Electric Winding TRIZ Cases
- Multi-Stage Frequency Conversion Circuit for Radio Wave Timepiece
A multi-stage frequency conversion circuit processes received signals using a frequency divider to generate local oscillating frequencies.
- Watch Crown Tilt Control via Proximity Sensor
Tilting a watch crown generates proximity sensor signals for digital control while maintaining case sealing integrity.
- Wristwatch Piezoelectric Oscillator Frequency Customization
A wristwatch clock generator uses a piezoelectric crystal and pulse counter to produce precise timing signals.
- Optical Position Detection Light Restriction for Watch Precision
A light transmission restriction unit constrains passing light diameter to compensate for manufacturing tolerances and backlash errors in wristwatch detection.
