Network Interface Power Mode Switching by Data Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses do not effectively consider the frequency of data reception for each data type when switching from a normal mode to an energy-saving mode, leading to inefficient power management.
Innovation Solution
An electronic apparatus with a network interface, communication processing unit, and operation mode control unit that switches from a normal mode to an energy-saving mode based on a waiting time determined by the network communication amount for each network communication type, allowing for dynamic adjustment of power consumption according to usage patterns.

Engineering Contradiction Analysis
1Use of energy by stationary object
If the waiting time until shifting to energy-saving mode is set based on operation type and execution frequency, then the power management can be optimized for different operation patterns, but the frequency with which data is received for each data type is not taken into consideration leading to suboptimal energy saving
Solution Approach 1:
The patent segments network communication data into different data types (e.g., print data, scan data, fax data) and establishes separate waiting time settings for each data type. The storage unit stores multiple waiting time values corresponding to different data types, and the control unit selectively applies the appropriate waiting time based on the received data type. This segmentation allows the system to optimize power management for each specific communication pattern while adapting to varying data reception frequencies.
2Device complexity
If a fixed waiting time is used for switching to energy-saving mode, then the control logic is simple, but it cannot adapt to different network communication patterns and data types leading to inefficient power consumption
Solution Approach 1:
The patent implements dynamic waiting time adjustment by storing multiple waiting time values in the storage unit, each corresponding to different data types or communication patterns. The control unit dynamically selects the appropriate waiting time based on the actual received data type, transforming the system from a static fixed-time approach to a dynamic adaptive approach. This allows the system to optimize power consumption by matching the waiting time to the specific communication pattern while maintaining manageable control logic through automated selection.
