Power Operated Starters TRIZ Cases
- Engine Start Control Around Centrifugal Clutch-In Speed
Feedback control boosts engine speed for quick starting, then holds it at or below clutch-in speed to avoid unwanted clutch engagement.
- Centrifugal Clutch Engine Start Control for Stable Quick Starting
Feedback control of throttle and fuel keeps engine speed at or below clutch-in speed, enabling quicker and safer starting with less user effort.
- Spring Box Cover Locking Structure for Compact Turning Gear
Integrated cover-to-base locking removes screws and bosses, shrinking spring box space while simplifying turning gear assembly.
- Flywheel Housing Blow-By Gas Path Without Longer Crankcase
A side-positioned blow-by gas path in the flywheel housing improves gas discharge and simplifies pipe routing without enlarging the engine.
- Aircraft Navigation Data Blending for Low-Uncertainty Flight Control
Blending GPS, inertial, and sensor data with Kalman filtering and statistical weighting improves aircraft navigation accuracy and uncertainty control.
- Starter Pinion Toothing Profiles to Prevent Engagement Jamming
Different internal and external toothing profiles prevent burr contact during starter engagement, avoiding jamming and rework costs.
- Automatic Flywheel Starting With Speed-Responsive Drag Torque
A speed-responsive drag torque starter gradually accelerates a high-inertia flywheel, easing engine start-up without complex dual-mass structures.
- Starter Torque Limiter Friction Disc for Compact High Torque
A larger-diameter friction disc boosts starter torque capacity in a compact limiter while keeping torque transmission stable and protecting the motor.
- Belt Starter-Generator Torque Ramping for Smooth Engine Restart
A two-stage starter-generator torque profile pre-tensions the belt before cranking, cutting restart noise, belt stress, and delay.
- Integrated Starter Clutch and Balancer Gear for Compact Engines
By combining the one-way clutch and balancer drive gear, this engine layout cuts crankshaft axial length and weight while preserving starter function.
- Starter Drive Pinion Bevel Geometry to Prevent Gear Jamming
Graduated bevels on starter pinion tooth flanks prevent simultaneous tooth contact, reducing jamming, wear, and rough ring gear engagement.
- Engine Drive Reduction with Free Wheel for Smooth Phase Transitions
A one-way free wheel lets the electric machine start the engine, then disengages on combustion torque to prevent pulley and motor damage.
- Blower Housing Starter Assembly for Heat-Isolated Engine Cranking
A blower-housing-mounted starter and battery use worm gear and clutch soft start to keep engine cranking components away from heat and vibration.
- Dual Mass Flywheel Coupling for Automatic Start-Phase Locking
A resilient coupling member locks dual mass flywheel masses during engine start using pinion-driven deformation, avoiding active control.
