Detachable Tower Fan Module for Safe Cleaning and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical tower fans are difficult to clean due to the accumulation of dust and dirt on blower fan blades, and the internal electrical components are at risk of exposure to cleaning fluids, while the wiring layout complicates assembly and disassembly.
Innovation Solution
A modular design with a detachable fan module and drive module, allowing easy separation for cleaning without tools, where the fan module includes a blower fan and the drive module houses electrical components, and a wireless control interface eliminates the need for internal wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is made sealed to protect electrical components, then reliability is improved, but ease of cleaning deteriorates
Solution Approach 1:
The tower fan is divided into separate modules: a fan module containing the blower fan and a drive module containing electrical components. This segmentation allows the fan module to be detached for cleaning while the drive module remains sealed and protected, resolving the contradiction between accessibility for cleaning and protection of electrical components.
2Ease of operation
If the fan module is made detachable for cleaning, then ease of cleaning is improved, but device complexity increases
Solution Approach 1:
The tower fan is divided into separate modules: a fan module containing the blower fan and a drive module containing electrical components. This segmentation allows the fan module to be detached for cleaning while the drive module remains sealed and protected, resolving the contradiction between accessibility for cleaning and protection of electrical components.
3Reliability
If control wirings are run within the housing, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The control wirings are extracted from the housing and relocated to the drive module, which contains the electrical components. This eliminates the need to run wirings through the housing, simplifying assembly while maintaining protection of the electrical components and wirings within the sealed drive module.
