Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If software-based modeling tools are used, then design iterations can be performed before hardware fabrication, but the tools cannot handle high-speed data rates and are non-deterministic
Solution Approach 1:
The patent replaces software-based modeling with hardware-based modeling using FPGAs. This substitution eliminates the non-deterministic nature of software processing (processor time division multiplexing, memory reads/writes) by using dedicated hardware circuits that provide deterministic, real-time processing of high-speed data streams while maintaining the ability to perform design iterations before final hardware fabrication.
2Adaptability or versatility
If software-based modeling tools are used, then design iterations can be performed, but they are constrained in handling data rates required for real-time simulation
Solution Approach 1:
The patent substitutes software-based processing with hardware-based processing using FPGAs. This enables the system to handle high-speed data rates required for real-time simulation of high-speed data stream handling and communications channels, while maintaining adaptability through reconfigurable hardware logic that can be programmed to model different scenarios.
3Manufacturing precision
If multiple iterations of hardware creating and testing are performed, then design suitability can be improved, but expense and development time increase significantly
Solution Approach 1:
The patent creates a hardware model (copy) of the communication system using FPGAs that can be used for multiple design iterations. This model allows engineers to test and validate designs in hardware before committing to expensive final hardware fabrication, reducing both the number of expensive iterations needed and the overall development time while maintaining design suitability.
Solution Approach 2:
The patent performs preliminary hardware-based modeling and simulation using FPGAs before final hardware fabrication. This preliminary action allows design validation and optimization to occur in a hardware environment that accurately reflects real-time processing requirements, preventing costly redesigns after fabrication and reducing overall development time.
