Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to efficiently print electronic structures on elastomeric substrates with non-uniform or non-planar surfaces, such as vulcanized rubber, due to surface roughness and poor wettability, making it difficult to achieve good printing results, especially on three-dimensional surfaces.
Innovation Solution
A method involving a planar foil with a printable surface, where a structure is printed onto the foil, and then laminated onto an elastomer substrate using heat and pressure, allowing for adaptation to three-dimensional shapes without the need for additional adhesion layers, enabling direct bonding and versatile applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If direct printing is attempted on vulcanized rubber substrates, then printing can be performed on elastomeric surfaces, but the non-uniform surface properties, surface roughness, and poor wettability result in poor printing quality
Solution Approach 1:
The process is segmented into two independent stages: first printing the electronic structure on a planar foil with uniform properties, then separately bonding this pre-printed foil to the elastomeric substrate. This segmentation allows each stage to be optimized independently, avoiding the conflict between printing quality and substrate elasticity.
Solution Approach 2:
A planar foil acts as an intermediary carrier between the printing process and the elastomeric substrate. The foil provides a suitable planar surface for high-quality printing while serving as a mediator that can be subsequently bonded to the three-dimensional elastomeric surface, decoupling the printing requirements from the substrate properties.
2Adaptability or versatility
If printing is performed on three-dimensional elastomeric surfaces, then electronic structures can be applied directly to the component, but the process becomes extremely difficult and slow
Solution Approach 1:
The electronic structure is printed in advance on a planar foil before being transferred to the elastomeric substrate. This preliminary action on a flat surface dramatically simplifies the printing process and increases speed, while the subsequent bonding step accommodates the three-dimensional geometry of the final component.
3Strength
If additional adhesion layers are used to improve bonding on elastomeric substrates, then bonding strength may be improved, but the process complexity and manufacturing steps increase
Solution Approach 1:
The bonding process utilizes parameter changes (heat and pressure application) to activate the thermoplastic material in the foil, enabling direct bonding to the elastomeric substrate without additional adhesion layers. This approach maintains bonding strength while simplifying the overall process by eliminating intermediate layers.

AI summary
A method for producing an elastomeric component, preferably an elastomeric sealing component, including an elastomer body and a printed structure, preferably a printed electronic structure or circuit, on a surface of the elastomer body. The method includes: a. providing a planar foil of thermoplastic material having a printable surface; b. printing a structure onto the printable surface to obtain the printed structure; c. providing an elastomer substrate for forming the elastomer body; d. placing the planar foil with the printed structure onto the elastomer substrate; and e. laminating the combined planar foil and elastomer substrate by applying heat and pressure. The elastomeric component is obtained in that the elastomer substrate is formed to the shape of the elastomer body before step d); the elastomer substrate is formed to the shape of the elastomer body during lamination; or the elastomer substrate is formed to the shape of the elastomer body after lamination.
