Gearing TRIZ Cases
- CVT Variator Axial Position Control at High RPM
Limiting variator axial position changes to a maximum shaft speed reduces belt tension and shock loads during ratio adjustments.
- Belt Buckle Linear Drive Spindle Column Guide
A belt buckle presenter spindle integrates a coaxial support column to eliminate bending moments and reduce noise emissions during axial displacement.
- Rear Wheel Steering Housing Segmentation for Axial Load Management
Segmented housing design with integrated stopper portion manages axial loads in rear wheel steering systems.
- Belt Drive Wheel Hub Reduces Unsprung Mass
Replacing metal gears with a composite belt drive reduces unsprung mass and improves driving dynamics.
- Vehicle Seat Slide Assembly with Manual Release Mechanism
A vehicle seat slide assembly uses a lead screw and drive nut system to enable manual sliding of the seat.
- Oil Wet Toothed Belt Vibration Damping Guide
Fixed guide walls dampen toothed belt vibrations, reducing flapping and extending component life without complex tensioning devices.
- Integrated Ball Screw Slide with Hollow Shaft Motor Drive
Integrating a hollow shaft with an electric motor eliminates separate clutch components, reducing device complexity while maintaining high axial force handling.
- Adjustable Idler Wheel Track Roller Assembly
Adjustable idler keys in the track roller assembly resolve wear-induced engagement issues by enabling simple height changes without removable spacers.
- Internal-Circulation Ball Screw Reducing Thread Crest Impact
Redirecting channels link helix and returning paths to eliminate interrupted threads, preventing ball impact on thin thread crests.
- Drive Belt Tensioning Device with Cam Mechanism
A drive belt tensioning device uses a cam adjustment portion to maintain consistent force on the transmission belt.
- Cam Mechanism for Rotary to Reciprocating Motion Conversion
Replacing slider-crank links with a cam-follower system eliminates high specific pressure at piston pins, preventing lubricant leakage.
- CVT Pulley Misalignment Reduction via Dynamic Shaft Positioning
Dynamic shaft positioning via hydraulic actuators reduces belt misalignment, frictional stress concentration, and power loss in CVTs.
- Magnetic Ball Iron Powder Collection in Rack-Driven Steering
A magnetic ball collects iron powder between rack bar and ball nut screw grooves, reducing frictional force and noise during high-speed vehicle travel.
- Irrigation Track Assembly Pivot Steering
Hinge plate and locking pin pivot the drive wheel hub to follow curved paths, eliminating buckling and off-set loading stress on the irrigation system.
- Variable Speed Alternator With Adjustable Pulley Diameter
An adjustable pulley assembly varies the driven speed of a variable speed alternator, resolving inefficiency from fixed pulleys at normal operating ranges.
- Wedge-Damped Blade Tensioner Chain Vibration Control
Tapered distal end wedges with a mating block channel to dampen chain vibrations through friction and normal forces.
- L-Shaped Bushing Plain Bearing for Wind Turbine Gearbox Deformation
Adaptive L-shaped bushings accommodate planet gear deformation under high dynamic loads, reducing wear in multi-megawatt wind turbine gearboxes.
- Automotive Transmission Lever Mode Switching Mechanism
A vertically movable gear shift lever switches between joystick and rotary operation modes via an integrated driving unit.
- Tire Inflation Cam Pump with Eccentric Mass Stabilization
A tire inflation pump uses a cam and eccentric mass to translate rotation into linear pumping motion.
- Automatic Transmission Control Logic for Torsion Elimination
Segmented control logic prevents erroneous running status determination caused by output shaft rotation during torsion elimination.
- Vehicle Height Adjustment System Assembly Simplification
A vehicle height adjustment system connects an input piston part to a lead screw via direct fastening components.
