Solution Overview

Problem

The inconvenience of obtaining and affixing physical postage stamps or shipping labels for delivery services, particularly when dropping off items at collection boxes, and the inefficiencies in online transactions for payment, make it difficult for senders to conveniently pay delivery fees for physical items.

Innovation Solution

A system and method for using digital stamps activated through a computerized user interface, allowing senders to request, receive, and accept delivery fees for physical items without physical indicia, using voice recognition and automated speech generation, and integrating with delivery service computing systems for item processing and delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical stamps or labels are used to indicate payment of delivery fee, then the delivery service can recognize payment, but the sender must obtain and affix physical indicia which is inconvenient

Engineering Contradiction:
Improveconvenience of paying delivery feeVSAvoidprocess complexity for obtaining and affixing stamps
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces physical stamps with digital stamp images that are captured by an imaging device. The digital copy of the stamp is then associated with the item through image processing and pattern recognition, eliminating the need for physical affixing while maintaining the payment indication function.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical process of physically affixing stamps with an automated imaging and recognition system. The imaging device captures the item, and software algorithms automatically detect and verify the digital stamp, replacing manual operations with automated electronic processing.

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

2Loss of time

If sender obtains stamps online through Internet transactions, then physical travel is avoided, but numerous steps including browsing and secure payment are required

Engineering Contradiction:
Improvetime for obtaining stampsVSAvoidsimplicity of obtaining stamps
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system allows senders to self-service by simply placing items in a collection box with digitally displayed or projected stamp images. The automated imaging and recognition system handles verification without requiring the sender to navigate online stores or complete payment transactions, making the process as simple as dropping off an item.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent enables preliminary payment and stamp issuance before item collection. Users can obtain digital stamps through various methods (online purchase, account credit, promotional offers) in advance, and the system stores these digitally. When items are deposited, the system automatically associates the pre-obtained digital stamps with the items, eliminating the need for same-day transactions.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If sender travels to retail location to obtain stamps, then stamps are obtained, but the sender must leave collection box usage and visit physical location

Engineering Contradiction:
Improveability to use collection boxVSAvoidtime for traveling to retail location
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent creates digital copies of postage stamps that can be displayed on screens or projected onto collection boxes. These digital stamp images serve the same function as physical stamps, allowing users to complete transactions remotely while maintaining the collection box drop-off convenience.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system introduces a digital intermediary layer between the user and the collection box. Digital stamp images displayed on screens or projected onto the box serve as the intermediary that bridges remote payment capabilities with physical drop-off convenience, eliminating the need for travel to retail locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If no physical indicator is placed on item, then convenience is improved, but delivery service cannot recognize payment status

Engineering Contradiction:
Improveconvenience of item preparationVSAvoidpayment recognition accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces physical stamp affixing with automated optical recognition. Imaging devices capture images of items, and software algorithms detect digital stamp images, verify their authenticity, and associate them with items. This electronic verification system maintains payment recognition reliability while eliminating the need for physical indicators on items.

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

Solution Approach 2:

The system implements feedback loops where the imaging and recognition system continuously monitors items at collection boxes, verifies digital stamp presence and validity, and provides real-time confirmation to both the sender and delivery service. This feedback mechanism ensures payment recognition accuracy without requiring physical stamps on items.

Inventive Principle:
Principle #23Feedback

AI summary

Systems, methods, interface devices, and media for the delivery of physical items using a digital stamp. Various implementations include operations such as receiving a request from a user to deliver an item to a destination using a digital stamp, wherein the item includes destination information and lacks any physical indicator that the delivery fee for the item has been paid or will be paid; receiving a destination address from the user; presenting a delivery fee for the item; and causing the generation of a digital stamp using the destination address and the delivery fee, which may be correlated with the item.
