Vehicle Door Mirror Turn Lamp with Integrated Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps with multiple light sources and electronic components are bulky and complex, requiring multiple mounting plates and increasing the number of components, making them difficult to mount and manufacture.
Innovation Solution
A vehicle lamp design that integrates a lens portion and base housing with a light source portion, where first and second light sources are mounted on a substrate with terminal plates that are bent to differentiate their irradiation directions, allowing for compactness and reduced component count, and includes a power terminal on the substrate to eliminate the need for lead wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light source units with different irradiation directions are mounted on separate substrates, then the light sources can irradiate in different directions, but the light source units increase in size and the number of components increases
Solution Approach 1:
Multiple light source units with different irradiation directions are integrated onto a single substrate instead of using separate substrates. The substrate includes multiple terminal plates that are bent at different angles to provide different irradiation directions, thereby reducing the number of components while maintaining the capability to irradiate in different directions.
Solution Approach 2:
A single substrate serves multiple functions by incorporating multiple light source units with different irradiation directions. The terminal plates on the substrate are bent at various angles to achieve different light emission directions, allowing one substrate to replace multiple separate substrates and perform multiple irradiation functions simultaneously.
2Adaptability or versatility
If multiple light source units are mounted on separate substrates, then the light sources can be directed toward respective directions, but the mounting work becomes troublesome and complicated
Solution Approach 1:
Multiple light source units are combined onto a single substrate, which simplifies the mounting process. Instead of mounting multiple separate substrates, the integrated substrate can be mounted as one unit, thereby reducing mounting complexity and troubleshooting while maintaining the capability to direct light in multiple directions through bent terminal plates.
3Reliability
If light source units are firmly mounted via mounting plates in a standing condition, then the mounting is secure, but the structure becomes further complicated
Solution Approach 1:
Multiple light source units are integrated onto a single substrate, which reduces the overall structure complexity. The integrated substrate can be mounted more simply compared to multiple separate mounting operations, while still providing secure mounting through the unified structure.

AI summary
A vehicle lamp includes a lens portion; and a base housing incorporated with a light source portion, the base housing integrated with the lens portion in a butting condition. The light source portion includes first and second light sources, a substrate, a first light source terminal plate and a second light source terminal plate implanted in the substrate so as to create a gap from each other, and an electric or electronic component that turns on the first and second light sources. A front-end part of at least one of the light source terminal plates is bent toward the other light source terminal plate so as to differentiate the first and second light sources in an irradiating direction.
