ATV Cabin Dashboard Segmentation for Passenger Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In all terrain vehicles where three passengers are seated side by side, the existing dashboard configuration does not effectively restrict forward movement of passengers, especially when wheel wells obstruct foot placement, leading to discomfort and reduced ride quality.
Innovation Solution
A cabin space structure with a dashboard divided into left, right, and central portions, where the left and right portions are positioned rearward of the wheel wells to restrict forward movement, and the central floor is elevated to accommodate an intake passage, ensuring comfortable seating for all passengers, including a pedal placement that allows leg space adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If seats are arranged to accommodate three passengers side by side, then passenger capacity is improved, but dashboard shape optimization becomes difficult due to wheel well obstructions
Solution Approach 1:
The dashboard is divided into a left-side portion, a right-side portion, and a vehicle-width-directionally central portion. This segmentation allows each portion to be independently positioned relative to the wheel wells, enabling the side portions to be disposed on the rear side of the wheel wells while the central portion can be optimized for passenger comfort and accessibility.
2Length of moving object
If wheel wells project rearwardly to accommodate front wheels, then wheel clearance is improved, but foot placement space for passengers is obstructed
Solution Approach 1:
The dashboard's left-side and right-side portions are positioned in the longitudinal dimension (rearward direction) relative to the wheel wells, rather than attempting to resolve the conflict in the lateral dimension. This dimensional shift allows the wheel wells to maintain their rearward projection for adequate wheel clearance while the dashboard portions are disposed on the rear side of the wheel wells to provide foot placement space.
3Reliability
If dashboard is positioned to restrict forward movement of passengers, then safety is improved, but leg space for passengers is reduced
Solution Approach 1:
The dashboard is segmented into side portions and a central portion, with the side portions positioned rearward of the wheel wells. This segmentation creates distinct functional zones: the side portions restrict forward movement for safety while the space between the wheel wells and central floor is preserved for leg space and pedal accommodation.

AI summary
A cabin space structure for an all terrain vehicle that enables optimization of the shape of a dashboard in the case where seats are so arranged that three persons can be seated side by side in the vehicle width direction. The cabin space structure includes seats on which three passengers are seated side by side in the vehicle width direction, a step floor on which the passengers seated on the seats place their feet, wheel wells for left and right front wheels, the wheel wells provided to project rearwardly at a left-side portion and a right-side portion of the step floor and the dashboard disposed forwardly of the seats. The dashboard is adapted to restrict forward movement of the passengers seated on the seats. A left-side portion and a right-side portion of the dashboard are disposed on the rear side relative to a vehicle-width-directionally central portion of the dashboard.
