Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed transmission paths are used for RF signals, then device complexity is reduced, but energy efficiency and adaptability to environmental changes deteriorate
Solution Approach 1:
The patent implements dynamic transmission path selection where the system can reconfigure which power amplifiers and antennas are connected based on real-time conditions. The processor dynamically determines transmission paths by considering pathloss values and power amplifier capabilities, allowing the system to adapt to changing environmental conditions rather than using fixed connections.
Solution Approach 2:
The system changes operational parameters by selecting different transmission paths based on calculated pathloss values and power amplifier output capabilities. The processor adjusts the mapping between power amplifiers and antennas according to varying channel conditions, effectively changing the transmission parameters to optimize energy efficiency while maintaining adaptability.
2Power
If power amplifiers operate at maximum capacity continuously, then transmission power is sufficient, but energy consumption increases
Solution Approach 1:
The patent applies local quality by matching individual power amplifier capabilities to specific transmission path requirements. Each power amplifier is assigned to a transmission path based on its specific output capability and the pathloss characteristics of that path, ensuring that each component operates at its optimal point rather than all components operating at maximum capacity uniformly.
Solution Approach 2:
The system dynamically adjusts the operational parameters of power amplifiers by selecting transmission paths that match the actual power requirements. The processor determines optimal power levels for each amplifier based on the chosen transmission path and its characteristics, allowing amplifiers to operate at appropriate power levels rather than continuous maximum capacity.
3Use of energy by moving object
If multiple transmission paths are available, then energy efficiency improves, but system complexity and configuration difficulty increase
Solution Approach 1:
The system performs self-service by automatically determining optimal transmission paths without manual configuration. The processor autonomously calculates pathloss values, compares power amplifier capabilities, and selects the most energy-efficient transmission paths, eliminating the need for complex manual setup while still providing multiple path options for optimization.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors transmission conditions and adjusts power amplifier assignments accordingly. The processor uses feedback about pathloss and power amplifier performance to dynamically reconfigure transmission paths, allowing the system to learn from actual performance and optimize energy efficiency over time.
