Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the output voltage of the power supply is maintained at a fixed value, then the computing power and stability of the data processing device are ensured at low temperatures, but power consumption is wasted at high temperatures
Solution Approach 1:
The patent implements dynamic voltage adjustment by transitioning from a fixed voltage output to a variable voltage output that adapts to temperature changes. The power supply dynamically modifies its output voltage based on real-time temperature monitoring and computing power ratio calculations, allowing the system to optimize energy consumption while maintaining operational stability across varying thermal conditions
Solution Approach 2:
The patent changes the voltage parameter of the power supply based on temperature conditions and computing power ratios. By adjusting the output voltage as a variable parameter rather than maintaining it as a constant, the system achieves optimal balance between power consumption and computing power stability under different operating conditions
2Use of energy by moving object
If the output voltage of the power supply is reduced to save power at high temperatures, then power consumption is optimized, but computing power and stability are compromised
Solution Approach 1:
The patent implements a feedback control mechanism where the system continuously monitors temperature, calculates the computing power ratio, and adjusts the voltage accordingly. This closed-loop feedback ensures that voltage reduction decisions are made based on actual system performance data, preventing excessive voltage reduction that would compromise computing power stability while still achieving power optimization when conditions permit
Solution Approach 2:
The patent performs preliminary assessment of the computing power ratio before adjusting voltage levels. By evaluating whether the actual computing power meets the theoretical computing power threshold before reducing voltage, the system ensures that power consumption is optimized only when computing power requirements are satisfied, thereby maintaining stability while saving energy
3Use of energy by moving object
If automatic voltage regulation is implemented based on temperature and computing power ratio, then power consumption is optimized and computing power stability is maintained, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the existing control board of the data processing device. The control board simultaneously performs temperature monitoring, computing power ratio calculation, voltage adjustment decisions, and actual voltage regulation. By making the existing component multi-functional rather than adding separate dedicated components for each function, the system achieves automatic voltage regulation with minimal increase in overall device complexity
