Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is increased to maintain communication link quality, then communication reliability is improved, but emissions control compliance deteriorates as the transmitted energy may exceed acceptable thresholds and betray platform existence
Solution Approach 1:
The system dynamically adjusts transmission power based on real-time assessment of adversary detection probability and communication requirements. The emissions management module continuously monitors operational conditions and modifies power levels adaptively, transitioning from static power settings to dynamic control that responds to changing threat environments and link quality needs.
Solution Approach 2:
The system changes the power parameter of electromagnetic transmissions based on calculated detection probabilities and communication quality requirements. By adjusting transmission power as a variable parameter rather than maintaining a fixed level, the system optimizes the balance between maintaining reliable communication and minimizing detectable emissions.
2Object-affected harmful factors
If emissions control restrictions are strictly enforced to avoid detection, then platform stealth is improved, but communication reliability deteriorates due to limited transmission power and potential link degradation
Solution Approach 1:
The system implements feedback loops where communication link quality metrics are continuously monitored and fed back to the emissions management module. This feedback enables the system to assess whether current power restrictions are degrading link quality below acceptable thresholds and to adjust emissions accordingly while maintaining overall stealth objectives.
Solution Approach 2:
The emissions control regime transitions from static, pre-defined restrictions to dynamic adjustments based on real-time communication performance monitoring. The system adaptively modifies transmission parameters within EMCON constraints to maintain adequate link quality when communication reliability becomes critical.
3Adaptability or versatility
If multiple communications links and systems operate simultaneously on the same platform, then communication versatility is improved, but interference between systems increases leading to signal degradation
Solution Approach 1:
The system applies different power levels and transmission characteristics to different communication links based on their specific requirements and interference potential. Rather than uniform power allocation, each link receives optimized local parameters that account for its unique communication needs and interference relationships with other onboard systems.
Solution Approach 2:
The emissions management module dynamically adjusts transmission parameters (power, timing, frequency) for multiple co-located communication systems to minimize mutual interference. By varying parameters across different links rather than maintaining fixed settings, the system enables simultaneous operation of multiple communication channels with reduced interference.
4Object-affected harmful factors
If dynamic adaptation of transmission power is implemented to respond to changing operational conditions, then emissions control compliance is improved, but system complexity increases due to additional management requirements
Solution Approach 1:
The emissions management module serves multiple functions simultaneously: it calculates adversary detection probability, determines compliant power levels, monitors link quality, and adjusts transmission parameters. By consolidating these previously separate functions into a single multi-functional module, the system achieves dynamic emissions control without proportionally increasing overall system complexity.
Solution Approach 2:
The system merges emissions control calculations, power level determination, and transmission management into an integrated emissions management module. This consolidation combines multiple management functions that would otherwise require separate systems, reducing the net increase in complexity while enabling sophisticated dynamic adaptation to EMCON conditions.
