Printed Product Collection Wrapping Without Adhesives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing collections of printed products require additional materials and equipment, leading to increased costs and resource utilization.
Innovation Solution
A method where printed products are formed into an intermediate stack and wrapped using one of the products as a packaging element, eliminating the need for additional materials by bending and positioning the packaging element around the stack using a wrapping device with movable elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive strips or adhesive points are used to hold the collection of printed products together, then the stacks are held together effectively, but additional materials and costs are required
Solution Approach 1:
One of the printed products itself is used as the packaging element to wrap and hold the stack together, eliminating the need for separate adhesive strips or points. The printed product serves dual purposes: as content and as packaging material.
Solution Approach 2:
The printed product is given multiple functions: it serves as both the informational/advertising content and as the packaging material to hold the collection together. This multi-functionality eliminates the need for separate packaging materials.
2Stability of the object's composition
If a special packaging sheet is used to wrap the stack of printed products, then the collection is held together effectively, but additional materials and stocking requirements are created
Solution Approach 1:
The printed products within the collection serve their own packaging function by providing a sheet that wraps around the stack. This eliminates the need for external special packaging sheets and their associated stocking requirements.
Solution Approach 2:
Instead of using separate packaging material that would be discarded, one of the printed products is converted into packaging material, effectively recovering and repurposing existing material within the system.
3Quantity of substance
If one printed product is opened and remaining printed products are inserted into it, then the collection is formed without additional packaging materials, but a considerable amount of equipment is required for insertion
Solution Approach 1:
Instead of inserting printed products into an opened printed product as suggested in prior art, the invention inverts the approach by wrapping a printed product around the stack. This reversal eliminates the need for complex insertion equipment while still achieving material-free packaging.
Solution Approach 2:
The solution uses a dynamic wrapping process where the packaging element is bent and folded around the stack, rather than requiring static insertion mechanisms. This dynamic approach simplifies the equipment needed.
4Stability of the object's composition
If adhesive or non-adhesive strips are placed laterally around an edge of the collection, then the stack is held together, but additional expense is incurred due to provision of strips
Solution Approach 1:
The printed products themselves provide the holding function through wrapping, eliminating the need for separate strips. The system serves its own packaging needs using its own components.
Solution Approach 2:
The invention extracts the packaging function from separate strips and integrates it into the printed products themselves, removing the need for additional strip provision and reducing manufacturing complexity.

AI summary
The invention relates to a method for producing collections (15) from a plurality of N (N=2, 3, 4, . . . ) different printed products (11a-d), which collections (15) each comprise a stack (13) of printed products (11a-c), which stack is packed in a packaging element (11d) wrapped around the stack (13). A solution that does not require additional material use includes the following steps: providing the N printed products (11a-d): forming an intermediate stack (13) from N−x (x=1, 2, 3, . . . ) of the N printed products (10a-d); providing the x remaining printed products as a packaging element (11d); and wrapping the intermediate stack (13) in the packaging element (11d).
