Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
BLUETOOTH® enabled devices experience untimely energy consumption leading to battery drain and potential system failure due to continuous power supply demands without adequate relaxation time, particularly in low energy systems.
Innovation Solution
Implementing a non-conforming communication method that includes advertising availability, responding to scan requests, establishing connections, monitoring power consumption, and introducing a delay period for responses based on predefined criteria to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous power supply is provided to maintain BLUETOOTH® communication, then communication reliability is improved, but battery life deteriorates due to untimely energy consumption
Solution Approach 1:
The patent implements periodic connection events where the peripheral device wakes from sleep mode at predetermined intervals to communicate with the central device, then returns to sleep mode. This periodic action pattern allows the device to maintain communication capability while conserving battery energy during idle periods, directly resolving the contradiction between communication reliability and battery life.
Solution Approach 2:
The patent dynamically adjusts the device's operational state between active communication mode and sleep mode based on communication requirements. The peripheral device transitions between these states adaptively, being active only when connection events occur and remaining in sleep mode otherwise, thereby optimizing the balance between maintaining communication reliability and preserving battery life.
2Speed
If continuous communication events are processed, then communication responsiveness is improved, but power consumption increases causing battery crash
Solution Approach 1:
The patent establishes periodic connection events with predetermined intervals, where the peripheral device processes communication only at these scheduled times. This periodic processing approach ensures that the device remains responsive to communication needs while avoiding continuous power consumption, thereby managing the trade-off between communication responsiveness and power usage.
Solution Approach 2:
The patent maintains continuous communication capability through scheduled connection events, ensuring that the device is always available for communication when needed while minimizing idle power consumption. The continuous useful action is achieved by having the device wake periodically to handle communication tasks, rather than remaining continuously active or completely inactive.
3Productivity
If peripheral device responds immediately to connection events, then communication efficiency is improved, but battery relaxation time is reduced
Solution Approach 1:
The patent implements periodic connection events with predetermined intervals, where the peripheral device responds to communication at scheduled times rather than continuously. This periodic response mechanism maintains communication efficiency by ensuring timely responses at connection events while providing battery relaxation time during the intervals between events, thus resolving the contradiction between productivity and time loss.

AI summary
A computer implemented method for conserving power during BLUETOOTH® communication performed by a BLUETOOTH® enabled peripheral computing device, the method comprising advertising availability of the BLUETOOTH® enabled peripheral computing device for pairing, receiving a scan request from a BLUETOOTH® enabled central computing device. transmitting a scan response to the BLUETOOTH® enabled central computing device in response to the scan request, establishing a connection with the BLUETOOTH® enabled central computing device, monitoring a power consumption indicator of the peripheral computing device, introducing a delay period to a response period to a connection event received from the central computing device if the monitored power consumption indicator meets at least one predefined criteria, and wherein the delayed response period causes the response to occur after a predetermined peripheral latency period but prior to a supervision timeout.
