Solution Overview

Problem

The transfer of large content files, such as complex video games and high-resolution movies, across networks is time-consuming and bandwidth-intensive, causing user frustration due to the significant size of these files and the associated delays.

Innovation Solution

A managed wireless distribution network is established where multiple devices communicate via multiple wireless networks, allowing portions of protected content to be transferred among devices, with each device hosting and consuming content only if the user has permission, thereby reducing reliance on internet data usage and speeding up content retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If content is transferred via traditional network, then content can be distributed, but transfer time is excessive and bandwidth is consumed

Engineering Contradiction:
Improvecontent transfer speedVSAvoidcontent retrieval time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The content is divided into multiple portions that can be distributed across different devices in the wireless network. Each device stores segments of the content locally, allowing parallel retrieval and reconstruction, thereby significantly reducing content retrieval time and improving transfer speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Content portions are pre-distributed and cached on multiple devices within the wireless network before actual content retrieval is needed. This preliminary distribution enables instant access when content is requested, eliminating traditional network transfer delays and significantly reducing retrieval time.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If content is cached on multiple devices, then content retrieval speed improves, but network security and permission management complexity increases

Engineering Contradiction:
Improvecontent distribution efficiencyVSAvoidpermission management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements a permission management mechanism that tracks and controls which devices can access which content portions. When content is requested, the system verifies device permissions and controls the reconstruction process accordingly, ensuring secure distribution while maintaining efficient content delivery through automated permission checking and content routing.

Inventive Principle:
Principle #23Feedback

3Speed

If wireless networks are used for content transfer, then transfer speed increases, but reliance on internet data caps and bandwidth limitations persists

Engineering Contradiction:
Improvewireless transfer speedVSAvoiddata usage volume
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The wireless network system enables devices to exchange content portions locally without requiring external internet connectivity. Devices serve themselves by retrieving cached content from neighboring devices in the wireless network, completely eliminating dependence on internet data caps and external bandwidth limitations while maintaining high transfer speeds through direct wireless communication.

Inventive Principle:
Principle #25Self-service

AI summary

Multiple portions of protected content to host on a device are identified by the device, the multiple portions including one or more portions of each of one or more pieces of protected content. The multiple portions are obtained and stored on the device. The device is one of multiple devices in a managed wireless distribution network that allows portions of protected content to be transferred among the multiple devices via multiple wireless networks hosted by various ones of the multiple devices, and the device is configured to store portions of protected content that can be consumed by a user of the device only if the user of the device has permission to consume the protected content. Participation of the device in the managed wireless distribution network can also be identified, and a reward generated based on the participation of the device in the managed wireless distribution network.
