Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical shock absorbers are used, then shock absorption function is provided, but precise radial recentering cannot be guaranteed and mechanical friction reduces component quality
Solution Approach 1:
The patent replaces traditional mechanical friction-based shock absorbers with a magnetic field-based system. Magnetic polar masses generate magnetic fields that interact with magnetizable components to provide both shock absorption and precise radial recentering without mechanical contact, thereby eliminating mechanical friction during normal operation while ensuring exact recentering after shocks.
Solution Approach 2:
The patent introduces magnetic polar masses as intermediary elements between the shock-absorbing component and the component being protected. These polar masses generate magnetic fields that mediate the shock absorption process, providing both protective function and precise positioning without direct mechanical contact.
2Object-affected harmful factors
If mechanical friction is used for shock absorption, then shock protection is achieved, but component efficiency and quality factor decrease during normal operation
Solution Approach 1:
The patent substitutes mechanical friction with magnetic field interactions for shock absorption. The magnetic polar masses create magnetic fields that interact with magnetizable components to provide shock protection without the energy-dissipating friction that characterizes traditional mechanical systems, thereby maintaining higher component efficiency during normal operation.
Solution Approach 2:
The patent changes the fundamental interaction parameter from mechanical friction to magnetic field strength. By adjusting the magnetic field parameters of the polar masses, the system achieves shock absorption through magnetic interactions rather than friction, reducing energy loss while maintaining protective function.

AI summary
The device (10) has a guiding unit or attracting unit provided on two sides of ends (2, 3), where the guiding or attracting unit guides pivoting of one of the ends or attracts the end to maintain the end abutting on a pole piece (4). Another guiding unit or attracting unit is provided in proximity to another pole piece (6) for guiding the pivoting of another end or attracting the latter end towards the latter pole piece. The former and latter guiding or attracting units move along an axial direction (D) between stop members. A viscous friction damping unit dampens the movement of the pieces. An independent claim is also included for a magnetic and/or electrostatic pivot, comprising a timepiece component.
