Varying transparent cover thickness creates a durable gradient effect that avoids printed-layer detachment, vibration wear, and allergy risk.
Reciprocating rollers driven by gears and an eccentric groove massage the entire foot sole automatically, improving coverage without user effort.
A single motor and dual transmission parts create rotational and reciprocating massage motions in a compact structure that lowers complexity and cost.
A helical cam, reciprocating driveshaft, and compression spring cut interference and improve energy transfer in a low-cost personal acoustic wave tip.
A wearable vibration unit combines adjustable power and frequency settings with visual feedback to simplify acupressure stimulation and hygiene.
A telescoping handle secures percussive massage devices, improves back access, and shifts device weight for steadier force and muscle relaxation.
Independent and combined pendulum oscillators create high- and low-frequency stimulation while a cushioning member limits handle vibration.
Dual eye treatment units combine heat, vibration, audio, and biometric feedback to deliver personalized bilateral stress relief in a compact wearable form.
Opposed swing arms with elastic wrappers deliver synchronous multi-directional percussion, avoiding repeated device reorientation.
An eccentric shaft and guided pushing member create precise local vibration massage while bearings cut frictional loss and improve motion stability.
A rotating massage member expands contact area and delivers continuous gentle kneading to restore pelvic floor muscles without secondary injury.
An encircling penile stimulator uses reciprocating tapping and vibration to expand stimulation modes, improve comfort, and reduce detachment risk.
Cooling and fan-assisted airflow add post-exercise relief to enclosed foot massage, reducing stuffiness, humidity, and muscle tension.
Subtle wrist motions replace obvious app or button control, enabling discreet remote toy activation through inertial sensing.
