Portable Lifting TRIZ Cases
- Hand-Guided Load Device with Sensor-Controlled Cable Verticality
A hand-guided lifting device uses sensors and actuators to maintain cable verticality during load movement.
- Monobloc Pulley Sheave Spacer Friction Reduction
A monobloc pulley sheave uses a spacer element to space the fixing rope away from longitudinal faces.
- Tower Crane Pulley Block End-Position Detection
Load sensor analysis identifies the physical end-of-travel position to replace manual estimation and reduce safety margins.
- Tiltable Test Stand for Chain Hoist Stability and Attachment
A tiltable test frame reorients from vertical to horizontal to simplify heavy hoist attachment.
- Point Contact Gear Conjugate Curves Load Capacity
A point contact gear pair uses conjugate curves to mesh convex and concave tooth surfaces in one or more points.
- Non-metal Sprocket with Embedded Textile Reinforcement for High Torque
Embedded textile reinforcement in a castable polymer sprocket body resolves durability issues by increasing hardness and wear resistance under high torque.
- Helical Limited Slip Differential Surface Profile
Raised portions and indentations on helical LSD pinion gear top lands minimize noise and vibration by reducing friction.
- Integral Spring Split Gear Backlash Reduction
Integrating the spring with the second gear wheel eliminates assembly complexity and tolerance stack-ups while absorbing opposing torques.
- Forged Bevel Gears with Controlled Curvature
Controlled relative radius of curvature sections in forged bevel gears reduce sensitivity to centering distance variations.
- Chain Block Rolling Restriction for Dragging Stability
Rolling restriction portions on chain block frames prevent gear case damage and dust ingress during dragging operations.
