Solution Overview
Problem
Current methods for producing module strips with elevations in an electrically conductive layer are discontinuous and inefficient, lacking a continuous process for forming these elevations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a discontinuous process using a plate press is used to produce elevations in the electrically conductive layer, then the elevations can be formed with a spatially structured plate, but the production process is not continuous and efficiency is reduced
Solution Approach 1:
The patent implements a continuous lamination process where the matrix film with recesses is continuously fed through a lamination press along with the carrier layer and electrically conductive layer. This eliminates the discontinuous stopping and starting required by plate press methods, maintaining continuous production flow and significantly improving productivity while keeping the device configuration relatively simple.
Solution Approach 2:
The patent introduces a matrix film as an intermediary element that contains pre-formed recesses. This matrix film acts as a mediator that transfers the elevation pattern to the electrically conductive layer during lamination, replacing the need for complex spatially structured plates while enabling continuous processing.
2Productivity
If a spatially structured plate is used to form elevations, then the elevations can be created, but the process requires discontinuous operation and cannot be run endlessly
Solution Approach 1:
The matrix film is designed as a continuous component with recesses that can be fed endlessly through the lamination press. This allows the elevation-forming process to run continuously without interruption, eliminating the need to stop and reload plates, thereby achieving true continuous production while maintaining manufacturing simplicity.
Solution Approach 2:
The matrix film serves as a reusable intermediary carrier that brings the recess pattern into contact with the electrically conductive layer during continuous lamination. This intermediary approach simplifies the overall process by separating the pattern definition (in the matrix film) from the formation process (during lamination), enabling continuous operation.
3Productivity
If a matrix film with recesses is used in a continuous laminating press, then continuous production is enabled, but the matrix film must be precisely designed in material and thickness
Solution Approach 1:
The patent specifies precise parameters for the matrix film including thickness of 1-50 μm (preferably 3-20 μm) and controlled recess depths (1-10 μm). These parameter specifications ensure that the matrix film can be continuously processed while maintaining consistent elevation formation quality. The precise parameter control enables the continuous process to produce uniform results.
Solution Approach 2:
The matrix film as an intermediary element allows for precise control of the elevation formation process. By specifying exact thickness and recess parameters for this intermediary component, the process achieves high manufacturing precision while maintaining continuous production. The matrix film acts as a precision template that can be manufactured once and reused continuously.
4Manufacturing precision
If the electrically conductive layer is pressed into recesses of the matrix film, then elevations of predetermined dimensions are created, but the process requires precise pressure control
Solution Approach 1:
The patent specifies that the lamination press applies controlled pressure to force the electrically conductive layer into the matrix film recesses. The pressure parameters are optimized to achieve complete filling of recesses (creating precise elevation dimensions) without excessive pressure that could cause defects. This controlled pressure application enables precise elevation formation in the continuous process.
Solution Approach 2:
The matrix film recesses act as a precision template that guides the pressure application. By pressing the electrically conductive layer into these pre-defined recesses, the process achieves precise elevation dimensions with controlled pressure. The matrix film intermediary structure ensures that pressure is applied exactly where needed to form the desired elevation pattern.

AI summary
In a method for producing a module strip (200) with elevations (240) in an electrically conductive layer (230) arranged on one side of the module strip (200), first a carrier layer (220) and the electrically conductive layer (230) are provided. A stencil foil (300), which has clearances (310), is also provided. The stencil foil (300) is then fed together with the carrier layer (220) and the electrically conductive layer (230) to a continuous laminating press (100). The electrically conductive layer (230) is in this case arranged between the stencil foil (300) and the carrier layer (220). The carrier layer (220) is bonded to the electrically conductive layer (230) in the continuous laminating press (100) in a continuous process to form the module strip (200). In this process, the electrically conductive layer (230) is pressed into the clearances (310) in the stencil foil (300), whereby the desired elevations (240) are obtained in the electrically conductive layer (230).
