Solution Overview
Problem
Manufacturing two-layer composites for vehicle interiors, especially with expensive decorative layers like high-quality leather, faces challenges such as high scrap rates and difficulty in precisely aligning and fixing the layers during production.
Innovation Solution
A method and system using templates with cutouts and a tablet with adhesive to precisely position and attach the layers, allowing for efficient alignment and connection of the composite layers, with optional modular design and positioning elements for adaptability and automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual alignment methods are used for layer assembly, then flexibility in handling different materials is maintained, but manufacturing precision and alignment accuracy deteriorate
Solution Approach 1:
The patent introduces templates as intermediary tools with precisely engineered cutouts that mediate between the layers during assembly. These templates serve as positioning fixtures that guide the placement of expensive decorative layers and spacer fabrics, ensuring accurate alignment without requiring complex automated positioning systems. The templates act as a simple yet effective mediator that achieves high manufacturing precision through their geometric design rather than through complex active control mechanisms.
2Reliability
If expensive decorative layers are used, then product quality is improved, but scrap loss increases due to manufacturing difficulties
Solution Approach 1:
The patent applies preliminary action by pre-trimming the layers to match the contours of the template cutouts before assembly. This preliminary preparation ensures that when the layers are placed in the templates, they fit precisely without requiring excessive material for later trimming or adjustment. The layers are pre-shaped to conform to the template geometry, which minimizes material waste and reduces scrap loss while maintaining the high quality of expensive decorative materials.
3Manufacturing precision
If layers are trimmed to fit cutouts, then manufacturing precision is improved, but additional processing time is required
Solution Approach 1:
The patent performs the trimming operation as a preliminary action before assembly, rather than as a corrective step during or after assembly. By pre-trimming layers to match template cutout contours beforehand, the process eliminates the need for time-consuming adjustments and repositioning during the assembly phase. This preliminary preparation, while requiring initial trimming time, actually reduces total manufacturing time by enabling direct, precise placement without iterative adjustments.

Function Achieved in This Case
Enables simple, efficient, and precise manufacturing of two-layer composites with reduced scrap and improved alignment, allowing for precise positioning and attachment of layers, even with varying shapes and materials, and facilitates easy adaptation to changes in layer dimensions over time.
Implementation Method 1
a tablet provided with an adhesive is disposed on the first layer disposed in the cutout, such that the first layer adheres to the tablet

AI summary
A method for manufacturing a composite includes providing a first template including a cutout for a first layer of the composite, disposing the first layer in the cutout, and disposing a tablet, provided with an adhesive, on the first layer such that the first layer adheres to the tablet. Next, the tablet is removed, together with the first layer adhered thereto, from the cutout, and an adhesive is applied to a side of the first layer facing away from the tablet. A second template is provided that includes a cutout for a second layer of the composite, and then the second layer is disposed in the cutout. The tablet, together with the first layer adhered thereto, is disposed on the second layer disposed in the cutout of the second template, and the tablet is removed, together with the composite produced from the first and second layers, from the second template.
