Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional expendable active decoys are used, then they can generate electronic signatures for single aircraft, but they fail to protect large ground formations from electronic identification and targeting
Solution Approach 1:
The RF generator is designed to perform multiple functions by generating different types of waveforms (SDR, CDL, DDL) that can represent various military assets including ground troops and aircraft. This multi-functionality allows a single device to protect diverse military formations rather than being limited to single-aircraft decoying
Solution Approach 2:
The system changes its operational parameters by programmatically switching between different waveform types and configurations. The RF generator can be programmed to emit specific waveforms with particular characteristics (frequency, modulation, power levels) to match the electronic signatures of different military units, enabling adaptive protection across multiple scenarios
2Reliability
If multiple waveforms are transmitted simultaneously to mask military unit locations, then electronic counter-measures are enhanced, but device complexity increases
Solution Approach 1:
The patent replaces complex hardware-based waveform generation with software-defined radio (SDR) technology. By using programmable logic and software control to generate waveforms instead of dedicated hardware circuits for each waveform type, the system achieves multiple waveform capabilities with reduced physical complexity and greater flexibility
Solution Approach 2:
The system combines multiple waveform generation capabilities into a single integrated RF generator device. Rather than using separate devices for different waveform types, the patent merges SDR, CDL, and DDL waveform generation into one programmable system that can output multiple waveforms simultaneously or sequentially
