Release Fleece Enables Structuring Layer Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing matrices for structuring building surfaces often require significant disposal effort as they are typically discarded together with different material components, necessitating separate disposal and treatment.
Innovation Solution
Incorporating an inner adhesive layer and a release fleece between the structuring and adhesive layers allows for easy detachment of the structuring layer from the support part, enabling separate disposal and reuse of components, with both layers made of polyurethane materials for simplified handling, and optionally including an RFID chip for data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the matrix is used to structure building surfaces multiple times, then the structuring function is maintained, but the disposal effort increases due to different material compositions requiring separate handling
Solution Approach 1:
The matrix is divided into separable components: a support part and a structuring layer connected by an adhesive layer with release fleece. This segmentation allows the structuring layer to be detached and reused with different support parts, reducing disposal effort while maintaining usage duration.
Solution Approach 2:
The release fleece enables easy separation of the structuring layer from the support part, allowing the valuable structuring layer to be recovered and reused while the support part can be discarded or reused separately, optimizing disposal effort based on material composition.
2Stability of the object's composition
If the structuring layer is firmly bonded to the support part, then structural stability is improved, but separation and reuse become difficult
Solution Approach 1:
A release fleece is introduced as an intermediary layer between the adhesive layer and the structuring layer. This intermediary provides controlled adhesion: strong bonding during use for structural stability, but easy separation when needed for reuse, resolving the contradiction between stability and separation ease.
Solution Approach 2:
The adhesive connection is made dynamic through the release fleece, allowing the bond strength to change from strong (during operation) to weak (during separation). This dynamic property enables both firm bonding for stability and easy separation for reuse.
3Reliability
If different materials are used for the structuring layer and adhesive layer, then functional performance is optimized, but disposal complexity increases
Solution Approach 1:
By segmenting the matrix into separable components with the release fleece, different materials can be used for optimal functional performance in each layer, while the separation capability ensures that disposal complexity is managed through selective removal and recycling of valuable components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces disposal effort by allowing separate treatment of materials and potential reuse of the support part, with permanent three-dimensional structures and simplified material handling due to similar polyurethane compositions, while enabling data access for quality assurance.
Implementation Method 1
an adhesive layer which is arranged between the structuring layer of the matrix and a support part, e.g. a carrier plate, a formwork base or a production table, and by means of which the matrix can be connected to the support part
Implementation Method 2
a release fleece arranged between the inner adhesive layer and the adhesive layer of the matrix. After the intended use of the matrix for structuring building surfaces, it is easy to detach the matrix with its structuring layer from the support part, since the release fleece provided in the matrix according to the invention facilitates the easy separation

AI summary
A matrix (1) for structuring building surfaces has a structuring layer (2) by means of which a building surface can be designed with a three-dimensional structure, and an adhesive layer (5) which is arranged between the structuring layer (2) of the matrix (1) and a support element (6), e.g., a carrier plate, a formwork base, or a production table, and by means of which the matrix (1) can be connected to the support element (6). In order to facilitate the disposal of the matrix (1) and, if applicable, the disposal of the support element (6) with less effort after its intended use, it is proposed that the matrix (1) has an inner adhesive layer (3) arranged between the structuring layer (2) and the adhesive layer (5) of the matrix (1), and a release fleece (4) arranged between the inner adhesive layer (3) and the adhesive layer (5) of the matrix (1).
