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.

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.
