Multifunctional Handheld Fan With Integrated Lighting And Flashlight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld fans have a single blowing function, which limits user experience and applicability, especially in nighttime use.
Innovation Solution
A multifunctional handheld fan is designed with a fan component, a lighting component, and a flashlight component, integrated into a single device. The fan component includes a tuyere, fan motor, and fan impeller, while the lighting component features an LED light and a focusing barrel set for adjustable focal length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handheld fans only have a blowing function, then the device structure is simple, but the applicability and user experience are limited
Solution Approach 1:
The handheld fan integrates multiple functions including blowing (fan motor), lighting (LED light), and flashlight (flashlight component with telescopic pipe) into a single device. The fan main housing contains the fan motor and impeller for air circulation, while the handle housing contains the battery and flashlight component. This multi-functional design resolves the contradiction by providing versatility without excessive complexity through integrated architecture.
Solution Approach 2:
The patent combines previously separate devices (handheld fan, LED light, flashlight) into one integrated unit. The fan main housing and handle housing are connected through a connecting housing, with shared power supply from the battery. This merging approach achieves versatility while maintaining reasonable structural complexity through unified design.
2Adaptability or versatility
If multiple components are integrated into the handheld fan, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The handheld fan is divided into distinct functional modules: fan main housing (containing fan motor and impeller), connecting housing (for electrical connections), and handle housing (containing battery and flashlight component). Each module is independently designed and assembled, which manages structural complexity while achieving enhanced functionality through modular integration.
Solution Approach 2:
The flashlight component is nested within the handle housing, with the telescopic pipe extending from the handle housing. The LED light is integrated into the fan main housing structure. This nesting arrangement reduces overall device complexity by embedding components within existing structural elements rather than adding separate external attachments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
