Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing misting systems for outdoor environments lack effective control over the density of the mist produced, which can lead to inefficient evaporative cooling.
Innovation Solution
A portable misting system with a housing containing an air pump, water reservoir, water pump, and air/water nozzle assemblies that allow separate control of air and water flow, enabling adjustable mist density through a mist controller and fan controller, ensuring flexible mounting and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate air and water inputs are provided in the nozzle assembly, then mist density control is improved, but device complexity increases
Solution Approach 1:
The nozzle assembly is segmented into separate air input pathway and water input pathway, allowing independent control of air and water flows. This segmentation enables precise adjustment of mist density by controlling the ratio of air to water without requiring complex external control systems.
Solution Approach 2:
The air pump and water pump are integrated into a single housing unit with coordinated control, merging two separate pumping systems into one compact assembly. This reduces overall system complexity while maintaining the ability to independently control air and water flows for mist density adjustment.
2Adaptability or versatility
If a compact design with flexible mounting is implemented, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The housing is designed with universal mounting features including multiple mounting points and adjustable nozzle orientations, allowing the same compact unit to be installed in various locations and configurations. This universal design provides flexible mounting options without requiring custom manufacturing for each application.
Solution Approach 2:
The nozzle assembly incorporates adjustable components that allow post-installation modification of spray patterns and directions. This dynamic adjustability compensates for variations in manufacturing tolerances and enables precise mist delivery regardless of mounting position or orientation.

AI summary
A portable misting system includes a housing, an air pump carried by the housing to provide a flow of air, a water reservoir carried by the housing to hold a supply of water, and a water pump carried by the water reservoir to provide a flow of water droplets. An air/water nozzle assembly is carried by the housing and includes a nozzle body and a misting nozzle coupled to an output of the nozzle body. The nozzle body has an air input coupled to the air pump to receive the flow of air, and a water input coupled to the water pump to receive the flow of water droplets.
