Safety/Regulatory Devices TRIZ Cases

Real-time sensing and alerts keep metalworking lubricant volume and concentration on target, reducing waste and protecting tool life.

A buoyancy-actuated ball vent seals the reservoir bore at full lubricant level, stopping refill overflow and avoiding external vent plumbing.

A float-actuated valve stem stops lubricant flow when the reservoir reaches full level, preventing overfill, contamination, and refill downtime.

Sensors and real-time alerts track lubricant volume and concentration to reduce waste, extend tool life, and keep part quality consistent.

A powder monopropellant feeder-combustor simplifies rocket propulsion, avoids cryogenic tanks, and enables continuous thrust control.

Different radial planes prevent piston interference, while alternating power and exhaust strokes support continuous pneumatic rotation.

This active-chamber engine uses stored compressed air to actuate a balanced intake valve, reducing expansion loss and controlling torque.

Segmented buoyant vessels and hydraulic accumulators manage flow surges while converting wave motion into zero-carbon hydrogen fuel.

Modular reciprocating cylinders and electric valves in a compressed air motor eliminate drivetrain components, reducing manufacturing complexity.

Radial branch retainers intercept ejected engine parts to prevent catastrophic fuselage damage while maintaining modular simplicity.

A hybrid dual-series lubrication system integrates parallel and progressive lines to maintain continuous flow through segmented paths.

Pivoting bars lift the hydroelectric module out of water, eliminating heavy machinery costs.

Hall sensor feedback controls separate intake and exhaust valves, optimizing compressed air flow to improve efficiency during partial load operation.

A liquid column generator uses a reciprocating piston to convert hydraulic pressure into mechanical energy.

Variable flow rate injector adjusts outlet diameter to maintain turbine efficiency across varying hydraulic conditions.
