Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shock absorbing devices are used, then vibration reduction function is provided, but device complexity and manufacturing cost increase
Solution Approach 1:
The shock absorbing device is divided into independent functional modules: mounting seat, supporting components, and resilient assemblies. Each module performs a specific function (mounting, supporting, or shock absorption), allowing for simplified individual component design and easier assembly/disassembly while maintaining overall vibration reduction effectiveness
Solution Approach 2:
The mounting seat is movably disposed inside the case, and the resilient assembly is disposed inside the mounting seat, creating a nested structure where smaller components are housed within larger ones. This nested arrangement reduces overall device complexity by integrating multiple functions into a compact hierarchical structure
2Reliability
If conventional shock absorbing devices are used, then vibration reduction function is provided, but manufacturing cost increases
Solution Approach 1:
By segmenting the device into standardizable modules (mounting seat, supporting components, resilient assemblies), each module can be manufactured independently using optimized processes and then assembled, reducing overall manufacturing cost through modular production and enabling easier replacement of wear-prone components
Solution Approach 2:
The resilient assembly, which is subject to wear and degradation from repeated shock absorption cycles, is designed as a replaceable component. When it deteriorates, only this specific component needs replacement rather than the entire device, reducing long-term manufacturing and maintenance costs
3Stability of the object's composition
If conventional shock absorbing devices are used, then structure is provided, but suitability for high frequency vibration environment decreases
Solution Approach 1:
The mounting seat is designed to be movably disposed inside the case, allowing it to dynamically adjust its position in response to vibration inputs. The resilient assembly provides dynamic shock absorption by elastically deforming under load and recovering when the load is removed, enabling the device to adapt to varying vibration frequencies and intensities while maintaining structural stability
Solution Approach 2:
The resilient assembly changes its mechanical parameters (stiffness, damping) in response to applied loads and vibration frequencies. This parameter adaptation allows the shock absorbing device to effectively handle high-frequency vibrations by adjusting its response characteristics based on the input vibration conditions

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 device effectively reduces vibrations, preventing fuzzy images while maintaining a low manufacturing cost and suitability for high-frequency vibrations, thus addressing the limitations of prior art.
Implementation Method 1
The resilient assembly includes at least one first resilient component and at least one second resilient component. The at least one first resilient component is located between the mounting seat and the first supporting component. The at least one second resilient component is located between the mounting seat and the case.
