Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If fluid damping is used to damp pitch and rotational oscillatory motions, then damping effectiveness is improved, but reliability deteriorates due to fluid spilling or migration onto adjacent parts
Solution Approach 1:
The patent replaces the mechanical fluid damping system with a magnetic damping system. Instead of using silicone fluid that requires containment, the invention uses magnets positioned near conductive plates to generate eddy currents that provide damping forces. This substitution eliminates the reliability issues associated with fluid containment while maintaining effective damping of pitch and rotational oscillations.
2Ease of operation
If magnetic damping is used to damp oscillatory motions, then ease of operation is improved, but damping effectiveness deteriorates compared to fluid damping
Solution Approach 1:
The patent optimizes the parameters of the magnetic damping system to achieve effectiveness comparable to fluid damping. This includes carefully selecting magnet positions, sizes, and strengths, as well as optimizing the conductivity and dimensions of the plates. By adjusting these parameters, the system achieves sufficient damping force while maintaining the ease of operation and reliability advantages of magnetic damping over fluid damping.
