Solution Overview

Problem

Users of chat systems struggle with controlling the accessibility duration of content items or stories within the chat system, as existing technologies lack efficient mechanisms for managing the expiration or deletion of such content.

Innovation Solution

Implementing a timer-based system that allows users to set the duration for which content items remain accessible within the chat, with the option to suspend expiration by saving the content items, and enabling users to delete or unsave them from their personal storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If content items are automatically deleted after a set time in chat systems, then storage space is freed and privacy is protected, but users lose control over content accessibility duration

Engineering Contradiction:
Improveuser control over content accessibilityVSAvoidcontent management system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements dynamic content retention by allowing the deletion time period to be adjusted based on user actions. When a user saves a content item, the deletion timer is extended or suspended, making the system adaptive rather than static. This resolves the contradiction by providing user control (improving ease of operation) through a dynamic mechanism that automatically adjusts retention periods without requiring complex manual management (avoiding device complexity).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system automatically manages content deletion timelines without requiring user intervention. The server autonomously tracks deletion periods, extends them when content is saved, and executes deletions when appropriate. This self-service approach gives users control over content accessibility through simple save actions while the complex deletion management is handled automatically by the system, resolving the contradiction between user control and system complexity.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If users can save content items to extend accessibility, then user control and content preservation are improved, but system complexity increases

Engineering Contradiction:
Improvecontent accessibility controlVSAvoidtimer management system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The save function serves multiple purposes: it preserves content for the user, extends the deletion timeline, and potentially notifies other users in the chat. This multi-functionality increases adaptability without proportionally increasing complexity, as a single user action (saving) triggers multiple beneficial outcomes managed by the system.

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

Solution Approach 2:

The system provides feedback to users when content is saved, showing that the deletion period has been extended. This feedback mechanism helps users understand the system's response to their actions, making the extended functionality feel more intuitive and manageable, thereby improving adaptability while keeping the system appear simpler than it actually is.

Inventive Principle:
Principle #23Feedback

3Reliability

If automatic deletion is implemented in chat systems, then privacy and storage management are improved, but user experience suffers due to lack of control

Engineering Contradiction:
Improveprivacy protectionVSAvoidcontent management flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system pre-establishes deletion timelines when content is posted to the chat, automatically scheduling when content should be removed. This preliminary action ensures privacy protection is built-in from the start. Users can then save content to extend these pre-set timelines, gaining control without compromising the underlying privacy-focused automatic deletion mechanism.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The deletion timeline transitions from a fixed predetermined period to a dynamic period that adjusts based on user save actions. This dynamic adjustment maintains privacy protection through automatic deletion while providing users with flexibility to preserve content when needed, resolving the contradiction between reliability (privacy) and ease of operation (control).

Inventive Principle:
Principle #15Dynamics

AI summary

Users of a chat system within an interactive platform can suspend the expiration of a plurality of content items. Example methods include generating a chat, the chat comprising an association between a first user account and a second user account, and receiving, from a first user system associated with the first user account, an indication of a plurality of content items and an indication of the chat. The method may further include sending, to a second user account, the plurality of content items and an indication of the chat, and receiving, from the second user account, an indication to save the plurality of content items within the chat. The method may further include setting a saved data field associated with the plurality of content items and the second user account, the saved data field indicating the plurality of content items do not expire within the chat.
