Castors TRIZ Cases
- Flanged Roller Elastic Hook Fixation
Elastic hooks on the intermediate flange clip onto the hub perforation, preventing detachment during impacts while maintaining assembly simplicity.
- Caster Wheel Bumper Impact Absorption
Protective bumper absorbs impacts and distributes forces around caster wheel assembly, preventing damage to supported objects and surrounding surfaces.
- Caster Wheel Stabilizer Mitigates Flutter in Zero-Turn Mowers
An elastomeric stabilizer sleeve mitigates caster flutter by generating counteracting torque, preserving bearing life and steering ease.
- Wheel Connecting Device Shaft Stabilization
A wheel connecting device uses a sleeve member and retaining member to stabilize the shaft within the mounting seat.
- Dual Configuration Portable Wheelchair with 6-Bar Linkage
A collapsible wheelchair uses a 6-bar linkage to switch between front and rear steering configurations.
- Spherical Wheel Caps with Secant Pivot Axes
Secant pivot axes allow rigid motor shafts without equatorial gaps, eliminating support discontinuity and slippage.
- Hospital Bed Wheel Fixing Arrangement Without Welding
Segmented components replace welding to reduce manufacturing costs while maintaining connection strength.
- Truckle Assembly Limiting Unit for Simultaneous Motion Control
A truckle assembly limiting unit integrates a pedal and gear ring to arrest wheel movement.
- Forklift Side-Shift Attachment with Sensor-Limited Travel
A forklift side-shift attachment uses sensors to measure lateral travel distance and control the adjustment mechanism.
- Hub-Mounted Motor Wheel for Compact Heavy Load Transport
Integrating a motor and reduction gear within the wheel hub reduces lateral extension while lowering the center of gravity for heavy load transport.
- Furniture Roller Pin Collar for Impact Damage and Bearing Play
A castor fastening pin features a central collar-like material thickening that acts as a support bearing.
