Cleaning Brush With Recessed Groove for Rod-Profile Stains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning brushes are inefficient and laborious for removing stubborn dirt from rod-shaped profiles due to limited contact area with the scraper, requiring repetitive motion.
Innovation Solution
A cleaning brush design featuring a brush holder with a grip end, cleaning end, and a cleaning assembly that includes a mounting seat, bristles, and a scraper with a recessed profile cleaning groove, enhancing contact area and cleaning efficiency by embedding the rod-shaped profile in the groove during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional scraper is used to clean a rod-shaped profile, then the cleaning process can be performed, but the contact area between the scraper and the profile is limited, requiring repetitive motions that reduce cleaning efficiency
Solution Approach 1:
The scraper transitions from a flat two-dimensional surface to a three-dimensional profile cleaning groove with circular arc cross-section. This dimensional change allows the groove to envelop the rod-shaped profile, dramatically increasing the contact area from a line contact to a surface contact, thereby enabling most stains to be removed in a single motion
Solution Approach 2:
The scraper's contact surface geometry is changed from flat to a circular arc-shaped groove. This parameter change in the scraper's cross-sectional shape allows it to conform to the rod-shaped profile, maximizing contact area and eliminating the need for repetitive cleaning motions
2Adaptability or versatility
If a fixed cleaning assembly is used, then the structure is simple, but it cannot accommodate rod-shaped profiles of various diameters, reducing adaptability
Solution Approach 1:
The cleaning assembly is designed with detachable connections between the mounting seat and the brush holder, and between the bristles and the mounting seat. This dynamic configuration allows the cleaning assembly to be disassembled and reassembled, enabling adaptation to different rod diameters by adjusting the mounting position or replacing components
Solution Approach 2:
The cleaning assembly is divided into separable components: the mounting seat, the bristles, and the scraper. This segmentation allows each component to be independently designed and adjusted, providing flexibility to accommodate various rod-shaped profile dimensions while maintaining overall structural simplicity
