Roll Cage Air Delivery for Dust-Free Helmet Breathing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Occupants of all-terrain vehicle passenger compartments are exposed to unhealthy outside air containing dust and particulates, leading to breathing difficulties and discomfort during vehicle use, especially in vehicles with open compartments or roll-over protection structures.
Innovation Solution
An air delivery system is integrated into the vehicle's roll-over protection structure, utilizing an air pump and conduits to provide filtered air directly to wearables like helmets through a network of structural tubing forming part of the roll cage, ensuring a clean breathing environment for occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the passenger compartment is kept open for ventilation, then air circulation is improved, but occupants are exposed to dust and airborne particulates
Solution Approach 1:
The air delivery system segments the air supply by providing separate clean air sources to each occupant through individual conduits and outlets positioned near helmets, allowing selective delivery of filtered air to specific locations while maintaining overall compartment ventilation
Solution Approach 2:
The system introduces an intermediary air delivery mechanism between the external environment and occupants, using conduits routed through the roll cage structure to transport filtered air from the air source to outlets positioned near each occupant's helmet, effectively mediating the harmful exposure while maintaining ventilation benefits
2Reliability
If a roll over protection structure is installed to protect occupants, then safety is improved, but the structure does not provide filtered air delivery
Solution Approach 1:
The roll over protection structure is enhanced with multi-functionality by integrating air delivery conduits within the existing roll cage tubing, allowing the protective structure to simultaneously serve as both safety protection and filtered air delivery system, eliminating the need for separate ventilation components
Solution Approach 2:
The system merges the safety function of the roll cage with the air delivery function by routing conduits through the existing structural tubing of the roll over protection structure, combining two separate systems into one integrated solution that provides both protection and breathable air
3Volume of moving object
If conduits are routed through the roll cage structure for air delivery, then space is utilized efficiently, but the system complexity increases
Solution Approach 1:
The air delivery conduits are merged with the existing roll cage structure by routing them through the available space within the structural tubing, combining the air delivery function with the existing safety structure rather than adding separate external ducting systems
Solution Approach 2:
The roll cage structure serves multiple functions by housing both its protective structural role and the air delivery conduit pathway, making the existing structure universal for both safety and ventilation purposes, thereby avoiding additional structural additions

AI summary
A vehicle includes a body mounted with a chassis, the body having a passenger compartment, a seat in the passenger compartment for supporting an occupant in a sitting position, and a roll over protection structure for the passenger compartment. The roll over protection structure includes an inlet coupled in gaseous communication to an air source, an outlet coupled in gaseous communication to a vehicle occupant wearable, and an airflow pathway through the roll over protection structure coupling the inlet to the outlet in gaseous communication.
