Semi-Circular Coupling for Rotary Brush Bristle Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary brush coupling systems are inefficient as they require dismantling of the rotational shaft to replace bristles, are limited to specific types of bristles, and incur high costs and environmental impact due to complexity and lack of interchangeability.
Innovation Solution
A coupling attachment system featuring semi-circular non-superimposable mirror image parts with a male-female connection and temporary securing hooks allows for easy replacement and combination of different bristle types without disassembling from the shaft, using a catch-anchoring system and adjustable diameter for universal compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coupling attachment is formed by two non-superimposable mirror image parts with a toothed inner perimeter for pressure-fit connection, then the bristles can be securely attached to the shaft, but it is necessary to dismantle the non-superimposable mirror image parts from the rotational shaft to replace the bristles
Solution Approach 1:
The coupling attachment is divided into two non-superimposable mirror image parts that can be separated from each other and from the shaft, allowing bristle replacement without complete disassembly. The segmentation enables independent access to the bristle holding area while maintaining secure attachment during operation.
Solution Approach 2:
The coupling system transitions from a static pressure-fit connection to a dynamic system where the two parts can be easily separated and reconnected. The male-female connection with complementary shapes allows for quick assembly and disassembly operations, making bristle replacement simple and fast.
2Reliability
If the coupling attachment uses a pressure-fit connection system for bristles, then the bristles are securely held, but the bristles can only be replaced by dismantling the coupling attachment from the shaft
Solution Approach 1:
The coupling attachment is segmented into two separable parts, allowing the bristle-holding portion to be accessed and replaced independently from the shaft connection. This segmentation enables bristle replacement without time-consuming complete disassembly.
Solution Approach 2:
The two parts of the coupling attachment are pre-configured with complementary male-female connection features that enable quick connection and disconnection. This preliminary design of the connection system allows for rapid bristle replacement without extensive dismantling time.
3Reliability
If the coupling attachment is designed for one specific type of bristle, then the bristles can be securely attached, but the attachment cannot accommodate different bristle types
Solution Approach 1:
The coupling attachment is designed with a universal interface that can accommodate multiple bristle types including filaments, bands, segments, and fringes. The two-part design with standardized connection features allows the same coupling attachment to securely hold different bristle configurations for various cleaning applications.
Solution Approach 2:
The coupling system allows dynamic reconfiguration to accommodate different bristle types. The separable two-part design enables easy replacement of bristle bundles with different characteristics while maintaining secure attachment through the standardized male-female connection system.
4Ease of repair
If the coupling attachment requires dismantling the rotational shaft to replace bristles, then the bristles can be replaced, but the process requires significant time and technical service intervention
Solution Approach 1:
The coupling attachment is segmented into two separable parts that can be removed from the shaft independently, allowing bristle replacement without time-consuming shaft disassembly. This segmentation enables maintenance personnel to quickly service the brush by simply detaching and reattaching the coupling parts.
Solution Approach 2:
The simple two-part coupling design with complementary connection features enables easy self-service replacement of bristles by maintenance personnel without requiring specialized technical service intervention or complex disassembly procedures.
5Reliability
If the coupling attachment uses a complex multi-part structure, then the bristles can be securely attached, but the complexity increases the difficulty and cost of repairs
Solution Approach 1:
The coupling attachment is divided into exactly two simple parts with complementary male-female connection features, providing secure attachment without excessive complexity. This minimal segmentation achieves the balance between security and simplicity, avoiding the need for complex multi-component assemblies.
Solution Approach 2:
The two parts of the coupling attachment are designed to combine into a unified structure that securely holds the bristles while maintaining simplicity. The merging of the two parts creates a robust connection system without requiring additional complex components or assembly steps.
