Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted using traditional encryption methods, then data security is maintained, but transmission time increases and information density remains low
Solution Approach 1:
The patent encodes data across multiple dimensions of laser pulse characteristics simultaneously (color/wavelength, polarization, intensity, duration, pulse shape), transforming a single-dimensional transmission approach into a multi-dimensional encoding scheme. This allows parallel information embedding in different laser properties, dramatically increasing information density while maintaining security through complex multi-layer encoding that is difficult to intercept or decode without authorization.
2Productivity
If data is encoded in multiple characteristics of laser beam, then information density increases and transmission time reduces, but system complexity increases
Solution Approach 1:
The laser pulse serves multiple functions simultaneously as an information carrier: it modulates data across wavelength (color), polarization state, intensity amplitude, temporal duration, and pulse shape characteristics. This multi-functional approach allows a single laser pulse to embed multiple layers of information in parallel, achieving high information density without requiring separate transmission channels or multiple physical components, thereby managing system complexity efficiently.
3Device complexity
If traditional single-characteristic laser encoding is used, then system simplicity is maintained, but information density remains low and transmission time increases
Solution Approach 1:
The patent segments the laser pulse into multiple independent controllable characteristics (color/wavelength, polarization, intensity, duration, pulse shape), where each characteristic can independently carry a portion of the encoded data. This segmentation allows parallel information embedding across different laser properties, transforming a single-characteristic low-density system into a multi-characteristic high-density system while maintaining manageable complexity through modular encoding of each segment.
