Portable Workpiece Tracking for Real-Time Manufacturing Data Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In individualized manufacturing processes, especially for wood-based workpieces, updating data sets in real-time is challenging due to variable human intervention and decoupling of production sequences, and traditional barcode identification is unreliable as labels can be removed during machining.
Innovation Solution
A method using portable devices like data goggles, tablets, or smartwatches equipped with sensors and cameras for contactless workpiece detection, updating data sets in real-time, and providing augmented reality displays for instructions and control, ensuring continuous monitoring and data synchronization across machining steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional barcode labels are used for workpiece identification, then workpiece identification is possible, but the labels can be removed or damaged during machining operations
Solution Approach 1:
The patent replaces physical barcode labels with a digital copy/representation of workpiece identification data stored in a database. The sensor unit captures workpiece characteristics (geometry, dimensions, material properties) and creates or updates a digital data set that serves as the identification medium, eliminating the need for physical labels that can be removed during machining.
2Adaptability or versatility
If manual handling and transport of workpieces between machining devices is used, then flexibility in production sequence is achieved, but the real production sequence becomes decoupled from stored workpiece data
Solution Approach 1:
The sensor unit continuously monitors workpieces during manual handling and transport operations, detecting workpiece characteristics and updating the database in real-time. This feedback mechanism ensures that the stored workpiece data remains synchronized with the actual production sequence, even when manual intervention causes variable transport times and sequences.
Solution Approach 2:
The system enables automatic detection and data updating during manual handling operations without requiring additional manual data entry or intervention. The sensor unit autonomously captures workpiece information and updates the database, allowing the system to self-correct and maintain data accuracy despite variable production sequences.
3Reliability
If individualized manufacturing with real-time data updates is implemented, then accurate workpiece-specific data is maintained, but the complexity of monitoring and updating data for each machining step increases
Solution Approach 1:
The sensor unit is designed as a multi-functional portable device that can detect various workpiece characteristics (geometric dimensions, material properties, surface characteristics) and interface with the database system. This universal device eliminates the need for separate specialized sensors for each type of measurement, reducing overall system complexity while maintaining comprehensive monitoring capabilities.

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.
