Interengaging Clutches TRIZ Cases
- Dog Clutch Ratcheting One-Way Assembly for Faster Shifting
Ratcheting rockers and springs hold torque in one direction, align clutch teeth, and shorten shift time without extra synchronization.
- Damped Claw Coupling for Fast, Low-Noise Interlocking
A spring-loaded shift ring and damping chamber slow tooth-to-tooth engagement, cutting stress and noise while keeping fast coupling.
- Quick Disconnect Coupler for Junior Dragster Drivetrain Separation
A movable coupler and release button disconnect the engine from rear wheels quickly, avoiding manual belt removal on Junior Dragsters.
- Shaft Spring Clutch for Fastener Driving Without Handle Rotation
A spring-return clutch lets the bit spin freely until axial force engages torque transfer, improving comfort and reducing fastener ejection.
- Sliding Driveline Coupling for Easier Maintenance and Lower Wear
A laterally movable coupling disconnects shafts for easier inspection and service while maintaining torque transfer and reducing wear.
- Hybrid Drum and Gear Assembly for Lightweight Torque Transfer
An aluminum drum intermeshes with a steel gear assembly to cut transmission weight and cost while preserving rigidity and wear resistance.
- Centrifugal Clutch Mass Assembly for Precise Radial Engagement
Radially offset apertures and a guidance plate enable precise centrifugal mass movement for reliable clutch engagement without added parts.
- Railway Welding Machine Coupling Structure for Wear-Resistant Replacement
A modular male-female coupling with shaft keyway and teeth reduces wear and simplifies replacement in railway welding machine drives.
- Axle Disconnect Sleeve Assembly for Torque-Blocked Mode Transitions
A resilient shift lever stores elastic energy to keep an axle disconnect operating through torque and misalignment blocked modes.
- Power Switching Gear Mechanism for Shared Scan and Feed Drive
A movable active gear shares one motor between scanning travel and paper feeding, cutting cost while keeping both mechanisms operating reliably.
- Door Drive Clutch-Spindle Mechanism for Manual and Motor Operation
A clutch-driven spindle lets a furniture or appliance door switch between motorized torque transmission and easy manual movement with fewer parts.
- Internal-Gear One-Way Clutch for Compact High-Torque Transmission
A top-land to bottom-land gear contact lets an internal-gear one-way clutch shrink in diameter without losing transmission torque or adding axial size.
- Mechanical Anti-Backlash Shaft Coupling With Manual Reconnection
A preloaded leaf spring and bellcrank coupling removes cable actuation, prevents backlash, and simplifies reconnection on solid shafts.
- Door Drive Coupling Mechanism for Manual and Motorized Operation
A rotation-actuated clutch shifts axially to couple or decouple a threaded spindle, enabling one-motor door movement and easy manual operation.
- Toy Gearbox Axial Cam Clutch Shifting Without Stickshift
Rotating an axial cam moves a slidable driving ring to engage toy gearbox gears, avoiding complex stickshift parts and improving layout versatility.
- Generator Disconnect Coupling Timing to Reduce Wear Debris
Rotational-position-based disconnect timing separates the generator input member within a target angle range to cut wear, debris, and maintenance.
- Positive-Drive Clutch Using Rotational Displacement Engagement
Relative rotational movement drives a cam and stop arm to shift the clutch plate into positive engagement without separate actuation.
