Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display uses a single light source and optical element configuration, then the device complexity is low, but the display can only project information in one fixed direction
Solution Approach 1:
The display system is segmented into multiple independent light sources (first light source, second light source, etc.) with corresponding optical elements for each. Each light source-optical element pair can independently direct light in a specific direction, enabling the display to project information in multiple directions simultaneously or selectively, thus achieving directional flexibility without requiring a single complex movable system
Solution Approach 2:
The patent transitions from a single-direction display to multi-directional display by adding spatial dimensionality. Multiple light sources are arranged at different positions and angles, with each optical element directing light along a different spatial path. This dimensional expansion allows information to be displayed in multiple directions without mechanical movement, resolving the contradiction between versatility and complexity
2Measurement precision
If light sources are spaced far apart, then each light source can be controlled independently for directional display, but the angular resolution decreases
Solution Approach 1:
Each optical element is designed with specific local optical properties (lens shape, focal length, orientation) tailored to its position and desired output direction. This local optimization allows each light source-optical element pair to achieve high angular resolution in its specific direction while maintaining independent controllability, resolving the contradiction between resolution and versatility
Solution Approach 2:
The optical elements are pre-configured with specific geometries and orientations during manufacturing to direct light from each light source in predetermined directions. This preliminary configuration ensures high angular resolution is achieved without requiring real-time adjustment, allowing independent control of multiple light sources while maintaining precision
3Adaptability or versatility
If multiple optical elements are used to display information in multiple directions, then the display versatility improves, but the device complexity increases
Solution Approach 1:
Each optical element is designed as a universal component that can effectively handle light from its associated light source and direct it in the required direction. The optical elements share common design principles and can be manufactured using similar processes, reducing overall system complexity despite the increased number of components. This universality allows multi-directional display while controlling complexity through standardized component design
