Solution Overview

Problem

Users face inefficiencies in accessing content across multiple applications on client devices, leading to missed engaging content due to irrelevant or infrequently updated applications, resulting in increased time spent navigating through various apps.

Innovation Solution

A content stream aggregates content items from various applications based on common topics, using metadata and user interaction data to identify and prioritize content items, presenting them in a personalized and visually appealing manner through a scrollable interface, allowing users to easily navigate and interact with relevant content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users access content through multiple separate applications, then they can access diverse content sources, but the time required to navigate and find engaging content increases significantly

Engineering Contradiction:

Improvecontent source diversityVSAvoidcontent navigation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines content from multiple separate applications into a single unified content stream interface. The system aggregates content items from different applications (news, social media, entertainment) and presents them together in one chronological feed, eliminating the need for users to switch between applications while maintaining access to diverse content sources.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The content stream serves multiple functions simultaneously: it acts as a news feed, social media aggregator, and entertainment portal all in one interface. The system provides universal access to various content types from different applications through a single unified interface, reducing navigation time while preserving content diversity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If applications provide frequent content updates, then users have more content to choose from, but the relevance and quality of content may decrease due to irrelevant items

Engineering Contradiction:

Improvecontent update frequencyVSAvoidcontent relevance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system applies different quality criteria and filtering rules to content from different applications based on their characteristics. Each content item is evaluated individually with application-specific relevance thresholds, ensuring that high-quality relevant content is prioritized while maintaining appropriate update frequencies from various sources.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts content selection parameters such as relevance thresholds, update frequencies, and quality scores based on user behavior patterns and content characteristics. This allows the system to optimize the balance between content volume and relevance by changing parameters like minimum engagement scores and time-weighting factors.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the content stream presents highly curated relevant content, then content quality improves, but the system complexity increases due to multiple evaluation criteria

Engineering Contradiction:

Improvecontent qualityVSAvoidevaluation system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically performs content evaluation, scoring, and filtering without requiring manual curation. Multiple quality metrics (relevance scores, engagement predictions, recency weights) are computed automatically for each content item, and the system self-adjusts based on user interactions, reducing the apparent complexity while maintaining high content quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces intermediary components such as quality score calculators, relevance filters, and ranking algorithms that mediate between raw content from applications and the final presented stream. These intermediary layers simplify the overall system architecture by breaking down complex evaluation into manageable modular components that can be independently optimized.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A content stream including content items retrieved from various applications executing on a client device is presented by the client device. A set of content items associated with a topic matching a stream topic associated with the content stream is identified from the retrieved content items. Quality scores are determined for each content item in the set providing a measure of a user's interest in each content item. A display set of content items is selected based on the quality scores, with one or more content items from the display set displayed based on a stream template. The stream template includes multiple slots each associated with one or more content items, and specifies a relative position of different slots to each other.
