Four-Spoke Concentric-Oval Couples Ring with Crescent Twin-Pad Pod and Sliding Lower Clasp

Nest two oval loops inside a four-spoke couples ring

This four-spoke concentric-oval couples ring concept uses one smoky-plum outer loop and one smaller inner loop. Exactly four charcoal radial spokes hold the spacing, while a crescent pod carries two raised contact pads and a lower slider closes the outer perimeter.

The rendering defines geometry only. Materials, dimensions, stretch, clasp behaviour, output, charging and ingress protection remain pending.

Keep the inventory to one integrated device

The planned sales unit contains exactly one powered ring. A remote, phone application, charging cable, adapter, sleeve, lubricant, storage case and spare clasp are excluded unless the approved packing list adds them.

All electronics shown are integrated into the crescent pod rather than supplied as a detachable bullet.

Set the outer oval as the main flexible perimeter

Measure relaxed major axis, relaxed minor axis, cross-section, stretched axes and force versus extension. Repeat the measurements after conditioning and use cycles to identify permanent set, thinning or asymmetric recovery.

No universal fit range is promised until tested dimensions and safe extension limits are available.

Centre the smaller inner oval without contact bridges

Record inner-loop axes, wall diameter and spacing from the outer loop at top, bottom and both sides. Confirm that the nested loop stays centred under equal and uneven loads without folding through the outer opening.

The two loops are concentric in the design and are not separate removable rings.

Join the loops with exactly four radial spokes

Place one short spoke at top, bottom, left and right. Specify width, thickness, fillet radius and stiffness for each connection, then cycle them individually and together to assess tearing, twist and force transfer between loops.

No diagonal or fifth spoke is included.

Span the top with one crescent powered pod

Measure pod width, height, curvature, mass and attachment area. Inspect how the rigid or semi-rigid enclosure meets the flexible outer loop, especially after bending, charging and repeated cleaning.

Motor count, removable construction and independent channels remain unconfirmed.

Separate two raised oval contact pads

Record pad length, width, height, edge radius, spacing and surface hardness. Measure output at both pads under free and controlled loads to determine whether they behave equally or transmit different amplitudes through the crescent shell.

Exactly two pads are proposed; neither should expose a seam or hard enclosure edge.

Validate the lower sliding clasp before calling it adjustable

Define travel range, detents, pull direction, opening procedure and retention force. Test one-handed release under dry and lubricated conditions without allowing the slider to pinch skin or separate unexpectedly.

The clasp is a design concept only; adjustability and quick-release claims remain withheld until verified.

Publish ring dimensions with conservative use limits

List relaxed and extended loop measurements, product mass, pod dimensions and clasp travel. Determine maximum continuous wear time and mandatory removal conditions through risk assessment and qualified review rather than copying a generic ring limit.

Remove immediately if pain, numbness, coldness, discoloration, swelling or difficulty releasing the device occurs, and seek urgent medical help if it cannot be removed.

Map output through pads loops and spokes

Measure frequency, acceleration and amplitude at both pads, each spoke and both loops across every verified setting. Test under multiple controlled loads because the concentric frame can redistribute vibration as it stretches.

Intensity, quietness, dual-zone and mode-count claims remain pending measured evidence.

Define the single control through firmware tests

Record power-on timing, short-press sequence, long-press behaviour, status feedback, memory, travel lock and low-battery indication only after firmware is fixed. Check accidental activation inside the planned packaging.

Remote control, application control and partner control are not promised.

Validate battery charging and fault protection

Request cell chemistry, rated capacity, charge input, charging time, runtime method, low-voltage cut-off, over-current protection, transport documents and storage guidance. Cycle several production-representative samples while logging temperature and capacity loss.

Cable type, cable inclusion, runtime and standby duration remain pending.

Verify materials seams and ingress across mixed stiffness

Obtain composition, hardness, pigments, adhesives and restricted-substance documentation for loops, spokes, pads, pod, clasp and control. Inspect every material transition before and after extension and cleaning cycles.

Silicone, ABS, phthalate-free, latex-free, hypoallergenic, body-safe and waterproof claims remain withheld without traceable evidence and complete-device tests.

Set cleaning storage and failure checks

Clean around both pads, all four spokes, the inner loop and the lower slider only with methods compatible with confirmed materials and ingress limits. Dry every recess, inspect the clasp and stop use if cracks, tackiness, loose parts, unusual heat or erratic output appears.

Do not share without an appropriate barrier and validated cleaning process. Medical, erection and delay claims are not made.

Plan price from vibrating-ring benchmarks and landed reserves

An Alibaba vibrating-ring page displayed a rechargeable full-silicone reference at USD 5.90 to 6.53 with MOQ 16. A vibrating-cock-rings page displayed references at USD 4.80 to 5.00 with MOQ 50, USD 6.37 to 6.67 with MOQ 1 and USD 7.48 to 7.87 with MOQ 3. These are broad category examples, not quotations for this four-spoke concentric design or approved suppliers.

The public procurement benchmark supports an EUR 42.99 planning price after provisional allowance for China-origin freight, custom nested-loop moulding, four-spoke fatigue tests, clasp and pad validation, battery and ingress checks, discreet fulfilment and expected electronic quality loss. Exact supplier, quote, MOQ, dimensions, materials, motor, battery, packed weight, freight, duty, tax, certification, payment terms, lead time and production availability remain pending.

Frequently asked questions about the concentric-oval couples ring

How many oval loops are included?

Exactly two nested loops are proposed, one outer and one smaller inner oval.

How many spokes connect the loops?

Exactly four short spokes sit at the top, bottom, left and right positions.

Does it include a remote?

No. The planned single-device pack excludes a separate remote.

Is the lower clasp quick release?

Release direction, force and reliability remain pending physical safety tests.

Is the ring waterproof?

No ingress claim is made until the complete charged enclosure passes a documented test.

What material is used?

No loop, pad, spoke or pod material has been verified, so material claims remain pending.
