Nursing Beds TRIZ Cases

A configurable ceiling lift uses dual or single motor modes to handle varying patient weights.

Feedback control adjusts fluid supply based on plenum pressure to maintain optimal fluidization levels despite varying user weights.

A motorized conveyor belt assists lateral transfer of mobility devices into vehicle seats.

Asynchronous motor control adjusts person support width without synchronized coordination, reducing mechanical complexity and easing manual operation.

Fluid-filled actuators in a dynamic support apparatus adapt to user movement, reducing pressure concentrations that cause sores.

Integral ribs on a davit column define channels for tool mounting, reducing weight while maintaining structural rigidity.

Linear actuators pivot bed sections to reposition patients, reducing caregiver strain and bedsore risks.

Separate electric motors drive winding spools while one-way bearings force guide rollers into rotation, preventing strap jamming during unwinding.

Eccentric pivots in a patient moving device enable smooth reorientation of the support platform, reducing caregiver strain and improving transfer reliability.

Telescopic support frame assembly replaces complex screw locks with friction-based gravity retention to resolve stability versus setup time contradictions.

Two rollers wind a low-friction sheet into dual layers that slide against each other, resolving high friction during manual patient repositioning.

Segmented cart sections and a hydraulic actuator lift users from seated positions, reducing device complexity while maintaining operational stability.

Coupling mechanism merges wheeled accessory with patient support apparatus into single unit, eliminating need for second caregiver during transport.

Antenna transfers configuration data to communication circuitry while the patient support apparatus remains in packaging, eliminating manual setup labor.

Pull rod transmission connects bed head and tail gearboxes to resolve heavy, noisy mechanical trade-offs in rehabilitation beds.

A patient positioning wedge integrates pressure sensors to detect weight distribution and transmit usage data wirelessly.

Dynamic chamber inflation redistributes contact pressure to prevent localized ischemia and mitigate pressure injury formation.

A lift control system determines accumulated load-time parameters to trigger maintenance alerts based on actual usage intensity.

Embedded controllers convert messages between Ethernet, CAN, and RS-485 protocols over a shared bus.

Motorized positioning of segmented bed parts enables independent elimination while eliminating caregiver back strain from manual handling.

Integrating rails into longitudinal beams eliminates separate attachments, reducing manufacturing complexity and assembly steps.

Floor-standing columns replace suspension structures to eliminate maintenance hazards while rigid gas tubes ensure durable supply.

A portable support structure with vertically spaced handholds enables users to safely transition between standing and floor positions.

Segmented housing with a vertical rotational joint enables frame rotation without twisting straps or entangling electrical cords.

A patient care device communication system segments internal networks by protocol to enable secure external integration and efficient data transport.
