Solution Overview

Problem

Existing online shopping systems fail to accurately predict purchaser behavior, as they rely on outdated shopping funnel models that do not account for increased user activity levels and last-minute exploration, leading to potential purchases on competitor sites.

Innovation Solution

Implementing a purchase activity detection engine that monitors user activity patterns across sessions to provide personalized marketing and content, such as item suggestions and timely promotions, to increase the likelihood of a purchase on the ecommerce platform.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional shopping funnel models are used to predict purchaser behavior, then the system structure is simple, but the prediction accuracy deteriorates due to failure to account for increased user activity levels and last-minute exploration

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the shopping process into distinct stages (awareness, consideration, decision, post-purchase) and analyzes user activity patterns at each stage separately. This allows the system to capture nuanced behavioral changes at different funnel stages while maintaining manageable analysis complexity through staged processing of user interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts its analysis based on real-time user activity levels and behavioral patterns. It monitors changes in activity intensity, session duration, and interaction frequency to adapt predictions as users progress through the funnel or exhibit last-minute exploration behaviors, rather than relying on static historical averages.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If user activity monitoring is implemented across multiple sessions, then the understanding of consumer behavior improves, but the data processing requirements and computational resources increase

Engineering Contradiction:
Improvebehavioral insight completenessVSAvoidcomputational resource consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system extracts only the most relevant activity indicators from comprehensive user data, such as session duration, number of items viewed, search frequency, and cart modifications. By focusing on key behavioral signals rather than processing every user interaction in detail, the system maintains complete behavioral insights while reducing computational overhead.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system pre-processes and stores aggregated user activity metrics during and between sessions, preparing behavioral data in advance for faster analysis. This preliminary aggregation of user interactions into meaningful patterns reduces the computational burden during real-time prediction and decision-making moments.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If personalized marketing and content are provided based on activity patterns, then the probability of purchase increases, but the complexity of content delivery and personalization logic increases

Engineering Contradiction:
Improvepurchase conversion rateVSAvoidpersonalization system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system applies different personalization strategies tailored to specific user segments and funnel stages. For example, users in the awareness stage receive different content recommendations compared to those in the decision stage, and users exhibiting last-minute exploration behaviors receive targeted interventions. This localized approach increases conversion effectiveness while managing complexity through context-specific rules rather than universal complexity.

Inventive Principle:
Principle #3Local quality

AI summary

A user activity detection engine monitors user activity during user sessions on a publication system, and detects a change in the level of the activity of the user that predicts that the user is about to execute a transaction. The change may be an increase in the level of activity. When the user activity detection engine detects such a change, the system may make an intervention to provide personalized marketing content for display to the user in an effort to improve the probability that the user will execute a transaction, and/or also to motive the user to execute the transaction on the system site instead of moving to a competitor site in search of a different transaction.
