Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the measuring instrument is placed directly on the environment surface, then the device complexity is reduced, but the measurement precision deteriorates due to vibration transmission
Solution Approach 1:
The patent introduces a vibration damper as an intermediary component between the measuring instrument and the environment surface. This damper acts as a mediator that transmits necessary mechanical support while filtering out harmful vibrations, thus improving measurement precision without requiring complex active control systems.
Solution Approach 2:
The patent replaces complex active vibration compensation mechanisms with a passive mechanical vibration damper. This substitution uses simple mechanical elements (spring-damper system) to achieve vibration reduction, thereby maintaining device simplicity while improving measurement precision.
2Reliability
If active vibration dampers with electromagnetic actuators are used, then the reliability of vibration shielding is improved, but the use of energy increases
Solution Approach 1:
The patent implements an adaptive vibration damper system that dynamically adjusts its damping characteristics based on detected vibration conditions. The control unit modifies the damping parameters in real-time to match the actual vibration environment, ensuring reliable vibration shielding while minimizing energy consumption by avoiding unnecessary active compensation when vibrations are low.
Solution Approach 2:
The patent changes the operational parameters of the vibration damper based on environmental conditions. The control unit monitors vibration levels and adjusts the damping parameters accordingly, transitioning between passive and active damping modes to optimize both reliability and energy efficiency.
3Adaptability or versatility
If passive vibration absorbers are used, then the ease of manufacture is improved, but the adaptability to different vibration frequencies deteriorates
Solution Approach 1:
The patent transforms a static passive vibration absorber into a dynamic adaptive system. The controllable vibration damper can adjust its natural frequency and damping ratio in real-time to match different vibration excitation frequencies, providing adaptability to various operating conditions while maintaining a relatively simple mechanical structure that is easy to manufacture.
Solution Approach 2:
The patent employs periodic adjustment of the damping parameters to adapt to different vibration frequencies. The control unit periodically modifies the damper characteristics based on detected vibration patterns, enabling the system to handle a broad frequency range while maintaining a simple manufacturable design.
