Solution Overview
Problem
Existing misting fans are either too simple and require physical actuation or are too complex, large, and tied to an external power supply for continuous use, lacking portability and adjustability in misting rate and wind force.
Innovation Solution
A portable misting fan with an integrated water reservoir, onboard battery power, adjustable wind force, and misting rate, featuring a sonic disk for atomizing water and a mounting system with interchangeable options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If industrial misting fans are used to provide continuous misting effect, then the misting capability is improved, but the device becomes large and requires external power supply
Solution Approach 1:
The patent combines multiple functions into a single portable device: the water reservoir, fan assembly, and power supply are integrated into one unit. The reservoir is positioned within the housing to contain the fan assembly, creating a compact self-contained system that eliminates the need for external water sources and power supplies while maintaining continuous misting capability
Solution Approach 2:
The device is designed to perform multiple functions in one unit: it provides both cooling airflow through the fan assembly and misting through the sonic disk assembly. The mounting system also provides versatility by allowing the device to be mounted in various locations (windows, doors, walls) using different mounting means such as suction cups, magnets, or clamps
2Ease of operation
If simple manual pump systems are used, then the device portability is improved, but the ease of operation deteriorates due to physical actuation requirement
Solution Approach 1:
The patent replaces the manual mechanical pump system with an electronically controlled sonic disk assembly. The sonic disk uses ultrasonic vibrations to atomize water without requiring manual pumping action, and is controlled by an electronic controller that receives power from the onboard power supply, eliminating the need for physical actuation while maintaining portability
Solution Approach 2:
The device is designed to operate autonomously without requiring manual intervention for water pumping. The onboard power supply automatically powers the fan assembly and sonic disk assembly, and the controller manages the operation of these components without user intervention, allowing the device to serve itself and eliminating the need for physical actuation
3Productivity
If fixed position industrial fans are used, then the misting effectiveness is improved, but the adaptability deteriorates
Solution Approach 1:
The patent transforms the device from a fixed position system to a dynamically adaptable system through the mounting system. The mounting arm with pivotable mounting means allows the device to be positioned at various angles and locations, and the multiple mounting options (suction cups, magnets, clamps) enable adaptation to different surfaces and environments while maintaining misting effectiveness
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
Provides a portable, power-independent misting solution with adjustable misting and wind force settings, enhancing user convenience and versatility.
Implementation Method 1
the sonic disk assembly is designed to selectably atomize and disperse water—the water communicated from the internal reservoir—from the sonic disk assembly in one or more of a continuous or intermittent manner
Implementation Method 2
a fan assembly arranged at least partially within said passageway
