Solution Overview

Problem

Current fan assemblies prioritize heat-dissipation performance but fail to provide significant visual effects while maintaining effective airflow.

Innovation Solution

A fan assembly design incorporating a light-emitting unit between the base and the fan, a lighting effect component with an inclined inner surface for reflection, and a low-height structure to minimize airflow disruption, along with optional features like an arc reflector and light-collecting components for enhanced visual effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a lighting effect component is added to provide visual effects, then the visual appeal is improved, but the airflow and heat-dissipation performance deteriorate

Engineering Contradiction:
Improvevisual effectVSAvoidheat-dissipation performance
Core Design Contradiction:
Illumination intensityVSProductivity

Solution Approach 1:

The lighting effect component is designed with a low height dimension that is less than the distance between the blade top surface and the base, placing it in a lower spatial dimension that does not obstruct the primary airflow path. This dimensional arrangement allows the lighting component to provide visual effects without significantly interfering with the fan's heat-dissipation function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If the lighting effect component is made taller to enhance visual effects, then the visual appeal is improved, but the airflow obstruction increases

Engineering Contradiction:
Improvevisual effectVSAvoidairflow disruption
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The height parameter of the lighting effect component is specifically controlled to be less than the distance between the blade top surface and the base. This parameter change ensures that the lighting component remains below the blade clearance, minimizing its impact on airflow while still providing adequate visual effects.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If the light-emitting unit is placed closer to the blades to enhance lighting effects, then the visual effect is improved, but the risk of light obstruction and airflow interference increases

Engineering Contradiction:
Improvelighting effectVSAvoidlight obstruction risk
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting effect component acts as an intermediary element between the light-emitting unit and the external environment. It reflects light from the light-emitting unit (which is positioned safely between the base and the central part) toward the front side, providing enhanced visual effects without requiring the light source to be positioned in obstructive locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

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 both improved heat-dissipation performance and visually appealing effects without compromising airflow, allowing users to see reflected light from the front side while maintaining efficient cooling.

Implementation Method 1

The light emitted by the light-emitting unit is adapted for emitting to the inclined inner surface and being reflected towards a direction away from the base

AI summary

A fan assembly including a base, a fan, a light-emitting unit, and a lighting effect component is provided. The fan is rotatably disposed above the base, and includes a central part and multiple blades extending outwards from the central part, and each of the blades has a top surface away from the base. The light-emitting unit is disposed on the base and located between the base and the central part of the fan. The lighting effect component is disposed on the base and surrounds the light-emitting unit. A projection of the lighting effect component projected onto the base is greater than a projection of the fan projected onto the base. A height of the lighting effect component protruding from the base is less than a distance between the top surface of one of the blades and the base. The lighting effect component includes an inclined inner surface.
