Solution Overview

Problem

Current web browser implementations using large language models (LLMs) face latency issues due to computational intensity and network congestion, leading to unreliable and cumbersome content summarization features.

Innovation Solution

Implement a system where client computing devices manage webpage supplements by interfacing with a server to identify and retrieve LLM-based supplements using probabilistic data structures and private relays for secure communication, minimizing latency and privacy concerns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If web browsers access LLMs to provide content summarization features, then user productivity and information extraction are improved, but latency and processing time increase due to computational intensity

Engineering Contradiction:
Improvecontent summarization efficiencyVSAvoidlatency
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system pre-processes and stores webpage content in a database before user requests. When a user accesses a webpage, the content is already prepared and can be quickly retrieved and processed by the LLM, eliminating the need for real-time processing of large text inputs and significantly reducing latency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the content processing workflow into distinct phases: webpage content is pre-extracted and stored separately from the LLM processing. The LLM receives pre-formatted, segmented content representations rather than raw webpage text, enabling faster processing while maintaining summarization quality.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If LLMs process lengthy webpage content to provide accurate summaries, then information extraction quality is improved, but network bandwidth consumption and processing power requirements increase

Engineering Contradiction:
Improveinformation extraction accuracyVSAvoiddata transmission volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system extracts and pre-processes only the essential content information from webpages and stores it in a compressed format. When a user requests summarization, the system transmits this pre-extracted content representation to the LLM rather than the full webpage text, reducing network bandwidth requirements while maintaining the accuracy needed for quality summaries.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Content preprocessing and compression are performed in advance during webpage loading, so that when summarization is needed, only the essential processed data needs to be transmitted to the LLM, significantly reducing the quantity of data sent over the network.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If web browsers implement LLM-based summarization features, then user time savings are improved, but system complexity and infrastructure requirements increase

Engineering Contradiction:
Improveuser reading timeVSAvoidsystem infrastructure complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary content management system that sits between the web browser and the LLM. This intermediary handles the complex tasks of content extraction, formatting, and optimization, allowing the LLM to focus solely on generating summaries without dealing with the complexity of raw webpage processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system automatically detects when a user visits a webpage and autonomously extracts, processes, and prepares content for potential summarization requests. This self-service content preparation eliminates the need for manual user input and reduces the operational complexity of using LLM-based summarization features.

Inventive Principle:
Principle #25Self-service
