Stuffed Mattresses TRIZ Cases

Buckling first and second walls distribute weight more evenly, reducing pressure peaks and bottoming out in gelastic cushions.

Pivoting support arms let a bed assist handle raise for stable support and lower for caregiver access, sheet changes, and easier bed maintenance.

An attached top and bottom sofa sheet with elastic edges keeps cushions covered, prevents sheet slip during sleep, and fits varied sofa sizes.

Differential substrate speeds form adjustable flutes and enable bonding of low-plasticity materials into stronger, water-resistant corrugated products.

Open-cell foam inside an airtight air mattress uses check and regulating valves to balance support, suspension, and adjustable comfort.

A retainer belt pulls and secures the mattress during opening, giving a rolling cabinet bed safer deployment, stable support, and crease-free storage.

Fluid-filled bladders rolling along shaped posts redistribute body weight, reducing pressure points and the need for frequent repositioning.

Spaced strands between weldable plastic strips replace thick PVC bands, preserving inflatable shape while cutting weight and folded volume.

A microporous vent with a strengthening layer lets sealed bedding breathe while blocking liquid and microbial ingress under user pressure.

A dual-chamber air mattress delivers heated or cooled air around the patient while forming an air cushion underneath for easier lateral transfer.

Selective slit zones form built-in reinforcement ribs in a tubular foam spring, improving fatigue resistance and simplifying production.

Thin alternating visco-elastic and resilient foam layers improve body conformity and weight distribution without the sinking feel of thick memory foam.

Independent gelastic spokes buckle under load to lower tissue interface pressure, reduce ulcer risk, and cut cushion weight.

A slit-mounted air pouch lifts an inflatable bed backrest while allowing full deflation flush with the main body for comfort and compact storage.

Wave-shaped struts and connecting sections improve mattress spring tilt stability while keeping plastic molding simple and material use low.

Dynamic gain, filtering, and sensor activation improve hospital bed monitoring accuracy while limiting noise and unnecessary power use.

Integrated movement and vital-sign sensing predicts adverse patient conditions with condition scoring, caregiver alerts, and sleep-quality tracking.

A removable tether and locking dock keep a bedside control pendant secure, portable, and wirelessly charged to reduce loss and downtime.

Adjustable mattress and frame sections shorten intercorner distance in egress mode to shift the occupant's center of gravity closer to the heels.

Open-cell viscoelastic foam and a prestressed elastomeric coating evenize body pressure while improving airflow and reducing skin shear.

Pressurized air cushions create an air film that moves patients smoothly between surfaces while preserving applicator alignment for radiation treatment.

Semi-impermeable spring pockets slow air flow to mimic visco-elastic comfort while reducing heat retention and manufacturing cost.

Wheel well recesses, perimeter chambers, and support seams create a stable air mattress that fits vehicle beds and flat surfaces comfortably.

A foot-end alert light linked to bed control circuitry makes abnormal patient support conditions visible for faster caregiver response.

Integrally molded elastic connectors with directional crystalline alignment improve seating comfort while reducing creep and manufacturing cost.

Pressure sensors and adaptive bladder control reduce patient migration toward the bed foot end while improving comfort and easing caregiver repositioning.

A split spring structure keeps the upper layer soft while plate displacement adjusts lower-layer firmness for stable, independent support.

Low-friction shear transfer zones redirect mattress shear away from ulcer-prone skin while limiting patient sliding and cover bunching.

A fluid bladder beneath mattress padding carries heartbeat and breathing pressure waves to a sensor, improving comfort and detection accuracy.

Coiled spring arms around support plates reduce mattress friction, improve load distribution, and allow spring hardness tuning without changing rigidity.

Buckling gel springs redistribute pressure, absorb shock, and reduce vibration to relieve hot spots in cushions and mattresses.

Multiple-height buckling walls spread load evenly in a gelastic cushion to prevent pressure peaks, bottoming out, and hammocking.

Independent inflatable cells tilt the mattress laterally while regulating patient pressure to reduce bedsores without manual repositioning.

A convertible front wall lowers for bedside nursing, then springs or weights back up to reduce infant fall and suffocation risk.

Zoned fluid distribution and thermoelectric conditioning give the bed surface more uniform heating or cooling for individualized comfort.

Pressure feedback and microcontroller control let users quickly fine-tune inflatable bladder firmness without recalling preset levels.

Independent air-cell groups keep buttock pressure lower than back and thigh support, dispersing body load to help prevent decubitus ulcers.

Independently controlled inflatable bladders combine patient support, transient-force therapy, pressure redistribution, and vapor transmission.

A matrix of inflatable bladders with fluid channels improves patient immersion and pressure distribution, helping reduce pressure sore risk.

Angled slit cutting in a foam layer creates tubular foam springs with non-perpendicular holes, expanding shape options for pillows and mattresses.

Sequenced thermoelectric modules and continuous blower airflow deliver localized bed cooling or heating with lower energy use and faster comfort.

Flexible TPU sheets and internal connecting units replace heavy PVC to improve airtightness, flatness, comfort, and portability.

A movable plate and segmented elastic members vary lower-section clamping to tune mattress firmness while keeping the upper surface soft and stable.

A spacer-fabric mattress drains and contains liquids while shielding the base, improving comfort, hygiene, and frequent cleaning.

Different roller speeds form and anchor flutes in real time, expanding corrugation options while avoiding roller changeover downtime.

A channel-mounted spring bed frame turns a mattress into a jumpable surface while shielding exposed springs and preserving sleeping comfort.

Independent pressure control across grouped air cells reduces buttock repelling force while maintaining stable support and soft contact.

Rigid bearing parts spread load around a compressible core, cutting mattress weight and cost while improving damping and airflow.

Corrugated support and stabilizer wires let bedding spring assemblies nest for shipping while reducing sway without compression or tying.
