Nursing Beds TRIZ Cases
- Spring-Loaded Sling Bar Latch for One-Handed Attachment
A spring-loaded retention latch secures sling loops within a receiving aperture, enabling one-handed operation to resolve the two-hand manipulation bottleneck.
- Rail-Mounted Lift Location Tracking via Transmitter Receiver Pairing
A rail-mounted lift system uses paired transmitters and receivers to track carriage position along the support channel.
- Motion Sensor Pressure Ulcer Risk Detection System
An automated motion sensor system replaces subjective manual assessment with continuous movement analysis, providing objective pressure ulcer risk indicators.
- Patient-Controlled Hoist Drive Mechanism for Muscle Engagement
Signal receivers allow patients to control hoist drives, resolving the contradiction between provider operation and patient muscle tension timing.
- Mattress Topper Liquid Transport Layer and Air Mover
A mattress topper assembly uses a liquid transport layer and an air mover to manage moisture.
- Antimicrobial Rail Cover with L-Shaped Nesting Lips
Segmentation and composite materials enable antimicrobial rail covers that reduce microbe transmission without replacing existing structures.
- Electric-Movable Bed Platform with Segmented Plates for Bedsore Prevention
A segmented electric-movable bed platform uses rotatable plates and locking mechanisms to adjust patient positioning.
- Patient Support Apparatus Weight Logging via Force Sensors
A patient support apparatus uses force sensors to measure downward forces on the support deck for accurate weight readings.
- Articulating Patient Support Platform for Reclining to Sitting Transition
An articulating patient support platform pivots panels to move a patient from reclining to sitting.
- Mattress Bladder Control for Patient Bed Egress
A controller adjusts inflatable mattress bladders to maintain cushioning during patient bed egress movements.
- Adjustable Knee Pad and Secure Hook Mechanism for Patient Lift
A patient lift apparatus featuring adjustable knee pads and secure boom hooks for efficient handling.
- Multi-directional Adjustable Chair Bed with Electric Telescopic Rods
Electric telescopic rods coordinate sliding and upwarping motions of a segmented bed plate group to provide stand-up assistance for physically impaired users.
- Electro-mechanical Linkage for Mobile Lifter Base Stability
An electro-mechanical linkage automatically expands base legs during vertical movement, eliminating manual force required to stabilize the device.
- Telescopic Rail Guide Synchronization Mechanism for Nursing Beds
Rack and pinion gears synchronize telescopic rail guide movement, preventing unintentional extraction while maintaining a homely design aesthetic.
- Electric Bed Lumbar Support Assembly with Planar Four-Bar Linkage
A lumbar support assembly uses a planar four-bar linkage to move a support member vertically within a bed board through-hole.
- Patient Support Side Rail Timing Link Mechanism
A patient support side rail uses a timing link and latch mechanism to enable smooth rotational movement.
- Motion Controller Segmentation for Patient Support Actuator Control
Segmenting the control system into independent modules reduces communication latency and accelerates actuator response rates.
