Movement Path Management System for Warehouse Operator Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement path analysis systems for warehousing and shipping operations lack accuracy as they do not differentiate between movement paths based on whether an operator is carrying an object, leading to inconsistent and inaccurate data.
Innovation Solution
A movement path management system that uses location information from object-attached and operator radio communication tags to determine work status and store time-series data, allowing for the differentiation of movement paths based on whether an object is being carried, thereby enhancing analysis accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If movement path analysis is performed without differentiating work status, then the analysis process is simple, but the accuracy of the analysis result is low
Solution Approach 1:
The patent segments the operator's movement path data based on work status (carrying object vs. not carrying object). The location information acquiring means separately acquires and stores movement path data for different work statuses, enabling accurate analysis by dividing the overall movement analysis into distinct operational segments.
Solution Approach 2:
The patent introduces a determination means as an intermediary component that identifies and classifies the operator's work status based on location information. This intermediary layer processes raw location data to determine whether the operator is carrying an object, then directs the data to appropriate storage paths, resolving the contradiction between simple processing and accurate analysis.
2Measurement precision
If location information of operator and objects is continuously tracked, then movement path accuracy is improved, but system complexity and data processing load increase
Solution Approach 1:
The patent employs radio communication tags that serve multiple functions: they track location information, identify objects, and enable work status determination. This multi-functional approach improves tracking accuracy without proportionally increasing system complexity, as a single tagging system accomplishes multiple measurement tasks simultaneously.
Solution Approach 2:
The determination means automatically determines work status by analyzing location information relationships between the operator and objects without requiring manual input or additional sensors. The system self-services by using existing location data to classify operational states, reducing the complexity burden despite continuous tracking.

AI summary
A movement path management system includes location information acquiring means configured to automatically acquire location information of object-attached radio communication tags attached to each of a plurality of objects and location information of an operator's radio communication tag attached to an operator; determining means configured to determine a work status using the location information of each of the object-attached radio communication tags and the location information of the operator's radio communication tag acquired by the location information acquiring means; and processing means configured to store time-series data of the location information of the operator's radio communication tag in a memory medium along with information indicating the work status determined by the determining means.
