Dynamo-Electric Machines TRIZ Cases
- Linear Vibration Motor Damping via Intermediary Clamped Damper
Clamped dampers absorb vibrational energy from elastic members to stabilize linear vibration motor output.
- Linear Vibration Motor Groove Baffle Magnet Retention
Recessed grooves and baffles in the magnetic frame mechanically retain permanent magnets, preventing detachment during drop tests.
- Linear Actuator Downsizing via Axial Electromagnetic Resonance
An electric linear actuator eliminates mechanical conversion mechanisms by aligning a magnet and coil along the winding axis, reducing device volume.
- Flat Linear Vibrator Parallel Motion Height Reduction
Parallel vibration with base blocks limits amplitude, reducing height while protecting elastic members.
- Retaining Plate Sensor Mounting for Rotary Electric Machine
A retaining plate clamps an angular position sensor against a bearing, resolving bulky adjustment systems while ensuring vibration resistance.
- Shaftless Scanner Mirror Drive Using Voice Coil Actuation
A scanner mirror drive uses a voice coil to generate torque directly on the pivotable mirror assembly.
- Slanted-Pole Actuator for Dual-Axis Optical Scanning
Merging magnets into one slanted unit reduces device volume while maintaining driving force.
- Linear Vibration Motor Compact Stator Embedding
Embedding stator ends into housing holes reduces internal space, solving the trade-off between fixing reliability and housing size.
- Linear Vibrator Pole Plate Recess Shock Absorption
A linear vibrator weight includes a pole plate recess and magnetic fluid damper to absorb shocks during drops.
- Actuator Shaft Bending Points for Mirror Rotation Angle
Bending points in the torsion shaft extend effective length to increase mirror rotation angle without enlarging the optical scanner.
- Induction Generator With Oscillating Coil and Spring Element
An induction generator moves a coil within a stationary magnetic field using a spring element to induce oscillation.
