Solution Overview

Problem

Individuals often accumulate disparate collections of receipts, making it difficult to retain or find specific receipts for purposes such as returns, rebates, or expense documentation.

Innovation Solution

An online content management service that collects, analyzes, and organizes receipts from various sources, including user uploads, email messages, and merchant partnerships, automatically filing them into structured folders based on merchant for easy retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If receipts are collected manually and stored in disparate locations, then users have control over their receipts, but it becomes difficult to retain and find specific receipts

Engineering Contradiction:
Improveease of receipt retrievalVSAvoiddifficulty in finding specific receipts
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent combines multiple receipt storage sources (email accounts, mobile devices, cloud storage) into a single centralized online repository. The system aggregates receipts from various locations and presents them through a unified interface, allowing users to access all receipts in one place rather than searching through disparate locations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the large collection of receipts into organized categories and folders (e.g., by merchant, date, or type). This segmentation allows users to quickly locate specific receipts by navigating through structured categories rather than searching through an unorganized mass of all receipts.

Inventive Principle:
Principle #1Segmentation

2Productivity

If an online content management service automatically collects and organizes receipts from multiple sources, then receipt organization and retrieval efficiency improve, but system complexity increases

Engineering Contradiction:
Improvereceipt management efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs automatic receipt collection, classification, and organization without requiring user intervention. It autonomously connects to email accounts, mobile devices, and cloud storage, retrieves receipts, and files them into appropriate categories based on embedded metadata, eliminating the need for manual sorting while improving productivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The online content management service acts as an intermediary between various receipt sources (email, mobile devices, cloud storage) and the user. It provides a unified interface that abstracts away the complexity of multiple sources, allowing users to access receipts from anywhere without needing to understand the underlying system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If receipts are automatically filed into structured folders based on merchant, then locating specific receipts becomes easier, but the automation process requires sophisticated analysis capabilities

Engineering Contradiction:
Improvetime to locate receiptVSAvoidanalysis capability complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system performs preliminary classification and organization of receipts at the time of collection, rather than waiting until the user needs to search. By pre-filing receipts into structured folders based on merchant, date, and type during the automatic collection process, the system eliminates future search time without requiring complex analysis at retrieval moment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual receipt sorting and filing mechanisms with automated optical character recognition (OCR) and image analysis technology. The system automatically reads receipt images, extracts merchant and transaction information, and files them appropriately, substituting sophisticated automated analysis for what would otherwise require manual effort.

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

AI summary

An online content management service can collect and store receipts for a user from a variety of sources, including images captured by the user, messages received for the user at a messaging service or message management service, and/or receipts directly uploaded to the online content management service by a merchant. In the case of receipts provided as messages, a user can interact with a message management service to identify messages as receipts, and the message management service can upload such messages to the online content management service.
