Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple high-speed data transmission interfaces are integrated to provide diverse transmission options, then adaptability and versatility are improved, but power consumption increases because interfaces operate in different power states independently
Solution Approach 1:
The patent merges the power state control of multiple independent high-speed data transmission interfaces (USB, SATA, PCIe) into a unified power management system. The control circuit synchronizes power states across all interfaces, combining their power management functions to achieve system-level power optimization rather than individual interface optimization, thereby reducing overall power consumption while maintaining adaptability.
Solution Approach 2:
The control circuit implements a universal power state coordination mechanism that manages multiple different interface types (USB, SATA, PCIe) through a single multi-functional control system. This universal controller can adapt to various interface standards and coordinate their power states collectively, enabling one system to perform multiple interface management functions efficiently.
2Productivity
If interfaces operate independently in different power states to maintain their individual performance, then transmission efficiency is preserved, but overall power saving efficiency deteriorates due to mismatched power modes
Solution Approach 1:
The control circuit implements a feedback mechanism that continuously monitors the power states of multiple interfaces and adjusts them collectively. When data transmission is detected on one interface, the control circuit receives feedback and coordinates power state transitions across all interfaces to maintain transmission efficiency while optimizing power savings during idle periods, preventing energy waste from mismatched states.
Solution Approach 2:
The system dynamically coordinates power states across multiple interfaces based on real-time transmission requirements. The control circuit enables dynamic transitions between different power modes (L0, L1, L2, L3 for PCIe; U0, U1, U2, U3 for USB; PHY_READY, Partial, Slumber for SATA) in a synchronized manner, allowing the system to adapt its power consumption dynamically while maintaining transmission efficiency when needed.
3Productivity
If one interface operates in full-power mode while another is in sleep mode to handle different data loads, then individual interface performance is optimized, but overall transmission efficiency deteriorates due to power mode mismatch
Solution Approach 1:
The control circuit acts as an intermediary between multiple high-speed data transmission interfaces, coordinating their power state transitions. It mediates between the conflicting requirements of individual interface performance optimization and system-wide transmission efficiency, ensuring that interfaces operate in synchronized power modes that maintain reliable data transmission while optimizing overall system performance.

AI summary
A data-transmission-format conversion circuit has a first data transmission interface, a second data transmission interface, and a control circuit. The control circuit is coupled to the first data transmission interface and the second data transmission interface for processing data-format conversions between the first data transmission interface and the second data transmission interface. The control circuit is further used to control the second data transmission interface to switch from a first corresponding power mode to a second corresponding power mode when the first data transmission interface is switched from a first power mode to a second power mode. The control circuit is further used to control the second data transmission interface to switch from the first corresponding power mode to a third corresponding power mode when the first data transmission interface is switched from the first power mode to a third power mode.
