Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless packet data service networks face challenges in efficiently transmitting large message attachments from computers to mobile communication devices, as they often rely on low-bandwidth data paths, which can lead to slow and inconvenient attachment delivery.

Innovation Solution

The method involves using a second wireless data path with higher bandwidth than the primary path, potentially employing alternate radio access technologies or higher Quality of Service (QoS), to securely transmit message attachments directly to mobile communication devices, bypassing or supplementing the standard data paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If message attachments are transmitted via the primary wireless data path, then the messaging system maintains simplicity and security, but the transmission speed and bandwidth are insufficient for large attachments

Engineering Contradiction:

Improveattachment transmission speedVSAvoiddata path configuration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the data transmission by separating the messaging control path from the attachment data path. The primary wireless data path handles messaging while the secondary wireless data path handles attachment transmission, allowing each path to be optimized for its specific function and resolving the bandwidth limitation without compromising overall system simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a secondary wireless data path as an intermediary channel specifically for attachment transmission. This intermediary path with higher bandwidth capabilities enables fast attachment delivery while the primary path continues to handle messaging, thus improving productivity without significantly increasing device complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If a higher bandwidth data path is used for attachment transmission, then the delivery speed improves, but the system requires additional data path configuration and management

Engineering Contradiction:

Improveattachment delivery speedVSAvoiddual data path management

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent implements dynamic data path selection where the system automatically establishes a secondary wireless data path with higher bandwidth when attachment transmission is needed, and transitions back to the primary path for messaging. This dynamic adaptation allows high-speed attachment delivery without permanently increasing system complexity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary detection to identify when an attachment needs to be transmitted, then proactively establishes the secondary high-bandwidth data path before the actual attachment transfer begins. This preliminary action ensures optimal delivery speed while managing the complexity of dual path configuration through automated timing

Inventive Principle:
