Innovation Solution
A method for manufacturing a three-dimensional light emitting appliance involves creating a CAD data model of a car interior, arranging light emitting devices in a grid pattern, transforming this into a two-dimensional model, manufacturing a PCB, equipping it with LEDs, and shaping it to fit the three-dimensional form, allowing for even distribution and personalization of lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional functional lighting is used in car interiors, then the lighting serves basic illumination purposes, but the lighting lacks configurability, personalization, and dynamic ambient experience
Solution Approach 1:
The lighting system is segmented into multiple independently controllable light emitting devices arranged in a grid pattern on the three-dimensional surface. Each device can be controlled individually or in groups, enabling various lighting configurations, patterns, and effects without requiring a completely complex centralized control system.
Solution Approach 2:
The lighting system is designed to perform multiple functions: functional illumination, ambient lighting, dynamic patterns, and personalized configurations. The same hardware infrastructure (PCB with light emitting devices) supports all these functions through software control, eliminating the need for separate systems for each function.
2Manufacturing precision
If light emitting devices are arranged to provide homogeneous distribution over a three-dimensional surface, then the lighting achieves uniform coverage and aesthetic quality, but the manufacturing process becomes complex due to the need for three-dimensional shaping
Solution Approach 1:
The invention transitions from traditional two-dimensional PCB lighting arrangements to three-dimensional surface integration. By mapping light emitting devices onto a three-dimensional surface while maintaining even distribution, the system achieves uniform lighting coverage that adapts to complex geometric shapes, thereby improving aesthetic quality and functional uniformity without excessive manufacturing complexity.
3Adaptability or versatility
If multiple light emitting devices are integrated into traditional interior components like dashboard or door panels, then the lighting adds value and enhances user experience, but the integration process becomes more complex
Solution Approach 1:
The lighting system is merged with traditional interior components such as dashboard panels, door panels, and seat surfaces. The PCB with light emitting devices is integrated directly into these components, combining the lighting function with existing structural elements. This approach adds value and enhances user experience while leveraging existing component geometries to minimize integration complexity.
