Vacuum Cleaner Rotating Brush Coupler to Prevent Debris Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face issues with debris such as hairs and dust being trapped at the end of the rotating brush or concentrated in a particular region, leading to difficulty in rotation and inefficient cleaning, especially on smooth floors.
Innovation Solution
A vacuum cleaner design featuring a coupler that aligns the rotation axes of first and second rotating brushes, with bristles having symmetrical textures inclined opposite to the rotation direction, and a dust guide system to prevent debris accumulation and facilitate efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the strap portion and antistatic portion extend in the spiral direction of the nozzle body, then the rotary cleaning unit can effectively clean the floor surface, but debris such as hairs and dust is trapped at an end of the rotary cleaning unit
Solution Approach 1:
The patent applies asymmetry by configuring the strap portion and antistatic portion to extend in the longitudinal direction rather than spiral direction, creating an asymmetric debris flow path that prevents accumulation at the end of the rotary cleaning unit. The textured surface is also configured with asymmetric orientation to guide debris toward the inlet.
2Object-generated harmful factors
If the strap portion and antistatic portion extend in the longitudinal direction of the nozzle body, then debris accumulation at the end is reduced, but debris such as hairs and dust is concentrated in a particular region of the rotary cleaning unit
Solution Approach 1:
The patent applies local quality by configuring the textured surface with specific orientation and properties in different regions. The strap portion and antistatic portion have different textures oriented to guide debris flow, creating localized debris pathways that distribute debris evenly toward the inlet rather than concentrating it in one region.
3Object-generated harmful factors
If multiple fiber layers with different textures are attached to the outer surface of the body, then debris distribution is improved, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the functions of multiple fiber layers with different textures into a single integrated rotary cleaning unit design. The strap portion and antistatic portion are configured as unified components with different textures, eliminating the need for separate attachment of multiple layers while achieving the same debris distribution effect.
4Speed
If the rotary cleaning unit rotates at high speed, then fine dust can be lifted and removed efficiently, but debris accumulates at the end causing difficulty in rotation
Solution Approach 1:
The patent applies preliminary action by configuring the textured surface and debris flow paths to guide debris toward the inlet before it can accumulate at the end of the rotary cleaning unit. This preventive configuration ensures that even at high rotation speeds, debris is continuously directed away from the end region, maintaining smooth rotation.
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
Prevents debris from being trapped at the end of the rotating brush or concentrated in a particular region, ensuring smooth operation and effective cleaning by guiding debris towards the inlet for easy removal.
Implementation Method 1
The plurality of bristles is repeatedly folded and unfolded while periodically coming into contact with the floor during the process of rotating the rotary cleaning unit
Implementation Method 2
Debris such as hairs and dust may be easily attached between the bristles of the rotary cleaning unit
Implementation Method 3
A vacuum cleaner capable of clearly cleaning a smooth floor by removing dust with a rotating brush
