Solution Overview

Problem

Consumers often forget about previously purchased products, which retain market value, and lack convenient local transaction opportunities to sell them, leading to lost financial opportunities.

Innovation Solution

A system and method utilizing transaction circuitry on mobile devices to identify and facilitate local transactions of previously purchased products by scanning email messages for relevant items, allowing users to set privacy controls, calculate sale prices, and connect with potential buyers within proximity using mobile apps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If consumers rely on traditional retail channels to sell products, then they can access broad market opportunities, but they incur transportation costs and time losses

Engineering Contradiction:
Improvetransportation costsVSAvoidmarket access
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent transitions the transaction model from physical location-based retail to digital location-based transactions. By using GPS coordinates and mobile devices, the system creates a new dimensional space where buyers and sellers can connect remotely while maintaining local transaction benefits, eliminating transportation needs while preserving market accessibility

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a digital intermediary platform that connects buyers and sellers through mobile devices. This intermediary matches participants based on geographic proximity and product categories, enabling local transactions without requiring physical presence at traditional retail locations, thus reducing transportation costs while maintaining market versatility

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If consumers forget about previously purchased products, then those products retain market value, but consumers lose financial opportunities

Engineering Contradiction:
Improveproduct awarenessVSAvoidfinancial opportunities
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent performs preliminary actions by automatically scanning email messages to identify purchased products before consumers forget them. The system extracts product information, categorizes items, and prepares them for potential sale, ensuring products are listed for transaction before consumer awareness fades, thereby preventing financial loss

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms that notify consumers about products identified from their email communications. The system provides feedback on potential saleable items, allowing consumers to review and confirm products they may have forgotten, thus recovering awareness and preventing financial opportunities from being lost

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the system accesses email data to identify products, then transaction accuracy improves, but privacy concerns increase

Engineering Contradiction:
Improveproduct identification accuracyVSAvoidprivacy risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by implementing differentiated privacy controls for different data elements. The system allows consumers to selectively control which email accounts and which specific product information are accessed and shared, enabling precise product identification while maintaining granular privacy protection for sensitive information

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments email data access by individual accounts and product types. The system processes email messages separately, identifies products from specific emails, and allows independent privacy controls for each data segment. This segmentation enables accurate product identification from relevant emails while isolating and protecting unrelated private information

Inventive Principle:
Principle #1Segmentation

AI summary

Methods, apparatus, systems, and articles of manufacture are disclosed to facilitate participant connection. An example apparatus includes at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to authorize access to an e-mail account, parse messages corresponding to the e-mail account to identify parameters, generate a list of candidate products associated with the parameters, publish the list with a first combination of information, in response to a first trigger, publish a second combination of information, and cause one of the candidate products from the list of candidate products to be at least one of removed or maintained based on a second trigger.
