Solution Overview

Problem

Conventional feature auditing is performed synchronously, limiting the ability to perform advanced analytics and temporal analysis of system features, as it lacks holistic information correlating performance across features.

Innovation Solution

Maintaining an asynchronous audit trail by recording metadata information about feature changes, including temporal identifiers, activation states, and performance metrics in a feature database, allowing for advanced analytics across the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If synchronous audit logging is used to record feature changes, then the audit log is maintained with simple sequential recording, but advanced analytics and temporal analysis cannot be performed due to lack of holistic information

Engineering Contradiction:
Improveholistic information for analyticsVSAvoidaudit trail structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the audit trail into multiple independent chains, each associated with a specific feature. Instead of a single sequential log, the system creates feature-specific audit chains that can be independently tracked and analyzed. This segmentation enables holistic information collection for analytics while maintaining manageable complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds temporal dimensionality to the audit trail by introducing temporal identifiers and establishing chronological relationships between feature changes. This transforms the flat sequential log into a multi-dimensional structure that incorporates time-based ordering, enabling temporal analysis and advanced analytics while organizing information in a structured manner.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If feature changes are logged synchronously at the time of change, then the logging process is simple and fast, but temporal analysis and correlation of performance across features are precluded

Engineering Contradiction:
Improvelogging speedVSAvoidtemporal analysis capability
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by establishing temporal identifiers and chronological ordering at the time of feature changes. Instead of waiting for analysis to occur, the system pre-structures the audit trail with time-based metadata and relationships, enabling future temporal analysis without sacrificing logging speed. This preliminary structuring allows both fast logging and subsequent temporal correlation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces temporal identifiers as intermediary elements that mediate between the synchronous logging process and temporal analysis requirements. These identifiers act as a bridge, capturing time-based information during fast synchronous logging while enabling subsequent temporal correlation and analysis without requiring slower processing speeds.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a conventional audit log records only single feature status, then the log structure is simple, but advanced analytics correlating performance across multiple features cannot be performed

Engineering Contradiction:
Improveanalytics capabilityVSAvoidperformance correlation data
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates a universal audit trail structure that serves multiple functions: it records individual feature changes, establishes temporal relationships, and enables cross-feature correlation analysis. This multi-functional design allows the same audit trail to support both simple feature tracking and advanced analytics, eliminating the need for separate logging mechanisms and preserving performance correlation data.

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

AI summary

Methods and systems for performing advanced analytics based on which features are active by correlating information based on temporal identifiers in feature databases. The method includes receiving a request to change a feature, determining metadata information for the feature, which may include a temporal indicator, a performance metric and a configuration of activation states, and generating a feature change record based on this metadata. The method includes receiving a request to determine a second performance metric, processing the request by determining a second feature change record, determining a configuration and generating a recommendation for display.
