Solution Overview

Problem

Existing cargo handling technologies, such as those described in Patent Document 1, fail to detect and prevent misalignment of cargo on conveyance destinations other than forklifts, leading to potential cargo reversal or dropping during transport.

Innovation Solution

A vehicle-mounted device equipped with a spatial recognition device and analysis unit that determines loading misalignment by sensing information, allowing for appropriate loading and alignment of cargo on conveyance destinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a cargo sensor is provided to detect displacement near the upper end of the mast, then misalignment of cargo on the forklift can be rapidly detected, but misalignment of cargo on conveyance destinations other than the forklift cannot be detected

Engineering Contradiction:

Improvecargo alignment detection accuracyVSAvoidapplicability to different conveyance destinations

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The spatial recognition device is configured to detect not only cargo on the forklift but also cargo on conveyance destinations such as truck beds and containers. The device performs multiple functions including detecting the conveyance destination, detecting cargo position, and determining misalignment, making the system universally applicable to different loading scenarios and conveyance destinations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If cargo loading is performed without misalignment detection, then loading speed is maintained, but the transport target may be reversed or dropped after loading

Engineering Contradiction:

Improveloading speedVSAvoidcargo transport stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs misalignment determination before the cargo is fully loaded and secured on the conveyance destination. By detecting potential misalignment issues during the loading process and alerting the operator in advance, the system enables preliminary correction of positioning errors, preventing cargo reversal or dropping that would occur if loading proceeded without detection.

Inventive Principle:

Principle #10Preliminary action

AI summary

A vehicle-mounted device includes an analysis unit and a control unit. The analysis unit detects an insertion target into which an insertion blade can be inserted, on the basis of sensing information acquired from a spatial recognition device. The control unit performs a loading misalignment determination to determine whether or not the insertion target loaded on a conveyance destination is misaligned from the conveyance destination on the basis of the sensing information.
