Vehicle Head Lamp Dynamic Image Expression via Movable Lamp Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle head lamps have a static structure that lacks the ability to express dynamic images or shapes, failing to meet the growing demand for personalized and aesthetic lighting solutions.
Innovation Solution
A head lamp system comprising a first and second lamp module, where the second lamp module can be moved to overlap or not overlap with the first lamp module, allowing for various images and shapes to be expressed by controlling their positions and activation states, utilizing a plurality of lamps and actuator mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static head lamp structure is used, then the manufacturing complexity is reduced, but the ability to express dynamic images and shapes is lost
Solution Approach 1:
The patent applies the dynamics principle by making the second lamp module movable relative to the first lamp module. The second lamp module can be positioned in different locations (first location overlapping with the first lamp module, second location not overlapping) to create different visual effects. This dynamic positioning capability allows the head lamp to express various dynamic images and shapes, transforming a static structure into a dynamic one that can adapt to different lighting scenarios.
Solution Approach 2:
The patent divides the head lamp into multiple independent lamp modules (first lamp module and second lamp module) that can be controlled separately. The second lamp module can be independently positioned and controlled to overlap or not overlap with the first lamp module, enabling the creation of different patterns and images. This segmentation allows each module to perform specific functions and contributes to the overall dynamic image expression capability.
2Adaptability or versatility
If multiple lamp modules are added to create dynamic images, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the second lamp module to serve multiple purposes: it can be positioned at a first location to overlap with the first lamp module creating one type of lighting pattern, or positioned at a second location to not overlap creating another pattern. This single component performs multiple lighting functions, increasing adaptability without proportionally increasing the number of components. The controller also manages multiple functions by coordinating the on/off states and positions of different lamp modules.
3Adaptability or versatility
If the second lamp module is moved to create different patterns, then the design satisfaction is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-defining specific positioning locations for the second lamp module (first location and second location) rather than allowing continuous movement. These predetermined positions are designed to achieve the desired overlapping and non-overlapping effects with the first lamp module. By limiting the movement to discrete pre-determined positions, the manufacturing precision requirements are reduced compared to requiring precise continuous positioning, while still achieving the image expression capability.
