Solution Overview

Problem

Logistics platforms face inefficiencies and delays in delivering perishable goods from providers located in high congestion commercial areas due to challenges in accurate location, status, and routing mechanisms.

Innovation Solution

Implementing a depot dispatch protocol that aggregates orders using autonomous vehicles and neural networks to optimize delivery routes, scheduling, and order batching, with automated locker systems for secure order transfer and reduced human error.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional delivery routing is used in high congestion commercial areas, then delivery coverage is maintained, but delivery time and efficiency deteriorate

Engineering Contradiction:
Improvedelivery efficiencyVSAvoiddelivery time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent introduces autonomous vehicles as intermediary carriers between providers and customers. These autonomous vehicles receive orders from providers, transport them to aggregation depots, and facilitate efficient order batching and consolidation. This intermediary system bypasses congestion issues by using optimized routing and automated operations, thereby improving delivery efficiency while reducing delivery time in high congestion commercial areas.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual order handling is used, then flexibility is maintained, but error rate and operational complexity increase

Engineering Contradiction:
Improveorder accuracyVSAvoidoperational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements automated locker systems that enable self-service order retrieval and handoff. Orders are automatically deposited into lockers at aggregation depots, and the system automatically manages order tracking, status updates, and customer notification. This self-service automation eliminates manual handling errors while the integrated software platform manages operational complexity centrally, providing reliability without proportionally increasing operational burden.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If direct provider-to-customer delivery is used, then delivery speed is maintained, but routing accuracy and order consolidation efficiency deteriorate

Engineering Contradiction:
Improverouting accuracyVSAvoidorder consolidation efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent merges multiple orders into consolidated batches at aggregation depots. The system groups orders by destination, consolidates them into efficient delivery batches, and routes them together using optimized paths. This merging process improves routing accuracy by planning routes based on consolidated destinations rather than individual orders, and enhances order consolidation efficiency by systematically batching orders before final delivery to customers.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Provided are various systems and processes for improving last-mile delivery of real-time, on-demand orders for perishable goods. In one aspect, a method is provided for aggregating on-demand deliveries using a depot dispatch protocol which may implement automated order transport and retrieval systems. The method comprises dispatching merchant couriers to transport on-demand orders from merchants to a merchant depot where the orders are aggregated and batched based on optimized delivery routes and destination proximities. Batches of orders are then transported to a customer depot corresponding to an area of delivery destinations. Orders are then assigned to delivery couriers for completion of delivery to customers. Such delivery routing systems and processes may be implemented alongside a delivery tracking system for generating estimated time of arrival predictive updates for real-time delivery of perishable goods. The described mechanisms improve courier efficiency, improve delivery tracking, and reduce overall delivery times.
