Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner brush heads with cylindrical bristles suffer from high tangling issues with hair, poor cleaning effectiveness for firmly adhered garbage, limited cleaning area, and inadequate dust collection due to poor linkage between bristles and dust collection ports, leading to user fatigue and inefficient cleaning.
Innovation Solution
A vacuum cleaner brush head design featuring reciprocally moving front and rear wiping plates with a dust passing hole and cleaning cloth, integrated with a water spraying system, which enhances cleaning area, force, and dust collection efficiency by directional dust pushing and separation of water and dust collection functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cylindrical bristles are used in the brush head, then the brush head can rotate to clean the floor, but the bristles are prone to tangling with hair and have limited cleaning area
Solution Approach 1:
The patent divides the single rotating cylindrical brush into multiple independent wiping plates (front wiping plate, rear wiping plate, left wiping plate, right wiping plate) that move reciprocally. Each wiping plate has its own cleaning cloth and dust passing hole, segmenting the cleaning function to eliminate hair entanglement while expanding the overall cleaning area through coordinated movement of multiple plates.
Solution Approach 2:
The patent transitions from a static rotating cylindrical brush to dynamic reciprocating wiping plates. The wiping plates move back and forth in opposite directions under the control of a crankshaft mechanism, creating dynamic cleaning action that prevents hair entanglement while maintaining continuous contact with the floor surface.
2Reliability
If the user presses the vacuum cleaner brush head hard towards the floor to improve cleaning effect, then firmly adhered garbage can be removed, but the user experiences physical burden
Solution Approach 1:
The patent employs reciprocating motion of the wiping plates at controlled speeds (front plate 5-15rpm, rear plate 10-20rpm) to generate dynamic cleaning force. This mechanical oscillation enhances the cleaning effect on firmly adhered garbage without requiring the user to apply excessive downward pressure, reducing physical burden while maintaining cleaning effectiveness.
Solution Approach 2:
The water spraying assembly sprays water onto the floor before the wiping plates arrive at that location. This preliminary wetting softens firmly adhered garbage and dust, making them easier to remove during the wiping action, thereby reducing the force needed by the user while improving cleaning effectiveness.
3Reliability
If water spraying devices are provided in the brush head to improve cleaning effect, then cleaning area is enhanced, but water wets the garbage making it stuck to the floor and moisture enters the dust collection system
Solution Approach 1:
The patent separates the water spraying function from the dust collection function by positioning the water spraying port between the front and rear wiping plates, away from the dust collection port. The dust collection port is located at the front bottom of the brush head body, while water is sprayed at a different location, preventing water from directly entering the dust collection system while still enabling effective wet cleaning.
Solution Approach 2:
The water spraying assembly performs preliminary wetting of the floor and garbage before the wiping plates pass over. This advance spraying softens adhered debris and dust, making them easier to remove during the wiping action, thereby improving cleaning effectiveness without causing water to pool near the dust collection port.
4Productivity
If cylindrical bristles are used to scrape dust into the dust collection port, then dust can be removed, but the linkage action between bristles and dust collection port is poor resulting in much room for improvement in dust collection effect
Solution Approach 1:
The patent divides the dust collection function across multiple wiping plates, each with its own dust passing hole positioned to align with the dust collection port during reciprocating motion. This segmentation ensures that dust collected by each plate is efficiently channeled into the dust collection port, improving the linkage between cleaning action and dust collection compared to a single cylindrical brush.
Solution Approach 2:
The reciprocating motion of the wiping plates creates dynamic alignment between the dust passing holes and the dust collection port. As the plates move back and forth, the dust passing holes continuously present collected dust to the dust collection port, enhancing the linkage effect and dust collection efficiency compared to static cylindrical bristles.
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
Significantly improves cleaning area and effectiveness by overcoming hair entanglement and firmly adhered debris issues, ensuring efficient dust collection and reducing user effort through enhanced friction and directional dust collection, while preventing motor damage from water ingress.
Implementation Method 1
Vacuum cleaner is a cleaning device that uses negative pressure to generate suction to remove dirt
Implementation Method 2
a water spraying assembly, wherein a water spraying port of the water spraying assembly is provided on the bottom of the brush head body
Implementation Method 3
cleaning cloth is provided on the front wiping plate and the rear wiping plate, respectively
Implementation Method 4
the acting force is small, thus it can clean floating dust only but is difficult to clean the garbage firmly adhered to the floor
