Engineering Contradiction Analysis
1Productivity
If the bridge module and data transceiver device operate at high power consumption levels, then data transmission speed and processing performance are improved, but the host cannot provide sufficient power energy leading to system damage
Solution Approach 1:
The patent implements dynamic power management by adjusting the operation mode of the bridge module and data transceiver device based on real-time power status signals from the host. The system transitions between different operational states (normal mode, power saving mode, suspend mode) to dynamically balance power consumption with data transmission requirements, preventing system damage while maintaining productivity within available power constraints.
Solution Approach 2:
The system changes operational parameters (clock frequency, data transmission rate, operation mode) based on the power status signal. When power is insufficient, the processing device reduces its clock frequency and the data transceiver device lowers its transmission rate, thereby adjusting power consumption to match the host's power supply capability while maintaining system operation.
2Productivity
If the processing device operates at high clock frequency, then data processing capability is improved, but power consumption increases beyond what the host can provide
Solution Approach 1:
The processing device dynamically adjusts its clock frequency based on power status signals from the host. In normal mode, it operates at full frequency for maximum processing capability. When power is limited, it transitions to power saving mode with reduced frequency, and to suspend mode with minimal frequency, thereby adapting processing capability to available power while preventing system damage.
Solution Approach 2:
The system employs feedback control where the host monitors power consumption and sends power status signals to the bridge module. The processing device receives these signals and adjusts its clock frequency accordingly, creating a closed-loop control system that continuously balances processing capability with power supply constraints.
3Productivity
If the data transceiver device operates at high transmission speed, then data exchange efficiency is improved, but total power consumption exceeds host supply capacity
Solution Approach 1:
The data transceiver device dynamically adjusts its data transmission rate based on power status signals. In normal mode, it operates at full transmission speed for maximum efficiency. When power is insufficient, it transitions to power saving mode with reduced transmission rate, and to suspend mode with minimal activity, thereby adapting transmission efficiency to available power while preventing system damage.
4Productivity
If the bridge module continuously operates at full power, then data exchange between host and data transceiver device is efficient, but the host power supply becomes insufficient causing unstable operations
Solution Approach 1:
The bridge module implements dynamic operation mode switching between normal mode, power saving mode, and suspend mode based on host power status. This dynamic adjustment ensures that the total power consumption of the bridge module and data transceiver device remains within the host's power supply capacity, maintaining system stability while optimizing data exchange efficiency within available power constraints.
Solution Approach 2:
The system uses feedback from host power status signals to continuously monitor and adjust power consumption. When the host detects insufficient power supply capability, it sends signals to the bridge module to transition to lower power modes, creating a self-regulating system that maintains reliability by preventing power overload conditions.
