Foamed Polyolefin Panel Imagery via Dye-Sublimation Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for printing on foamed polyolefin products, such as EVA or PE foam, result in low continuity and intensity of images due to broken cell surfaces, making direct printing ineffective, and existing solutions like laser etching or multi-colored layers are costly and lack durability, while also posing safety risks in industries like aviation due to component misplacement in kitting trays.
Innovation Solution
A method involving dye-sublimation printing on a carrier medium, which is then adhered to the polyolefin article using hot pressing, allowing for vibrant and durable imagery on polyolefin products and kitting trays, ensuring accurate component identification through aligned images on compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If direct printing techniques (screen-printing) are used on foamed polyolefin products, then branding and imagery can be added, but the printed image has low continuity and low intensity due to broken cell surfaces forming pits
Solution Approach 1:
The patent introduces a liquid carrier as an intermediary substance that penetrates the porous foam structure and delivers pigment throughout the material. The carrier allows the pigment to distribute evenly within the foam cells, creating a continuous and intense image that overcomes the broken cell surface problem inherent in direct printing on foamed polyolefin.
Solution Approach 2:
The patent exploits the porous structure of foamed polyolefin by using a liquid carrier that can penetrate and distribute pigment throughout the foam's cellular structure. This approach transforms the previously harmful porous nature into a beneficial feature, allowing the pigment to fill and color the internal cell structure, thereby achieving high image continuity and intensity.
2Ease of manufacture
If laser etching or heat embossing is used to improve branding on polyolefin products, then branding capability is enhanced, but the methods are not cost effective and lack durability
Solution Approach 1:
The patent replaces mechanical processes (laser etching, heat embossing) with a chemical/physical process involving liquid carrier and pigment penetration. This substitution eliminates the need for expensive equipment and complex multi-step mechanical processes, achieving cost-effective and durable branding through a simpler, more direct method that integrates coloring and branding in one operation.
3Ease of manufacture
If multi coloured layers are used and cut to shape for swimming floats, then branding and imagery can be achieved, but the methods are not cost effective and lack durability
Solution Approach 1:
The patent applies pigment and liquid carrier to the foam material before cutting and shaping operations. This preliminary coloring action eliminates the need for subsequent coloring or branding operations on cut pieces, reducing manufacturing complexity and cost. The entire product can be colored and branded in one operation before final shaping, rather than requiring multiple operations on individual components.
4Ease of manufacture
If conventional printing processes are used on flight case panels, then branding potential is improved, but the processes suffer from poor durability and require large volumes of product to be cost effective
Solution Approach 1:
The patent utilizes the porous structure of the flight case panel material to allow liquid carrier and pigment penetration. This creates durable branding by embedding the pigment within the material's cellular structure rather than applying a surface coating that can peel or fade. The porous absorption mechanism ensures deep, permanent coloration that maintains durability.

AI summary
A method of manufacturing a polyolefin product is disclosed. The method includes the steps of printing an image on a transfer medium, hot pressing a carrier medium (such as a textile or wood product) and the transfer medium such that the image is transferred to the carrier medium, and adhering the carrier medium to a first polyolefin article to produce a polyolefin product. The polyolefin product may then be subject to further processes, such as cutting, thermoforming, etc. into its desired form. An improved method of producing polyolefin products having colorful imagery thereon is provided. A method of manufacturing a case is also disclosed, including printing an image on a transfer medium, hot pressing a carrier medium and the transfer medium such that the image is transferred to a first side of the carrier medium, and assembling a case, wherein a panel for the case includes the carrier medium.
