Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in creating a method to securely, compactly, and easily insert multi-part patient information into pharmaceutical product packaging while ensuring high safety and ease of handling, as existing solutions face issues with misassembly, space constraints, and mechanical insertion difficulties.
Innovation Solution
A method involving a single printed sheet with longitudinal and transverse folds, adhesive application, and perforations to create detachable book-like parts that can be compactly folded and securely inserted, with additional steps for further compaction and closure using an adhesive label, ensuring secure and user-friendly handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single printed sheet is folded multiple times to create a compact package insert, then the compactness and space utilization improve, but the ease of handling and user comprehension deteriorate due to confusion and difficulty in unfolding
Solution Approach 1:
The printed sheet is divided into multiple detachable book-like parts through perforations, allowing users to separate and handle individual sections easily while maintaining compactness when assembled. The perforations enable clean separation without damaging the overall structure.
Solution Approach 2:
The patent transforms the traditional flat folded insert into a three-dimensional book-like structure with multiple detachable parts. This dimensional transformation allows the insert to be compact when assembled but easily separable and handleable when opened, resolving the contradiction between compactness and ease of handling.
2Reliability
If intensive monitoring such as camera monitoring is used to prevent misassembly of printed sheets, then the reliability improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The printed sheet design inherently prevents misassembly through its self-explanatory book-like structure with detachable parts. The perforations and adhesive bonds create a structure that naturally guides correct assembly without requiring external monitoring systems, making the system self-checking and foolproof.
3Quantity of substance
If multiple information media are attached to pharmaceutical products to meet regulatory requirements, then the completeness of information improves, but the ease of insertion into product packaging deteriorates due to space constraints and mechanical difficulties
Solution Approach 1:
Multiple information media are merged into a single integrated printed sheet that is then folded into book-like parts. This consolidation allows all required information to be provided in one compact unit that can be easily inserted into product packaging as a single item, eliminating the difficulties of handling multiple separate media.
Solution Approach 2:
The book-like parts with detachable sections allow information to be nested within a compact structure. The perforated sections can be separated and nested within each other or within the product packaging, maximizing space utilization while maintaining ease of insertion.

Implementation Method 1
applying at least two adhesive tracks running in the longitudinal direction or at least one adhesive area on one or both sides of the printed sheet; making at least one longitudinal folds in such a way that the interaction of the adhesive tracks or the at least one adhesive area forms adhesive bonds connecting at least two printed sheet areas placed one on top of the other

AI summary
The invention relates to a method for producing a printed product, in particular a multi-part package leaflet for a pharmaceutical product, from a single printed sheet (40) having a longitudinal side and a transverse side, comprising the steps of: applying adhesive traces (44a-d) to one or both sides of the printed sheet (40), making one or more longitudinal folds such that, by the interaction of the adhesive traces (44a-d), at least four superimposed printed sheet areas are bonded together;The process involves introducing at least two perforations (42a, 42b) into the printed sheet (40) in the longitudinal direction, applying further adhesive (48a, 48b), making a transverse fold and gluing the two transversely folded parts together in such a way that the number of pages of the printed product resulting from the final product is doubled, and trimming the printed sheet (40) thus processed, wherein the correspondingly processed product in a long state has at least two consecutive parts (46a, 46b) which are separably connected to each other at at least one perforation (54), wherein each part (46a, 46b) is bound in a book-like manner by the gluing in the detached state. To achieve a packaging state, this product in its long state is then folded crosswise – possibly several times – and provided with a perforated adhesive label (48) so that the product can be inserted into a folding carton packaging without interference.
