Stretcher TRIZ Cases
- Contoured Bed Pad with Removable Cover for Patient Repositioning
Segmentation separates the support structure from the hygiene layer, resolving trade-offs between patient comfort and device complexity.
- Autonomous Stretcher With Transverse Transfer Litters
Motorized stretchers with transverse litters automate patient transfers, eliminating manual handling risks and nurse intervention.
- Dynamic Auxiliary Wheel Load Control for Hospital Bed Stability
Dynamic auxiliary wheel deployment resolves the contradiction between straight-line grip and cornering stability by retracting wheels during maneuvers.
- Retractable Stop Coupling for Patient Transport Equipment
Resilient biasing locks the coupling during high acceleration while an actuator enables quick release, resolving attachment security versus operational speed.
- Cable-Driven Foot Section Actuation for Patient Beds
Replacing bulky linear actuators with a compact cable-pulley system frees support frame space while easing manual foot section adjustment.
- Patient Transport Litter Trolley Pin Docking Mechanism
Pin stops on a sliding trolley dock a patient litter to a base frame, eliminating transfers between stair chairs and cots.
- Patient Transport Frame Assembly With Integrated Device Mounting
A patient transport frame assembly with a handle and brace surface supports treatment devices during stair navigation.
- Patient Lifter with Shifting Fulcrum for Variable Mechanical Advantage
Dynamic fulcrum adjustment increases initial lifting force while reducing device weight, resolving portability constraints in manual patient lifters.
