Solution Overview

Problem

Existing methods for recommending software applications on mobile devices are unreliable and often misleading, relying on external sources like reviews and pop-up ads.

Innovation Solution

A system for automatic software recommendations between mobile devices based on already installed apps, triggered by a file transfer selection, using a direct device-to-device connection to analyze and suggest compatible applications for transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users obtain app recommendations from external sources like reviews or pop-up ads, then they can access a wide range of app suggestions, but the reliability and trustworthiness of these recommendations deteriorates

Engineering Contradiction:
Improverecommendation trustworthinessVSAvoidrecommendation source diversity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a file transfer system as an intermediary mechanism that indirectly provides app recommendations. Instead of directly recommending apps through unreliable external sources, the system recommends apps based on file transfer scenarios, using the file transfer context as a mediator to establish trustworthy recommendations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables devices to automatically generate and exchange app recommendations based on their own installed applications and file transfer patterns. Each device serves itself by analyzing its own app ecosystem and transferring relevant recommendations to peer devices, eliminating dependence on external recommendation sources.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If the system analyzes installed apps to generate recommendations, then the relevance and personalization of suggestions improves, but the processing time and computational resources increase

Engineering Contradiction:
Improverecommendation relevanceVSAvoidanalysis processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of installed applications and their associations during normal device operation, building a knowledge base of app relationships and usage patterns in advance. This pre-processing enables rapid generation of relevant recommendations when file transfer scenarios occur, without requiring extensive real-time analysis.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the system uses direct device-to-device connection for recommendation transfer, then the reliability and security of transmission improves, but the complexity of establishing connection increases

Engineering Contradiction:
Improvetransmission securityVSAvoidconnection establishment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages existing file transfer protocols and communication channels that devices already support for other purposes. By making the recommendation system multi-functional—using the same infrastructure for both file transfer and app recommendations—the system achieves secure direct device-to-device communication without adding significant connection establishment complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A mobile computer system for a device-to-device content recommendation including a processor configured to execute computer-executable instructions for establishing a directed device-to-device connection between a source app of a first device and a destination app of a second device. The processor further receives a selection of one or more files to be transferred to the destination app via a graphical user interface. The processor further analyzes one or more of the following: the selected one or more files, and the apps already installed on the first device. The processor identifies a content to be recommended to the second device, wherein the identified content may be initially invisible to a user before the selection. In response to the identification and the selection, the processor locates data of the content in the first device and selects the content to be transferred along with the selection of the one or more files.
