Solution Overview

Problem

The gate-in process at distribution centers is time-consuming and prone to inaccuracies due to manual handling of paperwork by truck drivers, which can be streamlined for efficiency and accuracy.

Innovation Solution

A yard management system utilizing autonomous yard vehicles and a mobile application that allows drivers to pre-populate electronic forms with load information, eliminating the need for manual data entry and guiding vehicles to correct locations within the distribution center, thereby reducing interaction time and potential human errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual paperwork handling is used at the gate-in process, then drivers can submit freight information, but the process becomes time-consuming and inaccurate

Engineering Contradiction:
Improvegate-in process speedVSAvoidtime consumed in gate-in process
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical paperwork handling with an automated electronic system. Drivers use mobile devices to electronically submit freight information, which is then automatically processed by the yard management system. This substitution eliminates manual data entry, reduces errors, and significantly speeds up the gate-in process while maintaining accurate tracking of all freight movements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual data entry is performed by drivers, then load information can be recorded, but human errors increase and accuracy decreases

Engineering Contradiction:
Improvedata accuracyVSAvoiderrors in load information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system replaces manual data entry with automated electronic data capture and processing. Mobile devices enable drivers to input information electronically, which is then validated and processed by the yard management system's automated algorithms. This eliminates transcription errors, ensures data consistency, and maintains accurate records of all freight information throughout the supply chain.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If drivers interact extensively with distribution center staff, then paperwork can be verified, but interaction time increases and efficiency decreases

Engineering Contradiction:
Improvegate-in process simplicityVSAvoidinteraction time at gate
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements a self-service system where drivers independently complete the gate-in process using mobile devices. Drivers can electronically submit freight information, track their shipments in real-time, and receive automated notifications without requiring extensive interaction with distribution center staff. The yard management system automatically verifies and processes the information, enabling drivers to complete transactions independently and significantly reducing wait times at the gate.

Inventive Principle:
Principle #25Self-service

4Loss of information

If traditional gate-in processes are used, then freight check-in can be performed, but the process lacks real-time tracking and updates

Engineering Contradiction:
Improveload status informationVSAvoidtime to obtain load status updates
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The yard management system implements real-time feedback mechanisms through mobile devices. Drivers receive immediate automated notifications about their freight status, including check-in confirmation, current location, and estimated arrival times. The system continuously updates drivers on the status of their loads throughout the distribution process, enabling proactive decision-making and eliminating the need for drivers to manually inquire about their shipments.

Inventive Principle:
Principle #23Feedback

AI summary

Yard management systems and methods are described. A yard management system comprises a database holding load information, a mobile application associated with a user account and executable on a mobile device. The mobile application when executed acquires the identifications of the load, queries the database for the load information, and generates a machine-readable representation corresponding to the identifications of the load, an autonomous yard vehicle configured to mechanically couple with a cargo trailer. The system further comprises a computing system programmed to, in response to detecting the mobile device at the transfer location, navigate to the cargo trailer and guide the coupling between the autonomous yard vehicle and the cargo trailer.
