Wearable Misting Nozzle Control for Personal Cooling Vests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling and misting systems fail to provide effective, easy-to-use, and controllable personal cooling and misting solutions integrated within articles of clothing, particularly for individuals exposed to extreme heat and high activity levels, such as workers in safety operations.
Innovation Solution
A self-contained cooling and misting system is integrated into an article of clothing, such as a safety vest, featuring a water reservoir, electrically operated pump, and spray nozzle, with a programmable controller for controlling pump functions and misting patterns, and includes biometric and environmental sensors for adaptive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling and misting system is integrated into an article of clothing, then personal cooling effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cooling components (water reservoir, pump, tubing, misting nozzle) into a single integrated clothing system, merging functions that would traditionally be separate devices into one unified wearable unit
Solution Approach 2:
The clothing article serves multiple functions: it provides the structural framework for the system, contains the water reservoir, houses the pump mechanism, and delivers the mist through integrated nozzles, making the garment itself a multi-functional cooling device
2Ease of operation
If a programmable controller with sensors is added to enable adaptive operation, then cooling effectiveness and user comfort are improved, but device complexity and power consumption increase
Solution Approach 1:
The system incorporates biometric sensors that detect user physiological data (such as skin temperature or heart rate) and environmental sensors that monitor ambient conditions, feeding this information to the programmable controller which automatically adjusts pump operation and misting intensity accordingly
Solution Approach 2:
The system performs self-adjustment based on sensor input, with the programmable controller automatically modifying cooling parameters without user intervention, allowing the system to serve itself by adapting to changing conditions in real-time
3Ease of operation
If the water reservoir is made removable for ease of refilling, then ease of operation is improved, but reliability of fluid connection may worsen
Solution Approach 1:
The water reservoir is designed as a separate, removable component that can be detached from the main clothing body for independent refilling, allowing users to service the water supply without removing or altering the entire garment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively provides controlled misting to cool the wearer without drenching them, ensuring hydration and comfort in extreme conditions, with programmable and adaptive features for various environmental scenarios.
Implementation Method 1
a spray nozzle with a misting head that projects a cooling water spray mist in front of a wearer's face so that the wearer walks into the cooling mist to be refreshed
Data Source
AI summary
An improved personal cooling misting system having a dual rotating articulating nozzle with an integrally formed purge valve. The improved personal cooling misting system provides for a wearable fluid reservoir to contain a volume of misting fluid, and an electrically operated pump proximate to the reservoir to pump the misting fluid from the reservoir to a misting head. The misting head facilitates atomizing the misting fluid. The improved system further provides for feed tubing to direct the misting fluid from the reservoir to the pump, and distributive tubing to direct the misting fluid from the pump to the misting head. The improved system also includes a pump control to control at least one of a pressure and a flow rate of the misting fluid.
