Three-Aperture Rotary-Carousel Air-Pulse Stimulator with Round, Deep-Oval and Wide-Shallow Seals

Select among three seal geometries on one rotary carousel

This three-aperture rotary-carousel air-pulse stimulator concept places one small round opening, one tall deep oval and one wide shallow oval on a single smoky-plum head disc. A guarded centre pivot, three rim index notches, two handle buttons and one thumb cradle complete the visible architecture.

The image defines a visual proposal only. Air routing, seal performance, materials, controls, battery and ingress protection remain pending engineering evidence.

Keep the sales unit to one integrated device

The planned pack contains exactly one handheld unit. Detached cups, spare seals, a remote, phone application, charging cable, adapter, dock, storage case and cleaning brush are excluded unless the approved packing list changes.

All three seal shapes are integrated into the carousel rather than supplied as loose attachments.

Validate carousel rotation indexing and retention

Measure disc diameter, thickness, rotation torque, axial play, runout and stop alignment. Cycle the selector through every position under dry and approved wet-cleaning conditions, checking false seating, drift, seizure and wear.

The disc must not rotate unexpectedly during operation, but no lock or one-handed selection claim is made before testing.

Measure the small round seal as opening A

Record A’s inner diameter, rim width, recess depth, edge radius and local hardness. Map pressure and leakage under several controlled contact loads without assuming that the smallest opening creates the strongest sensation.

Fit and intensity depend on geometry, compliance and pump behaviour, all still unverified.

Characterise the tall deep oval as opening B

Measure B’s major and minor axes, tunnel depth, taper and rim profile at multiple points. Inspect the deep recess for mould seams, cleaning access and complete drying after repeated cycles.

No anatomy-specific fit claim is made.

Characterise the wide shallow oval as opening C

Record C’s horizontal span, vertical span, shallow depth, lip thickness and curvature. Compare contact area, leakage and pressure waveform with A and B under the same instrumented conditions.

Wide or shallow does not imply gentler performance until measured.

Route only the selected aperture through the centre pivot

Request internal air-channel drawings and teardown representative samples to verify how the guarded centre port connects to each carousel position. Test isolation between inactive openings and inspect seals for cross-leakage.

Single-pump, valve type, replaceable filter and serviceability claims remain pending.

Use three rim notches as alignment cues

One charcoal notch sits near each proposed position. Specify notch depth, spacing, tactile contrast and relationship to the active airway, then verify that users can identify full alignment without seeing the head.

The notches are cues only and do not prove a mechanical detent.

Define the two-button control map through firmware tests

Document power timing, short and long presses, sequence changes, status feedback, memory, travel lock and low-battery behaviour after firmware is fixed. Check accidental activation inside the planned packaging.

Mode count, independent pressure levels and pause behaviour remain unconfirmed.

Shape the thumb cradle around measured grip reach

Measure handle circumference, mass, balance, button reach and cradle dimensions across multiple adult hand sizes. Evaluate wet and dry grip without relying on the colour insert as proof of slip resistance.

Users should stop if holding the device causes numbness, strain or loss of control.

Map pressure waveforms for all three carousel positions

Log peak, minimum, average and frequency values for A, B and C across every verified setting and contact load. Include leakage, recovery time, pump temperature and sample variation.

Air-pulse, suction, quietness and intensity claims remain withheld until a complete production-representative device passes the test plan.

Set conservative external-use and stop conditions

Use only on intact external skin after verifying cleanliness and material compatibility. Begin at the lowest confirmed setting, maintain continuous consent and remove the device immediately for pain, numbness, swelling, discoloration, bleeding, unusual heat or difficulty breaking the seal.

The unit is not intended for internal insertion and is not a medical, diagnostic or therapeutic device.

Verify battery charging transport and fault protection

Request cell chemistry, rated capacity, charging input, charge time, runtime method, low-voltage cut-off, over-current protection, temperature limits and transport documents. Cycle multiple samples while logging capacity and enclosure temperature.

Cable type, cable inclusion, runtime, standby and fast-charge claims remain pending.

Test materials seams ingress and carousel cleaning access

Obtain traceable composition, hardness, pigments, adhesives, lubricants and restricted-substance evidence for the body, cradle, carousel, three rims, pivot, buttons and internal seals. Test the complete assembled rotating head for liquid ingress rather than relying on component claims.

Silicone, ABS, phthalate-free, latex-free, hypoallergenic, body-safe and waterproof claims remain withheld. Clean and dry all three recesses, the pivot and rim notches only by a validated method; stop using the device for cracks, tackiness, loose parts, corrosion, erratic output or trapped residue.

Price from public air-pulse benchmarks and selector validation

An Alibaba air-pulse category page displayed mini devices at USD 7.29 to 8.69 with MOQ 2, a rechargeable reference at USD 8.06 to 8.50 with MOQ 1 and a replacement-cover reference at USD 5.08 to 5.80 with MOQ 1. These are broad examples, not quotations for this rotary three-aperture proposal or approved suppliers.

The public procurement benchmark supports an EUR 59.99 planning price after provisional allowance for China-origin freight, custom carousel and three seal cavities, index and routing tests, three-position pressure mapping, pump, battery and ingress validation, cleaning access, discreet fulfilment and expected electronic quality loss. Exact supplier, quote, MOQ, dimensions, materials, packed weight, freight, duty, tax, certification, payment terms, lead time and production availability remain pending.

Frequently asked questions about the three-aperture carousel

How many openings are built into the head?

Exactly three recessed openings are proposed on one integrated rotating disc.

What shapes are included?

The concept shows one small round opening, one tall deep oval and one wide shallow oval.

Are separate cups included?

No. The planned single-device inventory excludes detached cups and spare rings.

Does the carousel lock into position?

Indexing and retention are design intentions, but torque, detents and drift remain pending mechanical tests.

Is the device waterproof?

No ingress claim is made until the complete rotating assembly passes a documented test.

Does each opening feel different?

Geometry differs visibly, but pressure waveform and perceived output require controlled measurements and qualified evaluation.
