Contact Vibration/Shock Damping TRIZ Cases

Vents in the drive chamber provide position-dependent damping for a Thomson coil plunger, reducing rebound and mechanical stress.

A mechanical LED switch uses a movable polymer body to absorb kinetic energy, preventing electrode bouncing and arc formation caused by high inrush currents.

An elastic damping element cushions the base body impact on the plunger, preventing relay damage and maintaining tripping accuracy.

Hydraulic shock absorbers constrain the opening speed of vacuum interrupters, preventing mechanical damage and extending service life.

A relay housing uses deformable connecting parts to absorb shock and vibration stresses while maintaining a lightweight structure.

Thomson coils drive the rod while a solenoid damper provides active damping to reduce contact bounce and wear.

A stamped-bent catch spring absorbs kinetic energy from a moving contact slide, preventing rebound that causes contact fusion and device failure.

Segmented barriers in the gas channel manage flow resistance and deceleration to resolve turbulence and vibration issues while maintaining mechanical stability.

Segmented control device uses compression spring between adjusting member and base to eliminate tolerance stack-up during assembly.

A leaf spring seat absorbs ram impact energy through controlled elastic deformation.

An annular mass in the contact spring assembly generates hammer-blow impact force to open welded vacuum interrupter contacts.

A sound insulating gap and lengthened propagation path reduce collision noise in electromagnetic relays without increasing part count.

A cylindrical bellows support member contacts the accordion portion to prevent deformation.

A vacuum interrupter damper uses a piston and blocking structure to control shaft movement, preventing arcing and improving contact switching reliability.
