Solution Overview

Problem

Existing methods for producing paper-based cushioning or filling materials for packaging lack user-side individualization, as prefabricated paper is often printed before processing, limiting customization and precision in marking, and existing devices are not designed for user-controlled marking during production.

Innovation Solution

A method and device that allow for user-side individualization by marking the starting material or the cushioning/filling material strand before, during, or after production, using a marking device integrated into the forming process, enabling precise and customizable markings on the paper or the final product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If prefabricated paper is printed before processing into cushioning material, then the paper can be produced in advance and stored, but user-side customization and precise positioning of markings are limited

Engineering Contradiction:
Improveproduction timeVSAvoiduser customization capability
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The marking device is integrated into the forming device to perform marking actions during the cushioning material production process itself, rather than requiring separate pre-printing steps. This allows markings to be applied at the precise moment and position needed, enabling both time efficiency and user customization simultaneously

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If prefabricated paper is printed before forming into cushioning material, then production can be streamlined, but the precision and control of marking placement are reduced

Engineering Contradiction:
Improveproduction process simplicityVSAvoidmarking position precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The marking device and forming device are merged into a single integrated system. The marking device is positioned on the forming device such that markings are applied directly to the paper web during the forming process, ensuring precise positioning relative to the final cushioning material geometry while maintaining production simplicity

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a marking device is integrated into the forming device, then user-defined markings can be applied during production, but the device complexity increases

Engineering Contradiction:
Improvemarking customization capabilityVSAvoidforming device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The integrated marking device is designed to work with the existing forming device structure, utilizing the same paper web handling and positioning mechanisms. This allows the marking function to be added without requiring completely separate positioning and control systems, thereby reducing the increase in device complexity while maintaining high customization capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a method for providing a cushioning or filling material made of paper for packaging purposes, in which pre-prepared paper (12), in particular a roll (8) or a leporello stack (10), is fed to a forming device (15) as web-shaped starting material (13, 14) and in which the forming device (15) produces a strip-shaped cushioning or filling material strand (25, 26) by forming the starting material (13, 14), wherein the starting material (13, 14) is provided with a marking immediately before the production of the cushioning or filling material strand (25, 26).
