Solution Overview

Problem

Existing container positioning technologies face challenges such as high energy consumption and short battery life due to long transportation periods, low precision and frequency of positioning data, and signal loss in complex environments, leading to decreased accuracy and increased costs.

Innovation Solution

A digital association and high precision positioning and tracking system that divides container positioning into two stages: associated state positioning using high-precision carrier data and non-associated state positioning using container terminal data. This system employs a machine learning trajectory point prediction and matching algorithm to improve positioning accuracy and uses carrier-container digital association to ensure accurate tracking during multimodal transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If container positioning equipment is installed on the container shell and powered by micro-battery, then the container can be tracked during transportation, but the power consumption is large and the battery life is short due to long transportation periods and unmanned maintenance

Engineering Contradiction:
Improvepositioning reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent merges the positioning function from the container terminal to the carrier terminal. The carrier terminal, which has stable power supply from the vehicle, performs positioning for both the carrier and the container. This eliminates the need for independent micro-battery positioning equipment on the container, solving the power consumption problem while maintaining positioning reliability through the association relationship between carrier and container.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If container collects low-precision and low-frequency positioning trajectory data during transportation, then the positioning cost is reduced, but the positioning accuracy decreases and trajectory loss occurs in complex environments such as tunnels, elevated buildings, and tall buildings

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsignal loss
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent introduces the carrier terminal as an intermediary to solve signal loss problems. When the container is in associated state with the carrier, the carrier terminal acts as a mediator to provide continuous high-precision positioning data even in complex environments where GPS/Beidou signals are lost. This ensures trajectory continuity without requiring the container terminal to continuously transmit data, thus avoiding signal loss issues.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If high-precision positioning module is installed on the container, then the positioning accuracy is improved, but the installation cost is too high

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent makes the carrier terminal universal by enabling it to perform multiple functions: carrier positioning, container positioning, and trajectory prediction. Instead of requiring expensive high-precision positioning modules on each container, the carrier terminal serves multiple containers and performs multiple functions, significantly reducing system cost while maintaining high positioning accuracy through the association mechanism and machine learning algorithms.

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

4Loss of information

If container positioning technology is applied to multimodal transport, then the container transfer information can be provided, but the existing technology does not reflect real-time and accurate positioning during handover and production

Engineering Contradiction:
Improvetransfer information accuracyVSAvoidresponse time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using the machine learning trajectory prediction algorithm to predict future container positions based on historical trajectory data. This allows the system to proactively provide accurate positioning information for upcoming handover points and production facilities, enabling better transportation plan formulation and real-time monitoring without waiting for actual position updates, thus reducing information loss and response time.

Inventive Principle:
Principle #10Preliminary action
