Side-by-Side Utility Vehicle Frame Rigidity and Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current side-by-side utility vehicles lack enhanced structural rigidity and passenger safety features, and there is a need for improved seating arrangements and powertrain configurations to accommodate multiple passengers and cargo effectively across various terrains.
Innovation Solution
The design incorporates a robust frame with cross-members for increased rigidity, a powertrain assembly with an engine and transmission, and a seating arrangement for at least two passengers in a side-by-side configuration, along with a roll cage assembly and air intake system, supported by a frame that includes a hood, side panels, and a dashboard assembly, enhancing structural integrity and passenger safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a robust frame with cross-members is incorporated, then structural rigidity is improved, but device complexity increases
Solution Approach 1:
The frame is divided into multiple cross-members that segment the frame structure into rigid sections. These cross-members are positioned at strategic locations to provide structural support and rigidity while maintaining manufacturability through modular construction.
2Reliability
If a roll cage assembly is added, then passenger safety is improved, but device complexity increases
Solution Approach 1:
The roll cage assembly is integrated with the frame structure, merging the safety function into the existing structural framework. This combination provides passenger protection while avoiding the need for completely separate structural systems.
3Reliability
If seating for multiple passengers in side-by-side arrangement is provided, then passenger capacity and safety are improved, but device complexity increases
Solution Approach 1:
The seating structure serves multiple functions: it provides side-by-side seating for multiple passengers, integrates with the roll cage for safety, and incorporates seat belts and restraint systems. This multi-functionality reduces the need for separate safety components.
4Productivity
If a powertrain assembly with engine and transmission is incorporated, then power delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The powertrain assembly merges the engine and transmission into an integrated unit that is directly coupled to the ground engaging members. This integration streamlines power delivery while reducing the number of separate components and connections required.
