Solution Overview

Problem

In P2P networks, mobile terminals face reduced working efficiency due to limited resources, as data uploading consumes excessive electrical and network resources, leading to potential crashes.

Innovation Solution

An asymmetric P2P network system where mobile terminals are prohibited from uploading data, allowing only computer terminals to provide uploading functions, ensuring mobile terminals can download resources from data servers or computer terminals without uploading, thus conserving resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile terminals perform P2P uploading and downloading, then network resource sharing is improved, but electricity consumption and network resource consumption increase, leading to reduced working efficiency and potential crashes

Engineering Contradiction:

Improvenetwork resource sharingVSAvoidelectricity consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements an asymmetric P2P network where mobile terminals are restricted to downloading only, while computer terminals handle both uploading and downloading. This asymmetric role assignment resolves the contradiction by preventing mobile terminals from consuming excessive electricity during uploading, while still enabling network resource sharing through computer terminal uploads.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

Different terminal types are assigned different functional qualities based on their local characteristics. Mobile terminals (with limited battery and resources) are given download-only capability, while computer terminals (with abundant resources) are given full upload/download capability. This local quality differentiation optimizes overall system performance.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If mobile terminals perform P2P uploading and downloading, then network resource sharing is improved, but network resource consumption increases, leading to reduced working efficiency and potential crashes

Engineering Contradiction:

Improvenetwork resource sharingVSAvoidnetwork resource consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The asymmetric network design restricts mobile terminals to downloading only, preventing them from consuming network resources during uploading. Computer terminals assume the uploading burden, optimizing overall network resource utilization while protecting mobile terminal efficiency.

Inventive Principle:

Principle #4Asymmetry

3Device complexity

If a centralized server is used for data distribution, then data transmission is simplified, but bandwidth is shared by multiple clients, resulting in incomplete bandwidth utilization

Engineering Contradiction:

Improvedata transmission structureVSAvoidbandwidth utilization

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments the centralized server model into a hybrid architecture with data servers for storage and multiple computer terminals as upload sources. This segmentation allows parallel data distribution from multiple sources, improving bandwidth utilization while maintaining manageable system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges centralized server storage with distributed P2P uploading capabilities. Data servers store original files while computer terminals provide distributed upload services, combining the advantages of both centralized and decentralized approaches to optimize bandwidth utilization.

Inventive Principle:

Principle #5Merging (Combining)

4Productivity

If computer terminals provide uploading functions in P2P network, then mobile terminals can download resources efficiently, but the system requires asymmetric role assignment that increases network complexity

Engineering Contradiction:

Improvedownload efficiencyVSAvoidnetwork structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The asymmetric role assignment between computer terminals (upload+download) and mobile terminals (download only) is implemented through standardized protocol extensions rather than complex network restructuring. The asymmetry is managed at the application layer, keeping network structure relatively simple while achieving high download efficiency.

Inventive Principle:

Principle #4Asymmetry
