Retractable Fan Lamp Layout With Integrated Driver Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan lamps occupy a large space due to their bulky design, making transportation inconvenient.
Innovation Solution
The fan lamp integrates the driving motor of the blade assembly and the light source assembly with a single driver, reducing the number of components and parts, which includes a ceiling assembly, a hanger rod, and a ceiling fan assembly, which reduces the overall size and enhances the compactness and ease of transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fan lamp uses separate drivers for the blade assembly and light source assembly, then the control functionality is independent and reliable, but the number of components increases and the overall size becomes large
Solution Approach 1:
The patent combines the control functions of the blade assembly and light source assembly into a single integrated driver unit. This driver includes a control module that can independently control both the motor driver (for blade rotation) and the light source driver (for LED lighting), thereby reducing the total number of components while maintaining independent control functionality through software/module architecture.
2Volume of moving object
If the fan lamp adopts a traditional separate design for fan and lighting components, then each component can be optimized independently, but the overall size occupied is large and transportation is inconvenient
Solution Approach 1:
The patent implements a nested structure where the light source assembly is positioned within the space occupied by the blade assembly's mounting structure. The lighting components are integrated into the hollow interior space of the fan housing, allowing both systems to occupy overlapping spatial volumes and thereby reducing the overall external dimensions of the fan lamp.
3Manufacturing precision
If the fan lamp uses multiple separate drivers for different assemblies, then the control precision for each assembly is high, but the device complexity and space requirement increase
Solution Approach 1:
The integrated driver is designed as a universal control unit that can perform multiple functions: it includes a motor driver for controlling blade rotation speed and direction, a light source driver for controlling LED brightness and timing, and a control module that coordinates both functions. This multi-functional design maintains high control precision for each assembly while simplifying the overall driver configuration into a single integrated unit.
