Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-power electronic devices face challenges in optimizing energy consumption during short-range wireless communication, particularly in scenarios where unnecessary data packets are transmitted, leading to increased power consumption and reduced device performance.
Innovation Solution
The implementation of an operation method for electronic devices that determines whether to send a response signal based on valid data packet validation, data transmission requirements, and flush point conditions, allowing for the suppression of unnecessary ACK/NACK signals and optimizing energy usage by only transmitting necessary data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device transmits response signals (ACK/NACK) for every received data packet, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by transmitting response signals only when necessary rather than for every data packet. The controller determines whether to send ACK/NACK signals based on whether the received data packet is the last packet before a flush point and whether there is data to be transmitted, thus performing the response action only partially rather than continuously, reducing power consumption while maintaining communication reliability.
2Reliability
If the electronic device transmits data packets continuously, then data transmission completeness is improved, but unnecessary transmissions increase power consumption
Solution Approach 1:
The patent implements feedback mechanisms where the controller monitors multiple conditions including valid information indicating validation of the received data packet, data check information indicating whether there is data to be transmitted, and flush information indicating whether the current sub-event is the last sub-event before a flush point. Based on this feedback, the controller intelligently determines whether to send response signals, avoiding unnecessary transmissions and reducing energy consumption while ensuring complete data transmission.
3Reliability
If the electronic device sends response signals for all received packets, then communication protocol compliance is improved, but device performance deteriorates due to increased processing overhead
Solution Approach 1:
The patent applies partial action by selectively sending response signals only when protocol requirements are met and data transmission is necessary. The controller evaluates multiple conditions including validation status, data transmission needs, and flush point timing to determine partial compliance rather than unconditional response, thereby maintaining protocol compliance where needed while reducing processing overhead and improving device performance.

AI summary
Disclosed are operation methods of electronic devices that perform short-range wireless communication. The method includes receiving a data packet from an outside, determining whether to send a response signal, based on valid information indicating validation of the received data packet, data check information indicating whether there are data to be transmitted to the outside, and flush information indicating whether a current sub-event is a last sub-event just before a flush point for the received data packet, in response to the received data packet, and sending the response signal in consideration of a result of the determining whether to send the response signal.
