Off-Road Vehicle Frame With HVAC Tunnel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles lack effective enclosures to protect occupants from elements, and existing frames are often single-purpose, failing to adapt to different applications, with inadequate temperature regulation.
Innovation Solution
A modular frame design for off-road vehicles that includes a tunnel structure supporting HVAC components, allowing for partial enclosure and adaptable design elements such as monocoque construction, removable panels, and integrated mounting points for various systems, enabling better protection and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-purpose frame is used, then the frame structure is simple, but the adaptability to different vehicle applications is poor
Solution Approach 1:
The frame is designed with universal mounting points and standardized interfaces that allow different body styles, HVAC systems, and accessories to be attached to the same frame structure, enabling one frame to serve multiple vehicle applications
Solution Approach 2:
The frame incorporates modular components and standardized mounting sections that can be configured differently for various applications, allowing the frame to be adapted without redesigning the entire structure
2Object-affected harmful factors
If body panels are added to enclose occupants, then protection from elements is improved, but the enclosure becomes too hot or cold
Solution Approach 1:
HVAC components are introduced as intermediary systems between the enclosed space and the external environment, actively regulating temperature to counteract the greenhouse effect created by body panels
Solution Approach 2:
The HVAC system extracts heat from the enclosed space during hot conditions and adds heat during cold conditions, removing the temperature extremeness caused by full enclosure
3Temperature
If HVAC components are integrated into the frame, then temperature regulation is improved, but the frame complexity increases
Solution Approach 1:
HVAC mounting tunnels and support structures are merged directly into the frame construction, combining the structural support function with the HVAC integration function into a single unified structure
Solution Approach 2:
The frame incorporates standardized HVAC mounting sections that serve dual purposes as both structural elements and HVAC system supports, reducing overall complexity through multi-functionality

AI summary
A vehicle shown herein is a side by side utility vehicle having a frame, front and rear ground engaging members supporting the frame, a powertrain drivingly coupled to the front and rear ground engaging members, and a seating area supported by the frame. The frame can include a tunnel extending longitudinally through at least a portion of the seating area, and the tunnel supports one or more HVAC components.
