Nursing Beds TRIZ Cases
- Configurable Siderail with Lateral Movement and Radial Slot Guide
A siderail assembly moves laterally between deployed positions using a radial slot guide mechanism.
- RF Position Detection for Automatic Vital Sign Sensor Association
RF transceivers detect relative device positions to automatically associate vital sign sensors, eliminating manual cable connection steps.
- Height Adjustable Bed Leg Assembly Spring Biasing
Compressed springs release stored energy to counteract gravity during initial lift, reducing motor power requirements for height adjustable patient supports.
- Heel Protection Mattress with Dual Compressor Pressure Relief
Inflatable mattress uses dual compressors to manage cyclic cell deflation for patient support.
- Medical Pad Wetness Detection via Electrical Resistance
An integrated electric circuit and sensor measure electrical resistance to transmit wetness data wirelessly, eliminating manual checks that disturb patients.
- Self-limiting Electrosurgical Return Electrode with Pressure Sore Reduction
A self-limiting electrosurgical return electrode integrates heating elements and pressure sore pads to maintain patient comfort during procedures.
- Hospital Bed Foot Section with Telescopic Panels for Egress
Telescopic foot panels retract upon floor contact to clear the egress path, resolving the trade-off between support surface area and patient mobility.
- Overhead Lift Unit Lateral Wheel Adjustment for Rail Mounting
Lateral wheel adjustment simplifies mounting overhead lift units onto rails without ladders.
- Automated Bed Side Rail Control via Motion Detection
A bed system uses a detector and controller to automatically adjust side rails based on user presence.
- Counter-Rotating Belt Table Assembly for Patient Transfer
Separate driving and delivery side plates prevent linen entrapment while maintaining stability during transport.
- Motorized Patient Transfer Board with Rotating Disk
A motorized transfer board uses a rotating disk to move patients between surfaces.
- Motorized Seat Lifting Mechanism for Fallen Elderly
A motorized seat assembly ascends within a frame via a threaded rod to lift users.
- Patient Lifting Apparatus with Cable Pulley System
A patient lifting apparatus uses a cable pulley system and winch mechanism to raise a support platform.
