Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If special glasses or complicated mechanisms are used for three-dimensional image display, then three-dimensional image display capability is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the complex optical components (special glasses, complicated mechanisms) from the display system and replaces them with a simplified light guide matrix approach. The image information is directly projected onto the light guides without requiring external optical辅助设备, thereby achieving three-dimensional display while reducing device complexity.
Solution Approach 2:
The patent replaces mechanical/optical mechanisms with a light-based system. Instead of using mechanical moving parts or complex optical paths, the invention uses light guides that directly transmit projected light to create three-dimensional images, substituting mechanical systems with optical field-based solutions.
2Productivity
If image information is decomposed into pixels, then image display is achieved, but image quality suffers
Solution Approach 1:
The patent uses the light guide matrix as an optical copy medium. Instead of decomposing image information into discrete pixels that lose quality, the continuous light field is copied and transmitted through the light guides, preserving the original image quality while achieving display functionality.
3Adaptability or versatility
If multiple radiation spectra are used for projection, then functionality is enhanced, but device complexity increases
Solution Approach 1:
The patent makes the light guide matrix universal by enabling it to handle multiple radiation spectra (visible, infrared, ultraviolet). The same light guide structure serves multiple functions across different spectral ranges, allowing enhanced functionality without proportionally increasing device complexity.
