Solution Overview

Problem

Current methods for predicting user churn in mobile applications are inadequate as they rely on broad user characteristics such as age and location, failing to accurately determine user engagement and loyalty based on actual interaction patterns.

Innovation Solution

A churn prediction model that utilizes both behavioral data and user characteristics to estimate the probability of user churn, allowing for real-time analysis and intervention by identifying sequential patterns in user interactions and sending targeted messages or promotions to influence user behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional churn prediction methods using broad user characteristics (age, sex, zip code) are used, then the implementation is simple, but the prediction accuracy is insufficient

Engineering Contradiction:
Improvechurn prediction accuracyVSAvoidmodel complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the user base into distinct groups (loyals, churners, and intermediates) based on their interaction patterns with the application. By dividing users into these segments and analyzing their specific behavioral sequences, the model achieves higher prediction accuracy without requiring excessive complexity, as each segment can be analyzed with targeted features rather than universal complex modeling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transforms the prediction approach by changing from static demographic parameters to dynamic behavioral parameters. Instead of relying on fixed characteristics like age and zip code, the model uses sequences of user interactions and engagement metrics that change over time, thereby improving accuracy while keeping the model structure manageable through focused parameter selection.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If detailed behavioral data and interaction patterns are analyzed, then churn prediction accuracy improves, but data processing complexity increases

Engineering Contradiction:
Improveuser engagement measurement accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts specific meaningful sequences from the overall behavioral data rather than analyzing all possible interactions. By identifying and focusing on key interaction patterns that are most indicative of churn risk, the model achieves high measurement precision while avoiding the complexity of processing every possible behavioral variable. Irrelevant or redundant data points are excluded from the analysis.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary classification of users into loyalty segments before detailed analysis. This preliminary action groups users with similar behavioral patterns together, allowing subsequent analysis to focus on segment-specific characteristics rather than individual variations across the entire user base, thereby reducing overall data processing complexity while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If real-time churn prediction and intervention is implemented, then user retention improves, but system resource consumption increases

Engineering Contradiction:
Improveuser retention rateVSAvoidcomputational resource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by focusing intervention efforts only on users identified as being at risk of churn, rather than applying resources to all users. By using the predictive model to identify specific target users who need retention efforts, the system achieves improved overall retention rates while consuming computational resources only where necessary, avoiding wasteful universal processing.

Inventive Principle:
Principle #16Partial or excessive action

4Measurement precision

If comprehensive user interaction sequences are tracked, then prediction model granularity improves, but information storage requirements increase

Engineering Contradiction:
Improvebehavioral pattern detection accuracyVSAvoiddata storage volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential interaction sequences needed for churn prediction rather than storing complete detailed logs of all user activities. By identifying and retaining only those behavioral patterns that are predictive of churn, the system achieves high granularity in pattern detection while minimizing data storage requirements by excluding redundant or non-predictive information.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A churn prediction model is presented that uses both behavioral data as well as user characteristics to predict whether a given user will churn (i.e., stop using) an application. Initially a training set of user interactions can be correlated to a churn probability value for various sequences of user activity. Then, as regards a real time user, user actions in navigating through the app may be recorded, and this information can be used, in addition to user characteristics, to predict the probability that this user will churn, thus implementing in a "nip churn in the bud" approach (or, the inverse, remain loyal and continue to use the app). In some embodiments, a partial set of user actions can be identified as subsequences of known churn sequences. To users performing those subsequences of activity, a real time message, offer or promotion may be sent so as to influence them not to churn.
