Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the frequency and capacity of memory modules are increased to meet higher performance demands, then the data processing capability is improved, but the temperature and power consumption increase leading to performance degradation
Solution Approach 1:
The power supply system is segmented into multiple independent power control components, each responsible for specific memory units or functional blocks. This segmentation allows for localized power management and targeted cooling strategies, reducing overall system temperature while maintaining high performance capability.
Solution Approach 2:
The patent dynamically adjusts power supply parameters (voltage, current) based on operational demands and temperature conditions. By changing electrical parameters in response to thermal conditions, the system maintains optimal performance while preventing excessive heat generation that would degrade memory performance.
2Productivity
If the frequency and capacity of memory modules are increased to meet higher performance demands, then the data processing capability is improved, but the power consumption increases
Solution Approach 1:
The power control components dynamically adjust power delivery based on real-time operational requirements. Instead of providing constant maximum power, the system adapts power levels to match actual data processing demands, reducing overall power consumption while maintaining high productivity when needed.
Solution Approach 2:
Electrical parameters including voltage and current are dynamically changed based on operational mode and performance requirements. This allows the system to achieve high data processing capability only when necessary, while operating at lower power consumption during normal conditions.
3Device complexity
If a single power supply system is used for all memory components, then the device complexity is reduced, but the power consumption and heat generation increase
Solution Approach 1:
The power supply system is divided into multiple independent power control components, each managing specific subsets of memory units or functional blocks. This segmentation enables finer-grained power management, allowing individual components to be powered down or reduced when not in use, thereby reducing overall power consumption despite increased structural complexity.
4Speed
If higher voltage is provided to all memory components, then the operating speed is improved, but the power consumption and heat generation increase
Solution Approach 1:
Different voltage levels are provided to different memory components or functional blocks based on their specific performance requirements. Critical high-speed components receive higher voltage for optimal operating speed, while less demanding components operate at lower voltages to reduce overall power consumption and heat generation.
