Solution Overview

Problem

Current methodologies for browser real user monitoring (BRUM) fail to account for the impact of browser extensions on performance metrics, leading to incomplete and inaccurate assessments of user experience due to overlooked resource consumption by these extensions.

Innovation Solution

Integrate browser extension impact analysis into BRUM by identifying active extensions, generating testing configurations, and conducting performance assessments in a sandbox environment to provide a comprehensive view of their impact on metrics like Core Web Vitals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If browser extensions are installed to enhance functionality and customization, then user experience and browser capabilities are improved, but system resource consumption (memory, CPU) increases and performance metrics are degraded

Engineering Contradiction:

Improvebrowser functionalityVSAvoidsystem resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the browser environment into controlled testing instances where extensions can be individually evaluated. By creating isolated testing environments, the system can assess each extension's resource consumption separately, allowing users to understand and manage the impact of individual extensions on overall system resources.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically changes testing parameters such as memory allocation, CPU usage thresholds, and network conditions to evaluate extension performance under various scenarios. This allows for comprehensive assessment of how extensions behave across different resource states and helps identify optimal configuration settings.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If browser extensions are installed to provide enhanced functionality, then user capabilities are improved, but accuracy of performance metrics is degraded due to overlooked resource consumption

Engineering Contradiction:

Improvebrowser functionalityVSAvoidperformance metric accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements feedback mechanisms that continuously monitor and report extension performance data back to users and developers. By providing real-time feedback on resource consumption and performance impact, the system enables informed decision-making about extension usage and facilitates continuous optimization of extension performance.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system introduces an intermediary layer between extensions and performance metrics collection. This intermediary component acts as a mediator that isolates extension impacts, allowing for accurate measurement of individual extension effects on performance metrics without the confounding influence of other extensions or browser processes.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If traditional BRUM methodologies are used to monitor user experience, then intrinsic web properties are assessed, but external factors such as browser extensions are overlooked leading to incomplete evaluations

Engineering Contradiction:

Improveweb performance assessmentVSAvoidexternal factor data

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent creates a universal monitoring framework that can assess both intrinsic web properties and external factors like browser extensions through a single integrated system. This multi-functional approach allows the same infrastructure to collect and analyze diverse data types, from core web vitals to extension-specific performance metrics, providing comprehensive evaluation capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system adds another dimension to performance monitoring by incorporating extension impact assessment alongside traditional web performance metrics. This dimensional expansion transforms the monitoring space from solely web-centric to include the broader browser ecosystem, enabling holistic performance evaluation that accounts for all significant影响因素.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
