Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional single-layer quantum encoding is used, then the system is simpler to implement, but the information capacity is limited
Solution Approach 1:
The patent transitions from traditional single-layer quantum encoding to double-helix multi-layer spatial encoding, adding a spatial dimension to the encoding structure. This allows multiple layers of information to be encoded simultaneously in different spatial positions along the helical structure, dramatically increasing information capacity without requiring multiple separate transmission channels
Solution Approach 2:
The patent implements nested encoding where classical information is embedded within quantum states, which are in turn encoded along the spatial coordinates of the double-helix structure. This multi-level nesting approach (classical → quantum → spatial) allows dense information packing while maintaining a unified transmission system
2Reliability
If quantum communication is implemented without spatial encoding, then the system is easier to operate, but security against eavesdropping is vulnerable
Solution Approach 1:
The patent adds spatial coordinates along the double-helix structure as an additional dimension for encoding quantum states. This spatial dimension provides extra security layers because eavesdroppers would need to intercept and correctly interpret both the quantum states and their spatial positions, making undetected eavesdropping significantly more difficult
Solution Approach 2:
The patent creates a composite encoding system that integrates classical information, quantum states, and spatial coordinates into a unified double-helix structure. This composite approach combines the security benefits of quantum mechanics with the structural advantages of spatial encoding, creating a multi-layered security architecture resistant to various types of attacks
3Quantity of substance
If quantum states are transmitted without multi-layer encoding, then the system has lower information density, but the transmission is more resistant to noise and interference
Solution Approach 1:
The patent segments information into multiple independent layers encoded at different spatial positions along the double-helix structure. Each spatial position carries its own quantum-encoded information, allowing the system to transmit multiple data streams simultaneously. This segmentation increases information density while providing redundancy against noise affecting individual positions
Solution Approach 2:
The patent utilizes multiple quantum state parameters (polarization, phase, orbital angular momentum) combined with spatial coordinates to encode information. By changing and utilizing multiple parameters simultaneously rather than relying on a single parameter, the system achieves higher information density while the diversity of parameters provides inherent noise resistance through parameter diversity
