Lighting Circuits TRIZ Cases
- Vehicle Interior Lighting Bus Control for Fewer Wires
A host ECU sends one effect instruction over LIN or CAN to multiple lamp units, cutting wire harness size and communication load.
- Vehicle Interior Lighting LIN Fail-Safe Without Response Delay
A host ECU sends normal and fail-safe LIN commands so lamp units keep responsive lighting control without bidirectional state reporting.
- Automotive Ambient Lighting with Touch Sensing and Haptic Feedback
Sharp-contrast light guides, capacitive touch sensing, and vibration actuators turn cabin ambient lighting into an interactive automotive interface.
- Gesture-Activated Vehicle Light Bar for Driver Visibility Without Glare
A gesture-triggered interior light bar illuminates the driver's upper body so pedestrians can read signals clearly without windshield glare.
- Vehicle Interior Light Modules for Real-Time Ambient Lighting Control
Runtime-variable sensor and vehicle data drive distributed interior light modules to deliver adaptive light scenes, effects, and warning signals.
- Vehicle Interior Control Profiles for Personalized Cabin Settings
User-selected profiles coordinate display, sound, lighting, seat, temperature, and window settings to create a personalized vehicle cabin.
- Roof-Mounted Launch Control Activation for Driver Focus
A roof-mounted launch control button uses upward reach and peripheral visual cues to cut search time while keeping the driver focused on the road.
- Dynamic Stripe Projection Lamp for Variable Automotive Ambient Lighting
Individually controlled RGB LED units and matched lenses vary stripe color, length, and width to make automotive ambient lighting more diverse.
- Vehicle Cockpit Screen Interaction for Low-Latency Coordinated Control
Application-screen template matching replaces AI object detection to cut cockpit control latency, complexity, and interface cost.
- Driver Warning Output Based on Attentiveness and Gaze Direction
Expanded in-vehicle warnings use attentiveness and gaze sensing to improve registration without redundant or annoying alerts.
- Cabin Illumination Cues for Low Emission Zone EV Entry
Cabin LEDs change color or blink at low emission zone entry, helping drivers notice the switch to EV mode without relying on text alerts.
- Driver Warning Escalation for Autonomous Driving Handover
Multimodal HUD, sound, and steering-wheel vibration warnings restore driver attention and trigger handover when response is delayed.
- Vehicle Accent Lighting With Inductive Power to Prevent Fluid Ingress
Wireless inductive power removes cupholder wiring penetrations, preventing fluid ingress while simplifying vehicle accent lighting installation.
- Vehicle Illumination Control Using Front and Upper Brightness Sensing
Dual front and upper illumination sensing improves outside brightness estimation, helping vehicle lighting adapt in tunnels, parking lots, and other changing environments.
- Smart Key Biometric Preconditioning for Personalized Vehicle Entry
Biometric and GPS data from a wireless key let the vehicle precondition climate, lighting, and audio before entry, reducing manual adjustment.
- Vehicle Lamp Assembly Control via Factory Input Devices
Factory switches, buttons, or touchscreens are reused to configure aftermarket vehicle lamps, avoiding extra wiring and control hardware.
- Vehicle Linear Lighting Control for Dynamic Status Communication
Dynamic linear lighting patterns use vehicle status and sensor data to convey alerts and ambient cues without adding more indicators.
- Driver Attention Warning Escalation During Autonomous Driving
Escalating HUD, vibration, and sound warnings re-engage inattentive drivers and support safe transition from autonomous driving.
- Vehicle Cabin Control Flow Using Time-Segmented Mode Settings
Time-segmented mode settings let one vehicle cabin control flow drive multiple operation devices across modes with less development burden.
- Vehicle Cabin Illumination Control for Accident Biometric Imaging
During vehicle accidents, adaptive lamp color control improves biometric imaging of specific body sites when uniform cabin lighting fails.
- Vehicle Light Synchronization With External Light Shows
AI-based image processing matches vehicle lights to nearby home light shows while adjusting patterns for battery state, users, and ambient light.
