Solution Overview

Problem

Conventional systems face challenges in efficiently determining the dimensions of objects of varying shapes and sizes, particularly in confined spaces like warehouses, due to the need for static measurement locations and limited flexibility in tracking and dimensioning moving objects.

Innovation Solution

An area wide object dimensioning system that uses sensors mounted on vehicles and stationary structures to capture data from multiple perspectives, allowing for real-time determination of object dimensions, shape, volume, and orientation while the object is in motion, using radar, acoustic, and image capture systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If static measurement locations are used to determine object dimensions, then measurement accuracy is improved, but system flexibility and productivity deteriorate due to limited tracking capability of moving objects

Engineering Contradiction:
Improveobject dimension measurement accuracyVSAvoidsystem flexibility in tracking moving objects
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system transitions from static measurement locations to dynamic measurement capabilities by mounting sensors on moving vehicles (lift trucks, forklifts). This allows the measurement system to move with the object being measured, maintaining measurement capability while the object is in motion, thus resolving the contradiction between measurement accuracy and system flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Multiple sensors (cameras, LIDAR, radar) are introduced as intermediaries to capture object dimensions from various perspectives simultaneously. This intermediary approach enables accurate dimension determination of moving objects without requiring static measurement locations, as the sensors process data from multiple angles to calculate precise dimensions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple sensors are deployed to capture object data from multiple perspectives, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveobject dimension measurement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system employs multiple types of sensors (cameras, LIDAR, radar) that serve universal functions of capturing spatial and dimensional data. Each sensor type contributes different aspects of object information, and their data is integrated through control circuitry to achieve comprehensive and accurate dimension measurement, justifying the increased device complexity through enhanced measurement capability.

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

3Productivity

If objects are measured while in motion, then productivity is improved, but measurement precision deteriorates due to motion-induced measurement errors

Engineering Contradiction:
Improvewarehousing and loading operations efficiencyVSAvoidobject dimension measurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary data capture from multiple perspectives simultaneously as the object moves, rather than attempting to measure after motion stops. The control circuitry processes this multi-perspective data to calculate dimensions during motion, preventing motion-induced errors by capturing all necessary measurement data before the object changes position.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present disclosure provides an area wide object dimensioning system for an object in motion, such as mounted to a vehicle (e.g., a lift truck). One or more sensors (e.g., a radar system, an acoustic sensor, an image capture system, a LIDAR system, a microwave system, etc.) are located within the area to capture data corresponding to one or more dimensions of the object as it travels through the area. Control circuitry receives the data from the sensors, which is converted into multiple dimensions corresponding to one or more surfaces of the object. Surface dimensions are employed to determine a shape, volume, orientation, or area of the surfaces of the object, and/or the object itself, based on the multiple surface dimensions.
