Nursing Beds TRIZ Cases
- Medical Bed Connectors for Lowered Lying Surface Position
Rearranged connectors place connection points below upper frame levels, lowering the bed surface to reduce fall injury risks.
- Mattress Pneumatic Control for Bed Frame Section Movement
Independent mattress pneumatic control prevents overrun and billowing by adjusting bladder volume during bed frame extension or retraction.
- Bathing Apparatus Seat Lift with Variable Torque Torsion Spring
A seat lift for bathing uses a torsion spring to bias a hinged back while guiding reversible vertical and lateral movement.
- Retractable Sheet Strips Preventing Floor Contamination
Webbing pulls loops into the pocket to eliminate floor contact and trip hazards.
- Stair Lift Arm Rest L-Shaped Pivot Clearance
Asymmetric L-shaped arm rest extends beyond the seat plane to create 135 mm clearance for users navigating tight stairwells.
- Tiltable Ceiling Lift Motor Unit Pivot Mechanism
Pivoting motor units align with patient sling tension to eliminate side loading and shear stress on patients.
- Ergonomic Patient Transport Device with Reinforced Handholds
A portable lifting aid uses a durable rectangular main body and multiple straps to form secure handholds for assistants.
- Inflatable Mattress Gyroscope Pressure Control
Embedded gyroscope detects backrest inclination changes to adjust cell pressure, eliminating bed structure dependency and preventing bedsores.
- Rotatable Air Distribution Dial for Patient Support Systems
A rotatable air distribution dial controls communication between an air supply source and multiple patient support air cells.
- Bed Transforming Mechanism with Adjustable Seat Height
Guide members on slats engage tracks to lower the foot end, adjusting seat height for users of varying leg lengths without auxiliary equipment.
- Dual Connecting Rod Bed Base for Wall Collision Avoidance
Segmented rods reduce sliding displacement, preventing wall collisions during patient tilting.
