UTV Door and Window Assembly Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility all-terrain vehicles (UTVs) lack comprehensive protection for passengers from elements and debris due to partially extended doors that do not seal the vehicle's openings effectively.
Innovation Solution
A door and window assembly system that pivots and rotates to fully seal the vehicle's openings, with the door and window assembly working together to provide complete closure and protection when in closed positions, utilizing a coupling mechanism and movement mechanism like hydraulic or pneumatic cylinders for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a door is mounted to the chassis to protect passengers, then passenger protection is improved, but the door extends over only a portion of the height of the vehicle and fails to protect passengers from elements and debris
Solution Approach 1:
The door assembly is divided into two functional segments: a lower door portion and an upper window assembly portion. The lower door provides structural support and access, while the upper window assembly extends the protective coverage to the top of the opening. This segmentation allows each component to be optimized for its specific function while together they provide comprehensive protection against elements and debris.
Solution Approach 2:
The window assembly is configured to rotate about a horizontal axis, adding a rotational dimension to the door system. This allows the window assembly to move independently from the lower door, enabling the upper portion to be opened or closed separately. This dimensional change provides flexible protection coverage while maintaining comprehensive sealing when both components are closed.
2Object-affected harmful factors
If a door and window assembly system is used to seal the opening completely, then protection from elements and debris is improved, but the device complexity increases
Solution Approach 1:
The lower door and upper window assembly are merged into a single integrated door assembly system. The window assembly is directly coupled to the roll cage, and the lower door is positioned adjacent to it, creating a unified protective structure. This merging provides comprehensive sealing of the opening while using simple, straightforward mechanical connections rather than complex multi-component systems.

AI summary
A utility terrain vehicle is provided including a vehicle body having an opening. A door is positioned adjacent a first portion of said opening. The door is configured to pivot about a first axis between an open position and a closed position. A window assembly is arranged adjacent a second portion of said opening. The window assembly is rotatable about a second axis between an open position and a closed position. In combination, the door and the window assembly substantially seal said opening of the vehicle body when said door is in said closed position and said window assembly is in said closed position.
