Solution Overview

Problem

Existing systems lack the ability to proactively identify, detect, and predict multi-party transactions or events that result in shared expenses, leading to time-consuming and error-prone manual processes for settling up group-related transactions.

Innovation Solution

A system that automatically identifies potential multi-party events and transactions by analyzing user data, determines associated parties, and manages payment delegation based on an optimal scheme, linking received payments to the original transaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual processes are used to identify and settle multi-party transactions, then system complexity is low, but time consumption and error rate increase

Engineering Contradiction:
Improvetransaction settlement efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary identification and classification of multi-party transactions before settlement. Event detection modules proactively identify potential multi-party events by analyzing transaction patterns, user relationships, and event characteristics in advance, preparing the groundwork for automated settlement processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an automated decisioning system as an intermediary between transaction detection and settlement. This system includes event detection modules, party identification modules, and payment scheme determination modules that mediate the complex process of identifying, verifying, and settling multi-party transactions automatically.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If automated detection of multi-party events is implemented, then transaction identification accuracy improves, but data processing requirements increase

Engineering Contradiction:
Improveevent detection accuracyVSAvoiddata processing load
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The automated detection system is segmented into multiple specialized modules: event detection modules that identify potential multi-party events, party identification modules that determine involved parties, and payment scheme determination modules that calculate settlement amounts. This segmentation allows each module to focus on specific aspects of detection, improving accuracy while distributing processing load efficiently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial action by selectively analyzing only transactions that exhibit characteristics of multi-party events, rather than processing all transactions uniformly. The event detection modules use heuristics and patterns to identify candidate events, then apply more rigorous analysis only to these candidates, reducing overall data processing requirements while maintaining high detection accuracy.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Methods, systems, devices, and computer-readable media for detecting multi-party events and transactions are provided. User data may be monitored to detect data associated with an event involving multiple individuals, such as by identifying transaction data associated with certain types of merchants and/or scheduling, calendar, or correspondence data indicative of an event. The data may be further analyzed to identify a date, location, and/or parties associated with the event. A multi-party event may be generated. The user data may continue to be monitored to identify transactions associated with multiple parties and occurring during a time and/or at a location of the event. At a conclusion of the event, the transactions may be aggregated and an optimal payment scheme may be determined for settlement of the transactions between the parties. In accordance with the determined payment scheme, delegation of portions of the aggregated transactions may be initiated for settlement amongst the parties.
