Solution Overview

Problem

Existing converting machines for corrugated board sheets lack versatility and flexibility in processing different products without extensive rebuilding, leading to high setup times and inefficiencies.

Innovation Solution

A device with a common frame housing multiple processing units on a linear guide, allowing for flexible and compact arrangement of processing units that can be adjusted automatically or semi-automatically to different products, with data transmission via cables or wireless connections for easy component addition or removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If processing units are arranged in series with fixed positions, then the machine structure is simple and stable, but the setup time increases significantly when changing products

Engineering Contradiction:
Improveproduct change capabilityVSAvoidsetup time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The machine is divided into modular processing units (printing unit, die-cutting unit, embossing unit, etc.) that can be independently positioned and configured. Each unit can be moved along the transport path and positioned at optimal locations, allowing rapid reconfiguration for different products without rebuilding the entire machine.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processing units are equipped with movable components and adjustable positioning mechanisms that allow dynamic reconfiguration during operation. The units can be moved along linear guides and positioned at different locations on the transport path, enabling flexible adaptation to different product requirements while maintaining operational efficiency.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If processing units are extensively rebuilt to manufacture different products, then product versatility is achieved, but the machine complexity and cost increase

Engineering Contradiction:
Improveproduct variety capabilityVSAvoidmachine rebuilding complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The processing units are designed with universal interfaces and standardized mounting mechanisms that allow the same unit to perform multiple functions across different products. The common frame and linear guide system provide a universal platform that accommodates various processing units without requiring extensive structural modifications, reducing machine complexity while maintaining versatility.

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

3Area of stationary object

If processing units are positioned far apart to accommodate long travel distances, then each unit has sufficient working space, but the positioning accuracy and setup time deteriorate

Engineering Contradiction:
Improveunit working spaceVSAvoidpositioning accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The positioning system incorporates electronic control and detection devices that replace purely mechanical positioning methods. Sensors and control systems monitor the position of processing units along the linear guides, enabling precise positioning even when units are spaced apart. This electronic feedback mechanism maintains positioning accuracy while allowing adequate working space between units.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
