Stuffed Mattresses TRIZ Cases

Segmented seams in a multi-layer impermeable spring fabric adjust airflow under load, improving quietness, welding consistency, and feel.

A five-layer polyurethane foam hardness gradient cuts wobble and seat weight while preserving comfort and steering stability.

A harder center and softer side foams improve thoracic pressure distribution, reducing upper back fatigue and discomfort in seating.

A groove-like facilitating part lets the seat pad bulge bend independently of the hard back layer, improving occupant sink and hip point position.

Perimeter strings with rectangular spring convolutions replace foam encasement, preserving edge support through rolling, shipping, and unrolling.

A rigid yet foldable foam foundation uses crosswise supports and vacuum sealing to cut shipping volume without losing mattress support.

A separate non-quilted mattress panel replaces stitched quilting to create a smooth surface, reduce waste, and improve manufacturing reliability.

Different upper and lower pocket layers let a spring unit combine comfort, protection, and zone-specific support without separate product variants.

Independent hollow profiles with adjustable air chambers make mattress cores recyclable while enabling zoned firmness, bed independence, and adaptable support.

Conditioned air is routed through spacer-layer channels in a mattress pad to create localized heating or cooling for personal sleep comfort.

Independently deflatable air cells create a bedpan recess without moving the patient or removing the bedspread, reducing caregiver effort.

Offset coil ends and lacing-wire engagement improve innerspring stability, reduce wire use, and avoid high-tensile forming wear.

Rotating lateral and footboard extensions enlarge the sleeping surface without replacing the bed frame, while also forming a fall barrier.

Microencapsulated PCM printed near the mattress surface absorbs body heat while the high-loft non-woven layer preserves breathability.

Side-access removable inserts let users tune mattress support by location and firmness without pumps, complex parts, or added maintenance.

Fans, ducts, and thermoelectric air channels regulate mattress zones and reclaim heat to maintain a user-selected sleep surface temperature.

A barrier covering on the ventilation member blocks resin infiltration, preserving foam expansion, bonding, and seat comfort.

A separate pad compartment above each pocketed coil spring improves pressure distribution, preserves resilience, and avoids added mattress padding layers.

Flexible washable sensors embedded in textiles detect liquid without losing softness, while an interface element forwards data for real-time alerts.

Detachable spacer textile inserts let a bulky comfort mattress be washed in standard machines while preserving pressure relief and airflow.

Sensors track temperature and humidity changes, letting a controller run the pump only when needed to keep mattress firmness consistent.

Pressure sensing and stored comfort settings let inflatable mattresses reach preferred firmness quickly without recalling arbitrary levels.

Air channels and porous side rails let mattress cores shed heat and moisture without sacrificing edge support or load-bearing comfort.

Dynamic deflate profiles and corrected pressure feedback help air mattresses reach user-set pressure faster and more accurately.

Pressure-sensed inflatable comfort and support zones adjust automatically to body changes during sleep for more personalized alignment and comfort.

Surface-bonded internal strips replace heavy bands and manual rope links, improving air mattress flatness, support, and production automation.

Interlinked polymer fibers replace foam to tune mattress motion transfer, vibration damping, and load-deflection behavior with better recyclability.

An integral mattress extension enlarges the upper sleeping area without a step deck, preserving support, stability, and roll-off protection.

Selective bladder inflation combines patient support, transient therapy forces, pressure redistribution, and vapor transmission in one mattress.

Angle sensors and pressure feedback regulate zoned air bladders in real time to improve pressure relief across patient sizes and bed positions.

Independent interlocking blocks use cushioning, magnets, or hook-and-loop fastening to create reconfigurable furniture, wall, and floor surfaces.

Snoring-triggered inflatable bladders gently shift sleeping position to reduce snoring without waking or restricting the sleeper.

Airflow channels, inflatable supports, and pressure sensors help reduce pressure sores while enabling bed-exit alarms and patient weighing.

Lengthwise zones with different mechanical characteristics create four flat resting profiles, improving comfort while easing mattress transport and storage.

Dual flexible mesh suspension layers on pivoting carriers replace heavy box springs while improving airflow, temperature control, and support.

Canvas-foam-canvas encasement layers reinforce coil spring mattress borders, keeping edges straight and reducing sleeper roll-off over time.

Pivoting spring sections, a transition section, and biasing straps let a sofa mattress fold compactly into low-profile furniture without losing comfort.

A mechanical pressure-sensing linkage opens and closes an inflatable object's valve automatically, avoiding fragile electronics and manual pump control.

A telescoping holder slides between the mattress and box spring to store bedding and pillows off the floor, then retracts out of sight.

Cut and bent sheet springs in a stacked, staggered array improve mattress support under moving loads while simplifying manufacture.

Longitudinal cuts in welded spring tubes let each spring compress independently, giving mattresses uniform softness in any load direction.

Pump housing pressure sensing lets an air bed reach the selected chamber pressure faster and more accurately without stopping the pump.

A midsection strap loop and embedded harness close side gaps, prevent rolling, and support safer one-handed diaper changes.

Nested fluid pods and pads redistribute sacral and trochanter pressure without bottoming out, enabling portable ulcer prevention on standard surfaces.

Parallel lever arms, cam biasing, and hard stops let a bed side rail move smoothly between raised and stowed positions while staying secure.

Wrapped spring wire supports let foundations and innerspring mattresses vary firmness by changing support density and placement.

Segmented airflow channels and thermoelectric conditioning deliver faster, more even bed-surface heating or cooling for occupant comfort.

A zip-fastened mattress and duvet envelope keeps bedding together, packs into one unit, and avoids air-mattress leaks in caravans and boats.

Airflow through a vapor-permeable multi-layer support surface lowers interface pressure and removes heat and moisture to help prevent bedsores.

A detachable seat back uses common channel connections to swap lap, three-point, or child restraint options without changing the seat base.
