File Upload Address Management for Interrupted Transfer Resumption

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing techniques fail to store information about interrupted upload operations and restart them when the upload destination is changed during the process, leading to incomplete data transfers.

Innovation Solution

A communication apparatus with an acquisition unit to acquire transmission destination addresses, a management unit to manage these addresses for each connection destination, and a transmission unit to resume uploads from the point of interruption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the upload destination is changed during the upload operation, then the system can adapt to new storage locations, but the ability to store and resume interrupted upload operations is lost

Engineering Contradiction:

Improveupload destination change capabilityVSAvoidupload operation resumption

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the upload management system into distinct components: a management unit that handles connection destination information and a transmission unit that performs actual file transfers. This segmentation allows the management unit to maintain records of upload operations across different connection destinations, enabling resumption capability even when destinations change.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The management unit acts as an intermediary between the transmission unit and multiple connection destinations. It stores and manages transmission destination addresses, maintaining a record that allows the system to resume interrupted operations regardless of which connection destination is currently active, thus bridging the gap between adaptability and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system stores detailed upload information for each connection destination, then upload resumption is enabled, but the system complexity increases

Engineering Contradiction:

Improveupload operation resumptionVSAvoidmanagement system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The management unit is designed with multi-functionality, serving both to manage connection destination information and to enable upload resumption. This universal approach consolidates multiple functions into a single component, reducing overall system complexity while maintaining reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system manages connection destination information as changeable parameters (transmission destination addresses) that can be updated when upload destinations change. By treating this information as flexible parameters rather than fixed structures, the system maintains simplicity while adapting to different upload scenarios.

Inventive Principle:

Principle #35Parameter changes
