Solution Overview

Problem

Existing web services and applications that comply with standards such as those set by the World Wide Web Consortium (W3C) are limited to features supported by these standards, often requiring users to manually scroll through numerous transaction options and navigate between tabs to compare terms and conditions, which is inefficient, especially on mobile devices with limited screen area and processing power.

Innovation Solution

Implementing a client-side language model-based option selection framework that leverages locally stored transaction data and histories to seamlessly provide optimized transaction instrument suggestions, overriding the typical sequence of events triggered by standards-compliant transaction handlers, using models like GPT-3 or GPT-4 to predict user preferences and reduce fraudulent transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a standards-compliant transaction handler provides all registered transaction instruments, then users have access to complete transaction options, but users must manually scroll through numerous options and navigate between tabs to compare terms, increasing operation time and complexity

Engineering Contradiction:
Improveease of transaction instrument selectionVSAvoidtime to compare and select transaction instrument
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system employs an option selection language model that automatically analyzes transaction data and transaction instrument terms to select optimal instruments without requiring manual user comparison. The model self-serves by processing the information and presenting recommended options, eliminating the need for users to manually scroll through and compare numerous transaction instruments.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of scrolling through options and comparing terms with an automated language model-based system. The language model processes transaction data and instrument terms computationally to identify optimal options, substituting human cognitive effort with automated AI-based analysis.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a standards-compliant transaction handler provides all registered transaction instruments, then users have access to complete transaction options, but the interface becomes complex and requires navigation between multiple tabs

Engineering Contradiction:
Improveavailability of transaction optionsVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts and presents only the most relevant transaction instrument options based on the language model's analysis of transaction data and instrument terms. Instead of displaying all registered transaction instruments, the model selectively extracts and highlights the optimal options, simplifying the interface while maintaining access to complete options behind the scenes.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the transaction instrument selection process into two parts: complete options remain available in the background system, while the foreground interface displays only the model-recommended optimal options. This segmentation allows the system to maintain full versatility while presenting a simplified, less complex user interface.

Inventive Principle:
Principle #1Segmentation

3Reliability

If client-side processing is used for option selection, then user privacy and security are enhanced, but processing power requirements increase on mobile devices

Engineering Contradiction:
Improvesecurity and privacyVSAvoidprocessing energy on mobile device
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements partial client-side processing where the language model runs locally on the mobile device to enhance security and privacy. However, the model is designed to process only the essential transaction data and instrument terms needed for option selection, rather than performing exhaustive analysis, thus balancing local processing benefits with energy consumption constraints.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Disclosed are various approaches for language model based options selections. In one example, a service (122) can generate a user interface (167) that identifies user interactions received from a client device (106) to register transaction instruments. Transaction facilitation websites (152) can be scraped to identify transaction instrument terms for the registered transaction instruments (173). An option selection language model (126) can be generated and trained to select a subset of the registered transaction instruments (173). The option selection language model (126), the transaction instrument data (172), and the transaction instrument terms (156) can be transmitted to the client device (106).
