Machines/Engines TRIZ Cases

Balancing shaft diameter, central free space, and blade overlap helps Savonius turbines preserve recirculation while reducing friction and exceeding 30% efficiency.

Parallel thermoelastic elements share a carriage to deliver rotary motion while shortening the actuator footprint and preserving actuating force.

A simple immersed vibrator measures damping time to track liquid level continuously without reducing container capacity.

Flexible trailing-edge elements passively deform under gust loads, then recover their shape to reduce blade stress and fatigue.

A high-voltage DC supply drives parallel electrode pairs to deflect ionized exhaust, avoiding gimbals and vanes for lighter, more reliable rocket steering.

Divided contact surfaces spread hydraulic and impact forces, reducing fuel-injector sticking and contact stress for repeatable motion.

An annular permanent-magnet stack and coaxial electrodes create ECR plasma in one ionization and acceleration zone without complex grids.

A two-part wind turbine rotor blade limits a swirl element’s outer span to under 25%, easing transport and delaying flow separation.

To meet RF limits, the control unit splits a frequency sweep into paused partial intervals, lowering average transmission power while preserving measurement precision.

Relative engine motion from shifting weight or wind can disturb probe alignment; sensors and computer-controlled actuators maintain stable inspection or repair.

Separating shaping and anchoring elastics into layers distributes contact forces while maintaining fit, stability, and skin comfort.

Chord-aligned endplates increase lift by nearly 9.1% and reduce drag by over 30% on vertical-axis wind turbine airfoils.

Using the balancer shaft to drive an auxiliary machine separates its placement from the crankshaft, improving space flexibility.

The thruster collects atmospheric gas, then ionises and accelerates it electromagnetically to reduce onboard storage mass and volume in LEO.

Guide members align the injector during cylinder-head assembly, reducing distortion while direct accumulator connection limits pressure loss.

A junction box links multiple wind-turbine converters to fewer tower cables, reducing wiring complexity, weight, and on-site installation work.

An inclined exhaust port on the air cleaner cylinder reduces visible opening area, limiting dust entry into the clean intake conduit during maintenance.

A rigid-flexible forward bulkhead combines thermoplastic composite support with woven fabric layers to absorb bird-strike energy and protect nacelle skins.

A starter pre-rotates the compressor before clutch engagement, reducing standby fuel use and clutch wear in blasthole drill rigs.

Separate mounting relationships increase cost and assembly difficulty; rotor integration places the engine oil control valve inside the regulator.

A controller lowers engine speed when calculated headroom is sufficient, reducing fuel use and wear while preserving traction output during load changes.
