Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a preset discarding pattern is used to reduce power consumption, then the frequency of returning to normal power mode is reduced, but the pattern cannot accurately adapt to varying network environments leading to insufficient power savings
Solution Approach 1:
The patent implements dynamic adaptation by allowing the information processing device to learn from actual network packet reception patterns and automatically update the discarding pattern accordingly. The system transitions from a static preset pattern to a dynamic pattern that adapts to the specific network environment, enabling accurate prediction of high-frequency packet types while maintaining power-saving mode effectiveness.
Solution Approach 2:
The patent incorporates feedback mechanisms where the device monitors actual network packet reception and uses this information to refine and update the discarding pattern. By continuously learning from real network traffic patterns, the system optimizes the discarding pattern to match the actual network environment, thereby extending power-saving mode duration without missing important packets.
2Use of energy by moving object
If the device operates in power-saving mode to reduce power consumption, then energy usage is reduced, but the device cannot process network packets requiring main control unit intervention
Solution Approach 1:
The patent applies preliminary action by pre-learning and storing the discarding pattern before the device enters power-saving mode. The system analyzes network packet characteristics in advance and creates a discrimination pattern that enables the communication unit to autonomously discard irrelevant packets without requiring main control unit intervention, thus maintaining productivity while saving power.
Solution Approach 2:
The patent introduces a discarding pattern as an intermediary between the communication unit and the main control unit. This pattern acts as a filtering mechanism that pre-processes incoming packets, allowing the communication unit to autonomously discard unnecessary packets and only forward relevant ones to the main control unit, thereby maintaining processing capability while extending power-saving mode operation.
3Use of energy by moving object
If a user manually analyzes and sets the discarding pattern to optimize power-saving mode, then power consumption can be sufficiently reduced, but the working burden on the user becomes excessive
Solution Approach 1:
The patent implements self-service by enabling the information processing device to automatically learn and update its own discarding pattern without user intervention. The system autonomously monitors network traffic, identifies high-frequency packet types, and dynamically adjusts the discarding pattern to optimize power-saving mode performance, completely eliminating the need for manual user analysis and configuration.

AI summary
A controller of an information processing device receives a packet via the network interface and performs a process corresponding to the received packet when the information processing device operates in the first power mode. The network interface performs a process of transmitting the received packet to the controller when the information processing device operates in the first power mode, and performs a process of discarding the received packet or the process of transmitting the received packet to the controller when the information processing device operates in the second power mode. The network interface has a storage area in which a discarding determination pattern is stored. The controller performs a process of updating a list of the discarding determination pattern to be stored in the network interface based on determination of whether a process on the received packet in the controller is a discarding process.
