Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dish brushes for sweeping machines are cumbersome and costly to maintain due to complex constructions that require complete disassembly for replacing brush elements, leading to inefficient use of materials and increased transportation costs.
Innovation Solution
A demountable dish brush with a central polygonal base plate featuring I-shaped radial profiles and slidable segmental plate elements with trapezium surfaces, secured by a single screw bolt, allowing for easy replacement and reuse of the base plate while minimizing material usage and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dish brush is constructed as a complicated ring element with sliding brush plugs and covered with a circular plate locked with screws, then the brush elements can be mounted, but the replacement process becomes time-consuming and the construction cost increases
Solution Approach 1:
The dish brush is divided into a central base plate and multiple removable segmental plate elements. Each segmental plate element can be independently removed and replaced, allowing quick maintenance without disassembling the entire brush structure. This segmentation enables rapid replacement of worn brush elements while keeping the base plate in use.
Solution Approach 2:
The segmental plate elements with brush plugs are designed as separate, extractable components from the central base plate. This extraction design allows the brush elements to be removed and replaced independently, eliminating the need to disassemble the entire brush structure for maintenance.
2Device complexity
If the brush elements are executed as single plugs with connecting head plates for sliding movement, then the brush can be constructed, but the replacement process requires complete disassembly of the dish brush
Solution Approach 1:
The brush is segmented into a stationary central base plate and movable segmental plate elements. Each segmental element can be independently removed by detaching it from the base plate, allowing easy replacement of brush plugs without affecting other parts of the brush structure.
Solution Approach 2:
The segmental plate elements are designed with dynamic mounting and demounting capabilities, allowing them to be easily attached to and removed from the central base plate. This dynamic design enables quick replacement of worn elements while maintaining a simple overall structure.
3Strength
If the dish brush is made with welded joints for brush plugs, then the structure is strong, but the entire dish brush must be discarded when brush plugs are worn out
Solution Approach 1:
The dish brush is segmented into a durable central base plate and replaceable segmental plate elements with brush plugs. The segmental elements can be removed and replaced independently when worn, while the base plate remains in use. This prevents the need to discard the entire brush structure.
Solution Approach 2:
The segmental plate elements are designed to be discarded when worn out, while the central base plate is recovered and reused. This selective replacement approach minimizes material waste by keeping the main structural component in service indefinitely.
4Ease of operation
If the complete dish brush is transported to the user, then the brush is available for use, but the transport volume and weight are large
Solution Approach 1:
The dish brush system is segmented into a reusable central base plate and replaceable segmental plate elements. Only the segmental elements need to be transported to users, significantly reducing transport weight and volume compared to transporting complete brush assemblies.
Solution Approach 2:
The central base plate is designed as a universal component that can accept different segmental plate elements. This universality allows a single base plate to serve multiple users or applications, reducing the need to transport complete brush assemblies for each user.
5Ease of manufacture
If the heavy steel central base plate is discarded with worn brush plugs, then the brush is replaced, but the costs and transport volume increase
Solution Approach 1:
The dish brush is segmented into a permanent central base plate and replaceable segmental plate elements. This segmentation allows only the small segmental elements to be transported and replaced, rather than the entire heavy base plate, significantly reducing transport volume and costs.
Solution Approach 2:
The segmental plate elements are designed to be discarded when worn, while the central base plate is recovered and reused indefinitely. This approach minimizes the quantity of material that needs to be transported and disposed of.

AI summary
The invention relates to a further developed dish brush (1) for sweeping machines, wherein a central base plate (2) has in top view the form of a polygon with raised contour plates (4). Said raised contour plates (4) are mutually coupled with radially I-shaped radial profiles to take with a sliding movement the demountable segmental plate elements (3). So, a very efficiently constructed and environmentally friendly dish brush for sweeping machines is developed.
