Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamps require custom-designed boards for each shape, leading to increased manufacturing costs and limited adaptability to various designs, especially in small-lot large-kind production.
Innovation Solution
A vehicle lamp design featuring a board with multiple mounting portions in both longitudinal and lateral directions, allowing for flexible LED placement and a detachable reflector member that can be adapted to different arrangements, enabling the same board to accommodate various lamp shapes and designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a custom board is designed for each lamp shape, then the lamp can conform to specific design requirements, but the manufacturing cost increases and adaptability to various designs decreases
Solution Approach 1:
The board is designed with multiple mounting portions arranged in different directions (longitudinal and lateral) that can accommodate LED light sources in various arrangements. A single board type can be used across different lamp models by selectively mounting LEDs and attaching different reflector members, eliminating the need to design custom boards for each lamp shape while maintaining design versatility and reducing manufacturing costs.
Solution Approach 2:
The lamp assembly is divided into independent modular components: a standardized board with multiple mounting options, detachable reflector members with specific shapes, and LED light sources. This segmentation allows each component to be optimized independently and recombined in various configurations to create different lamp shapes without requiring custom boards for each design.
2Adaptability or versatility
If multiple mounting portions are arranged in both longitudinal and lateral directions, then adaptability to various LED arrangements is improved, but device complexity increases
Solution Approach 1:
The board incorporates multiple mounting portions arranged in both longitudinal and lateral directions, allowing the same board structure to support various LED arrangements (single LED, multiple LEDs in different patterns). This universal board design achieves high adaptability without requiring complex specialized structures for each LED configuration.
Solution Approach 2:
The board features mounting portions with different local characteristics (positions, orientations) in longitudinal and lateral directions, allowing selective use of specific mounting portions based on the desired LED arrangement. This enables flexible LED placement while maintaining a relatively simple overall board structure.

AI summary
A single board is adaptable to lamps for a vehicle of various designs. A lamp for a vehicle includes: an LED light source; a board having a mounting portion on which the LED light source is mounted; and a reflector member which is arranged such that the reflector member covers the LED light source, the reflector member reflecting light emitted from the LED light source with the directivity, wherein the mounting portion is formed of a plurality of mounting portions which are arranged at least in one direction out of the vehicle longitudinal direction and the vehicle lateral direction such that the arrangement of the LED light source is selectable from plural kinds of arrangements, and the reflector member is detachably attached to the board such that the reflector member having a shape corresponding to the arrangement of the LED is selectable.
