Dynamic Fee Calculation System for Online Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic payment services face challenges in dynamically adjusting transaction charges to adapt to changing market conditions and facilitate agreements with merchants, as they rely on fixed or static fee calculations that do not easily accommodate new market dynamics.
Innovation Solution
A dynamic and auditable fee calculation system that uses a microprocessor to select an initial base fee based on either a default or overriding fee, applying adjustments when specific conditions are met, allowing for flexible fee determination linked to fee types, country codes, and client identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed or static transaction charges are used, then the fee calculation system is simple and stable, but it cannot adapt to changing market conditions or facilitate flexible agreements with merchants
Solution Approach 1:
The patent implements dynamic fee calculation by introducing adjustable parameters including base fees, adjustment factors, and condition sets that can be modified in real-time. The system transitions from static fixed fees to dynamic fees that automatically adjust based on market conditions, transaction characteristics, and pre-defined conditions, enabling adaptability without requiring complete system redesign
Solution Approach 2:
The fee calculation is segmented into multiple independent components: base fee determination, condition evaluation, adjustment factor application, and final fee calculation. This modular segmentation allows each component to be independently configured and modified, providing flexibility for market adaptation while maintaining manageable system complexity through clear separation of concerns
2Adaptability or versatility
If a flexible fee framework with multiple adjustments and conditions is implemented, then the system can adapt to new market conditions and facilitate merchant agreements, but the system complexity increases
Solution Approach 1:
The patent creates a universal fee calculation framework that handles multiple fee types (transaction fees, currency conversion fees, service fees) through a single unified system. The same core mechanism processes different fee structures by applying appropriate base fees and adjustment factors, eliminating the need for separate calculation systems for each fee type and reducing overall complexity despite enhanced flexibility
Solution Approach 2:
The system manages complexity by changing parameters (base fees, adjustment factors, condition thresholds) rather than changing the fundamental calculation structure. This allows flexible fee configurations through parameter adjustment alone, maintaining a stable core algorithm while adapting to different market conditions and merchant agreements through simple parameter modifications
3Measurement precision
If dynamic fee adjustments are applied based on conditions, then the fee calculation becomes more accurate and market-responsive, but the calculation time and processing complexity increase
Solution Approach 1:
The patent implements preliminary action by pre-defining condition sets, adjustment factors, and base fees before transactions occur. These parameters are configured in advance based on market conditions and merchant agreements, allowing the system to perform simple lookups and direct calculations during actual transactions rather than performing complex real-time analysis, thus maintaining accuracy while minimizing processing time

AI summary
Various methods, apparatus, and systems are disclosed for calculating a fee linked to an online financial transaction, with improved flexibility and availability through caching and refreshing of fee calculation data. In one embodiment, a method includes extracting fee calculation data into a data cache associated with control data that is updated in response to refreshing of the data cache; receiving a fee calculation request linked to an online transaction associated with a fee type, a country code, and a client identifier; and then selecting, by looking up the data cache, a base fee from either a default fee determined by the fee type and the country code or from an overriding fee associated with the client identifier. The method further includes calculating a transaction fee for the online transaction based at least in part on the base fee; and verifying the control data to transmit the calculated transaction fee.
