Server Priority Control for Wireless Endoscope Communication Congestion

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In client-server systems with wireless endoscopes, communication traffic congestion leads to decreased communication speeds and increased power consumption due to multiple examination-and-treatment devices competing for a limited communication band, causing data transmission to be incomplete and prolonged.

Innovation Solution

A server and client system that determine the priority of connected devices and adjust data transmission based on access point information, instructing lower-priority devices to standby or change access points, thereby optimizing communication bandwidth and reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple examination-and-treatment devices freely perform data communication, then communication freedom is improved, but communication traffic increases and communication speed decreases

Engineering Contradiction:

Improvecommunication freedomVSAvoidcommunication speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The server dynamically changes communication parameters by assigning different priorities to different clients based on their communication requests. High-priority clients receive preferential treatment in bandwidth allocation, while low-priority clients are restricted or redirected to standby mode, thereby optimizing communication speed for critical devices while maintaining system flexibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The server acts as an intermediary between multiple examination-and-treatment devices and the network infrastructure. It mediates communication by receiving connection requests, determining priorities, and controlling data transmission accordingly, preventing direct uncontrolled access that would cause traffic congestion

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple examination-and-treatment devices freely perform data communication, then communication freedom is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication freedomVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The server dynamically adjusts communication parameters including priority levels and transmission permissions. Low-priority devices are instructed to enter standby mode or stop transmission, directly reducing their power consumption while high-priority devices maintain normal operation, achieving energy optimization without sacrificing communication flexibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The server implements periodic priority reevaluation and dynamic adjustment of communication permissions. Devices can transition between active and standby states based on changing priorities, creating a periodic pattern of communication activity that reduces overall power consumption while maintaining readiness when needed

Inventive Principle:

Principle #19Periodic action

3Reliability

If data transmission continues without priority management, then communication completeness is maintained, but transmission time increases

Engineering Contradiction:

Improvecommunication completenessVSAvoidtransmission time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The server changes the parameter of transmission permission based on priority levels. High-priority clients receive immediate transmission permission ensuring their data is transmitted quickly and completely, while low-priority clients are delayed or restricted. This differential parameter assignment reduces overall transmission time for critical data while maintaining completeness through structured priority-based scheduling

Inventive Principle:

Principle #35Parameter changes

AI summary

A server has a communicator, a decision unit, and a communication control unit. In a case in which a first condition and a second condition are satisfied, the decision unit decides to cause a first client to stop data transmission. In a case in which the first condition and a third condition are satisfied, the decision unit decides to cause a second client to stand by for the data transmission. The first condition indicates that an access point to which the first client is being connected is the same as an access point to which the second client is being connected. The second condition indicates that a priority of the first client is lower than a priority of the second client. The third condition indicates that priority information has not been received from the second client.
