Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OAM twisted wave technology is used for communication, then data throughput and signal selectivity are improved, but device complexity increases and reliability decreases due to specialized equipment requirements and sensitivity to antenna misalignment
Solution Approach 1:
The patent changes the fundamental parameters of radio wave communication by using CTwists waves with twist frequencies lower than carrier frequencies, enabling detection with standard FFT processors. This parameter change resolves the contradiction by maintaining high data throughput while eliminating the need for specialized OAM equipment.
Solution Approach 2:
The patent substitutes the complex mechanical alignment requirements of OAM systems with a field-based detection method using CTwists waves. The twisted wave pattern is detected through its electromagnetic field characteristics rather than requiring precise mechanical antenna alignment, thereby reducing device complexity and improving reliability.
2Productivity
If wide spectrum frequencies are used for communication, then data throughput is improved, but harmful factors increase due to interference with legacy radio waves
Solution Approach 1:
The patent uses CTwists waves with twist frequencies lower than carrier frequencies, creating ultra-narrow band transmissions. This parameter change allows high data throughput through efficient spectrum utilization while minimizing wide spectrum emissions that would interfere with legacy radio waves.
Solution Approach 2:
The patent segments the communication signal into ultra-narrow frequency bands using CTwists wave technology. By dividing the transmission into precise frequency segments rather than using wide spectrum emissions, the system achieves high throughput while reducing interference with other radio wave users.
3Adaptability or versatility
If radio frequency substance detection is performed, then substance detection capability is improved, but measurement precision is limited due to the vast number of excitation frequency lines in the 10 KHz to 100 GHz range
Solution Approach 1:
The patent changes the detection approach by using CTwists waves with twist frequencies lower than carrier frequencies. This creates ultra-narrow band excitation lines that are easily distinguishable, resolving the precision problem while maintaining versatility in substance detection across the radio frequency spectrum.
