Electric Power Supply Circuits TRIZ Cases
- Rotary Energy Harvester With Offset Gearing for Low-Power Electronics
Offset and speed-increasing transmissions raise generator RPM from manual rotation, enabling compact battery-free power for remotes, watches, and sensors.
- Rechargeable Smartwatch Strap for Waterproof Universal Charging
A strap-integrated charging coil and control circuit enable universal watch charging without a dedicated charger or compromising waterproof sealing.
- Transparent Solar Cell Cavities for Clarity and Power Generation
Blind cavities and a refractive-index-matched protective layer improve see-through solar cell clarity without sacrificing power generation.
- Wearable Power Interface Switching to Minimize Rusting
Intermittent power switching during motion-triggered detection windows reduces rusting at a wearable band-to-housing power interface.
- Ambient-Brightness Mode Switching for Lower-Power Electronics
Different bright and dark switching conditions cut unnecessary power use by adapting electronic mode changes to ambient light and user behavior.
- Wearable Band Power Interface Timing to Reduce Rusting
Motion-triggered intermittent power windows cut rusting at the wearable band-housing interface while preserving attachment detection.
- Rotary Crown Smartwatch Interface for Analog Navigation
Rotary crown motion detection selects symbols to resolve smartwatch interface complexity for elderly users.
- Solar Cell Laser Shaping With Protective Film Barrier
A protective film with at least 1 μm thickness acts as a thermal barrier to prevent molten material damage during laser shaping of solar cell substrates.
- Solar Cell Wiring via Stress-Distributing Conductive Paste
Fine particle conductive paste averages applied stress to prevent power generating film damage and improve electrostatic resistance.
- RTC Battery Charging Control for Cycle Life Extension
A control unit manages RTC battery charging via user-set date and time settings to prevent unnecessary power cycles.
- Timepiece Temperature Compensation Circuit
A timepiece uses an evaluation circuit to compare register data before accessing nonvolatile memory for temperature compensation.
- Solar Panel Positioning for GPS Antenna Performance
Positioning a solar panel in the thickness direction between a dial and module maintains antenna characteristics without reducing the light receiving area.
- Watch Circuit Initialization for Autonomous Peripheral Control
Initialization means configure autonomous peripheral controllers, reducing electrical consumption from 7.6 μA to 400 nA and extending battery life.
