Modular Washing Brush Assembly for Replaceable Fringed Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanized washing brushes for vehicles and aircrafts face challenges such as complex and time-consuming assembly of flexible elements, high storage and transport costs, inability to easily replace worn or damaged bristles, and homogeneous cleaning action that cannot intensify in specific areas.
Innovation Solution
A brush device with flexible support and fringed bands that can be quickly and safely fixed using a fixing mechanism with elongated body and protruding arms, allowing for single-layer or multi-layer bands to be easily added or replaced, assembled with minimal tools, and providing an elastic cleaning action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixation methods are used for fringed bands, then the bands are securely fixed to the support, but the assembly process becomes very complex and time-consuming requiring skilled workers
Solution Approach 1:
The brush device is divided into modular components: a support means with seats, band means with holes, and fixing means with arms. Each component can be independently manufactured and assembled, simplifying the overall assembly process while maintaining secure fixation through the interlocking mechanism of arms engaging holes in both the support and bands.
Solution Approach 2:
The fixing means acts as an intermediary element between the support means and the band means. The elongated body with protruding arms provides a simple connection mechanism that bridges the support and bands, enabling secure fixation without complex assembly procedures or skilled labor.
2Productivity
If brushes are assembled with fringed bands fixed during production, then the brushes are ready for use, but storage and transport costs increase due to bulky pre-assembled brushes
Solution Approach 1:
The brush device is segmented into separable components (support means, band means, fixing means) that can be stored and transported independently in a compact manner. Assembly occurs either during production or at the installation site, reducing storage and transport requirements compared to pre-assembled bulky brushes.
Solution Approach 2:
The support means is pre-configured with seats and the fixing means with protruding arms during manufacturing, but the band means is attached later. This preliminary preparation of components allows for simplified storage and transport while enabling quick assembly when needed, balancing readiness with reduced bulk.
3Stability of the object's composition
If traditional fixed brushes are used, then the structure is stable, but the user cannot easily replace worn or damaged bands
Solution Approach 1:
The fixing means provides a dynamic connection that allows bands to be easily removed and replaced by the user without requiring disassembly of the entire brush structure. The protruding arms can be disengaged from the holes in the bands and support means, enabling maintenance and replacement while maintaining structural stability during normal operation.
Solution Approach 2:
The separable design with modular components (support means, band means, fixing means) enables easy replacement of worn bands. Users can remove damaged bands and install new ones by simply repositioning the fixing means, maintaining structural integrity during use while facilitating simple repairs.
4Device complexity
If homogeneous brushes are used, then the design is simple, but the cleaning action cannot be intensified in specific areas
Solution Approach 1:
Different band means can be selected and installed in specific seats on the support means to provide localized cleaning intensity. The support means with multiple seats allows configuration of bands with different properties (length, material, fringe density) in specific areas, enabling intensified cleaning where needed while maintaining overall design simplicity.

AI summary
A brush device for mechanic washing comprises a flexible support means (3) that can be fixed to a respective roller to coat the cylindrical surface of said roller. The device (1) further comprises a plurality of first band means (4) each provided with fringes and it (1) comprises a plurality of fixing means (6) each assigned to fix at least one of the first band means (4) to the support means (3). Each of said fixing means (6) is provided with an elongated body means (7) having at least a protruding arm means (8). In the assembled condition of the device (1), the body means (7) of a fixing means (6) is assigned to match with the transversal median portion (5) of a corresponding first band means (4) and each arm means (8) of said body means (7) is assigned to engage a respective first pass through hole (10) made through said transversal median portion (5) of said first band means (4) and to engage a respective second pass through hole (11) made through the support means (3). In said assembled condition, each arm means (8) of each fixing means (6) is locked to the support means (3). The flexible support means (3) is provided with a plurality of housings (15) each having a perimeter wall (16) protruding perpendicularly to the support means (3) and assigned to accommodate the transversal median portion (5) of at least a first band means (4) and to accommodate a corresponding body means (7). Each housing (15) is also equipped with of a second hole (11) for each arm means (8) of the body means (7). The side of the body means (7) opposed to the arm means (8) has a set of concavity (18) assigned to removably house respective teeth of a thrust means for pushing the arm means (8) into the holes first (10) and second (11) and for translating the body means (7) and the transversal median portion (5) of the first band means (4) toward and against the bottom of the housing means (15) as long as the fixing of the arm means (8) to the support means (3) is carried out.
