Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing flat products, such as touch-and-close fasteners and packaging materials, face challenges related to environmental compatibility, raw material scarcity, and inefficiencies in manufacturing processes, particularly in packaging and display solutions, where handling and recyclability are concerns.
Innovation Solution
A method and device for producing flat products that incorporate cellulose-containing components, specifically paper or cardboard, with mushroom-like shaped elements formed using shaping tools, enhancing absorbency and providing a scratching effect, and allowing for the creation of adhesive closure parts that are easy to recycle and biodegradable, using a multi-layer structure and cellulose plastic combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If plastic materials are used to produce touch-and-close fasteners and flat products, then manufacturing precision and structural integrity are improved, but environmental compatibility and recyclability deteriorate
Solution Approach 1:
The patent changes the material parameter from synthetic plastic to natural fiber composite, specifically using cellulose-containing fibers (paper or cardboard) as the base material. This parameter change maintains structural integrity through proper fiber composition and bonding while dramatically improving environmental compatibility and recyclability.
Solution Approach 2:
The patent employs composite materials by combining cellulose-containing fibers (paper or cardboard) with natural adhesives or bonding agents. This composite approach achieves the required structural integrity and manufacturing precision while using environmentally friendly, biodegradable components that replace traditional plastic materials.
2Strength
If plastic materials are used for flat products, then durability and strength are improved, but raw material availability and cost-effectiveness deteriorate
Solution Approach 1:
The patent changes the material source parameter from depleted plastic resources to abundant renewable cellulose fibers. By using paper or cardboard as the base material, the invention accesses readily available, sustainable raw materials while maintaining durability through optimized fiber composition and layer structure.
Solution Approach 2:
The patent uses homogeneous cellulose-based materials (paper or cardboard) throughout the flat product structure, ensuring consistent mechanical properties and durability. This homogeneity in material composition simplifies manufacturing and ensures reliable performance while using abundant, cost-effective raw materials.
3Stability of the object's composition
If display packaging is produced in traditional forms, then structural stability is improved, but handling efficiency and space utilization deteriorate
Solution Approach 1:
The patent segments the packaging structure into a flat, foldable configuration that can be easily handled and transported. The packaging is divided into panels and sections that can be folded along predetermined lines, maintaining structural stability when assembled while dramatically improving handling efficiency and space utilization during transport and storage.
Solution Approach 2:
The patent transitions the packaging from a three-dimensional assembled structure to a two-dimensional flat configuration for transport and storage. This dimensional change allows the packaging to be collapsed into a compact form, improving handling efficiency and space utilization, while the fold lines and structural design ensure stability when erected for display purposes.

AI summary
The method involves forming mold parts (36) using a forming tool (14), where the mold parts are an integral or separate part of a carrier (34). The tool is provided with mold cavities (16) in which the mold parts are separately formed by introducing a cellulosic suspension in the cavities such that each mold part is provided with a head part. The head part is widened in diameter compared with diameter of an arm, where the arm diameter tapers from a transitional zone to the carrier. The respective mold parts are removed by drying after partial solidification or hardening in the cavities. Independent claims are also included for the following: (1) a device for manufacturing a laminar product (2) a laminar product manufactured by a method.
