Cleaner Agitator Brush Assembly for Easier Spiral Brush Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners face manufacturing difficulties due to the complex process of attaching brushes to the agitator body, which is typically done through injection molding and requires precise hole formation for spiral brush arrangement.
Innovation Solution
The agitator design includes a frame with installation spaces and side caps that support a brush assembly, allowing for easier assembly and attachment of brushes, with the brush assembly inserted through openings and side caps fixed to the frame, facilitating rotational mounting and improved manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the body is manufactured through injection molding and brushes are fixed to holes in the body, then the agitator can be produced with a fixed structure, but the manufacturing process becomes complex and difficult
Solution Approach 1:
The agitator is divided into separate components: a body, a brush assembly, and side caps. The brush assembly is a separate unit that can be manufactured independently and then assembled to the body, eliminating the need for complex injection molding with integrated brush holes. This segmentation simplifies manufacturing while maintaining structural integrity through the side caps that secure the assembly.
2Reliability
If the brushes are fixed onto the outer surface of the body through injection molding, then the brushes are securely attached, but the assembly process becomes time-consuming and reduces productivity
Solution Approach 1:
The brush assembly is pre-assembled as a complete unit before being attached to the body. The brushes are already positioned and secured within the brush assembly structure, allowing for quick installation onto the agitator body. This preliminary preparation of the brush assembly significantly reduces assembly time and increases manufacturing productivity while ensuring proper brush positioning.
3Ease of operation
If the brushes are arranged in holes formed in the outer surface of the body in a spiral, then the brushes can effectively contact the cleaning target, but the manufacturing precision requirements increase
Solution Approach 1:
The spiral brush arrangement is achieved in the separate brush assembly rather than through complex holes in the body. The brush assembly structure itself provides the spiral configuration, eliminating the need for high-precision hole formation in the body. This approach maintains cleaning effectiveness while reducing manufacturing precision requirements for the body component.

AI summary
There is provided a cleaner including an agitator, and a mounting portion on which the agitator is rotatably mounted. The agitator includes a brush assembly having brushes, a frame that includes a first opening into which the brush assembly is inserted, an installation space for receiving therein the brush assembly, and a second opening through which the brushes protrude, and first and second side caps that are connected to the frame and support the brush assembly.
