Cleaning Machine Brush Design with Reversible Shaft for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines require distinct brushes for different functions, leading to increased manufacturing costs and complexity.
Innovation Solution
A cleaning machine design that uses a single brush with interchangeable ends, allowing the same brush to function as both a front and rear brush by reversing its orientation and attaching it to different shaped members, thereby reducing the need for separate brushes and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate brushes are used for first brush and second brush, then each brush can be optimized for its specific function, but manufacturing cost increases and part complexity increases
Solution Approach 1:
The brush shaft is designed with two different connecting portions at its two ends, allowing a single brush to be universally attached to both the first brush attaching member and the second brush attaching member. This multi-functionality enables one brush to replace what would traditionally require two separate brushes, reducing manufacturing cost while maintaining functional optimization through proper orientation
Solution Approach 2:
The brush shaft is segmented into two distinct ends, each with a different connecting portion shape. This segmentation allows the single brush to interface with different attaching members by reversing its orientation, effectively creating two functional configurations from one physical component
2Reliability
If separate brushes are used for first brush and second brush, then each brush can be optimized for its specific function, but device complexity increases
Solution Approach 1:
The brush shaft serves multiple functions by incorporating two different connecting portions, allowing it to be attached to either the first or second brush attaching member. This reduces the overall number of brush components needed in the device, simplifying the brush system while maintaining functional optimization
Solution Approach 2:
The functionality of two separate brushes is merged into a single brush component. By combining the features of both brushes into one unit with reversible orientation, the device complexity is reduced while maintaining the optimized cleaning functions of both positions
3Ease of manufacture
If a single brush with interchangeable ends is used, then manufacturing cost is reduced and design is simplified, but the brush must be detachably attached to different shaped members
Solution Approach 1:
The brush shaft incorporates two different connecting portions that enable dynamic reconfiguration. By reversing the orientation of the single brush, it can be attached to different brush attaching members, providing operational flexibility without requiring multiple permanent brush installations

AI summary
A cleaning machine may include: a first brush including a first brush shaft and a first brush body held by the first brush shaft; a second brush including a second brush shaft and a second brush body held on the second brush shaft; a first brush attaching member having a first shape, wherein one end of the first brush shaft is detachably attached to the first brush attaching member; and a second brush attaching member having a second shape, wherein one end of the second brush shaft is detachably attached to the second brush attaching member. The one end of the first brush shaft may have a first corresponding shape that corresponds to the first shape. The one end of the second brush shaft may have a second corresponding shape that corresponds to the second shape. Other end of the first brush shaft may have the second corresponding shape.
