Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open-air vehicle cooling systems are ineffective in humid environments and lack a payment system for users to activate cooling services, making them uncomfortable in hot and humid climates and not economically viable for widespread adoption.
Innovation Solution
A portable cooling system for open-air vehicles that integrates a fan and a payment system, utilizing a pressurized accumulator to provide a steady mist flow, adjustable mist nozzles, and a card reader/display unit for payment authorization, allowing users to control the cooling system's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a known misting system is used in dry environments, then cooling effectiveness is improved, but it does not work well in humid environments
Solution Approach 1:
The system dynamically adjusts between misting mode and fan mode based on environmental conditions. The controller activates the misting system when humidity is low and switches to fan-only mode when humidity is high, allowing the system to adapt to varying environmental conditions and maintain cooling effectiveness across different climates
2Area of stationary object
If a stationary misting apparatus is used for cooling large areas, then cooling coverage is improved, but the system requires a large water source and pumping system making it non-portable
Solution Approach 1:
The invention extracts and removes the complex stationary pumping system from the cooling apparatus. Instead of using a large stationary pump, the system uses a portable pump integrated into the vehicle-mounted cooling unit, allowing the system to be moved and deployed flexibly without requiring fixed infrastructure
Solution Approach 2:
The system uses a portable hydraulic pumping mechanism integrated into the vehicle-mounted unit to deliver water to misting nozzles. This self-contained hydraulic system eliminates the need for external stationary pumping infrastructure while maintaining adequate water delivery pressure for effective misting
3Temperature
If evaporative cooling is used to cool air, then air temperature is reduced, but the system requires large apparatus mounted to the roof
Solution Approach 1:
The cooling system is segmented into multiple small misting nozzles distributed throughout the vehicle interior rather than using a single large centralized cooling apparatus. Each nozzle independently generates cooling mist, and collectively they provide comprehensive cooling coverage without requiring large roof-mounted equipment
Solution Approach 2:
Instead of cooling the entire vehicle air mass uniformly with a large apparatus, the system applies evaporative cooling locally at multiple points where occupants are present. The misting nozzles are positioned to target specific zones, providing localized cooling where it is most needed and reducing overall system size
4Reliability
If a fan is added to cool persons more effectively in humid environments, then cooling effectiveness in humid conditions is improved, but the system lacks on-board payment system for user control
Solution Approach 1:
The system incorporates an automated payment and control system that allows users to independently activate and control the cooling system. The card reader accepts payment from occupants, and the controller automatically activates the appropriate cooling mode (misting or fan) based on environmental sensors, enabling self-service operation without requiring external operator intervention

Implementation Method 1
a pressurized accumulator to provide a steady mist flow
Implementation Method 2
spraying a fine mist of water into the ambient air in which the mist absorbs the heat and cools the air via evaporative cooling
Implementation Method 3
A fan draws hot air through the pad and blows the resulting cooled air into the vehicle
