Using Electrical Means TRIZ Cases
- Swivel Angle Measuring Device for Hydrostatic Piston Machine
A translational swivel angle measuring device uses a permanent magnet moved linearly by an adjustment piston to detect position.
- Wiegand Sensor Magnetic Shielding for Interference
High-permeability shielding elements redirect interference fields around a Wiegand sensor, resolving measurement errors in noisy motor environments.
- Position Sensor Pitch Deviation Determination via Zero-Crossing Analysis
A position sensor process determines total pitch deviation by recording angular signals and calculating pole pair lengths from zero-crossing positions.
- Capacitive Probe Layered Structure for Turbomachine Gap Measurement
A capacitive probe uses a layered structure with insulator buffers between metal and ceramic elements to enable unhindered thermal expansion.
- Generator Rotor Rotation Detection via Excitation Voltage
Evaluating excitation voltage swing instead of phase signals improves measurement precision and controller robustness against interference.
- Workpiece Support Device Reducing Deflection via Segmented Arms
Segmented first arms with contacting parts distribute weight around the center of gravity, reducing deflection for accurate roundness measurement.
- Displacement Sensor Gap Error Compensation Using Asymmetric Coils
A displacement sensor uses asymmetric receiver coils to generate differential signals for precise position tracking.
- Graphene Target Electromagnetic Sensor for Nanometer Position Measurement
An electromagnetic sensor uses a graphene layer target to reduce skin depth, resolving inaccuracies from eddy current penetration and environmental changes.
