Solution Overview

Problem

Conventional point-of-sale systems limit customer flexibility in receiving and managing digital receipts, as they are often pre-configured and not searchable, restricting users' ability to customize or extract useful information from transaction data.

Innovation Solution

A system and method for searching digital receipts on a mobile device, allowing users to select and apply search criteria such as payment methods or date ranges, enabling users to efficiently retrieve and manage their digital receipts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If digital receipts are provided as separate digital data, then customers can receive electronic receipts, but customers have limited ability to change how digital receipt data is viewed

Engineering Contradiction:
Improvereceipt format flexibilityVSAvoidcustomer control over receipt display
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system allows customers to independently configure and customize their own receipt display preferences through a user interface on their mobile devices. Customers can select which receipt attributes to display (e.g., promotional offers, loyalty points, item details) without requiring merchant intervention or POS system reconfiguration, thereby achieving both adaptability and ease of operation.

Inventive Principle:
Principle #25Self-service

2Loss of information

If digital receipts are generated as images of paper receipts, then customers can view transaction information, but customers are limited in performing further operations based on the content

Engineering Contradiction:
Improvetransaction information accessibilityVSAvoidoperational flexibility with receipt data
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The system replaces static image-based receipt delivery with dynamic structured data delivery. Instead of providing customers with unsearchable image files, the system transmits machine-readable transaction data (e.g., in JSON or XML format) that can be programmatically processed, searched, filtered, and integrated with other applications, thereby enabling diverse operations while preserving all transaction information.

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

3Ease of manufacture

If POS systems use proprietary on-board software, then merchants can make minor programming adjustments, but merchants have limited ability to add functionality to the POS system

Engineering Contradiction:
Improvesoftware customization capabilityVSAvoidPOS system functionality expansion
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The system implements a universal configuration interface that allows merchants to customize receipt display parameters and add functional features through a standardized platform. Rather than requiring proprietary software modifications for each feature, the system provides a flexible configuration framework that supports multiple functions (promotional displays, loyalty programs, detailed itemization) through a common architecture, enabling both ease of customization and functional versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention extends to methods, systems, and computer program products for searching digital receipts at a mobile device. A customer mobile device receives and stores one or more digital receipts. The one or more digital receipts correspond to transactions conducted with a merchant. A user can select search criteria for searching stored digital receipts. The search criteria can be applied to stored digital receipts. Any stored digital receipts that satisfy the search criteria can be returned for display. In some embodiments, search criteria are selected to search for digital receipts associated with a specified payment method, such as, for example, cash, check, credit card, debit card, gift card, etc. In other embodiments, search criteria are selected to search for digital receipts having a purchase date within a specified purchase date range.
