Partially Luminous Fan Blade Structure to Reduce Dazzling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminous fans suffer from excessive luminous effects that cause dazzling, leading to a poor user experience due to uncontrolled light transmission across the entire surface.
Innovation Solution
A partially luminous fan blade design incorporating a light guide bracket and annular sleeve with a light-shielding skirt, which restricts light leakage and creates a partial luminous effect by guiding light through the bracket while blocking it in the sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the entire fan surface is made luminous, then the luminous effect is enhanced, but the user experience deteriorates due to dazzling
Solution Approach 1:
The patent applies local quality by making only specific portions of the fan luminous rather than the entire surface. The light guide bracket and annular sleeve are selectively positioned to create localized luminous regions, allowing certain areas to emit light while other areas remain dark, thus avoiding the dazzling effect of complete surface illumination.
Solution Approach 2:
The fan structure is segmented into luminous and non-luminous portions. The light guide bracket and annular sleeve are separate components that can be independently positioned and configured, allowing the luminous effect to be divided into discrete segments rather than a continuous uniform illumination across the entire fan surface.
2Illumination intensity
If light transmission is not restricted, then the luminous effect is stronger, but the control over light distribution is lost
Solution Approach 1:
The annular sleeve acts as an intermediary component between the light source and the external environment. It mediates light distribution by selectively blocking light in certain directions while allowing it to pass through other paths, thus providing control over light distribution without completely restricting the luminous effect.
Solution Approach 2:
The patent extracts and isolates the light control function into a separate annular sleeve component. This sleeve can be independently designed and positioned to control light distribution, separating the light transmission function from the structural components and allowing independent optimization of light control.
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
The design achieves a soft, partial luminous effect by limiting light leakage, reducing dazzling and enhancing visual perception with a clearer, controlled illumination.
Implementation Method 1
the light guide bracket produces a luminous effect by guiding light
Implementation Method 2
the annular sleeve blocks light leakage, thereby making the fan blade produce a partial luminous effect

AI summary
A partially luminous fan blade and fan containing same. The fan blade includes a light guide bracket, an annular sleeve, and a plurality of blades. The light guide bracket is formed with a shaft connection portion. The annular sleeve is integrated with the blades. The annular sleeve and the light guide bracket together form a hub portion of the fan blade. The annular sleeve is connected to the light guide bracket. The annular sleeve is provided with a light-shielding skirt. A bottom edge of the light-shielding skirt is lower than that of the light guide bracket.
