Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamp devices are limited in their range of functionality, requiring multiple types of lamps and complex constructions with fixed light sources, which increases weight and complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of lamps with fixed light sources are used to achieve different lighting modes, then the range of functionality is improved, but the device complexity and weight increase
Solution Approach 1:
The patent implements a single lamp device that can perform multiple lighting functions (headlamp, turn signal, fog lamp, brake light, tail light) by dynamically changing the light emission direction and distribution pattern through a movable light source and controllable beam shaping, eliminating the need for multiple separate fixed lamps
Solution Approach 2:
The light source is made movable rather than fixed, allowing it to change position and orientation to direct light in different directions. The beam distribution pattern is dynamically adjustable through movable reflectors and lenses, enabling the same physical component to serve multiple lighting modes
2Adaptability or versatility
If multiple types of lamps with fixed light sources are used to achieve different lighting modes, then the range of functionality is improved, but the weight increases
Solution Approach 1:
A single lamp housing contains a movable light source that can be positioned to perform multiple lighting functions, replacing multiple separate fixed lamps and thereby reducing the overall weight of the lighting system
Solution Approach 2:
Multiple lighting functions that would traditionally require separate physical lamps are merged into a single integrated lamp device with a movable light source and adjustable beam shaping components

AI summary
A lamp device for a vehicle includes a lamp housing and a light-emitting unit disposed therein. The light-emitting unit includes a light-emitting surface adjustable in at least one of a shape, an intensity of illumination, or a color of illumination. The lamp device further includes a bracket that supports the light-emitting unit to be mounted in the lamp housing, and that is configured to change the shape of the light-emitting surface of the light-emitting unit. The lamp device further includes a driving unit configured to apply a driving force to the bracket that changes the shape of the light-emitting surface of the light-emitting unit. The lamp device is configured to at least partially change, based on a plurality of lighting modes, at least one of the shape of the light-emitting surface, the intensity of illumination emitted from the light-emitting surface, or the color of illumination emitted from the light-emitting surface.
