Solution Overview

Problem

Existing digital services for debt management are one-dimensional, often recommending only one type of product and failing to consider individual needs and constraints, leading to suboptimal debt management strategies.

Innovation Solution

The development of optimized debt service strategy solutions utilizing products across multiple categories, leveraging trained surrogate models to estimate parameters and an optimizer model to determine the most effective strategy adhering to user-defined constraints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing digital services recommend only one type of product for debt management, then the service complexity is reduced and ease of operation is improved, but the adaptability to individual financial situations deteriorates and the quality of debt management advice worsens

Engineering Contradiction:
Improveease of operationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments the debt management solution into multiple product categories (balance transfer cards, personal loans, credit card consolidation, student loan refinancing) rather than recommending a single product type. This segmentation allows the system to evaluate different product types independently and select the most appropriate category based on individual user circumstances, thereby improving adaptability while maintaining operational simplicity through automated comparison and recommendation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements multi-functionality by creating a unified debt management platform that evaluates and recommends across multiple product categories simultaneously. The optimizer model serves multiple functions: it assesses user financial situations, compares various debt relief products, considers user constraints (monthly budget, credit score, debt amount), and generates personalized recommendations. This universal approach enables a single service to adapt to diverse individual needs across different debt scenarios.

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

2Device complexity

If existing digital services analyze only base level financial information, then the data processing complexity is reduced, but the measurement precision of individual financial situations deteriorates

Engineering Contradiction:
Improvedata processing complexityVSAvoidmeasurement precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by collecting and organizing comprehensive user financial information before generating recommendations. It gathers detailed data including monthly budget constraints, credit score, existing debt amounts, interest rates, and payment histories. This preliminary data collection and structuring enables subsequent precise analysis without requiring complex real-time processing during the recommendation phase, thus balancing measurement precision with manageable data processing complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an optimizer model as an intermediary between raw user financial data and recommendation outputs. This intermediary component processes comprehensive user information (including constrained monthly budget, credit score, debt characteristics) and translates it into evaluated debt service strategies. The optimizer model acts as a mediator that handles the complexity of analyzing multiple financial parameters simultaneously, enabling precise measurement of individual financial situations while keeping the overall system architecture manageable through modular processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If existing services fail to consider user constraints such as monthly budget, then the service operation is simplified, but the reliability of debt management advice deteriorates

Engineering Contradiction:
Improveservice operation simplicityVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system applies local quality by incorporating specific user constraints (monthly budget, credit score requirements, debt amount thresholds) into the recommendation process for each individual user. Rather than applying a uniform recommendation approach, the optimizer model evaluates user-specific constraints and tailors the debt management advice accordingly. This ensures that recommendations are locally optimized for each user's financial situation, improving reliability while maintaining operational simplicity through automated constraint-based filtering and selection.

Inventive Principle:
Principle #3Local quality
