Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The asynchronicity between the requirement for communication interface availability from sleep-clients and the actual availability of the wireless chip in sleep-mode leads to information loss and reduced efficiency in wireless communication devices.
Innovation Solution
A method and system that modify a memory location associated with the communication interface to advertise availability, allowing sleep-client devices to check and request the interface, and sending interrupt signals upon changes, ensuring data can be transmitted correctly when the chip is ready.

Engineering Contradiction Analysis
1Use of energy by moving object
If the wireless chip enters sleep-mode to save energy, then power consumption is reduced, but the communication interface becomes unavailable causing information loss
Solution Approach 1:
The system performs preliminary actions by setting the communication interface availability status in memory before the wireless chip enters sleep-mode. Sleep-clients can check this status in advance and delay their data transmission until the interface is available, preventing information loss while maintaining energy savings.
Solution Approach 2:
The system implements feedback mechanisms where the wireless chip periodically updates the communication interface availability status in memory. Sleep-clients continuously monitor this status and adjust their transmission timing accordingly, creating a closed-loop system that prevents data loss while maintaining sleep-mode operation.
2Reliability
If the wireless chip wakes-up periodically to sense the wireless medium, then communication capability is maintained, but energy savings are reduced
Solution Approach 1:
The system enables sleep-clients to autonomously check the communication interface availability status in memory and self-regulate their transmission timing. This eliminates the need for the wireless chip to wake-up frequently, as clients can independently determine when the interface is available, reducing energy consumption while maintaining communication reliability.
Solution Approach 2:
The wireless chip performs preliminary updates to the interface availability status before entering sleep-mode. This allows sleep-clients to plan their transmissions in advance without requiring the chip to be awake, reducing the frequency of wake-up cycles while ensuring communication capability is maintained.
3Ease of operation
If sleep-clients send wake-up signals to request interface availability, then data transmission can proceed, but system complexity increases
Solution Approach 1:
The system introduces an intermediary mechanism - a memory location storing the communication interface availability status - that mediates between the wireless chip and sleep-clients. This simple intermediary provides a clear interface for clients to check availability and coordinate transmissions, simplifying the overall interaction despite the added memory component.
