Stretcher TRIZ Cases

A deformable brace with pins, slideways, and support surfaces lets one person align and secure a collapsible hospital bed faster with fewer loose parts.

A switchable linkage raises the thigh section with head elevation to limit patient migration and reduce caregiver strain.

Different ratchet bar slot profiles and a spring cylinder prevent pin wedging and simplify emergency cot height adjustment.

A retractable IV pole stored inside the litter handle prevents misplacement, reduces snagging, and enables quick bedside deployment.

Dual-friction sheet surfaces and angled wedges make patient turning easier, hold position consistently, and help reduce sacral pressure ulcers.

Synchronized display colors and reflected light help caregivers spot changing bed and patient conditions quickly, even from a distance.

A variable-volume sealed tank keeps air out and oil in, maintaining hydraulic pressure for accurate stretcher cylinder positioning.

A semi-rigid, quick-deploy screen uses rail tension mounting to provide patient privacy, practitioner access, and overhead light relief.

Color-matched indicators and reflected light help caregivers identify patient support status changes quickly from a distance.

A one-piece ABS bracket with offset wings and integral legs absorbs impact, distributes load, and helps prevent fractures in portable equipment support.

A squeeze-paddle swivel clip keeps backboard straps secure yet releases quickly even when blood or bodily fluids make removal difficult.

Offset load wheels and powered leg actuation balance bariatric cot loading, reducing manual support across ambulances and uneven terrain.

A gas spring drives a turbine generator to recharge stretcher batteries during deck movement, reducing reliance on mains power.

Independent or synchronized leg actuation helps heavy emergency cots load into ambulances and other rescue vehicles with less manual support.

A rotatable spring shifts a medical bed fifth wheel between extended and retracted positions without locks, reducing parts, damage risk, and retrofit space.

A reversible spring and swing arm raise or lower a medical bed fifth wheel without locks, reducing mechanism complexity, damage risk, and retrofit space.

Translating, articulating stretcher handles improve reach and leverage for users of different heights during transport, loading, and obstacle handling.

Adjustable main rods and modular lying elements let the stretcher pack compactly, assemble quickly, and move through narrow terrain.

A rail-guided arm with latch engagement and variable-speed drive supports cot transfer to cut EMS lifting strain during ambulance loading.

Modular attachment points and articulated trays let a stretcher carry medical equipment securely while preserving patient positioning and vital connections.

Articulating legs, lead screws, and edge detectors let one operator load heavy tools onto a truck bed while keeping the transporter level.

A detachable battery controller powers a belt-driven transfer board that moves a person from the ground with lighter weight and controlled handling.

A detachable roller and conveyor belt assembly lets medical transfer beds be cleaned and replaced quickly while keeping patient transfer stable.

A rail-mounted arm supports and positions the cot during ambulance loading, cutting lift strain, injury risk, and the need for a second attendant.

A rail-mounted arm supports and positions the cot during ambulance loading and unloading, cutting EMS lifting strain while securing engagement.

Overlapping plate sections and straps create a lightweight litter that deploys fast, supports dragging or lifting, and enables single-person evacuation.

A sliding carriage that switches from guide rail engagement to direct leg contact lets healthcare beds lower near the floor without bulky actuators.

Hydraulic flow redirection and tilt-capable lift links speed cot height adjustment for faster ambulance loading and unloading.

Shoulder and arm support platforms balance patient weight during upright transfer, improving stability despite caregiver-patient height differences.

A pivoting multi-panel foot barrier deploys from under the mattress to shield caregivers securely without loose sheets or slow setup.

A vertically movable, rotatable oxygen tank support clears patient access while preserving bed height adjustment and articulation.

A pivoting multi-panel foot barrier deploys above the mattress to shield caregivers and stay secure during patient transport.

A remote dashboard ranks bed status issues and highlights only the highest-priority condition to cut caregiver workload and alarm fatigue.

A compact trolley anchors biomedical devices to the patient bed, enabling one-caregiver transport with lower disconnection risk.

Gentle pulsing perimeter lights remind caregivers to complete bed configuration tasks before leaving, improving safety without disturbing patients.

Force-sensor exit zones shift with bed width, incline, and occupant position to cut false alarms and improve timely bed-exit alerts.

Magnetic damping and load-driven locking smooth pawl-ratchet engagement in an overhead support reel, reducing jolting and wear.

A movable spherical coupling head, powered legs, and locking guidance enable safer single-operator stretcher loading on slopes and ambulance surfaces.

A detachable battery controller powers a belt-drive board to move a person from the ground with lighter weight, alignment control, and safer transfer.

Pivot-coupled stretcher halves slide under patients for secure lifting, reduced spine displacement, and X-ray compatible transport.

Force and object sensing stop the lift when a stretcher base nears obstacles, preventing contact damage during vehicle loading and unloading.

Elevated multi-pull zippers and layered insulation improve patient access, transport, and heat retention in severe cold.

A center latch added to antler and rail restraints secures ambulance gurneys during crashes while preserving intuitive loading and fleet compatibility.

Movable upper pivots and hydraulic flow control extend cot tilt and lift range for quicker ambulance loading and unloading.

A movable shelf and connector assembly secures multiple medical devices, then retracts to improve patient transfer and bedside access.

An inverted Y-leg lift assembly lowers patient support to a very low height while preserving long travel, smoother force curves, and caregiver access.
