Portable Workpiece Tracking for Real-Time Manufacturing Data Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In individualized manufacturing processes, especially for wood-based workpieces, updating data records in real-time is challenging due to variable handling and transport by employees, decoupling the actual production process from stored data, and existing identification methods like barcodes are prone to removal or are undesirable.
Innovation Solution
A method using a portable device, such as data glasses with a sensor unit and a 3D camera, for real-time detection and data transmission to a database, allowing for continuous updating of workpiece-specific data records during processing and handling steps, enabling accurate tracking and monitoring without contact and providing augmented reality instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If barcodes or labels are used to mark workpieces for identification, then workpiece identification is enabled, but the labels can be removed or removed during processing
Solution Approach 1:
The patent replaces mechanical/physical labeling methods (barcodes, stickers) with optical sensing methods. The sensor unit captures images of workpieces and identifies them through image recognition algorithms, eliminating the need for physical labels that can be removed during processing.
Solution Approach 2:
The system creates a digital copy (image) of the workpiece surface that contains identification information. Instead of attaching a physical label, the workpiece itself is used as the carrier of identification data through naturally present markings, textures, or patterns that are captured and stored as digital images.
2Adaptability or versatility
If manual handling and transport of workpieces between processing machines is used, then flexibility in individualized manufacturing is achieved, but the production flow becomes decoupled from stored data
Solution Approach 1:
The sensor unit continuously captures workpiece images at various stages of manufacturing and feeds this information back to the database system. This real-time feedback mechanism ensures that the stored data remains synchronized with the actual production flow, even when manual handling causes variable sequences and timing.
Solution Approach 2:
The system enables automatic identification and data capture without requiring manual data entry or intervention. The sensor unit autonomously captures workpiece images and the system automatically updates the database, allowing the manufacturing process to self-document despite manual handling variations.
3Measurement precision
If real-time data updates during machining operations are implemented, then data accuracy is improved, but the complexity of the monitoring system increases
Solution Approach 1:
The sensor unit serves multiple functions: it captures workpiece images for identification, monitors machining operations, tracks workpiece movement, and provides data for quality control. This multi-functionality reduces the need for separate specialized devices, thereby limiting the increase in overall system complexity while maintaining high data accuracy.

AI summary
The present invention relates to a method for monitoring a manufacturing process, comprising the steps of: detecting a workpiece with a sensor unit of a portable device, sending the information acquired by the sensor unit to a database and applying a workpiece-specific data set, detecting the workpiece before, during and/or after carrying out a machining step or a handling step on the workpiece by the sensor unit of the portable device, updating the data set stored in the database before, during and/or after carrying out a machining step or handling step on the workpiece. The manufacturing process can, for example, relate to the machining of a board-shaped workpiece, such as a solid wooden board, a chipboard, a MDF board, a HDF board, or a workpiece made of another wood material.
