Solution Overview

Problem

Existing web conference systems lack an efficient method for sharing printed information between participants, limiting collaboration and information dissemination.

Innovation Solution

A web conference system with a server system that includes an acceptance unit for participation requests, a transmission unit for voice data, and output units for sound and printer information, allowing participants to share printer connections and instruct printing via the server system, enabling seamless sharing of printed data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If printer information is shared between participants in a web conference, then information sharing capability is improved, but system complexity increases

Engineering Contradiction:
Improveinformation sharing capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The web conference server acts as an intermediary that mediates printer information sharing between participants. The server receives printer status information from one participant's apparatus and distributes it to other participants' apparatuses, enabling indirect information sharing without requiring direct peer-to-peer connections. This reduces system complexity by centralizing the coordination function in the existing server infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The web conference server is extended to perform multiple functions: it continues to provide voice and video conference services while also managing printer information distribution and print job coordination. By making the server universal and multi-functional, the system avoids adding separate dedicated infrastructure for printer sharing, thereby limiting the increase in overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If printing is enabled via web conference system, then ease of operation is improved, but security risks increase

Engineering Contradiction:
Improveprinting operation convenienceVSAvoiddata leakage risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback mechanisms where the server receives printer status information (connected/disconnected states) from participants' apparatuses and uses this feedback to control print job routing. Before enabling printing, the system checks the feedback information to verify printer availability and authorization status. This feedback loop ensures that printing operations only proceed when security conditions are met, preventing unauthorized data leakage while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary checks of printer connection status and authorization before allowing print operations. The server pre-validates whether a participant has authorized printers available and whether the print job should be routed to a specific participant's apparatus. By performing these security validations in advance rather than during the actual printing process, the system prevents potential data leakage while maintaining a simple user interface.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If real-time printer status information is transmitted to all participants, then information sharing is improved, but network bandwidth consumption increases

Engineering Contradiction:
Improveinformation availabilityVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system segments printer status information transmission by sending updates only to participants who have expressed interest in or need for the printed information, rather than broadcasting to all conference participants. The server divides the participant group into those who require printer status information and those who do not, transmitting segmented information streams accordingly. This reduces unnecessary network traffic while ensuring that relevant participants receive real-time updates.

Inventive Principle:
Principle #1Segmentation

AI summary

A web conference system is provided whereby a second apparatus transmits first information indicating whether a printer is connected to a second apparatus or second information indicating setting related to the printer connected to the second apparatus to a server. The server transmits the first information or the second information to a first apparatus. The first apparatus displays printer information about the printer connected to the second apparatus on a display screen based on the first information or the second information.
