Electrical Apparatus TRIZ Cases

Built-in sensors classify user activity and adjust headlamp beam shape and brightness automatically, removing manual lighting setup.

Cryptographic power authorization lets a lighting controller verify connected loads and detect unauthorized power draw from measured consumption.

Wireless mobile controls replace manual diffuser buttons and update a visual graph for atomization, timing, light, and music settings.

Recovered voltage from a primary LED load powers a secondary load, cutting heat loss while maintaining constant current after LED damage.

Off-state voltage sensing and complementary waveform estimation let a two-wire AC load control calculate real-time power without a neutral.

Integrated LEDs and a diffuser in an attachable handle create rear bias lighting that improves screen clarity in dark viewing without glare.

A current-mirror LED driver balances opposing temperature coefficients to raise drive current with heat and keep brightness stable.

A series light emitter and output-side photovoltaic section recycle voltage drop as photocurrent, boosting linear regulator efficiency with low EMI.

Wireless input lets external devices change lighting sequences, colors, intensity, and activation without physical access to the controller.

A synthesized fill-in signal creates a virtual AC waveform that keeps filter delay stable and prevents dimmer flicker under line noise.

A single digital message coordinates multiple LED drivers to dim fixture output while preserving a natural warm color temperature shift.

Cryptographic power-use checks let a lighting controller spot unauthorized loads on the power bus and protect safety and compliance.

Distributed operating appliances at each UV module cut cable cross section and power loss, enabling longer one-piece pipe liner curing.

A wireless remote measures light at the user’s location and adjusts fixtures directly, avoiding complex daylight sensor calibration.

Flight-state-based light direction and color cues help operators track distant drones at night while limiting unnecessary power use.

Induction preheating ahead of the welding arc balances the heat profile to raise welding speed while reducing distortion and post-weld stress.

Alternating the opening order of parallel MOSFET dimmers spreads switching energy, reducing size, losses, and light flicker.

PSK remote signaling and PWM dimming let AC mains LED luminaires switch and dim without ballasts, rewiring, or complex wired control.

A rotatable collar lets a disposal sensor and light target different areas while keeping the battery compartment easy to access.

A camera-guided pan-tilt lamp follows a surgeon's hand or instrument to keep the surgical site illuminated while reducing shadows, heat, and contamination.

GIS-based control maps crime, traffic, land use, and road classes to adjust street lighting brightness, color temperature, and distribution.

A voltage-dividing circuit and microprocessor let a NEMA street lamp node control light shape, color temperature, and brightness.

Separate pre-charge voltage and constant-current timing suppress switching noise and stabilize organic EL light emission in printing.

Frequency-coded light emitters and a receiver determine object position with higher accuracy and flexibility than satellite-based positioning.

Automatic discovery of connected lights, locations, and controls enables synchronized multi-location light displays with less setup effort.
