Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drive systems with brakes require significant installation space and material thickness due to the use of screw connections, leading to increased space and material costs.
Innovation Solution
The implementation of pressed-in fastening elements, such as press-fit grub screws, threaded bushings, or press-in pins, which directly connect the brake to the drive system, reducing material thickness and installation space requirements while maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connections are used to connect the brake to the drive, then the connection strength is sufficient, but the installation space requirement and material thickness increase
Solution Approach 1:
The patent replaces the conventional screw connection system with a press-fit fastening element system. The press-fit elements are directly pressed into the brake component, eliminating the need for threaded holes and screw fasteners. This substitution of mechanical connection methods achieves sufficient connection strength while significantly reducing the installation space requirement and material thickness.
Solution Approach 2:
The invention extracts and eliminates the unnecessary components of the screw connection system (threaded holes, screw heads, nuts) and replaces them with a simplified press-fit element. By removing these extraneous elements, the brake achieves the same connection function with reduced material thickness and installation space.
2Reliability
If threaded holes are used for screw connections, then the connection is secure, but the material thickness requirement increases
Solution Approach 1:
The patent substitutes the threaded hole connection system with a direct press-fit element system. The press-fit elements are inserted directly into the brake material without requiring threaded holes, thereby reducing the material thickness requirement while maintaining connection reliability through the friction and interference fit of the press-fit elements.
Solution Approach 2:
The invention changes the connection parameter from threaded hole depth to press-fit element insertion depth. This parameter change allows for a reduction in material thickness because the press-fit elements achieve secure connection through radial interference and friction rather than requiring deep threaded engagement.
3Ease of operation
If through holes are used for fastening, then the brake can be connected to the drive, but additional space is required for nuts and screw heads
Solution Approach 1:
The patent extracts and removes the need for external fastening components such as nuts and screw heads by using press-fit elements that are directly pressed into the brake. This eliminates the additional space requirements for these components while maintaining the ease of connection through a simple press-fit operation.
Solution Approach 2:
The invention merges the fastening function into the brake component itself by using press-fit elements that are integral to the brake structure. This consolidation eliminates the need for separate nuts and screw heads, reducing the overall space requirement for fastening components.
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
This solution results in a more compact design with lower material costs, improved mechanical resilience, and better adaptation to magnetic requirements in electromagnetically actuated brakes, enhancing economic viability and performance in applications like machine tools and wind turbines.
Implementation Method 1
The fastening element directly connects the brake to the drive. It has been shown that when using such fastening elements, the installation space requirement and thus the material thickness requirement for connecting the fastening element to the brake is significantly lower than when using conventional fastening elements
