Converting Sensor Output TRIZ Cases
- Magnetic Rotary Control Assembly for Compact Electronic Products
Separating the rotary controller from the electronic body uses magnetic position detection to keep precise input while reducing product size and easing storage.
- Resolver Housing Structure for Magnetic Crosstalk Shielding
Segmented magnetic and amagnetic housing parts shield resolver windings from transformer fields, improving angular measurement accuracy.
- Magnetic Sensor Bobbin Layout for Shared PCB Component Space
Downward bobbin supports lift the coil above the PCB, creating space for nearby components without sacrificing Barkhausen sensor function.
- Complex Baseband Resolver Demodulation for Precise Rotor Position
High-speed sampling and complex baseband demodulation correct resolver noise, delay, and gain errors for more accurate rotor position.
- Configurable Sensor Housing for Multi-Orientation PCB Connectors
A single sensor housing with selectable side openings lets PCB connectors be positioned to match customer orientation needs while cutting tooling cost.
- ESD Protection Circuitry for BCI-Resistant Position Sensor Signals
Segmented ESD diodes protect signal inputs and ground reference to suppress BCI noise and preserve accurate inductive position sensing.
- Encoderless BLDC Motor Position Sensing from Sinusoidal Voltage Signals
Sinusoidal voltage sensing and matrix transformation replace encoder hardware to improve BLDC motor position accuracy without filtering.
- Encoder Light-Receiving Module with Fiber Optic Plate for Accurate Detection
A fiber optic plate brings the input surface closer to the light passage pattern, reducing diffusion while protecting the light-receiving element.
