improving vehicle stability while still accommodating additional passengers
Solution Approach 2:
The patent creates different seating heights between the first and second rows, with the second row positioned at a higher hip pivot axis. This local differentiation in seating quality allows the second row passengers to have improved visibility and ergonomics while the overall vehicle center of gravity remains controlled through strategic positioning
2Quantity of substance
If the second seating area is positioned rearward for cargo space, then cargo capacity is improved, but passenger ergonomics and safety are worsened
Solution Approach 1:
The patent repositions the second seating area from a purely rearward location to a location that is longitudinally forward of the rear axle centerline. This dimensional shift in the longitudinal axis creates space for both adequate cargo capacity behind the second row and improved passenger ergonomics with the second row positioned forward where it can contribute to stable weight distribution
3Ease of operation
If seating areas are positioned to maximize passenger comfort, then ergonomics are improved, but cargo space is reduced
Solution Approach 1:
The patent clearly segments the vehicle into distinct functional zones: the first row for primary passengers, the second row positioned forward of the rear axle for secondary passengers with good ergonomics, and the area behind the second row for cargo. This segmentation allows each zone to be optimized for its specific function without compromising the others
Solution Approach 2:
By positioning the second row forward of the rear axle centerline rather than directly behind it, the patent creates additional longitudinal space behind the second row for cargo while maintaining adequate headroom and legroom for second row passengers through the higher hip pivot axis positioning
