Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling fan blade cleaning tools are inefficient in effectively cleaning individual blades, lacking a mechanism to ensure thorough dust removal and secure blade alignment during the cleaning process.
Innovation Solution
A ceiling fan blade cleaning vacuum attachment featuring a housing with an upper and lower brush, driven by a pneumatic brush motor, which uses suction from a vacuum cleaner to rotate the brushes and secure the blade with a hanging latch dog, ensuring thorough cleaning and prevention of blade ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning methods are used for ceiling fan blades, then the device complexity is low, but the cleaning effectiveness and dust removal capability are insufficient
Solution Approach 1:
The patent combines multiple cleaning components (upper brush, lower brush, vacuum attachment) into a single integrated device that securely holds the fan blade and simultaneously cleans both surfaces, improving cleaning effectiveness while maintaining reasonable device complexity
Solution Approach 2:
The cleaning device is designed to perform multiple functions: securing the blade with latch dogs, cleaning both upper and lower surfaces with rotating brushes, and removing dust through vacuum suction, making it a versatile multi-functional tool
2Manufacturing precision
If a secure blade alignment mechanism is implemented, then the cleaning thoroughness improves, but the device complexity increases
Solution Approach 1:
The blade securing mechanism is divided into separate latch dogs (upper and lower) that independently engage with the blade, allowing precise alignment and secure positioning without requiring a complex monolithic structure
Solution Approach 2:
The latch dogs act as intermediary elements between the housing and the blade, providing secure alignment and positioning while allowing for easy insertion and removal of the blade for cleaning
3Reliability
If brushes are driven by vacuum suction, then the cleaning effectiveness increases, but the energy efficiency decreases
Solution Approach 1:
The brush driving mechanism is self-powered by the vacuum suction itself, which automatically rotates the brushes without requiring separate motors or power sources, maintaining cleaning effectiveness while avoiding additional energy consumption
Solution Approach 2:
The patent uses pneumatic power from the vacuum suction to drive the brush rotation, leveraging the existing air flow to perform mechanical work and eliminate the need for separate electrical motors
4Area of stationary object
If both upper and lower brushes are provided, then the cleaning coverage improves, but the device complexity increases
Solution Approach 1:
The upper and lower brushes are positioned asymmetrically to target different surfaces of the blade, with the upper brush cleaning the top surface and the lower brush cleaning the bottom surface, maximizing cleaning coverage with minimal components
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 solution enables thorough cleaning of ceiling fan blades by rotating brushes driven by vacuum suction, ensuring both surfaces are cleaned and preventing blade ejection during the process, thus improving cleaning efficiency and safety.
Implementation Method 1
Suction generated by the vacuum cleaner may draw air through the blade slot and through the neck of the housing
Implementation Method 2
The air may turn a turbine rotor of the pneumatic brush motor, which may drive the upper brush and the lower brush to sweep the individual blade
