Solution Overview

Problem

Conventional food delivery services are often slow, taking a long time between order placement and delivery, as couriers may not be optimally located or inventoried to provide quick service.

Innovation Solution

A system that enables dynamic courier placement and inventory management using mobile devices and location sensors to create delivery zones, allowing couriers to quickly deliver items by predicting buyer locations and optimizing courier routes for fast delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional delivery services are used, then delivery coverage area is large, but delivery time is long

Engineering Contradiction:
Improvedelivery speedVSAvoiddelivery time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The system pre-positions couriers in strategic locations before orders are placed. Couriers are assigned to specific zones and remain ready to accept orders, eliminating the need for customers to wait for courier assignment and travel time. This preliminary positioning of delivery personnel directly reduces delivery time while maintaining service coverage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The delivery service area is divided into multiple zones, with couriers assigned to specific zones. This segmentation allows the system to manage courier positions efficiently and reduce travel distances. By dividing the service area into smaller segments, the system achieves faster local delivery speeds while maintaining overall coverage.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If couriers are distributed widely to cover large areas, then delivery coverage is extensive, but delivery time increases

Engineering Contradiction:
Improvedelivery zone coverageVSAvoiddelivery speed
Core Design Contradiction:
Area of stationary objectVSSpeed

Solution Approach 1:

The system dynamically adjusts courier assignments and delivery zones based on real-time conditions such as order volume, courier availability, and traffic patterns. Delivery zones are not fixed but adapt to current demand, allowing the system to maintain extensive coverage while optimizing for speed in high-demand areas. This dynamic reconfiguration enables the system to balance coverage and speed continuously.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If couriers are positioned close to buyers for fast delivery, then delivery time is reduced, but system complexity increases

Engineering Contradiction:
Improvedelivery timeVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system continuously monitors courier positions, order placements, and delivery performance, using this feedback to optimize courier positioning and zone assignments. Real-time data from mobile devices and location sensors feeds back to the assignment system, which automatically adjusts courier positions to maintain optimal proximity to buyers. This automated feedback loop manages system complexity by using algorithms to handle the dynamic optimization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses automated algorithms and mobile device applications to manage courier assignments and positioning without requiring complex manual coordination. Couriers use mobile apps to receive assignments and report status, while the system automatically optimizes positioning based on demand patterns. This self-service approach reduces operational complexity while maintaining fast delivery capability.

Inventive Principle:
Principle #25Self-service

AI summary

In some examples, a service provider may receive a plurality of communications indicating buyer accesses to respective item-ordering applications on respective buyer devices. The service provider may determine that the buyer accesses occurred at respective buyer locations outside of a current delivery region. The service provider may determine a cluster of the respective buyer locations, and may further determine, based on the cluster, a recommended courier location for extending the delivery region to include a new area including the cluster. Additionally, in some cases, the service provider may determine a recommended courier location based on a plurality of past delivery locations. Further, in response to receiving an indication of a delivery location from a buyer device, the service provider may determine that a courier is within a threshold delivery travel time to the delivery location prior to providing item information to the buyer device.
