Solution Overview

Problem

Communication terminals face challenges in disconnecting wireless links at intended timings due to differences between software and hardware platforms, leading to prolonged connection maintenance and interference with other devices.

Innovation Solution

The smart device transmits a disconnection request to the information processing apparatus, which writes a disconnection timer to initiate the disconnection process, ensuring timely termination of connections and allowing other devices to communicate without delay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the communication terminal uses standard OS functions to disconnect wireless links, then the disconnection process is simple to implement, but the connection cannot be terminated at the intended timing due to software-hardware platform differences

Engineering Contradiction:

Improveconnection maintenance periodVSAvoiddisconnection timing accuracy

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent introduces a message transmission mechanism as an intermediary between the communication terminal and information processing apparatus. The terminal sends a disconnect request message that triggers the apparatus to initiate disconnection, bypassing the unreliable standard OS functions. This intermediary message passing system ensures disconnection occurs at the intended timing regardless of platform differences.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of having the communication terminal directly disconnect the wireless link using standard OS functions, the patent inverts the approach by having the terminal send a request message to the information processing apparatus, which then performs the disconnection action. This inversion allows the terminal to control disconnection timing indirectly through message passing, overcoming the limitations of direct OS function calls.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If the wireless connection is maintained longer to ensure compatibility across different platforms, then system reliability is improved, but other devices are interfered with and cannot use the information processing apparatus

Engineering Contradiction:

Improveplatform compatibilityVSAvoiddevice utilization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The message transmission mechanism serves as an intermediary that enables precise control over connection duration. By passing disconnect request messages between the terminal and apparatus, the system can terminate connections at exact intended timings, allowing rapid reassignment to other devices. This maintains platform compatibility through standardized message protocols while improving overall device utilization efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic connection management where the disconnection timing is adaptively controlled based on message exchange rather than fixed platform-specific OS schedules. This dynamic approach allows the system to optimize connection duration for each interaction, ensuring compatibility while maximizing productivity by quickly making devices available to subsequent users.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the disconnection request is transmitted through standard OS procedures, then the implementation is straightforward, but the disconnection does not occur at the intended timing

Engineering Contradiction:

Improvedisconnection implementation simplicityVSAvoiddisconnection delay

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces complex platform-specific disconnection procedures with a simple message transmission intermediary. The terminal sends a standard disconnect request message through the communication interface, which is universally supported across platforms. This intermediary approach maintains ease of operation by using standardized message passing while eliminating disconnection delays caused by platform-specific OS procedure variations.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processing apparatus is configured to communicate with a communication terminal. The apparatus includes a receiver, circuitry, and a transmitter. The receiver receives, from the communication terminal, a transmission request that requests that the information processing apparatus transmit a disconnection request to the communication terminal. The disconnection request is a request for requesting disconnection of a communication between the information processing apparatus and the communication terminal. The circuitry issues, in response to receiving the transmission request, an instruction for transmission of the disconnection request to the communication terminal. The transmitter transmits the disconnection request to the communication terminal in accordance with the instruction. The transmitter disconnects the communication between the information processing apparatus and the communication terminal in response to receiving a reply to the disconnection request from the communication terminal.
