Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-function circuitry is used to control power mode transitions, then the system structure is simple, but the adaptability and flexibility of power mode management are limited
Solution Approach 1:
The patent implements a programmable power mode sequencer that allows dynamic configuration of power mode transition sequences through context files and control signals. The system can be reprogrammed to handle different power mode scenarios without hardware changes, transforming the static fixed-function circuitry into a dynamic adaptable system.
Solution Approach 2:
The patent changes the operational parameters of the power mode controller by introducing programmable context files that define different power mode sequences. By modifying the control parameters (context selections, delay values, enable signals) rather than the hardware structure, the system achieves flexibility while maintaining structural simplicity.
2Adaptability or versatility
If programmable contexts are introduced to enable flexible power mode transitions, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The power mode sequencer is designed as a universal controller that can manage multiple power modes (active, standby, sleep, hibernate) and various electrical components through a single programmable structure. The context files serve as multi-functional configuration data that define different power mode sequences, allowing one device to perform multiple power management functions.
Solution Approach 2:
The patent introduces context files as an intermediary between the processor and the power mode sequencer. These files act as a mediator that translates high-level power mode requirements into specific control signals and sequences, reducing the complexity of direct hardware control while maintaining flexibility.
3Loss of energy
If multiple sequential operations are implemented for power mode transitions, then the power consumption management improves, but the transition time increases
Solution Approach 1:
The patent implements preliminary actions by preparing control signals and context configurations in advance before actual power mode transitions. The sequencer pre-configures the necessary control sequences based on selected contexts, allowing rapid execution during actual transitions without real-time computation delays.
Solution Approach 2:
The power mode transitions are structured as periodic sequential operations with defined phases (signal generation, component switching, state updates). This periodic structure allows the system to optimize each phase for both energy efficiency and timing, repeating the optimized sequence for different power modes.

AI summary
A system includes a context file to store multiple contexts corresponding to different power modes of an electronic system, and a domain control device to generate control signals based, at least in part, on a context from the context file. The electronic system is configured to transition to a power mode corresponding to the context responsive to the control signals.
