Interior Lamp Integrated into Vehicle Glass Roof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior lamps for vehicles, especially those with glass roofs, face the challenge of requiring additional space and being positioned suboptimally due to their separate installation, leading to less effective illumination of the vehicle interior.
Innovation Solution
The interior lamp is integrated directly into the glass roof, using a housing with a ring-shaped printed-circuit board and light-emitting diodes, with supply and control leads integrated into the laminated glass, allowing the lamp to be seamlessly embedded without obstructing the glass roof's functionality, and featuring a transparent output element for uniform light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the interior lamp is arranged separately from the glass roof, then the lamp can be installed independently, but it occupies additional space and requires a less suitable location resulting in less optimal illumination
Solution Approach 1:
The patent merges the interior lamp with the glass roof by integrating the light source directly into the glass roof structure. The light source is positioned in the glass roof such that its light output is directed into the vehicle interior, combining the functions of the glass roof and interior lighting into a single integrated component, thereby eliminating the need for separate lamp installations and additional space.
2Area of stationary object
If the interior lamp is integrated into the glass roof, then space is saved and illumination is optimized, but the glass roof structure becomes more complex
Solution Approach 1:
The patent segments the glass roof structure into multiple layers or zones to accommodate the light source integration. The glass roof is designed with specific regions that house the light-emitting components while maintaining the overall transparency and structural integrity of the glass roof, allowing complex functionality to be achieved through structured segmentation rather than monolithic design.
Solution Approach 2:
The patent introduces intermediary components such as light guides, diffusers, or reflective surfaces within the glass roof structure to manage light distribution. These intermediary elements facilitate the integration of the light source into the glass roof while maintaining optical performance and structural simplicity, acting as mediators between the light source and the vehicle interior.
3Area of stationary object
If the interior lamp is integrated into the glass roof, then the glass surface remains largely usable, but the frame separating the lens from the glass pane becomes visible when the lamp is off
Solution Approach 1:
The patent employs optical elements with varying transparency or color properties that change their appearance based on lighting conditions. The frame or separating structures are designed to be visually blended with the glass roof when the lamp is off, using color matching, transparency gradients, or reflective properties that make the frame imperceptible under normal lighting conditions, thereby eliminating visual distraction.
Solution Approach 2:
The patent uses optical elements that replicate or mimic the appearance of the surrounding glass roof. The frame or separating structures are designed to optically copy or blend with the glass surface, making them indistinguishable from the surrounding transparent areas when the lamp is not in operation, thus maintaining the aesthetic and functional integrity of the glass roof.
