Side-by-Side ATV Trail Width Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side-by-side all-terrain vehicles (ATVs) exceed the maximum trail width requirement of 50 inches, making them impractical for recreational trail riding on public lands due to their width of at least 54 inches, which causes environmental damage.
Innovation Solution
Designing an ATV with a frame, front and rear suspension systems, and a modular engine assembly that positions the engine rearward of the seating area, featuring a continuously variable transmission and a protective cage, while maintaining a width of less than 54 inches by optimizing the wheelbase and seat height ratio, and strategically placing components like the fuel tank and battery to lower the center of gravity and improve ergonomics and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If side-by-side seating arrangement is used, then passenger viewing experience is improved, but vehicle width increases beyond trail limits
Solution Approach 1:
The patent changes the geometric parameters of the vehicle by reducing the wheelbase length and optimizing the seat height ratio. This allows the side-by-side seating arrangement to be maintained while the overall vehicle width is reduced to meet the 50-inch trail limit, resolving the contradiction between passenger viewing experience and vehicle width compliance
2Stability of the object's composition
If wider vehicle design is used, then stability is improved, but trail compliance is violated
Solution Approach 1:
The patent achieves trail compliance by reducing the vehicle width parameter to meet the 50-inch limit while compensating for stability through optimized weight distribution and center of gravity positioning. The reduced width prevents environmental damage on trails while maintaining vehicle stability through proper component placement and suspension geometry
