Sustainable Decorative Element Layering for Adhesion and Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative films used for surface design often contaminate disposal fractions due to their multi-layer composition, which includes non-recyclable materials, and fail to meet sustainability requirements while maintaining technical properties such as adhesion and appearance.
Innovation Solution
Incorporating recycled materials, renewable raw materials, biologically degradable, and marine-degradable materials into the support and cover layers of decorative elements, along with a connection layer, to enhance sustainability without compromising technical properties like adhesion and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decorative elements are made from multiple interconnected layers of different materials to fulfill adhesion and appearance requirements, then technical properties are improved, but disposal contamination increases
Solution Approach 1:
The decorative element is divided into functionally distinct layers: a support layer providing structural integrity, a decorative layer providing visual appeal, and an adhesive layer providing bonding capability. Each layer can be independently optimized and potentially separated during disposal, reducing contamination of disposal fractions.
Solution Approach 2:
The patent employs composite material structures where different materials are combined to achieve specific functions. The support layer uses materials for structural stability, the decorative layer uses materials for visual properties, and the adhesive layer uses materials for bonding, creating a composite that fulfills multiple requirements while enabling selective recycling.
2Reliability
If traditional multi-layer decorative elements are used to maintain technical properties, then adhesion and visual quality are preserved, but sustainability is compromised
Solution Approach 1:
The patent changes the material composition parameters of the decorative element layers, incorporating recyclable materials and biodegradable additives that allow the element to maintain its technical properties while improving environmental sustainability and enabling better disposal outcomes.
Solution Approach 2:
The adhesive layer is specifically designed to be separable from the support and decorative layers, enabling recovery and recycling of the valuable support and decorative layers while the adhesive layer can be disposed of separately, reducing overall environmental impact.

AI summary
A decorative element comprises a support layer and a cover layer arranged on the support layer. The decorative element comprises at least one recycled material, and/or at least one material made of renewable raw materials, and/or at least one biologically degradable and/or marine-degradable material. Component composites with at least one such decorative element arranged on a surface of the component composite are also disclosed.
