Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting fan devices require multiple parts and LED light sources for illumination, making maintenance, repair, and parts replacement inconvenient and inefficient.
Innovation Solution
A light emitting fan device design featuring a main fan frame, fan assembly, first and second light guide rings, light emitting assembly, and securing fan frame ring, with anti-vibration mounts to secure the light guide rings and assembly, allowing for illumination of multiple surfaces with minimal parts and facilitating maintenance by limiting vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple LED light sources and parts are added to achieve illumination in different directions, then illumination coverage is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
Multiple LED light sources are integrated into a single light emitting assembly that illuminates multiple surfaces (front, rear, left, right, and top surfaces) through strategic positioning and optical design, reducing the total number of separate parts while maintaining comprehensive illumination coverage
Solution Approach 2:
The light emitting assembly serves multiple functions by providing illumination to at least five different surfaces of the fan device simultaneously, making a single component perform what previously required multiple separate light sources and parts
2Illumination intensity
If multiple parts and LED light sources are assembled to the fan, then illumination capability is improved, but ease of repair and maintenance deteriorate
Solution Approach 1:
The lighting system is segmented into a modular light emitting assembly that can be independently removed and replaced. The anti-vibration mounts enable this assembly to be easily detached from the fan frame without affecting other components, significantly improving maintenance convenience
Solution Approach 2:
The light emitting assembly is extracted as a separate, independently replaceable module from the fan structure. The anti-vibration mounts facilitate easy removal and installation, allowing the lighting component to be taken out for maintenance without disassembling the entire fan
3Stability of the object's composition
If anti-vibration mounts are added to secure light guide rings, then stability is improved, but device complexity increases
Solution Approach 1:
The anti-vibration mounts are integrated into the existing fan frame structure and work automatically to limit vertical movement of the light guide rings. The mounts utilize the vibration and movement characteristics of the rotating fan to self-adjust and secure the light guide rings, providing stability without requiring additional complex active control mechanisms
