Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interest calculation methods based on end-of-day balances fail to accurately reflect rapid fluctuations in account balances due to real-time transactions, leading to potential losses in interest revenues for banks offering real-time services.
Innovation Solution
Implementing interest calculations using precise time parameters, such as seconds, to define valuation intervals and determine interest accruals or charges, allowing for more precise capture of balance fluctuations throughout the day.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If interest calculation is based on end-of-day balances, then calculation simplicity is maintained, but measurement precision of interest accruals deteriorates
Solution Approach 1:
The patent segments the continuous account balance into discrete valuation snapshots taken at specific intervals (e.g., every 15 minutes or at transaction times). Instead of using a single end-of-day balance, the system divides the day into multiple valuation periods, each with its own balance snapshot. This segmentation allows precise tracking of balance fluctuations while maintaining manageable calculation complexity through structured time-based division.
Solution Approach 2:
The system implements periodic valuation of account balances at predetermined intervals throughout the day (such as every 15 minutes or at specific transaction triggers). This periodic sampling approach captures balance fluctuations without requiring continuous monitoring, thereby achieving measurement precision through regular snapshots while avoiding the complexity of continuous real-time calculation systems.
2Adaptability or versatility
If real-time transaction services are offered, then service quality improves, but interest revenue loss increases
Solution Approach 1:
The system performs preliminary valuation of account balances at predetermined intervals before the actual transaction completes. By establishing valuation snapshots at specific times (e.g., every 15 minutes) or upon transaction initiation, the system proactively captures balance states that will be used for interest calculation, ensuring that real-time service capabilities are maintained while interest revenues are preserved through pre-established valuation points.
Solution Approach 2:
The system implements feedback mechanisms where transaction data is continuously fed back into the valuation process. Each transaction triggers a re-evaluation of the account balance at the next predetermined valuation interval, ensuring that interest calculations reflect the most recent balance state. This feedback loop allows real-time service adaptability while capturing interest revenues that would otherwise be lost in traditional end-of-day systems.
3Productivity
If valuation intervals are extended, then calculation efficiency improves, but measurement precision of balance fluctuations deteriorates
Solution Approach 1:
The patent implements dynamic valuation intervals that adjust based on account activity levels. During periods of high transaction volume, the system shortens valuation intervals to capture rapid balance fluctuations, while during low-activity periods, intervals are extended to maintain calculation efficiency. This dynamic adjustment allows the system to optimize both productivity and measurement precision according to real-time conditions, rather than using fixed intervals.
