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 to identify challenging delivery locations, prompting end users for additional address information and guiding transporters through enhanced navigation to ensure successful deliveries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system uses standard delivery addresses without verification, then the delivery process is simple and fast, but delivery success rate decreases due to vague or ambiguous addresses

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

Solution Approach 1:

The system performs address verification before the delivery process begins by checking if the provided address falls within an adverse delivery zone. This preliminary action identifies problematic addresses in advance, allowing the system to prompt users for additional information or adjust delivery expectations before the actual delivery attempt, thereby improving delivery success rate without adding complexity during the delivery execution phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by monitoring delivery outcomes and using this information to train machine learning models that identify adverse delivery zones. The feedback loop continuously improves the system's ability to recognize and handle difficult delivery locations, enabling more accurate prediction and prevention of delivery failures while maintaining operational simplicity.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system prompts users for additional address information, then delivery accuracy improves, but user experience and delivery speed deteriorate

Engineering Contradiction:
Improveaddress accuracyVSAvoiddelivery time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system applies local quality by providing targeted prompts for additional address information only when the machine learning model identifies that an address falls within an adverse delivery zone. For addresses in normal zones, the system proceeds with standard delivery without additional prompts. This localized approach ensures high address accuracy is pursued only when necessary, minimizing time loss for the majority of successful deliveries.

Inventive Principle:
Principle #3Local quality

3Reliability

If the system identifies adverse delivery zones using machine learning, then delivery reliability improves, but system complexity and computational resources increase

Engineering Contradiction:
Improvedelivery completion rateVSAvoidmachine learning processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements self-service by using the machine learning model to automatically identify adverse delivery zones and trigger appropriate responses without requiring manual intervention or complex real-time processing during delivery. The ML model processes historical data in advance to create zone classifications, and the system simply queries these pre-computed zones during delivery operations, reducing computational complexity while maintaining high delivery reliability.

Inventive Principle:
Principle #25Self-service

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.
