Solution Overview

Problem

End users often face difficulties with deliveries due to vague or ambiguous addresses, especially in areas where transporters have historically struggled to locate the delivery destination, leading to incomplete or delayed deliveries.

Innovation Solution

A central server computer system determines adverse delivery zones using machine learning methods and historical delivery data, prompting end users for additional address information and providing it to transporters to ensure successful deliveries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system uses standard address verification, then the process is simple and fast, but delivery failures increase in ambiguous areas

Engineering Contradiction:
Improvedelivery success rateVSAvoidaddress verification process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by identifying adverse delivery zones in advance using historical delivery data and machine learning models. Before a delivery attempt, the system determines whether a location falls within an adverse delivery zone and prompts the user to provide additional address information proactively, preventing delivery failures before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary verification process between the standard address input and the delivery execution. When a location is identified as being in an adverse delivery zone, the system inserts an additional verification step where users must provide supplementary address details, which then serve as the basis for successful delivery navigation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the system prompts users for additional address information, then delivery accuracy improves, but user interaction time increases

Engineering Contradiction:
Improveaddress accuracyVSAvoiduser interaction time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system applies local quality by providing enhanced address verification only in specific adverse delivery zones where it is most needed, rather than requiring additional information for all addresses. The machine learning model identifies specific geographic areas with high delivery failure rates, and only in those localized areas does the system prompt users for additional address details, leaving standard verification unchanged in other regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the verification parameter dynamically based on the delivery location. Instead of using a fixed verification approach, the system adjusts the level of verification required based on whether the destination is in an adverse delivery zone. The machine learning model evaluates location parameters and determines the appropriate verification depth, switching between standard and enhanced verification modes as needed.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the system uses historical delivery data to identify adverse zones, then delivery reliability improves, but data processing complexity increases

Engineering Contradiction:
Improvedelivery completion rateVSAvoiddata processing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically analyzing historical delivery data and maintaining its own adverse delivery zone database. The machine learning model continuously learns from past delivery outcomes and updates its identification of adverse zones without external intervention. This self-service approach eliminates the need for manual analysis of delivery patterns while building increasingly accurate predictive models.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where delivery outcomes are fed back into the machine learning model to refine future adverse zone identifications. Historical delivery data is continuously analyzed to update the model's understanding of which locations are most difficult to serve, allowing the system to improve its predictions over time based on actual delivery performance.

Inventive Principle:
Principle #23Feedback

AI summary

A method includes a server computer receiving delivery data associated with a plurality of deliveries in a geographical area. The server computer can determine a plurality of adverse delivery zones in the geographical area. The server computer can receive a fulfillment request to deliver an item to an end user at a specific location and determine if the specific location is in one of the adverse delivery zones. If the specific location is in one of the adverse delivery zones, the server computer can take one or more additional actions to ensure that the item is delivered to the end user at the specific location.
