Solution Overview

Problem

Existing electronic transaction systems lack dynamic management and adjustment capabilities after a transaction is completed, limiting user control and flexibility.

Innovation Solution

An electronic transaction system that allows users to select and modify payment arrangements, including financial instruments and payment deferral options, even after the transaction has been conducted, through a user interface and automated processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic transaction systems allow dynamic modification of payment arrangements after transaction completion, then user control and flexibility are improved, but system complexity increases

Engineering Contradiction:

Improveuser controlVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the transaction management process into distinct phases: initial transaction execution, post-transaction analysis, and modification implementation. This allows the complex functionality to be divided into manageable components that can be independently developed and maintained, reducing overall system complexity while enabling dynamic payment arrangement modifications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by establishing the foundational transaction record and payment arrangement structure during the initial transaction phase. This preliminary setup enables subsequent modifications without requiring complete system redesign, as the base structure is already in place to accommodate future changes.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the system provides comprehensive post-transaction management capabilities, then financial management optimization is improved, but processing time increases

Engineering Contradiction:

Improvefinancial management optimizationVSAvoidprocessing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system implements periodic action by allowing users to modify payment arrangements at discrete intervals after transaction completion, rather than requiring continuous processing. This periodic approach enables comprehensive financial management capabilities while maintaining efficient processing times by batching modification operations rather than handling them continuously.

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If the system allows payment arrangement modifications after transaction completion, then flexibility is improved, but transaction stability decreases

Engineering Contradiction:

ImproveflexibilityVSAvoidtransaction stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system employs feedback mechanisms by monitoring transaction status, modification requests, and system state changes in real-time. This feedback loop ensures that payment arrangement modifications are processed only when appropriate conditions are met, maintaining transaction stability while enabling necessary flexibility for post-transaction management.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system applies dynamics by making the payment arrangement structure adaptable rather than fixed. The transaction record maintains its core stability while allowing dynamic modifications to payment arrangements through controlled update mechanisms that preserve data integrity and transaction consistency.

Inventive Principle:

Principle #15Dynamics

AI summary

Methods and systems are presented for providing comprehensive payment transaction services through a digital wallet. The digital wallet enables a user to conduct an electronic transaction with a merchant or another user. In one aspect, the digital wallet may modify a payment arrangement of the electronic transaction. For example, the digital wallet may determine a first payment arrangement that specifies one or more financial instruments and a payment deferral time period for the electronic transaction. Subsequent to processing the electronic transaction, the digital wallet may determine a different, second payment arrangement for the electronic transaction. The digital wallet may modify the electronic transaction based on the second payment arrangement without canceling the electronic transaction. In another aspect, the digital wallet may manage rewards by dynamically withholding rewards, releasing the rewards, and/or distributing at least portions of the rewards to different users.
