Engineering Contradiction Analysis
1Use of energy by stationary object
If the apparatus switches between buffers for sleep operation and buffers for normal operation, then power consumption is reduced in sleep mode, but packet reception may fail during mode switching
Solution Approach 1:
The invention applies preliminary action by checking whether packets are being received during the buffer switching process before completing the mode transition. The system performs a verification step to ensure packet reception continuity, and only completes the sleep mode transition if no packets are lost during switching. This preliminary check prevents packet loss while enabling power savings.
2Productivity
If a high-speed CPU and high-speed memory are used for normal operation, then network processing speed is improved, but power consumption increases
Solution Approach 1:
The invention segments the system into two distinct operational modes with different hardware configurations: normal operation mode using high-speed CPU and memory for fast network processing, and sleep operation mode using low-speed CPU and memory for minimal power consumption. The system can switch between these segmented modes based on operational requirements, achieving both high performance when needed and low power consumption during idle periods.
3Reliability
If the apparatus remains accessible from network in sleep mode, then network availability is improved, but power consumption increases
Solution Approach 1:
The invention applies dynamics by implementing a configurable sleep mode that can dynamically adjust its accessibility level. The system offers multiple sleep modes including a standard sleep mode with reduced power consumption and a deeper sleep mode with even lower power consumption but longer wake-up time. This dynamic configuration allows the system to balance network availability requirements against power consumption goals based on specific operational scenarios.
