Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for control devices on agricultural machines are complex, labor-intensive to assemble and disassemble, and do not adequately decouple the control devices from vibrations and oscillations, particularly in areas with limited accessibility like near drive motors.
Innovation Solution
A simplified fastening arrangement using a holding element with a fastening web and a support element featuring buffer elements on both sides, allowing for easy assembly and disassembly from one side, with a U-shaped design to reduce vibrations and oscillations, and incorporating recesses for secure buffer element placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-part fastening system with vibration-damping elements is used to decouple the control unit from vibrations, then the control unit is protected from vibrations and shocks, but the assembly and disassembly become extremely complex and labor-intensive due to the multitude of individual parts and fastening devices located at different levels
Solution Approach 1:
The patent combines multiple fastening elements and vibration-damping components into a single integrated fastening device. The fastening device includes a first fastening element, a second fastening element, and a third fastening element that are interconnected to form one unified component that can be installed and removed as a single unit, eliminating the need to manually assemble multiple separate parts.
Solution Approach 2:
The integrated fastening device serves multiple functions simultaneously: it provides vibration damping through integrated damping elements, secures the control unit through multiple fastening points, and enables easy installation/removal through a single操作 interface. This multi-functional design resolves the contradiction by making one component do the work of several separate components.
2Stability of the object's composition
If control units are screwed or anchored directly to body elements to prevent relative movements, then the control units are securely fastened, but excessive vibrations are transmitted to the control units due to the movements of the vehicle
Solution Approach 1:
The patent introduces vibration-damping elements as intermediary components between the control unit and the vehicle body. These damping elements are integrated into the fastening device and serve as a mediator that absorbs and dissipates vibration energy, preventing direct transmission of harmful vibrations to the control unit while maintaining secure mechanical attachment.
Solution Approach 2:
The fastening device incorporates composite construction with elements of different material properties - rigid fastening components for secure attachment and vibration-damping materials (such as elastomers or viscoelastic materials) for vibration isolation. This composite approach allows simultaneous achievement of stable mounting and vibration protection.
3Reliability
If a multi-part fastening system is used to provide vibration decoupling, then vibration protection is achieved, but accessibility to the control unit is limited and assembly/disassembly requires working at different levels which is extremely complex
Solution Approach 1:
The patent merges multiple fastening elements, vibration-damping components, and connection elements into a single integrated fastening device. This consolidation reduces the number of individual parts from multiple separate components to one unified device, simplifying the overall system while maintaining vibration decoupling functionality.
