Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If financial institutions use simple static statistic models and ad hoc data averaging to estimate interest rate impact, then the modeling process is straightforward to implement, but the estimation accuracy deteriorates and the process becomes time and labor intensive
Solution Approach 1:
The patent transitions from static statistic models to dynamic demand models that can adapt and update estimates in real-time. The system continuously processes transaction records and rate change data to provide current, accurate estimates of customer behavior responses to interest rate changes, eliminating the need for time-consuming manual model updates while maintaining high accuracy.
Solution Approach 2:
The patent replaces manual ad hoc data averaging processes with an automated computer-based system that uses sophisticated algorithms to analyze transaction records and calculate demand model estimates. This substitution eliminates labor-intensive manual calculations while significantly improving estimation accuracy through consistent, reproducible computational methods.
2Device complexity
If financial institutions use simple static statistic models for origination volume estimation, then the model complexity is low, but the estimation accuracy for other customer behaviors deteriorates
Solution Approach 1:
The patent divides the complex task of estimating all customer behaviors into separate, specialized demand models for each behavior type (origination, utilization, line increase, loan life adjustment, fixed-rate conversion). Each segmented model focuses on specific customer responses, allowing for higher accuracy in each area while maintaining manageable individual model complexities that can be processed automatically.
3Ease of manufacture
If financial institutions use ad hoc data averaging to obtain information on customer behaviors, then the data processing is simple, but the estimation accuracy deteriorates
Solution Approach 1:
The patent replaces simple ad hoc data averaging with sophisticated automated computational algorithms that process transaction records and rate change data. The system uses advanced statistical and machine learning methods to extract meaningful patterns and generate accurate estimates of customer behavior responses, achieving high precision through automated computation rather than manual averaging.
4Measurement precision
If financial institutions manually analyze multiple customer behaviors separately, then the analysis depth for each behavior can be thorough, but the overall productivity deteriorates
Solution Approach 1:
The patent merges multiple separate demand model analyses into a single integrated system that processes all customer behaviors (origination, utilization, line increase, loan life adjustment, fixed-rate conversion) simultaneously. The integrated system analyzes transaction records and rate changes across all behavior types in one unified computational framework, achieving both thorough analysis depth and high productivity through consolidation.
Solution Approach 2:
The patent creates a universal demand modeling system that handles multiple types of customer behaviors through a single platform. The system is designed to be multi-functional, capable of analyzing different behavior types using consistent methodologies and data sources, thereby improving overall productivity while maintaining comprehensive analysis depth for each behavior type.

AI summary
A computing system (100) receives transaction records (130) for loans taken at various interest rates (1904) for a loan segment (902). Performance indicators (1716) indicative of customer behaviors (1702) are computed (1806) using independent demand models (300, 302, 304, 306, and 308). Computing system (100) includes a performance indicator forecaster (112) that determines relationships between the performance indicators (1716) and various prices, or interest rates (1904). These relationships can include profit (1906) and/or volume (1908) relative to the various interest rates (1904). The relationships are utilized to select an interest rate (1912, 2102) for the product segment (902) for implementation by a financial institution.
