Innovation Solution

Utilizing interactive videos as a carrier for interaction between strangers, allowing users to upload and share videos that carry diversified user information expressions, and enabling contact establishment prompts to facilitate social connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users need to be friends to communicate through social tools, then communication privacy and security are improved, but communication accessibility and social connection opportunities deteriorate

Engineering Contradiction:
Improvecommunication securityVSAvoidcommunication accessibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an interactive video as an intermediary carrier that mediates communication between strangers. The video serves as a medium that allows users to interact without requiring pre-existing friend relationships, thus maintaining security while enabling accessibility. The server acts as another intermediary that manages video distribution and user interactions without exposing direct personal information.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication process is segmented into distinct phases: video upload phase, video distribution phase, and interaction phase. Users first upload videos without needing friend connections, then the server distributes videos to potential interactors, and finally interactions occur through the video medium. This segmentation allows strangers to communicate while maintaining privacy boundaries.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If traditional social tools require friend relationships, then user privacy protection is improved, but social interaction diversity and information sharing efficiency deteriorate

Engineering Contradiction:
Improveprivacy protectionVSAvoidinformation sharing efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent uses video copies as the primary interaction medium. Users upload original videos, and the server creates and distributes copies to multiple users. This allows information sharing without exposing users' direct identities or requiring friend relationships, thus maintaining privacy while improving sharing efficiency. The video copy serves as a decoupled medium that separates information content from user identity.

Inventive Principle:
Principle #26Copying

3Device complexity

If strangers cannot communicate through existing social tools, then system complexity is reduced, but user social experience and interaction opportunities deteriorate

Engineering Contradiction:
Improvesystem complexityVSAvoidsocial interaction ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The interactive video serves multiple functions within a single unified system: it acts as a communication carrier, a privacy protection mechanism, an interaction medium, and a connection establishment tool. This multi-functionality allows strangers to communicate without requiring complex friend management systems, thus improving ease of operation while maintaining manageable system complexity.

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

AI summary

The present application provides an information interaction method and apparatus, and a storage medium. In the method, a server receives an interactive video uploaded by a first user terminal, and sends the interactive video to a second user terminal. That is, in the embodiments of the present application, the video is taken as a carrier of interaction between strangers, which can bear diversified user information expressions. Moreover, the server further receives processing information for the interactive video sent by the second user terminal and/or the first user terminal, and processes the interactive video according to the processing information. That is, based on the video, friendly video interaction between strangers is realized, and social experiences of strangers in social activities are improved.
