Door Lighting TRIZ Cases
- Integrated Vehicle Running Board Mounting to Prevent Sticking
An integral mounting bracket and auxiliary transmission mechanisms keep a vehicle running board stable and usable when the drive fails.
- Vehicle Door Molding With Selective LED Illumination
A light-blocking layer and embedded LEDs let vehicle door moldings illuminate selected regions for decorative, logo, and warning effects.
- Backlit Vehicle Door Panel Embossments With Soft Light-Guiding Structure
Soft, deformable light-guiding embossments create point-source door panel backlighting while reducing occupant injury risk on contact.
- Interior Component Assembly with Wrapped Edge Insertion Structure
A protruding wrapped edge inserted into a mating component prevents upholstery wrinkles, crushing, and surface distortion during interior assembly.
- Integrated Roof Step Stowage in a Vehicle Door Frame
A stowable support member built into the door frame gives stable roof access while avoiding door interference and vehicle damage.
- Vehicle Interior Trim With Hidden Thin-Film Display Integration
Glass-based trim integrates a hidden-until-lit thin-film display, sensors, and ambient lighting to avoid bulky, heat-prone interior lighting parts.
- Vehicle Badge Lighting with Embedded LEDs and Opaque Polymer
Side-emitting LEDs embedded in clear polymer material create a uniform edge-lit effect, resolving hot spot issues while maintaining waterproof durability.
- Removable Vehicle Control Panel Shield with Sensor-Driven Illumination
A removable protective cover shields vehicle control panels from water ingress while an illumination unit creates visible button outlines.
- Optical Grating Distortion-Free Vehicle Indicia Projection
An optical grating embedded in a light transmissive layer directs collimated light to project virtual images, resolving distortion on curved vehicle surfaces.
- Vehicle Door Sill Display with Dynamic Orientation Control
A vehicle door sill display uses a transparent element and controller to orient images for occupants.
- Photoluminescent Side Marker for Door-Off Visibility
A photoluminescent side marker charges from ambient light to emit sustained illumination toward the vehicle exterior.
- Vehicle Running Board Lighting with Optic End Caps
Hidden light sources emit toward optic end caps to resolve the contradiction between improved illumination intensity and deteriorated aesthetic appearance.
- Flat LED Light Device for Automotive Door Steps
Side-edge illumination diffuses light across a planar panel, reducing thickness and eliminating mounting cutouts.
