PROJECT TOPICHealthcare, Assistive & Bio-Mechatronics
Smart Patient Transfer Lift
An assistive hospital mechatronics concept exploring electric ball-screw lift columns, sling tension balance monitoring, and smooth acceleration curves to safely transfer non-ambulatory individuals.
Safe & Ergonomic Patient Repositioning
- ✓Continuously monitors sling weight distribution to detect patient slippage.
- ✓Applies smooth S-curve acceleration to eliminate sudden jarring motions.
- ✓Features motorized base leg widening to clear wide armchairs and wheelchairs.
The Engineering Challenge
Problem / Objective
Caregivers suffer frequent spinal injuries from manual patient lifting, while jerky conventional hoists cause anxiety and falls.
