Solution Overview
Problem
In the machining of wood or wood materials, existing methods face challenges with label carriers being lost or damaged, requiring additional apparatus and not allowing for dynamic adjustment to changing workpiece dimensions, leading to potential machining errors and inefficiencies.
Innovation Solution
A method and device that identify workpieces based on their inherent properties, using a single detection system for both identification and quality checking, allowing for dynamic machining adjustments and eliminating the need for label carriers by detecting geometric and physical properties before and after machining steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If label carriers are applied to the surface of workpieces for identification, then workpiece identification is enabled, but the label carriers may be lost or damaged during machining and require additional removal steps
Solution Approach 1:
The workpiece itself serves as the identification carrier through its inherent geometric and physical properties (dimensions, weight, color) rather than requiring external label carriers. The detection system reads these self-existent properties directly from the workpiece, eliminating the need for separate labeling apparatus and reducing the risk of label loss or damage during machining operations
Solution Approach 2:
The identification function is extracted from external label carriers and integrated into the workpiece's inherent properties. By detecting geometric dimensions, weight, and color directly from the workpiece itself, the system removes the need for separate labeling components and their associated application and removal apparatus
2Reliability
If label carriers are used for workpiece identification, then unique identification is achieved, but additional measures in terms of apparatus are required for application and detection
Solution Approach 1:
The detection system serves multiple functions: it detects geometric properties for identification, measures physical properties like weight and color, and monitors workpiece dimensions for quality control. This multi-functional approach eliminates the need for separate labeling and detection apparatus, reducing overall system complexity while maintaining reliable workpiece identification
Solution Approach 2:
The workpiece's inherent properties (geometric dimensions, weight, color) serve as the identification medium, requiring no external labeling apparatus. The detection system directly reads these self-existent properties, eliminating the need for label application equipment and reducing apparatus outlay
3Adaptability or versatility
If workpiece dimensions change due to external influences, then workpiece properties vary, but imprecise positioning in machine tools leads to incorrect machining
Solution Approach 1:
The detection system measures the actual geometric and physical properties of each workpiece before machining and provides feedback to the control system. Based on this feedback, the control system automatically adjusts machining parameters and tool positioning to compensate for dimensional variations, ensuring precise machining despite changes in workpiece properties due to external influences like temperature
Solution Approach 2:
The machining process is made dynamic by continuously detecting workpiece properties and adjusting machining parameters in real-time. The system adapts to each workpiece's actual dimensions and characteristics, allowing precise machining even when workpiece properties vary due to external environmental factors
4Device complexity
If a single detection system is used for both workpiece identification and quality checking, then apparatus outlay is reduced, but the system must handle multiple functions
Solution Approach 1:
The detection system is designed with multi-functionality, using the same sensors and detection mechanisms to perform both workpiece identification through geometric properties and quality checking through physical property measurement. This universal system reduces apparatus outlay while maintaining the capability to handle multiple detection functions through integrated software and control algorithms

AI summary
The invention relates to a method for identifying workpieces, which preferably consist at least partly of wood, wood materials or the like, in a machining process, having the steps of: detecting at least one workpiece property prior to a machining step, uniquely assigning a workpiece category to the workpiece using the at least one detected workpiece property, and machining the workpiece in the machining step which is determined by the assigned workpiece category of the workpiece.
