Frictional Force Resistors TRIZ Cases
- Elliptical Trainer Pedal Linkage for Natural Gait Motion
A backward-tilted pedal linkage creates a closed path that mimics walking motion, reduces foot strain, and supports full-body training.
- Stationary Bike Linkage for Synchronized Slope and Resistance
A cable-linked lifting arm adjusts bike slope and magnetic flywheel resistance together, widening incline range and making riding feel more realistic.
- Bidirectional Cable Resistance Using Adaptive Magnetic Load
Adaptive magnetic resistance replaces weight stacks to deliver bidirectional cable loading, compact size, and safe mid-motion stopping.
- Disc Brake Pad Linkage for Smooth Strength Machine Braking
Pivoting brake pad arms and a spring-rocker linkage create full disc contact to reduce stick-slip, noise, wear, and startup effort.
- Free-Steering Training Sled With Omni-Wheels for Uneven Terrain
Omni-wheels and a 6°-15° tilted frame let a resistance training sled turn smoothly on uneven ground without lifting or unstable towing.
- Dual-Trolley Burpee Machine for Larger Users and Adjustable Resistance
Two sliding trolleys on a horizontal frame give larger users adjustable resistance for modified burpees that target abs and core.
