Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If milling technology is used to separate metal cards from metal sheets, then separation precision can be achieved, but the production time increases and cost increases
Solution Approach 1:
The patent replaces the mechanical milling system with a hybrid system combining optical detection and stamping. Position markings are optically detected to locate card positions, then a stamping device performs rapid separation. This substitution eliminates the time-consuming milling process while maintaining precision through optical positioning, directly resolving the contradiction between separation precision and production efficiency.
2Manufacturing precision
If milling technology is used to separate metal cards from metal sheets, then separation can be performed, but the production cost increases
Solution Approach 1:
The patent replaces expensive milling operations with a more economical stamping process. The optical detection system provides precise positioning information, enabling the stamping device to accurately separate cards without the need for costly milling equipment and extended processing time. This substitution significantly reduces production costs while maintaining separation capability.
3Productivity
If position markings are introduced and optical detection is used, then separation speed increases, but the process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-introducing position markings into the metal sheet before the separation process. These markings serve as reference points that enable rapid optical detection and positioning. By preparing the workpiece in advance with these markings, the actual separation operation can proceed quickly using simple stamping, thus increasing separation speed while the added complexity of marking introduction is offset by the simplicity of the subsequent stamping process.

AI summary
A method for producing a card element. In a step, a first material layer having a predefined card body and at least one position marking is provided. In a step, a second material layer having at least one recess extending through the second material layer is provided. In a step, the second material layer is applied onto the first material layer in such a way that the position marking in the first material layer can be optically detected through the recess extending through the second material layer. In a step, a separating device is aligned on the basis of an optically detected location of the position marking. In a step, the predefined card body is separated from the first material layer by means of the separating device so as to produce the card element.
