Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing automotive ambient lights only use color changes, then the lighting structure remains simple, but the visual effect becomes monotonous and fails to meet diverse consumer needs
Solution Approach 1:
The lighting system is segmented into multiple LED units, each with independent control capabilities. Each LED unit can be individually adjusted in terms of light emission state, color, and projection shape, enabling diverse lighting effects while maintaining modular simplicity in the overall structure
Solution Approach 2:
The patent introduces dynamic control capabilities where LED units can switch between different light emission states (on/off individual color modules) and the projection shape can dynamically change between stripe and spot patterns. This dynamic adjustability provides visual diversity without requiring multiple fixed lighting systems
2Adaptability or versatility
If multiple LED units with different light-emitting modules are used to achieve dynamic strip changes, then the light effect diversity increases, but the device complexity and cost increase
Solution Approach 1:
Multiple functional elements are merged into integrated components. The LED units combine multiple light-emitting modules (red, green, blue) within single units, and the control system merges adjustment capabilities for color, brightness, and projection shape into a unified control framework. This reduces the number of separate components needed while achieving complex lighting effects
Solution Approach 2:
The LED units are designed with multi-functionality, capable of performing multiple functions: emitting different colors, adjusting brightness levels, and changing projection shapes. This universal design allows a single component to replace what would traditionally require multiple specialized components, reducing overall system complexity
