Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power supply and communication functions are integrated in a single system, then device complexity is reduced, but flexibility of power supply management deteriorates
Solution Approach 1:
The patent segments the power supply device into distinct functional modules: a power supply module with multiple power supply ports and a communication module with communication ports. Each module operates independently but can be coordinated through the controller, allowing flexible power management while maintaining system integration. This segmentation enables different power policies to be applied to different loads without increasing overall system complexity.
2Adaptability or versatility
If power supply cable and communication cable are physically isolated, then power supply flexibility is improved, but system complexity increases
Solution Approach 1:
The patent physically isolates power supply cables from communication cables, with power supply ports connected via power supply cables and communication ports connected via communication cables. This segmentation allows independent optimization of power delivery and communication functions while the controller coordinates their interaction to manage overall system complexity.
Solution Approach 2:
The controller acts as an intermediary between the power supply module and communication module, coordinating their operations. It processes communication signals to determine power requirements and adjusts power supply accordingly, enabling flexible power management without direct coupling between power and communication subsystems.
3Loss of energy
If power threshold is dynamically adjusted based on load requirements, then power efficiency is improved, but control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the controller receives communication signals from loads indicating their power requirements and dynamically adjusts power supply thresholds accordingly. This feedback loop enables efficient power allocation by matching supply to actual demand, reducing power waste while managing control complexity through automated decision-making algorithms.
Solution Approach 2:
The patent employs dynamic power threshold adjustment where power supply limits are not fixed but change based on real-time load requirements communicated through the communication interface. This dynamic approach allows the system to adapt power allocation to varying operational conditions, improving efficiency while the controller manages the complexity of real-time adjustments.
