Vehicle Tail Light Alignment via Cross-Assembly Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting structures lack an efficient mechanism to illuminate passive light elements within lamp assemblies using active lighting elements from separate assemblies, particularly in movable tail light configurations, leading to suboptimal light distribution and potential light leakage.
Innovation Solution
A vehicle lighting structure comprising a first lamp assembly with a light dispersing member and a second lamp assembly, where the second lamp assembly's lighting device emits light through aligned light passages to illuminate the light dispersing member within the first lamp assembly, ensuring efficient light distribution and minimizing leakage by using aligned light passages and a controller to manage the lighting device's operation based on the movable panel's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate second lamp assembly is used to illuminate the light dispersing member in the first lamp assembly, then light distribution efficiency is improved, but device complexity increases
Solution Approach 1:
The lighting system is divided into two separate lamp assemblies: the first lamp assembly containing the light dispersing member, and the second lamp assembly containing the lighting device. This segmentation allows independent optimization of each assembly's function while achieving efficient light distribution through their coordinated operation.
Solution Approach 2:
A controller is introduced as an intermediary component to manage the operation of the lighting device in the second lamp assembly. The controller receives signals about the movable panel's position and automatically controls the lighting device accordingly, eliminating the need for complex mechanical linkages or manual intervention.
2Object-generated harmful factors
If aligned light passages are used to direct light from the second lamp assembly to the first, then light leakage is minimized, but manufacturing precision requirements increase
Solution Approach 1:
The light passages in both lamp assemblies are pre-configured with aligned orientations during manufacturing. This preliminary alignment ensures that when the movable panel is in the closed position, the light passages automatically align without requiring complex real-time adjustment mechanisms, reducing both light leakage and the complexity of control systems.
Solution Approach 2:
The patent replaces complex mechanical alignment mechanisms with a simpler system where the light passages are fixed in predetermined orientations. The alignment is achieved through the rigid structural relationship between the lamp assemblies and the movable panel, eliminating the need for adjustable mechanical components.
3Illumination intensity
If the lighting device operates continuously to illuminate the light dispersing member, then illumination intensity is improved, but energy consumption increases
Solution Approach 1:
The lighting system transitions from a static, continuously operating design to a dynamic system that adjusts operation based on real-time conditions. The lighting device in the second lamp assembly is controlled to operate only when the movable panel is in the closed position, creating a dynamic on/off pattern that reduces energy consumption while maintaining illumination intensity when needed.
Solution Approach 2:
The lighting device operates periodically rather than continuously, activating only during specific conditions (when the movable panel is closed) and remaining inactive during others. This periodic operation pattern maintains sufficient illumination intensity during active periods while significantly reducing overall energy consumption compared to continuous operation.

AI summary
A first lamp assembly has a first side surface with a first light passage and a hollow interior with a first light dispersing member disposed therein. The first light dispersing member is positioned to receive light emitted through the first light passage and emit light received via the first light passage. The second lamp assembly has a hollow interior with a first lighting device disposed therein, and a second side surface with a second light passage. The first lighting device is positioned to emit light through the second light passage, such that when the second light passage and the first light passage are adjacent to one another with the first and second light passages being aligned, and with the first lighting device operating, the first lighting device emits light through the second light passage into the second light passage illuminating the first light dispersing member within the first lamp assembly.
