Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shock absorber structures with multiple springs are used to absorb vibrations in multiple directions, then vibration absorption capability is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The patent combines horizontal and vertical shock absorber assemblies into a single integrated structure sharing common components (main body assembly, elastic elements, damping elements), reducing overall complexity while maintaining multi-directional vibration absorption capability
Solution Approach 2:
The shock absorber structure is designed with universal features including adjustable stiffness elastic elements, replaceable damping elements, and modular assemblies that can be adapted to different machines and working environments, providing multi-functional capability
2Force
If shock absorber assemblies are designed to bear large loads, then load-bearing capacity is improved, but the assemblies tend to separate during operation requiring large installation space
Solution Approach 1:
The patent employs nested design where the slide shaft rotates inside the slide tube, the first bushing surrounds the centering shaft, and the second bushing is positioned within the vertical shock absorber assembly, allowing compact configuration that maintains load-bearing capacity while reducing installation space
Solution Approach 2:
The transition cam rotates around a cam axis perpendicular to both horizontal and vertical assemblies, utilizing three-dimensional spatial arrangement to connect load-bearing assemblies without requiring large separation distances
3Reliability
If shock absorber structures are designed for specific machine configurations, then vibration absorption effectiveness is improved, but adaptability to various machines and working environments decreases
Solution Approach 1:
The patent incorporates adjustable stiffness elastic elements and replaceable damping elements that can be modified according to different working conditions and machine types, providing dynamic adaptability while maintaining vibration absorption effectiveness
Solution Approach 2:
The shock absorber is divided into modular assemblies (horizontal assembly, vertical assembly, main body assembly) with standardized interfaces, allowing flexible configuration and adaptation to different machine applications
4Stability of the object's composition
If shock absorber components are integrated into a fixed structure, then structural stability is improved, but ease of maintenance and replacement decreases
Solution Approach 1:
The patent designs modular assemblies (horizontal shock absorber assembly, vertical shock absorber assembly, main body assembly) with standardized connection interfaces, maintaining structural stability while enabling easy disassembly, maintenance, and replacement of individual 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
The structure effectively absorbs vibrations in multiple directions, supports heavy loads, and is easily adaptable to various machines, ensuring stability and ease of maintenance and repair.
Implementation Method 1
The first elastic element is arranged around the spring shaft, so its rotation causes deformation of the first elastic element
Implementation Method 2
The second elastic element is arranged around both bushings to deform when either bushing moves
Implementation Method 3
a slide shaft that can rotate inside the slide tube
Implementation Method 4
The centering shaft, located inside the first bushing, interlocks with its inner surface, allowing the first bushing to pull the centering shaft in one direction and slide along its surface in the opposite direction
