Solution Overview

Problem

Existing data transmission devices require longer runtime to transmit large data files to external devices, as they typically use a single communication session, which limits efficiency.

Innovation Solution

A data transmission device capable of establishing multiple communication sessions concurrently, allowing data files to be divided and transmitted in portions across these sessions, thereby reducing transmission time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a single communication session is used to transmit data files, then the transmission process is simple and reliable, but the transmission runtime becomes excessively long for large data files

Engineering Contradiction:

Improvetransmission runtimeVSAvoidcommunication session management

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent divides a large data file into multiple data blocks and transmits them concurrently through multiple communication sessions. This segmentation allows parallel transmission, significantly reducing the total transmission runtime while managing complexity through systematic block division and session assignment

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple communication sessions are established concurrently, then data transmission speed increases, but the device complexity and session management overhead increase

Engineering Contradiction:

Improvedata transmission speedVSAvoidsession establishment and management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by pre-dividing the data file into blocks and pre-establishing multiple communication sessions before actual data transmission begins. This preparation work is done in advance, allowing the transmission phase to proceed efficiently without real-time decision-making complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms to monitor the status of multiple communication sessions and dynamically adjust transmission based on session performance, acknowledgments, and error conditions. This feedback system maintains reliability while managing the complexity of concurrent sessions

Inventive Principle:

Principle #23Feedback

3Loss of time

If data is transmitted serially through a single session, then the transmission process is simple to manage, but the runtime becomes unacceptably long for large files

Engineering Contradiction:

Improvetransmission runtimeVSAvoidtransmission process simplicity

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent transitions from single-dimensional serial transmission to multi-dimensional parallel transmission by utilizing multiple communication sessions simultaneously. This dimensional change from sequential to concurrent processing dramatically reduces transmission runtime while maintaining operational simplicity through automated session management

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
