Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans are bulky and noisy due to their motor design, which occupies space and generates significant noise during operation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a traditional motor is used to rotate the propeller, then the fan can generate wind, but the motor occupies a lot of space and produces considerable noise
Solution Approach 1:
The patent extracts the rotating function from the traditional motor assembly and implements it through a maglev system where electromagnetic fields directly levitate and rotate the propeller blades without a physical motor housing, thereby eliminating the bulky motor structure while maintaining wind generation capability
Solution Approach 2:
The patent replaces the mechanical motor system with a magnetic field-based maglev system, where electromagnetic forces substitute for mechanical rotation, eliminating the need for a traditional motor and reducing both size and noise

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 fan is compact in size and operates quietly by using the maglev assembly to rotate the blades, reducing bulkiness and noise, making it suitable for various applications including cooling electronic devices and propulsion systems.
Implementation Method 1
The maglev assembly is connected to the annular frame. Each of the movable elements is connected to an external end of a corresponding one of the blades and kept floating by the maglev assembly.

AI summary
A fan includes an annular frame, a rail assembly, a driving member and blades. The blades are connected to the driving member. The driving member is electromagnetically movable along the maglev assembly that extends along an edge of the annular frame. The driving member does not contact the annular frame or the maglev assembly so that when the fan is used, the maglev assembly is energized to generate an electromagnetic force between the maglev assembly and the driving member to move the driving member along the edge of the annular frame to drive the blades to rotate. Therefore, the blades can be rotated without having to use any motor behind the annular frame, thereby reducing the volume of the fan.
