Stuffed Mattresses TRIZ Cases

Independently pressurized chambers, side supports, and a lower-extremity wedge keep anatomy aligned with pressure-relief zones to reduce ulcers.

Alternating bladder pressure during bed angle changes lowers occupant shear stress and tissue stretch while maintaining support.

Interchangeable torsion spring rakes in mattress channels let firmness zones be tuned for user weight, pressure distribution, and comfort.

Temperature-controlled airflow through a mattress air chamber warms patients during surgery while preserving pressure relief and surgeon access.

A breathable hammock cover over a contoured mattress improves infant airway openness while reducing skull pressure and supporting burn care airflow.

A bottom fire-resistant laminate and enclosing sock create a char barrier that cuts heat release while avoiding higher mattress manufacturing cost.

Soft and hard foam layers in a tubular spring create strain-hardening support that fits different body weights without losing comfort.

Interconnected panels and a wrap-around fastener enclose under-seat storage and turn a collapsed chair into its own carry bag.

Open angled members, wire mesh, and a seamless foam mattress remove hidden spaces, making beds easier to inspect, clean, and keep bedbug resistant.

Conditioned air or fluid is routed through recessed bed zones to heat or cool the sleeper directly, improving comfort without conditioning the whole room.

A tapered chest support compresses into an inverted arc to unload the injured shoulder and keep the spine aligned during side sleep.

Insert materials embedded in a fiber composite seat cushion create soft and firm zones plus ventilation while avoiding costly foam lamination.

A four-layer absorbent lift pad keeps skin dry, blocks leakage, allows airflow, and stays strong enough to reposition patients when wet.

Variable flute formation between foam substrates creates 3D mattress support while avoiding costly roller changes and handling low-plasticity materials.

Independently pressurized chambers and side supports keep vulnerable anatomy aligned with pressure-relief zones to reduce ulcer risk.

A standardized manifold, faceplate, and programmable board let one air mattress pump fit different zone counts while cutting cost and inventory.

A fabric sleeve preloads the coil spring without loading telescoping members, eliminating stickiness, popping noise, and spacer dependence.

Apertured crib bumper pads increase airflow while staying securely attached and supported to prevent sagging, wedging, and suffocation risk.

A contoured trunk and head rest with a cantilevered arm cavity relieves joint pressure and keeps the spine aligned during side sleep.

A pressure-sensitive diaphragm triggers switches to stop an air bladder pump at threshold pressure, preventing motor burnout and user monitoring.

A movable siderail handle stores within the panel edge and deploys outward to give patients a secure grip during bed entry and exit.

A mesh crib bumper with an integrated teething rail cover improves airflow, secure attachment, and easy cleaning in one assembly.

Channel-shaped mattress and bed deck covers stay attached on adjustable beds while silver-ion antimicrobial layers reduce contamination.

Sealed air cells with pump and valve control hold set pressure, reducing patient shift and bedsore risk during surgery.

Sealed wheelchair air cells use pump-and-valve setpoint control, then lock pressure changes to avoid patient movement during procedures.

Layered vapor-permeable and air-control materials move moisture and heat away from bed patients to help prevent decubitus ulcers without powered airflow.

Dual-density fiber padding over pocketed springs replaces foam to retain support, reduce flammability, and simplify cushion assembly.

Foam protrusions and gel-filled channels create firmer body support with lower weight, better comfort, and reduced material cost.

A pocketed spring core wrapped in dual-density fiber replaces most foam to keep support stable, cut labor, and improve recyclability.

A segmented beach towel uses hook-and-loop fasteners to expose or conceal a non-absorbent mesh section while keeping absorbent upper and lower panels.

A perimeter air chamber reinforces multi-chamber mattress edges to limit sagging, improve access, and reduce roll-off risk.

By merging the blower chamber and deflation port into one housing, this case cuts mattress assembly steps, cost, and leak risk.

Independently inflatable chambers adjust abdomen cavity depth, firmness, and leg position to support changing pregnancy body shapes.

Surface-modified wet gel and solvent exchange enable ambient-dried silica aerogel mats with less shrinkage, flaking, and fiber damage.

A spring-loaded sliding bracket keeps a mattress aligned on an adjustable base while reducing gaps and overhangs in different positions.

An air-film transfer sled reduces friction and surface-gap instability to keep patient orientation and treatment applicator position stable.

Offset interior welds and middle-layer gaps cut seal stress, maintain air distribution, and reduce interface pressure during patient transfer.

A radial plastic spring layout prevents arm overlap in molding while creating a stable, symmetrical mattress support surface with better spring behavior.

Foam-filled air cells with zoned volumes and check valves spread body pressure without external inflation, helping prevent decubitus ulcers.

Connected outer spring arms return inward to prevent overlap during compression, improving demolding ease and lateral stability.

Discrete gel or foam columns in surrounding support material buckle under load to spread pressure, absorb shocks, and reduce hotspots.

Zoned fluid channels, spacer material, and thermal conditioning help a bed topper manage pressure, heat, and moisture to reduce ulcer risk.

Large through-holes let the foam creep laterally under compression, improving anatomical support without complex mattress contouring.

Independent nodal air groups and a thermal plenum prevent tenting and over-depression while improving patient temperature control.

Outer spring-supported plate sections deflect independently to improve mattress support resolution while cutting material and support cost.

By offsetting spring arms from the lower support surface, this plastic spring element increases travel while maintaining stable seat support.

Independent inflatable cells tilt the mattress laterally to maintain pressure redistribution, reduce bedsores, and limit caregiver handling.

Secure rail brackets, adjustable members, and spring-pin transfer bars help fit different bed frames while reducing entrapment risk.

Interrupted incisions in a latex or foam comfort layer open into air passages when stretched, improving ventilation, moisture removal, and softness.
