Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If voltage is increased to meet higher current demands of components, then power delivery capability is improved, but power consumption and heat generation increase
Solution Approach 1:
The patent implements dynamic voltage adjustment by continuously monitoring component states (active, idle, sleep) and adjusting the voltage level accordingly. The processor transitions between different voltage levels based on real-time component demands, ensuring voltage is increased only when necessary to meet current demands, thereby improving power delivery capability while minimizing unnecessary power consumption and heat generation.
Solution Approach 2:
The system changes the voltage parameter dynamically based on component operational states. When a component transitions from idle to active state, the voltage is increased to meet higher current demands. When the component returns to idle or sleep state, the voltage is reduced. This parameter change approach ensures optimal power delivery while reducing energy loss during low-demand periods.
2Loss of energy
If voltage is dynamically adjusted based on component states, then power efficiency is improved, but system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the processor continuously monitors component states (active, idle, sleep) and uses this information to adjust voltage levels. The system receives feedback about component operational status and responds by transitioning between predefined voltage levels. This feedback-driven approach improves power efficiency while keeping the control logic relatively simple through standardized state transitions.
Solution Approach 2:
The system performs self-service by automatically monitoring its own component states and adjusting voltage levels without external intervention. The processor independently detects component state changes and triggers appropriate voltage transitions, reducing the need for complex external control mechanisms while maintaining improved power efficiency.
3Adaptability or versatility
If multiple regulating circuits are used to serve different components, then adaptability to different power demands is improved, but device complexity increases
Solution Approach 1:
The patent divides the power management system into multiple regulating circuits, each dedicated to serving specific components or component groups with similar power demands. This segmentation allows each regulating circuit to be optimized for its specific function while collectively providing adaptability to diverse power requirements across different components in the electronic device.
Solution Approach 2:
The regulating circuits are designed with multi-functionality to handle different operational states (active, idle, sleep) of their associated components. Each regulating circuit can transition between different voltage levels to serve its component in various states, providing universal adaptability without requiring separate dedicated circuits for each state, thus balancing adaptability with controlled complexity.
