Nursing Beds TRIZ Cases
- Bathtub Lift Dual-Rack Gear Drive Stability
Segmented rack and pinion mechanism distributes uneven loads to prevent tilting in extended positions.
- Lift Chair Web Assembly for Patient Transfer
An extendible web assembly acquires patients without pre-positioning, reducing localized pressure stresses on skin.
- Self-locking Clamp Mechanism for Patient Helper Position Stability
