Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single radiation source is used for data transmission, then the system is simple, but the transmission rate is limited
Solution Approach 1:
The invention divides the data transmission task across multiple radiation sources (at least two), where each source transmits a portion of the data simultaneously. This segmentation allows parallel transmission, thereby increasing the overall transmission rate while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The invention combines multiple radiation sources to work together in transmitting data. By merging the capabilities of multiple sources and using their collective output, the system achieves higher transmission rates than a single source could provide alone, while the coordinated operation maintains system simplicity.
2Reliability
If radiation sources are modulated at high frequency, then transmission is less susceptible to electromagnetic interference, but the intensity variation requires precise control
Solution Approach 1:
The invention employs periodic modulation of radiation source intensities at high carrier frequencies to encode data. This periodic action makes the transmission robust against electromagnetic interference while the structured nature of the modulation allows for manageable control complexity through established modulation techniques.
Solution Approach 2:
The invention changes the intensity parameter of radiation sources in a controlled manner to encode data. By varying intensity parameters at high frequencies with precise control, the system achieves resistance to electromagnetic interference while maintaining manageable control complexity through parameter-based encoding schemes.
3Productivity
If multiple radiation sources are used with phase relationships, then data transmission rate increases, but the system becomes more complex to synchronize
Solution Approach 1:
The invention introduces a temporal dimension through phase relationships between multiple radiation sources. By encoding data in the phase differences of carrier frequencies, the system achieves higher transmission rates while the phase-based encoding provides a structured framework that manages synchronization complexity.
Solution Approach 2:
The invention uses dynamic phase relationships between radiation sources to encode and transmit data. The phase positions are varied dynamically to convey information, increasing transmission rate while the dynamic nature of phase modulation provides flexibility in managing synchronization through adaptive encoding schemes.
4Illumination intensity
If visible light sources are used for data transmission, then illumination is provided simultaneously, but the transmission can be detected by humans
Solution Approach 1:
The invention uses high-frequency periodic modulation of visible light sources to transmit data. The rapid intensity variations occur at frequencies beyond human perception, allowing the light to serve both illumination and data transmission functions simultaneously while making the transmission undetectable to human observers.
Solution Approach 2:
The invention changes the intensity parameter of visible light sources at high frequencies to encode data. These rapid parameter changes enable simultaneous illumination and data transmission while the high-frequency variations remain imperceptible to humans, effectively hiding the transmission from human detection.
5Object-affected harmful factors
If non-visible light sources are used, then transmission security is improved, but illumination capability is lost
Solution Approach 1:
The invention employs visible light sources that can perform multiple functions: providing illumination and transmitting data securely. By using phase modulation at high frequencies, the same visible light source achieves both illumination and secure transmission, eliminating the need for separate non-visible light sources.
