Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed operating frequencies are used for resources, then device simplicity is maintained, but power consumption efficiency deteriorates leading to overheating and reduced performance
Solution Approach 1:
The patent implements dynamic frequency adjustment by dividing operation periods into multiple partial operation periods with different frequencies. The frequency adjuster dynamically selects operating frequencies based on power budgets and resource priorities, transforming the static frequency system into an adaptive dynamic system that optimizes power consumption while maintaining performance.
Solution Approach 2:
The patent changes the operating frequency parameter of resources based on power consumption requirements. By adjusting the frequency parameter dynamically according to available power budgets and resource priorities, the system achieves efficient power management without requiring complete system redesign.
2Productivity
If operating frequencies are increased to maintain performance, then productivity is improved, but power consumption increases leading to overheating
Solution Approach 1:
The patent segments the operation period into multiple partial operation periods, each with different frequency settings. During high-priority operations, higher frequencies are used to maintain productivity, while during low-priority operations, lower frequencies reduce power consumption. This segmentation allows the system to balance performance and energy loss across different operational phases.
Solution Approach 2:
The frequency adjuster performs periodic frequency adjustments at predetermined adjustment timings. By periodically evaluating power budgets and resource priorities, the system cycles through different frequency configurations, ensuring that high performance is achieved when needed while accepting lower performance during periods when power conservation is prioritized.
3Loss of energy
If power consumption is reduced by lowering frequencies, then energy efficiency is improved, but operation lifespan is shortened due to insufficient processing capability
Solution Approach 1:
The frequency adjuster implements a feedback mechanism that continuously monitors power consumption, power budgets, and resource priorities. Based on this feedback, the system dynamically adjusts frequencies to ensure that power consumption remains within acceptable limits while maintaining sufficient processing capability to complete operations within the device's operational lifespan.
Solution Approach 2:
The system dynamically adapts frequency settings based on real-time conditions rather than using fixed low frequencies. This dynamic adjustment ensures that when power is available and operations are critical, higher frequencies extend the effective operational lifespan by completing tasks faster, while during low-power states, lower frequencies conserve energy.
4Use of energy by moving object
If dynamic frequency adjustment is implemented, then power management efficiency is improved, but device complexity increases
Solution Approach 1:
The frequency adjuster is designed as a universal component that manages multiple resources with different priorities and power requirements. Rather than implementing separate control mechanisms for each resource, the single frequency adjuster handles frequency optimization across all resources, reducing overall system complexity while maintaining power management efficiency.
Solution Approach 2:
The system manages complexity by focusing parameter changes primarily on frequency rather than redesigning entire resource management architectures. By implementing a relatively simple frequency adjustment mechanism that modifies operating parameters rather than structural components, the patent achieves improved power management with minimal increase in device complexity.
