Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional headlight illumination methods are used, then the basic illumination function is achieved, but the lighting experience is static and lacks interaction with environmental conditions
Solution Approach 1:
The patent applies dynamics by transforming the static headlight illumination into a dynamic system that continuously adapts to environmental conditions. The polygon mesh structure and its properties (brightness, size, shape) are dynamically adjusted based on detected environmental features such as temperature, humidity, and atmospheric conditions, creating a living, interactive lighting experience rather than a fixed illumination pattern
Solution Approach 2:
The patent implements feedback mechanisms by using sensors to detect environmental conditions and then adjusting the headlight illumination accordingly. The system creates a closed-loop control where environmental data feeds back to modify the polygon mesh parameters, enabling the lighting system to respond intelligently to changes in the surrounding environment
2Loss of information
If polygon mesh with different brightness levels is projected, then visual interest and information transmission are improved, but the system complexity increases
Solution Approach 1:
The patent applies local quality by assigning different properties to different regions of the polygon mesh. Each polygon or group of polygons can have distinct brightness levels, sizes, and visual characteristics based on the local environmental conditions detected in corresponding areas. This allows selective adaptation of different parts of the illumination pattern rather than uniform changes across the entire field
Solution Approach 2:
The patent segments the headlight illumination into a polygon mesh structure where individual polygons or groups of polygons can be independently controlled. This segmentation enables different regions to convey different information or respond to different environmental conditions, increasing the information transmission capability while maintaining manageable system complexity through modular control
3Adaptability or versatility
If the light pattern is dynamically adapted in real-time, then interactivity and engagement are enhanced, but the computational requirements and system complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-defining the polygon mesh structure and establishing the framework for adaptation before real-time operation. The basic geometric framework and adaptation rules are prepared in advance, allowing the system to focus computational resources on adjusting parameters within the pre-established structure rather than creating the entire illumination pattern from scratch in real-time
