Cavity Massage TRIZ Cases

Rotating acupressure plates in the chair backrest deliver spine correction and massage with minimal armrest movement, even in tight spaces.

Opposed current paths on both sides of an insulated panel cancel low-frequency EM fields while preserving infrared sauna heating.

Alternating two button cells through MOSFETs and a DC-DC converter cuts motor power draw and extends safe vibration time.

An internal nail cavity and solid barrier contain long fingernails to prevent tissue injury and nail dislodgment during penetration.

A movable tapping body in an accommodating cavity boosts tapping force under pressure while reducing unwanted vibration and improving localized massage.

A layered silica gel sleeve and air-locking structure preserves swelling, prevents leakage, and maintains vibration force without rupture.

A bistable push-push mechanism lets a water-powered shower head switch vibration on or off without interrupting water flow.

A curved internal cavity nests and constrains the finger to prevent dislodgement while improving comfort and stable positioning during use.

A driven-wheel massage head expands stimulation area by adding rotating kneading motion, improving massage effect over localized beating.

Flexible engagement portions and a swing-arm drive help keep the massager in place while delivering clamping and vibrating massage.

An elastic spring, rotatable massage member, and height adjustment mechanism vary pressure and improve comfort without a reciprocating chair.

One driving device synchronizes claw-arm swinging and telescopic-base motion for multi-point stimulation while reducing mold costs.

An integrated LED treatment body uses 600–750 nm light and low irradiance for comfortable home photobiostimulation.

A motorized prostate massage roller and height-adjustable guide replace manual movement, varying pressure for adaptive massage.

Flexible neck and motorized vibration enable accessible, self-administered prostate stimulation.

Controlled heat and vibration liquefy meibum to support tear-film lipid restoration.

Replacing mechanical linkages with magnetic fields, the device positions a stimulation element to resolve complexity versus adaptability trade-offs.

A pelvic floor exercise device uses external weights to impose variable resistance on muscle contraction.

A flexible physical stimulation device uses an open elevated section and removable insert to accommodate diverse anatomies.

A user accessory translates physical body movements into digital game inputs to enhance player engagement.

An inclined expansion fastener opens elastic sheets to expand the massager head diameter, addressing limited skin contact area in standard devices.

Segmented spray nozzles expand treatment area while integrated sensors monitor vitals and collect sweat for clinical analysis.

Internal vibration from an ingestible capsule stimulates intestinal walls, bypassing thick abdominal tissue that blocks external devices.

Segmented control assembly with flexible connectors prevents tilting from component height variations, ensuring coaxial alignment and improving yield rates.

A vibrating gastrointestinal capsule stimulates peristalsis to enhance medicament absorption within the digestive tract.

Wall-mounted unit combines thermal, visual, and audio treatments to replace bulky, technician-dependent systems with user-controlled therapy.

Flat USB plug integrates charging electrodes and PCB antenna to resolve liquid penetration risks while enabling Bluetooth connectivity.

Alternating rotational massage units stimulate oral muscles at 18-30 Hz to strengthen soft palate tissue without triggering gag reflexes.
