Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If radio-wave based communication is used, then communication coverage is achieved, but bandwidth and security are limited
Solution Approach 1:
The patent replaces radio-wave based electromagnetic communication with optical communication using modulated light beams. This substitution enables higher bandwidth through optical carrier waves and improved security through directional narrowcasting that does not penetrate walls, directly resolving the contradiction between bandwidth and security limitations of radio-wave systems
Solution Approach 2:
The patent changes the fundamental parameter of communication from radio frequency electromagnetic waves to optical frequency light waves. This parameter change enables transmission of information at visible or near-visible frequencies, providing both higher bandwidth capacity and enhanced security through line-of-sight directional transmission that cannot pass through solid obstacles
2Reliability
If directional optical transmission is used, then security and bandwidth are improved, but transmission distance is reduced
Solution Approach 1:
The patent employs periodic modulation of optical beams at visible or near-visible frequencies to transmit information. This periodic action enables the use of high-frequency optical carriers that can be modulated to carry data while maintaining directional propagation, achieving both security through directionality and extended transmission distance through efficient optical carrier utilization
Solution Approach 2:
The optical communication system is designed to serve multiple functions: directional narrowcasting for security, long-range transmission for coverage, and high-bandwidth data transfer for gaming applications. By integrating these multiple functions into a single optical communication platform, the system overcomes the apparent trade-off between directionality and transmission distance
3Quantity of substance
If optical narrowcasting is used, then bandwidth and security are enhanced, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary optical modulation system that converts digital game data into modulated optical signals. This intermediary layer handles the complexity of optical carrier modulation, beam directionality control, and signal demodulation, allowing the core gaming system to benefit from high-bandwidth optical communication without directly managing the complexity of optical signal processing
