Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AC/DC adapter immediately stops supplying power when overloading is detected, then safety hazards are avoided, but the electronic device may crash and user convenience deteriorates
Solution Approach 1:
The patent applies dynamics by making the power supply system adaptable and responsive to changing load conditions. The charge controller dynamically adjusts charging parameters based on real-time feedback from the adapter, allowing the system to transition between different operational states (normal charging, overload protection, power distribution) without sudden shutdowns, thereby maintaining both safety and user convenience
Solution Approach 2:
The patent implements feedback control where the charge controller receives status information from the adapter and adjusts charging parameters accordingly. This closed-loop control enables the system to respond to overload conditions by modulating charge current or voltage rather than immediately shutting down, preventing system crashes while maintaining safety through controlled power management
2Power
If the charge current is increased to meet system power requirements, then power sufficiency is improved, but the risk of overloading and safety hazards increases
Solution Approach 1:
The system dynamically adjusts charge current based on real-time monitoring of adapter output capacity and system power requirements. The charge controller can increase current when the adapter has excess capacity and reduce current when approaching overload thresholds, enabling the system to safely utilize the maximum available power without exceeding safety limits
Solution Approach 2:
The patent changes operating parameters (charge current, voltage) based on adapter status feedback. By continuously monitoring adapter output capabilities and adjusting charging parameters accordingly, the system can safely operate at higher power levels when conditions permit while automatically reducing power to prevent overload, thus resolving the contradiction between power sufficiency and safety
3Power
If the adapter output voltage is increased to provide sufficient power to the system, then power requirement fulfillment is improved, but power loss and energy waste increase
Solution Approach 1:
The system dynamically adjusts the adapter output voltage based on the actual power requirements of the battery and system. Rather than maintaining a fixed high voltage that would cause energy waste, the charge controller modulates voltage in real-time to match demand, ensuring sufficient power delivery while minimizing unnecessary energy loss in the power conversion and distribution process
Solution Approach 2:
The patent implements parameter changes by adjusting output voltage and current based on feedback about system needs. When the system requires less power, the adapter operates at lower voltage/current levels, reducing resistive losses and improving overall efficiency. When full power is needed, parameters are increased accordingly, optimizing the balance between power delivery and energy efficiency
