Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in reducing power consumption during idle periods, as existing methods for disconnecting and reconnecting often result in delayed reconnection, leading to suspended operation states that hinder data communication when data is needed.
Innovation Solution
A wireless communication device system that shares re-connection information before disconnection, allowing for controlled power management and timely reconnection based on shared timing, ensuring connectivity when data is required while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication device continuously transmits or receives signals to maintain a link, then connection reliability is improved, but power consumption increases
Solution Approach 1:
The device performs preliminary actions by continuously transmitting or receiving signals during the connection period to maintain the link, and then suspends operations during the suspension period to save power. This alternating pattern ensures connection reliability when needed while reducing power consumption during idle times.
Solution Approach 2:
The wireless communication device operates in periodic cycles, alternating between connection periods (where signals are transmitted/received to maintain link reliability) and suspension periods (where operations are suspended to reduce power consumption). This periodic action resolves the contradiction by timing operations to match actual communication needs.
2Use of energy by moving object
If the wireless communication device suspends operations to save power, then power consumption is reduced, but connection establishment time increases when data needs to be transmitted
Solution Approach 1:
The device performs preliminary link maintenance actions during connection periods by continuously transmitting or receiving signals, ensuring the connection is ready for immediate data transmission. This preliminary action reduces the time needed to re-establish connections after suspension periods.
Solution Approach 2:
The wireless communication device dynamically adjusts its operation status between connection and suspension modes based on communication needs. The device transitions from a suspended state to an active connection state when data transmission is required, optimizing the balance between power consumption and connection establishment time.
3Use of energy by moving object
If the wireless communication device disconnects after a predetermined time in power saving mode, then power consumption is reduced, but data communication is delayed until reconnection completes
Solution Approach 1:
The device implements periodic action by alternating between connection periods (where the link is maintained and data communication can occur immediately) and suspension periods (where power is saved by suspending operations). This periodic pattern ensures that when the device wakes from suspension, it can quickly resume data communication without significant delays.
Solution Approach 2:
The wireless communication device dynamically transitions between operational states based on communication requirements. During connection periods, the device maintains the link for immediate data communication. When suspending operations to save power, the device is configured to quickly re-establish connections when data needs to be transmitted, minimizing productivity loss.

AI summary
A central transmits, to a peripheral connected with the central, re-connection information indicating a timing of a re-connection after a disconnection. Subsequently, the central executes a connection discontinuing process based on the re-connection information. In addition, the central controls power supply for wireless communication at a timing determined based on the re-connection information. Thereafter, the central executes a re-connection process with the peripheral based on the re-connection information shared therewith prior to the disconnection.
