Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the input voltage is increased to ensure sufficient power supply to the information processing device, then the power consumption exceeds the charging voltage requirement, but the power efficiency deteriorates due to excessive voltage difference causing energy wastage
Solution Approach 1:
The patent applies dynamics by making the input voltage adjustable rather than fixed. The voltage converter dynamically changes the input voltage level based on real-time monitoring of the information processing device's power consumption. This allows the system to optimize the voltage difference between input and charging voltage, reducing energy wastage while ensuring sufficient power supply when needed.
Solution Approach 2:
The patent implements feedback control where the controller continuously monitors the power consumption of the information processing device and adjusts the input voltage accordingly. This closed-loop feedback mechanism ensures that the input voltage is optimized to match the actual power needs, preventing both energy wastage from excessive voltage and power deficiency from insufficient voltage.
2Loss of energy
If the input voltage is reduced to minimize power wastage, then the power efficiency improves, but the power supply becomes insufficient for the information processing device to operate
Solution Approach 1:
The system dynamically adjusts the input voltage based on the actual power consumption of the information processing device. Rather than using a fixed low voltage that would cause insufficiency, the voltage converter responds to changing power demands, ensuring adequate power supply while minimizing wastage through optimized voltage levels.
Solution Approach 2:
The controller uses feedback from power consumption monitoring to determine the appropriate input voltage level. This ensures that the voltage is never reduced to a level that would cause power insufficiency, while also preventing excessive voltage that would waste energy. The feedback loop maintains the optimal balance between power supply adequacy and energy efficiency.
3Reliability
If a fixed high charging voltage is used to ensure adequate power for all operating modes, then the power supply reliability improves, but the power efficiency deteriorates during low-power operating modes due to excessive voltage difference
Solution Approach 1:
The patent replaces the fixed high charging voltage with a dynamic voltage adjustment mechanism. The input voltage is adapted to match the information processing device's operating mode, providing high voltage when needed for reliability and reducing voltage during low-power modes to improve efficiency. This dynamic approach maintains power supply reliability across all operating conditions while eliminating unnecessary energy wastage.
Solution Approach 2:
The system applies local quality by tailoring the input voltage level to the specific operating conditions of the information processing device. Rather than using a uniformly high voltage for all modes, the voltage is locally optimized for each operating mode, ensuring adequate power supply for reliability while minimizing energy wastage in low-power modes.
4Adaptability or versatility
If the voltage converter operates with a large voltage difference between input and output to handle power fluctuations, then the adaptability to different power consumption levels improves, but the heat generation increases reducing overall system efficiency
Solution Approach 1:
The patent applies dynamics by continuously adjusting the input voltage to match the information processing device's power consumption level. This dynamic adjustment reduces the voltage difference during normal operation, thereby reducing heat generation. The system maintains adaptability to power fluctuations by responding to changes in real-time, only increasing the voltage difference when necessary to handle power demands.
Solution Approach 2:
The patent converts the potential harm of heat generation into a benefit by using temperature monitoring as part of the feedback control system. When temperature rises due to voltage conversion, the system responds by optimizing the voltage difference, thereby reducing further heat generation. This transforms the thermal issue into a control parameter that enhances overall system efficiency.
