Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional rigid drawbar bracket is used, then the structural strength is sufficient, but vibration transmission from the work vehicle body to the drawbar is excessive
Solution Approach 1:
The patent introduces curved parts (first curved part and second curved part) in the fastening plates instead of rigid straight connections. These curved portions act as flexible elements that can deform under vibration loads, absorbing vibrational energy while maintaining the overall structural strength of the bracket assembly.
Solution Approach 2:
The patent changes the structural parameters of the fastening plates by incorporating curved geometries and strategic openings. This modifies the stiffness distribution and stress flow paths, allowing the bracket to maintain strength while reducing vibration transmission through controlled flexibility in specific regions.
2Object-affected harmful factors
If the bracket structure is made more flexible to reduce vibration, then vibration transmission is suppressed, but the structural strength may be compromised
Solution Approach 1:
The bracket is divided into multiple components (first fastening plate, second fastening plate, coupling member) with curved parts strategically positioned. This segmentation allows different regions to have different functional characteristics - some areas provide flexibility for vibration suppression while others maintain rigidity for structural reliability.
Solution Approach 2:
The curved parts act as intermediary elements between the rigid fastening plates and coupling members. These curved portions serve as flexible mediators that transmit loads while absorbing vibrational energy, protecting the overall structure from vibration-induced fatigue and failure.
3Object-affected harmful factors
If additional components are added to suppress vibration, then vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
The vibration suppression function is merged into the existing fastening plates by incorporating curved parts directly into their geometry. This integration approach eliminates the need for separate vibration isolation components, reducing overall device complexity while achieving vibration suppression.
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 design effectively suppresses vibration transmission from the work vehicle body to the drawbar, increasing the strength and flexibility of the bracket while preventing interference, thus enhancing operational stability and reducing wear and tear.
Implementation Method 1
The first curved part links the first plate body to the first fastening part and has a curved shape. The second curved part links the second plate body to the second fastening part and has a curved shape. Accordingly, at least one of the first curved part and the second curved part can suppress transmission of vibration input from the work vehicle body
