Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamps using organic electroluminescence (EL) panels require complex assembly processes for connecting the panel and power feeding sections, increasing assembly time and costs.
Innovation Solution
A vehicle lamp design that integrates the organic EL panel's first electrode with the power feeding section's second electrode during fixing, eliminating the need for separate connection work by using a resistor and a bracket system to ensure constant brightness and secure the panel, allowing for simultaneous electrical connection and fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connector or feeder cable is used to connect organic EL panel and power feeding section, then electrical connection is achieved, but assembly man-hours increase and cost increases
Solution Approach 1:
The patent merges the electrical connection function with the mechanical fixing function by integrating the electrode directly into the mounting section. The first electrode of the organic EL panel is formed integrally with the mounting section, eliminating the need for separate connectors or feeder cables. This single-integration approach achieves both electrical connection and mechanical fixation simultaneously, reducing assembly steps and man-hours while maintaining reliable electrical connection.
2Reliability
If connector or feeder cable is used to connect organic EL panel and power feeding section, then electrical connection is achieved, but cost increases
Solution Approach 1:
The patent combines the electrode and mounting section into a single integrated structure. By forming the first electrode integrally with the mounting section, the invention eliminates the need for separate connector components and feeder cables, thereby reducing part count, material costs, and assembly costs while ensuring reliable electrical connection between the organic EL panel and power feeding section.
3Productivity
If organic EL panel is fixed to mounting section with integrated electrode, then connection work is omitted, but structural complexity increases
Solution Approach 1:
The mounting section is designed with multi-functionality, serving both as the mechanical support structure and as the electrical connection element. The first electrode is formed integrally with the mounting section, allowing the same component to perform dual functions: fixing the organic EL panel mechanically and providing electrical connection. This multi-functional design simplifies the overall system by reducing the number of separate components needed.
4Object-affected harmful factors
If bracket system is used to hold organic EL panel, then panel protection is achieved, but device complexity increases
Solution Approach 1:
The patent integrates the protective bracket function into the existing mounting section structure. The mounting section, which already serves as the mechanical support and electrical connection element, is designed to also provide protection for the organic EL panel. By combining multiple functions (support, electrical connection, and protection) into a single integrated structure, the invention achieves panel protection without significantly increasing device complexity.
