Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light sources are arranged in a matrix with small spacing to achieve high angular resolution, then angular resolution is improved, but manufacturing precision requirements increase
Solution Approach 1:
The display is segmented into multiple optical elements (lenses) arranged in a matrix, with each lens handling light from specific light sources. This segmentation allows the system to achieve high angular resolution through the combined effect of multiple elements rather than requiring extremely precise positioning of a single element, thereby reducing individual manufacturing precision requirements while maintaining overall system performance.
Solution Approach 2:
The patent employs light sources with different wavelengths (colors) and controls their activation patterns to achieve directional light projection. By changing the activation state of individual light sources in the matrix and utilizing wavelength diversity, the system achieves high angular resolution through parameter control rather than relying solely on precise physical spacing, thus mitigating manufacturing precision challenges.
2Adaptability or versatility
If multiple light sources are used to display information in different directions, then directional display capability is improved, but device complexity increases
Solution Approach 1:
Each optical element (lens) in the matrix serves multiple functions: it collects light from multiple light sources, directs light in specific directions, and contributes to forming images visible from different angles. This multi-functionality reduces the need for separate components for each function, thereby managing device complexity while achieving versatile directional display capability.
Solution Approach 2:
The patent combines multiple light sources and multiple optical elements into an integrated matrix structure where light sources are positioned behind corresponding lenses. This merging of components into a unified array allows the system to achieve complex directional display capabilities through coordinated operation of the combined structure, rather than requiring separate systems for each function, thus managing overall device complexity.
3Manufacturing precision
If light sources are spaced closely to increase resolution, then image resolution is improved, but light source spacing control becomes more difficult
Solution Approach 1:
The patent replaces mechanical positioning challenges with optical principles. Instead of relying solely on precise mechanical spacing of light sources, the system uses optical elements (lenses) with specific focal lengths and positioning to achieve the desired light direction and image resolution. This substitution of mechanical precision requirements with optical design parameters makes the manufacturing process more feasible while maintaining high resolution.
