Communication Interface Power-Saving Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses with multiple interfaces face reduced power-saving effects when entering a power-saving state, as not all connected devices comply with power-saving functions, leading to inefficient power management.
Innovation Solution
A communication apparatus determines whether connected devices comply with power-saving functions for each interface and selects the appropriate interface to operate based on ambient environment conditions, ensuring that only compliant interfaces are used during power-saving operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If one communication interface is selectively operated to reduce power consumption, then power-saving effect is improved, but the power-saving effect is reduced when the counter apparatus does not comply with power-saving function
Solution Approach 1:
The communication apparatus performs preliminary determination of power-saving function compliance for each communication interface before selecting which interface to operate. By checking compliance status in advance (prior to making the selection), the system ensures that it only chooses interfaces that support power-saving functions, thereby guaranteeing that the power-saving effect will be achieved when the apparatus enters power-saving state.
Solution Approach 2:
The system changes the selection criterion from simple connection status to a composite parameter that includes both connection status and power-saving function compliance. This parameter change enables the system to differentiate between interfaces based on their ability to support power-saving operations, ensuring optimal power savings while maintaining reliable communication.
2Adaptability or versatility
If multiple communication interfaces are connected to handle diverse communication needs, then adaptability is improved, but power consumption increases
Solution Approach 1:
The system segments the communication interface selection process into distinct evaluation steps: first checking connection status, then determining power-saving function compliance, and finally selecting the appropriate interface. This segmentation allows the apparatus to maintain multiple interfaces for adaptability while systematically choosing the most power-efficient option for each specific communication scenario.
Solution Approach 2:
The communication apparatus autonomously determines compliance status and selects the appropriate interface without external intervention. By self-managing the interface selection based on compliance information, the system reduces power consumption while maintaining the adaptability to use different interfaces as needed, with the added benefit of not requiring complex external control mechanisms.

AI summary
A communication apparatus, which is capable of communicating with a first apparatus via a first communication interface and communicating with a second apparatus via a second communication interface, determines whether the first apparatus complies with a power-saving function of the first communication interface and selects, based on a result of the determination, a communication interface to be operated when the communication apparatus is set to be in a power-saving state from between the first communication interface and the second communication interface. Depending on an ambient environment, a communication interface to be operated during a power-saving operation is selected to increase a power-saving effect.
