Innovation Solution

A computer system that utilizes a prediction model to generate change policy data by altering feature values based on a feature profiling database, calculates evaluation values for these policies, and presents them as actionable information for achieving specific objectives related to the object, leveraging AI prediction results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If AI prediction is utilized to generate change policy data by altering feature values, then actionable information for improving KPIs is provided, but system complexity increases

Engineering Contradiction:
Improveactionable informationVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system segments the complex task of generating actionable insights into distinct functional modules: a prediction model processing unit that handles AI predictions, a change policy generation unit that creates alternative scenarios, and an evaluation unit that assesses effectiveness. This modular segmentation reduces overall system complexity while preserving the ability to generate actionable information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a feature profiling database as an intermediary component that stores pre-defined change rules and relationships between feature values. This intermediary structure simplifies the generation of change policy data by providing a standardized framework for altering feature values, reducing the complexity of directly manipulating raw prediction data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If change policy data is generated by changing multiple feature values based on feature profiling database, then comprehensive evaluation of actionable strategies is achieved, but calculation time increases

Engineering Contradiction:
Improvecomprehensive evaluationVSAvoidcalculation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-defining change rules and relationships between feature values in the feature profiling database before actual prediction analysis. This pre-processing establishes a framework of valid feature transformations, allowing the system to quickly generate change policy data without performing complex calculations during the actual evaluation phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent systematically varies parameter values (feature values) according to pre-defined change rules in the feature profiling database. By changing parameters in structured ways rather than exhaustive searches, the system achieves comprehensive evaluation of actionable strategies while controlling calculation time through efficient parameter sampling.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If AI prediction model is used to evaluate change policy data, then accuracy of KPI improvement prediction is improved, but computational resources increase

Engineering Contradiction:
Improveprediction accuracyVSAvoidcomputational resources
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by evaluating only the most promising change policy data generated from the feature profiling database, rather than exhaustively analyzing all possible feature value combinations. The prediction model focuses computational resources on assessing a selective subset of high-potential strategies, maintaining prediction accuracy while reducing overall computational resource consumption.

Inventive Principle:
Principle #16Partial or excessive action
