Luminous Fan Light Guide Ring Bypasses Opaque Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous fans with opaque fasteners on their frames block light sources, preventing a complete ring-shaped illumination effect.
Innovation Solution
A luminous fan design featuring a light guide member with an outer ring and inner rings that surround the fan frame, allowing light sources to be placed between them, ensuring the ring-shaped illumination is not obstructed by the mounting parts, thus creating a complete annulus of light and an annular halo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opaque fasteners are used to assemble the fan frame, then the structural strength and assembly reliability are improved, but the light transmission is blocked, preventing complete ring-shaped illumination
Solution Approach 1:
The patent introduces a light guide member as an intermediary component between the light source and the fan frame. This light guide member transmits light from the light source located on the fan frame to the outer perimeter, bypassing the opaque fasteners. The light guide member acts as a mediator that allows light to pass through the assembly without being blocked by the fasteners, thus achieving complete ring-shaped illumination while maintaining the structural integrity provided by the opaque fasteners.
Solution Approach 2:
The patent replaces the direct mechanical light transmission path with an optical path through the light guide member. Instead of relying on light to pass through the opaque fasteners (mechanical structure), the light guide member creates a separate optical pathway that guides light from the source around the fan frame perimeter, substituting the mechanical limitation with an optical solution.
2Device complexity
If light sources are mounted directly on the fan frame toward the propeller, then the illumination structure is simplified, but the fasteners block the light and create incomplete ring-shaped illumination
Solution Approach 1:
The light guide member serves as an intermediary that extends the illumination path from the light source on the fan frame to the outer perimeter. This intermediary component allows the light to travel around the fan frame without being blocked by the fasteners, achieving complete ring-shaped illumination while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent introduces a radial dimension to the light transmission path by using the light guide member that extends from the fan frame outward to the perimeter. This dimensional extension allows light to bypass the fasteners located on the fan frame, creating a complete circular illumination pattern in the radial direction.
