Solution Overview

Problem

Existing media coupling systems for roll stands require additional actuators and separate control systems for coupling and locking movements, leading to increased equipment and operational complexity, as well as an unchangeable vertical distance between the media coupling and locking element.

Innovation Solution

The media coupling system integrates the locking device's actuator to perform both locking and coupling movements, allowing for synchronous operation and reducing the need for a separate control system, with a vertically displaceable coupling element carrier enabling adjustable vertical movement during coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a separate actuator is added to the locking device to execute coupling movement, then the coupling process can be automated, but the device complexity and equipment outlay increase

Engineering Contradiction:
Improveautomatic coupling processVSAvoidadditional control elements
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines the coupling movement execution with the existing locking device's actuator. The single actuator is designed to perform both locking and coupling functions through integrated actuating gears, eliminating the need for separate actuators and control systems while maintaining full automation capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking device's actuator is designed with multi-functionality to execute both locking movements and coupling movements. By making the actuator universal, the system avoids additional equipment outlay and control complexity while achieving complete automation of the coupling process

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

2Device complexity

If the vertical distance between media coupling and locking element is fixed, then the locking device structure is simplified, but the coupling process cannot accommodate roll gap adjustments

Engineering Contradiction:
Improvelocking device structureVSAvoidvertical movement capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a vertically displaceable coupling element carrier that can move along the locking element's travel path. This dynamic arrangement allows the coupling element to be positioned at different vertical locations during the locking process, enabling both roll gap adjustments and maintaining a relatively simple locking device structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling element is separated from the locking element and placed on a independently displaceable carrier. This segmentation allows the coupling element to move vertically relative to the locking element while the locking device structure remains relatively simple, providing adaptability for different roll gap requirements

Inventive Principle:
Principle #1Segmentation
