Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fastening systems for cylindrical tools on drive shafts require multiple designs to accommodate different drive shaft diameters, leading to high manufacturing costs and complexity, as tools need to be specialized for specific machines, and there is a need for a reusable adapter that can securely attach various tools to any drive shaft.
Innovation Solution
A fastening adapter with a hollow-cylindrical base and elastic lamellae that can be compressed and expanded to securely attach cylindrical tools, featuring a fastening device adaptable to different drive shafts, with lamellae tilted to stabilize the tool during operation and prevent slipping, using materials like rubber or polyurethane for optimal compression and vibration reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specialized fastening device is designed for each drive shaft diameter, then the tool can be securely attached to the specific drive shaft, but the manufacturing complexity and costs increase significantly
Solution Approach 1:
The fastening adapter is designed with a universal structure that can accommodate multiple drive shaft diameters through adjustable clamping mechanisms. The adapter body includes a standardized interface that can adapt to different shaft sizes, eliminating the need for multiple specialized fastening devices while maintaining secure attachment reliability
Solution Approach 2:
The fastening adapter incorporates adjustable parameters such as variable clamping force, adjustable clamping position, and modular components that can be configured for different drive shaft diameters. This allows a single adapter design to serve multiple functions across different machine configurations, reducing manufacturing complexity while preserving secure attachment capabilities
2Reliability
If multiple specialized fastening devices are manufactured for different drive shafts, then each tool can be optimized for specific machines, but the manufacturing costs increase
Solution Approach 1:
The fastening adapter employs a universal design philosophy where a single standardized adapter body can be used across multiple drive shaft configurations. This reduces the number of unique parts that need to be manufactured, thereby lowering manufacturing costs while maintaining reliable attachment through proven design elements
Solution Approach 2:
The fastening adapter is divided into modular segments including a standardized adapter body, adjustable clamping components, and interchangeable interface elements. This segmentation allows for economical manufacturing of individual modules that can be assembled in various configurations, reducing overall manufacturing costs compared to producing entirely specialized fastening devices for each application
3Adaptability or versatility
If tools are manufactured with different passage opening designs for various drive shafts, then compatibility with specific machines is achieved, but the manufacturing complexity and costs increase
Solution Approach 1:
The fastening adapter serves as an intermediary component between the standardized tool passage opening and the varied drive shaft interfaces. This mediator approach allows tools to maintain a uniform passage opening design while the adapter adapts to different drive shaft configurations, thereby maintaining compatibility without increasing tool manufacturing complexity
Solution Approach 2:
The adapter incorporates a universal passage opening interface that can accommodate multiple drive shaft types through adjustable and reconfigurable components. This universal design enables a single tool design with standardized passage openings to be compatible with various drive shaft configurations, reducing the need for multiple specialized tool variants
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapter provides a stable, reusable fastening solution that prevents tool slippage and vibration, ensuring secure attachment and reducing manufacturing costs by allowing a single adapter to fit various drive shafts, while maintaining friction and stability during operation.
Implementation Method 1
The outer diameter of the fastening adapter can be elastically reduced by exerting pressure or by applying a shearing force in the direction of tilting on the slats. The compression of the fastening adapter is essentially achieved by reducing the size of the cavities between the lamellae
Implementation Method 2
When the pressure or shearing forces are removed, the lamellae expand again and assume their original shape and orientation. The fastening adapter then has its original diameter again
Implementation Method 3
The lamellae are in their direction perpendicular to the cylinder axis each tilted by a predetermined angle relative to the radial direction. The direction in which the lamellae abut one another is already predetermined and exerting pressure on the ends of the lamellae is sufficient to press the lamellae against one another

AI summary
The system has a fastening device arranged within a hollow-cylindrical base (11). The base coming out from the fastening device around a cylindrical axis (13) divides fins (15), where the fins are arranged at a distance from each other by slots (14). The fins are tilted in a direction perpendicular to the cylindrical axis around a preset angle opposite to a radial direction. The fins are tilted in a moving direction preferred during operation of a roller-shaped tool e.g. foreman roller, where a passage opening of the tool is rigidly and cylindrically designed. Independent claims are also included for the following: (1) a fastening adapter for use in a fastening system (2) a method for mounting a roller-shaped tool at a drive shaft of a drive engine.
