Stuffed Mattresses TRIZ Cases

A hinged two-pad mat with an abdominal cutout relieves belly pressure, supports stomach sleeping, and folds for easy transport.

Angled holes in a tubular foam spring tune softness and support while keeping manufacturing practical through pre-cut slits.

An overhanging mattress enlarges the upper sleeping surface beyond the base footprint while still supporting users without extra bed support.

Interchangeable foam springs let users tune mattress firmness by body zone, improving back support and pressure-point comfort.

Interchangeable modules and a rotatable cabinet turn one furniture unit into storage, a desk workstation, or a bed with simple reconfiguration.

Removable foam support members fill mattress impressions and add support without opening the mattress or voiding its warranty.

A segmented leg frame supports sofa bed conversion without a sliding seat, preserving wall placement, stability, and a cleaner structure.

A one-piece seat cushion composite uses insert materials with different compression properties to create comfort zones at lower cost.

Selective support material inside flow-connected cushion cells prevents bottoming out while preserving adjustable pressure relief and seated stability.

Foam blocks with internal cavities and a latticed stud mat spread body pressure, reduce peak points, and improve ventilation.

Alternating identical unknotted coil springs with high-tensile wire keeps spring cores aligned, reduces leaning, and cuts wire usage.

A convex tri-layer foam core resists heat- and moisture-driven sagging, improving pressure distribution, heel protection, and patient access.

Offset terminal ends and a gradient arm improve lacing-wire interconnection, reduce coil leaning, and maintain mattress comfort.

Densified edge support and irregular plastic-wire elasticity help users exit the bed safely while maintaining mattress airflow.

A calibration standard cell and selector valves let a multi-cell mattress zero pressure sensors and equalize cell pressure without opening each cell to air.

A one-piece plastic ring spring with an integrated receiving section simplifies mattress assembly while improving positioning flexibility and load distribution.

Variable-speed substrate feeding forms adjustable flutes without roller changeover, enabling stronger, water-resistant corrugated products.

Independent foam barrels can be repositioned by body area to tune mattress firmness and improve support for back pain, arthritis, and changing comfort needs.

A concealed rod, rack, and latch mechanism keeps the mattress aligned on an adjustable bed during articulation without visible retainers.

Open-cell polyurethane side rails let air and moisture move through the mattress edge, improving cooling without losing edge support.

Alternating single and nested springs with partially divided seams improve initial softness, individual coil action, and surface resilience.

An integrated preloading band inside the spring element limits deflection while preserving flexible, direction-independent support and easy installation.

A single-piece drawstring secures chair upholstery to raised portions so coverage and tension stay aligned as the back reclines.

A tuned polyurethane gel layer with controlled hardness and hysteresis spreads body pressure evenly while preserving stable comfort in foam-backed mattresses.

Segmented inflatable bladders with flexible joints and series airflow help adjustable mattresses maintain firmness during bed articulation.

A child-operated bed cover controller combines light, sound, parent contact, and airflow ports to ease bedtime fear under the covers.

Stitched foam compartments and a deformation-resistant fabric cover let an open-cell mattress topper be washed without breakdown.

Interchangeable filling parts let one chair support cushion vary thickness and stiffness for patient positioning, comfort, and safer lifting.

A layered breathable pad separates liquid drainage from waterproof protection to improve comfort, hygiene, and mattress reprocessing.

Interlinked polymer fiber structures replace foam in spring cores to tune motion transfer, vibration damping, load curves, and recyclability.

A sealed trim module lets ventilated seat covers detach without damaging cover stock, while preserving airflow, support, and lower seat weight.

A shaft-wound flexible bunk frees truck sleeper cab space by rolling away when unused while still providing a stable bed or shelf.

A PTFE membrane vent lets sealed infection-control bedding breathe while blocking liquid and microbial ingress and resisting pressure.

Series exhaust reservoirs and valves regulate fluid-cell pressure in a closed cushioning system, preventing contamination and bottoming out.

Cutting the concertina pattern after sealing thermoplastic sheets removes pre-folding, lowering cost and speeding expandable structure production.

Longitudinal spring-strand chambers stabilize support across body positions and improve spring interaction with slatted frames.

A dual-layer fitted sheet uses sealed edges and a Velcro-like attachment to keep a mattress securely covered and resist dislodging.

Straps routed through support-base openings secure the crib mattress to the frame, preventing accidental lift and suffocation risk.

UV-activated color change and a translucent rip-stop cover reveal tears and hidden contraband in institutional mattresses.

Removable core and topper cartridges tailor zonal firmness to body measurements, sleep habits, and weight distribution for better spinal alignment.

Independent gel or elastomer columns buckle under load to equalize pressure, relieve shear, and improve body alignment.

Joining pocketed coil springs only at the bottom cuts shear stress, preserves independent vertical deflection, and simplifies mattress assembly.

Forced airflow through a vapor-permeable, liquid-blocking coverlet removes heat and moisture while easing pressure on bedbound patients.

A layered bedding assembly combines moisture sensing, wicking, absorption, and waterproofing while remaining machine washable for incontinence care.

A gravity-actuated angle valve adjusts alternating pressure pad inflation without mattress electronics, improving safety, cleaning, and pressure relief.

Non-planar foam layers and fan-driven air passages regulate heat and humidity in body supports while preserving conformability and comfort.

Individually pressurized air cells and force sensors rebalance body load to reduce peak interface pressure and tissue stress on chairs or beds.

Color-changing translucent covering and microporous vents expose mattress tampering and contraband while blocking fluid passage.
