Solution Overview

Problem

In information transfer systems, users face difficulties in recognizing data updates from a server, leading to unnecessary data transfers between the information transfer apparatus and the information presentation apparatus, which can result in wasteful data transfer and inability to operate the presentation apparatus.

Innovation Solution

An information transfer apparatus with a network interface connected to a server and a USB interface connected to an information presentation apparatus, featuring a switch and a control section that judges data updates, enabling connection only when data is updated and disabling it after transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If data transfer is performed frequently to ensure updated data is transferred, then data freshness is improved, but unnecessary data transfers increase causing operational disruption

Engineering Contradiction:

Improvedata freshnessVSAvoidapparatus operability

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system performs preliminary actions by enabling connection in advance before data transfer is actually needed. The control section enables connection between the information transfer apparatus and information presentation apparatus before initiating data transfer, ensuring that when data needs to be transferred, the connection is already established and ready, thus avoiding operational disruption while maintaining data freshness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the control section monitors whether data transfer is actually needed by checking if data has been updated on the server. Connection is enabled based on this feedback - only when updated data is detected. This prevents unnecessary connection enabling and maintains apparatus operability while ensuring data freshness when needed.

Inventive Principle:

Principle #23Feedback

2Speed

If connection is kept enabled to allow immediate data transfer, then transfer speed is improved, but the information presentation apparatus cannot be operated during connection

Engineering Contradiction:

Improvedata transfer speedVSAvoidapparatus operability

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The system dynamically adjusts the connection state based on actual data transfer needs. The control section enables connection only when updated data is detected and disables it after transfer completes. This dynamic connection management allows high transfer speed when needed while maintaining apparatus operability during non-transfer periods, resolving the contradiction between transfer speed and operability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs periodic action by enabling connection in discrete periods only when data transfer is actually required, rather than maintaining continuous connection. The control section periodically checks for data updates and enables connection temporarily during these periods. This periodic connection approach ensures fast transfer when needed while allowing normal operation during intervals between transfer periods.

Inventive Principle:

Principle #19Periodic action

3Productivity

If connection is enabled without checking data updates, then transfer readiness is improved, but wasteful data transfers occur consuming time and resources

Engineering Contradiction:

Improvetransfer readinessVSAvoidwasteful transfer time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The control section performs preliminary checking to determine whether data transfer is actually needed before enabling connection and initiating transfer. This preliminary check prevents wasteful data transfers by only enabling connection when updated data is detected, thus improving productivity without incurring time loss from unnecessary transfers.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from data update detection to control connection enabling. The control section receives feedback about whether data has been updated on the server and bases its connection enabling decision on this feedback. This ensures transfer readiness is maintained only when necessary, eliminating wasteful transfers while preserving productivity.

Inventive Principle:

Principle #23Feedback

AI summary

An information transfer apparatus of the present invention is an information transfer apparatus including a network interface connected to a server that distributes data, via a network, and a USB interface connected to an information presentation apparatus that presents the data, the information transfer apparatus transferring the data distributed from the server to the information presentation apparatus; and the information transfer apparatus includes: a switch that enables or disables connection with the information presentation apparatus via the USB interface; and a control section that judges whether or not the data distributed from the server has been updated, enables connection with the information presentation apparatus by the switch to transfer the data to the information presentation apparatus only upon judging that the data has been updated, and, after transferring the data, disables the connection with the information presentation apparatus by the switch.
