Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing workpieces from material plates are complex and costly due to the need for additional equipment and time-consuming repositioning and fastening steps after cutting, which increases manufacturing time and complexity.
Innovation Solution
A method involving the application of metallization to the material plate followed by galvanic deposition of a carrier layer, allowing for efficient laser cutting and subsequent processing on the same carrier, with the workpieces remaining attached for further processing and easy removal later.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If workpieces are cut out from material plate and then repositioned on carrier for further processing, then further processing can be performed, but additional time and equipment are required increasing manufacturing complexity and cost
Solution Approach 1:
The material plate is attached to the carrier before laser cutting, so that the workpieces remain in position during subsequent processing steps. This preliminary attachment eliminates the need for repositioning operations after cutting, reducing manufacturing time and simplifying the overall process.
Solution Approach 2:
The cutting process and further processing steps are merged into a single continuous operation by keeping the workpieces on the carrier throughout. The carrier serves as both the support during cutting and the fixture for subsequent processing, eliminating the need for separate repositioning operations.
2Adaptability or versatility
If additional equipment is used for positioning and fastening workpieces on carrier, then workpieces can be processed further, but system complexity and space requirements increase
Solution Approach 1:
The carrier is designed to serve multiple functions: it supports the material plate during laser cutting, holds the workpieces in position during further processing, and provides a stable base for the entire operation. This multi-functionality eliminates the need for separate positioning and fastening equipment.
Solution Approach 2:
The positioning and fastening functions are extracted from separate equipment and integrated into the carrier itself. The carrier structure includes integrated features for holding the material plate and maintaining workpiece positions, removing the need for additional positioning devices.
3Stability of the object's composition
If material plate is fastened to carrier before cutting, then workpieces remain in position for processing, but attachment method must be efficient and automated
Solution Approach 1:
The attachment method replaces complex mechanical fastening systems with a simpler process. The material plate is attached to the carrier using a method that can be easily automated, such as adhesive application or mechanical clamping, providing stable positioning without requiring complex automated attachment equipment.

AI summary
The invention relates to a method and a system for producing and further processing workpieces from a material sheet (2) using a laser (6). As a first step, the material sheet is mounted on a carrier (5). Subsequently, the individual workpieces (1) are cut out of the material sheet using a laser (6). The workpieces remain attached to the carrier (3) and can then be further processed, for example, coated. After further processing, the workpieces are removed from the carrier (5). The material sheet (2) is mounted on the carrier (5) by applying a metallization (3) to the material sheet (2) and electroplating a carrier layer (5) onto the metallization (3). Since the workpieces remain on the carrier (5) after cutting, they do not need to be individually repositioned for further processing.A system which produces workpieces according to the inventive method can transport and position the carrier (5) as a whole.
