Lighting Circuits TRIZ Cases

Relocating the light source to the instrument panel expands door trim coverage and creates patterns that change with door opening angle.

A vehicle lighting controller captures user color preference and adjusts in-cabin light sources to personalize ambient color without fixed factory settings.

Warning content is shown in the driver's current line of sight, helping explain door-side road hazards and the needed response during hop-off.

Dynamic vehicle exit alarms extend when multiple occupants try to get out near obstructions, improving attention calling without repeated alerts.

A door-mounted EV charging port lamp widens downward lighting, reduces glare, and simplifies lamp replacement and maintenance.

Specific gesture sequences control vehicle interior lighting while filtering parasitic movements that could distract the driver.

Gaze-tracked cabin light zones brighten only in the driver’s line of sight, easing eye strain while cutting manual switching, energy use, and LED wear.

Touch-panel finger motions steer interior light direction, intensity, and color without ceiling switches, reducing reach effort and mis-irradiation.

A PCB shaped to match interior vehicle components replaces fragile light guides, cutting routing complexity, space use, and cost.

Current-direction sensing lets linear network nodes self-identify addresses and positions with fewer pins, lower setup time, and noise-resistant signaling.

Short 1-50 ms light pulses with idle gaps raise alertness in dim workspaces while limiting energy use and visual disruption.

Gradually increasing vehicle interior light near a tunnel exit helps adapt the driver's eyes and reduce temporary blindness risk.

Sensors detect passenger state and trigger seat-specific light, airflow, temperature, and tint changes to personalize cabin comfort.

Independently opened trim cells direct conditioned air and light to changing passenger positions for more precise in-cabin comfort.

A rotatable masking cover lets one garnish area display multiple illuminated vehicle symbols, improving program selection without hurting aesthetics.

A faceted translucent body with reflective regions redirects and refracts light to create distinctive interior vehicle illumination.

A silicone optical path translator couples interior vehicle lights to the window, limiting cabin light leakage while preserving exterior visibility.

Exterior and interior cues plus sensors guide riders to reserved seats and block wrong-seat occupancy in autonomous ridehail vehicles.

Analog partial-current control uses LED bin-class signals to equalize vehicle lamp brightness while minimizing resistor heat loss.

Photoluminescent socket markings help passengers find power and media ports in dim aircraft cabins without added power use or bright glare.

A deformable lens lets one light source redirect and refocus cabin lighting, reducing roof space and module count while lowering cost.

Real-time sensor and vehicle data are converted into light-module video sequences, replacing fixed patterns with adaptive in-cabin visualization.

Vehicle decorative light guides carry high-speed optical signals to replace bulky wiring harnesses while preserving appearance and placement flexibility.

Graphical zone profiles and per-zone color controls simplify vehicle ambient lighting setup and improve feedback on color assignments.

Sensor-driven vehicle spotlights light only the needed zone based on occupant presence, location, and task to reduce shadows and disturbance.

A telescopic steering column with position sensing stores and recalls driver settings while removing extra motors and switch assemblies.

Sensors detect unsafe activity around a vehicle and trigger projected visual alerts plus device control to protect users inside and nearby.

Passenger feedback adjusts dirt-detection thresholds so autonomous vehicle interiors can be cleaned between rides with fewer service visits.

An inflatable tube and handle unit help vehicle occupants float to the surface in flooding accidents while keeping the rescue hardware compact.

Independently addressable LED segments and a light guide plate enable vehicle interior lighting to adapt in real time to sensing, occupancy, and preferences.

A dual-optical housing combines cabin illumination and exterior information projection to cut hardware cost while keeping both light functions clear.

Removable sensor skin tracks occupant biometrics and automatically adjusts HVAC, audio, lighting, and suspension to reduce distraction.

A sealed wireless light board uses an integrated battery and transmitter link to simplify vehicle accessory installation and avoid battery replacement.

A rear personal lamp switches between high and low illuminance to provide safety lighting and cabin ambience without adding extra lamps.

Distributed microcontrollers at each cabin LED cut wiring and PCB space while enabling individually addressable color and animation control.

Integrated steering wheel controls let drivers dim an airbag cover emblem at night, reducing distraction without losing logo visibility.

A controller links seat movement to consoles, displays, and vents so separate cabin components reposition together with less user effort.

Sequential control of in-vehicle light units guides occupant gaze toward detected objects and improves alerting in bright or poor-visibility conditions.

Distributed steering wheel lighting guides hand placement and vehicle state recognition, helping drivers respond faster during autonomous driving.

Position-based control activates light glasses only outside the vehicle in low daylight, reducing fatigue without impairing road safety.

Programmable red and amber lamp circuits let one vehicle lamp handle tail, turn, and brake functions while reducing lamp count.

A trim insert under a translucent cover integrates light, display, or sensor modules while avoiding foam-caused distortion and preserving soft touch.

Closely spaced perforations and individually addressable LEDs create a low-profile leather-covered vehicle display with durable adhesion and natural grain.

Local PVB openings let diodes be integrated into a laminated vehicle sunroof with fewer bubbles, delamination defects, and scrap.
