Solution Overview

Problem

In self-driving delivery vehicles, the unloading and delivery of packages require human intervention, leading to labor costs.

Innovation Solution

A delivery system with a self-driving vehicle featuring a first space and a second space, a delivery robot, and a moving device that automatically moves packages from the first space to the second space for unloading, using a first bar and a second bar to position and drop packages, and a door that functions as a slope for the robot to enter and exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If packages are delivered by a self-driving vehicle, then delivery efficiency is improved, but labor costs increase due to required human intervention for unloading and delivery

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidautomation of unloading and delivery
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The delivery robot autonomously performs package reception, unloading, and delivery without human intervention. The robot receives packages from the vehicle through the opening, navigates independently to delivery destinations, and returns to the vehicle automatically, enabling the system to serve itself and eliminating the need for human workers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The delivery robot acts as an intermediary between the self-driving vehicle and the delivery destination. It receives packages from the vehicle's storage space, transports them to destinations, and returns to the vehicle for the next package, serving as an automated mediator that bridges the gap between vehicle and destination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If a delivery robot is used to receive and deliver packages, then labor costs are reduced, but device complexity increases

Engineering Contradiction:
Improveautomation of unloading and deliveryVSAvoidcomplexity of delivery system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The delivery system is segmented into distinct functional modules: the self-driving vehicle for transport, the delivery robot for autonomous delivery operations, and the opening mechanism for package transfer. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by dividing complex functions into manageable parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The delivery robot is designed as a multi-functional device that can perform multiple operations: receiving packages from the vehicle, navigating to various delivery destinations, returning to the vehicle, and repeating the cycle. This universality reduces the need for multiple specialized devices and simplifies the overall system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If packages are stored in multiple tiers with openings, then package accessibility is improved, but device complexity increases

Engineering Contradiction:
Improvepackage accessibilityVSAvoidcomplexity of storage structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage system utilizes a vertical multi-tier arrangement with openings in the lowermost tier, transforming the horizontal storage concept into a three-dimensional structure. This vertical dimensionality allows multiple packages to be stored in different levels while maintaining accessibility through the opening, optimizing space utilization without proportionally increasing complexity.

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

AI summary

A delivery system includes a self-driving vehicle, a delivery robot, an information processing device, and a moving device. The self-driving vehicle includes a first space and a second space located below the first space, the first space having at least one tier on which packages are loaded with an opening being formed in a part of at least a lowermost tier. The moving device is installed on the lowermost tier of the first space to move a package to the opening. The delivery robot is parked at a predetermined position where the package dropping from the lowermost tier is receivable below the opening in the second space. The information processing device controls the moving device to move the package to the opening to drop the package from the opening, so that the delivery robot receives the dropped package.
