Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional bulb-shaped light emitting units are used, then the structure is simple and easy to manufacture, but the light spot pattern is monotonous and limited to circular shapes
Solution Approach 1:
The light emitting unit is divided into multiple independent lens bodies (first lens body, second lens body, third lens body) arranged in specific patterns. Each lens body can be independently designed with different shapes and optical properties, allowing the system to generate complex light spot patterns while maintaining modular manufacturing simplicity.
Solution Approach 2:
Different regions of the lens module are assigned different optical functions and shapes. The first lens body creates a first light spot pattern, the second lens body creates a second light spot pattern, and the third lens body creates a third light spot pattern. Each local region has specialized optical properties tailored to its specific function, enabling diverse patterns from a unified structure.
2Adaptability or versatility
If multiple separate light emitting units are used to create different patterns, then the illumination patterns become diverse, but the device structure becomes complex
Solution Approach 1:
Multiple lens bodies (first lens body, second lens body, third lens body) are integrated into a single light emitting unit structure. These lens bodies work together to generate multiple distinct light spot patterns (first, second, and third patterns) from one unified device, eliminating the need for separate light emitting units while maintaining pattern diversity.
Solution Approach 2:
The light emitting unit is designed as a multi-functional device capable of generating at least three different light spot patterns through its multiple lens bodies. The same structural unit can adapt to different illumination requirements by activating different lens bodies or combinations, providing versatility without requiring multiple specialized units.
3Shape
If lens bodies are arranged to form complex predetermined shapes, then the visual interest and functionality are enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The complex predetermined shape is segmented into multiple independent lens bodies that can be manufactured separately with standard precision tolerances. Each lens body maintains its specific shape and optical properties independently, reducing the cumulative precision requirements compared to manufacturing a single complex shape as one piece.
