Rotary Brush Clamping via Segmented Ring Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior rotary washing brush assemblies face challenges in properly clamping washing brush straps, leading to uneven distribution and long assembly times, and require additional support materials like plastics and aluminum.
Innovation Solution
The rotary washing brush construction features die-cut plate-like brush elements with contoured strips joined to a central band element, clamped by ring elements on the support tube, allowing for adjustable spacing and elimination of additional support materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping systems with rivets and bars are used to clamp straps to the support tube, then the straps can be secured to the support, but the assembly time becomes comparatively long and the strap distribution becomes difficult to control
Solution Approach 1:
The support tube is segmented into multiple identical clamping units, each capable of independently clamping a strap. This modular approach allows for parallel assembly operations and simplifies the replacement of individual clamping units without affecting the entire brush assembly.
Solution Approach 2:
The clamping units are pre-assembled with the straps in a controlled environment, allowing for precise adjustment of clamp position and strap tension before installation. This preliminary configuration ensures optimal strap distribution and eliminates the need for time-consuming on-site adjustments.
2Reliability
If additional support elements made of plastics or aluminium are used to hold washing straps, then the straps can be properly supported, but the device complexity increases and material usage increases
Solution Approach 1:
The support function is merged directly into the rotary brush assembly itself. The support tube serves dual purposes as both the rotational element and the mounting structure for clamping units, eliminating the need for separate support elements made of plastics or aluminium.
Solution Approach 2:
The support tube is designed with universal functionality, serving as both the structural backbone and the mounting platform for clamping units. This multi-functional design reduces the total number of components and simplifies the overall device architecture.
3Reliability
If conventional clamping methods are used, then straps can be secured, but the assembly process becomes time-consuming and difficult to standardize
Solution Approach 1:
The support tube is segmented into multiple identical clamping units, each capable of independently clamping a strap. This modular approach allows for parallel assembly operations and simplifies the replacement of individual clamping units without affecting the entire brush assembly.
Solution Approach 2:
The clamping mechanism uses adjustable parameters such as clamp position and compression force to optimize strap securing. These parameters can be standardized during manufacturing and easily adjusted during maintenance, improving both assembly ease and clamping reliability.

Function Achieved in This Case
This design achieves optimal strap distribution, quick and easy assembly, reliable clamping, and reduced material usage, resulting in a cost-effective and eco-friendly washing brush assembly with improved durability and reduced spare part shipment volume.
Implementation Method 1
A pair of ring elements, threaded on the support tube, on both sides of the brush element, clamp said central band element so as to space the contoured strips from the support tube and cause opposite strips to be moved to one another by pairs, with a substantially 90° arrangement with respect to the support tube axis.
