Solution Overview

Problem

Current methods for loading and unloading vehicles on transporter vehicles are inefficient, requiring manual intervention and lacking automation, which wastes time and increases the complexity of tracking vehicle inventory.

Innovation Solution

A system utilizing geolocation data and geofences to determine the entry and parking location of subject vehicles within transporter vehicles, enabling autonomous or semi-autonomous vehicle management and coordination, including the use of weight sensors and cameras for verification and data science for optimal parking determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual intervention is used for loading and unloading vehicles, then the process requires human coordination and tracking, but this increases time consumption and operational complexity

Engineering Contradiction:
Improveloading and unloading automationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

Vehicles autonomously determine their own parking locations within the transporter using geolocation data and geofence technology. Each vehicle receives navigation instructions to autonomously navigate to its assigned position, eliminating the need for manual coordination and tracking by human operators.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical tracking and coordination systems with automated electronic monitoring using geolocation data, geofences, and communication modules. This substitution enables automatic vehicle tracking and position verification without human intervention.

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

2Productivity

If manual tracking of vehicle inventory is used, then human operators can monitor vehicle positions, but this reduces efficiency and increases operational time

Engineering Contradiction:
Improveloading and unloading efficiencyVSAvoidtime for vehicle management
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system continuously receives geolocation data from vehicles and automatically compares it against predefined geofences to determine vehicle positions and status. This real-time feedback mechanism enables automatic tracking and monitoring of vehicle inventory without manual intervention, significantly improving efficiency and reducing time loss.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an automated coordination system that acts as an intermediary between vehicles and the transporter management system. This intermediary automatically processes vehicle positions, determines parking locations, and provides navigation instructions, eliminating the need for manual tracking and reducing operational time.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If automated geolocation tracking is implemented, then vehicle positions can be automatically determined, but this requires sophisticated monitoring systems

Engineering Contradiction:
Improvevehicle position accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses universal geolocation technology and geofence parameters that can be applied across multiple vehicles and transporters. The same monitoring framework handles position tracking, parking determination, and navigation instructions, reducing overall system complexity through standardized multi-functional components.

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