Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current warehouse management systems cannot effectively assess the efficiency of workers performing collection tasks, particularly for workers unfamiliar with their surroundings, leading to inefficiencies and distractions.
Innovation Solution
A work management system incorporating 3D sensors to measure depth data, a movement data generation unit to recognize worker positions, an identification unit to match worker data with movement data using time as a key, and an association unit to link movement data with work data, enabling the assessment of work efficiency and quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D sensors are installed to measure worker movement and assess work efficiency, then work efficiency assessment capability is improved, but device complexity and installation cost increase
Solution Approach 1:
The 3D sensor system is designed to perform multiple functions: it not only measures worker positions and movements but also tracks article locations and monitors warehouse environment. This multi-functionality reduces the need for separate detection devices for each purpose, thereby improving measurement precision while limiting the increase in device complexity
Solution Approach 2:
The system uses existing warehouse infrastructure (such as ceiling-mounted positions) to install 3D sensors, leveraging the current spatial structure. The sensors automatically capture depth data and the system self-calibrates using the workspace geometry, reducing installation complexity and the need for extensive additional detection devices
2Loss of information
If 3D sensors are deployed to track worker positions and movements, then work efficiency recognition is improved, but installation cost and system complexity increase
Solution Approach 1:
The system combines depth data acquisition, position recognition, movement tracking, and work efficiency calculation into a single integrated system. The 3D sensors capture spatial information that is processed through multiple functional units (depth data acquisition unit, position recognition unit, movement data generation unit) that work together, thereby improving information completeness while managing system complexity through functional integration
Solution Approach 2:
The system transitions from traditional 2D monitoring to 3D spatial tracking using depth data from 3D sensors. This dimensional enhancement allows comprehensive capture of worker movements and positions without requiring multiple separate detection devices, improving information accuracy while controlling installation complexity

Function Achieved in This Case
Enables the recognition and analysis of work efficiency and quantity for each worker, reducing inefficiencies and distractions by associating movement data with work data, without the need for extensive installation of detection devices or worker-specific communication devices.
Implementation Method 1
one or a plurality of 3D sensors configured to measure a depth of an object so as to include the area in a measurement range at least during a period during which the work data is recorded, and thereby acquire depth data including time
Data Source
AI summary
A work management system inputs work data for an area and articles to be managed by a warehouse management system. The work management system makes one or a plurality of 3D sensor to measure a depth of an object so as to include the area in a measurement range at least during a period during which the work data is recorded, and thereby acquires depth data including time. The work management system recognizes a position of an arbitrary person and time at the position from the depth data and generate movement data based on a result of the recognition. The work management system matches, based on both of the data, the arbitrary person with the worker by using the time as a key, and thereby identifies the arbitrary person. The work management system associates both of the data for the identified worker.
