Large scanning beds and office equipment lids pose safety risks and operational strain due to weight. Managing gravitational force during opening and closing prevents equipment damage and user injury.

Mechanical misalignment and asynchronous movement between multiple axes during folding. Ensuring uniform rotation prevents structural stress and display damage in foldable electronics.

Mechanical fatigue or misalignment in switchgear hinges leads to poor contact force. Maintaining high pressure prevents overheating and electrical arcing during high-current switching.

Abrupt closing of heavy office equipment lids causes mechanical shock and noise. Preventing high-velocity impact reduces component wear and structural damage.
