Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiver renegotiates power needs at any time during reverse wireless charging, then the receiver can adapt to changing power demands, but the power transfer link may drop and require renegotiation, reducing charging efficiency
Solution Approach 1:
The patent implements dynamic power management where the transmitter proactively adjusts power delivery based on real-time system load conditions. The battery management module continuously monitors power demands and dynamically varies power transfer from the wireless transmission module, allowing the system to adapt to changing conditions without link drops. This dynamic approach resolves the contradiction by enabling adaptation while maintaining stable power transfer.
Solution Approach 2:
The system employs feedback mechanisms where the transmitter monitors system load and power demands, then adjusts power transfer accordingly. The battery management module receives feedback about power demands from various system loads and uses this information to control the wireless power transmission, preventing link drops while maintaining adaptability to changing power needs.
2Reliability
If the transmitter adheres to negotiated power demands of the receiver, then the power transfer link remains stable, but the transmitter cannot efficiently manage peak power delivery to various system loads
Solution Approach 1:
The patent enables dynamic power adjustment where the transmitter can vary power delivery in real-time based on system conditions. The battery management module continuously monitors power demands and adjusts the power transfer from the wireless transmission module accordingly, allowing the system to meet peak power demands while maintaining link stability through controlled adjustments rather than rigid adherence to initial negotiations.
Solution Approach 2:
The system changes power delivery parameters dynamically based on system load conditions. The battery management module adjusts transmission power levels, duty cycles, or voltage parameters in real-time to match actual system demands, enabling efficient peak power delivery while maintaining stable power transfer through continuous parameter optimization.
3Reliability
If power management circuitry throttles power to system loads to prevent battery brownout, then the battery is protected, but charging efficiency is reduced due to power limitations
Solution Approach 1:
The patent implements dynamic power management that adjusts power delivery based on real-time battery status and system demands. Rather than static throttling, the battery management module continuously monitors battery charge levels, temperature, and power demands, then dynamically adjusts power transfer rates. This allows the system to maximize charging efficiency while providing battery protection through adaptive control rather than fixed limitations.
Solution Approach 2:
The system changes power delivery parameters dynamically based on battery conditions. The battery management module adjusts transmission power, voltage, or current parameters in real-time according to battery state of charge, temperature, and health metrics. This enables efficient charging by optimizing power parameters while maintaining battery protection through condition-based parameter adjustments rather than fixed throttling.
