Solution Overview

Problem

Existing edging stands face challenges in achieving precise translational guidance of the edging roller without tilting, due to mismatched forces from piston-cylinder and balancing cylinders, leading to imprecise adjustments during rolling operations.

Innovation Solution

A device with balancing cylinders and an adjusting cylinder, where the compressive force from the adjusting cylinder intersects or runs adjacent to the articulation of the balancing cylinder, ensuring no tilting moment is exerted on the bearing device, allowing for high-precision linear movement of the edging roller.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the piston of the piston-cylinder unit is positioned at a distance from the balancing cylinders, then the structure allows for easier assembly and maintenance, but the cassette is not guided in an exactly translatory manner, resulting in imprecise adjustment of the edging roller

Engineering Contradiction:
Improveassembly and maintenance easeVSAvoidadjustment precision of edging roller
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

A guiding device is introduced as an intermediary component between the piston-cylinder unit and the balancing cylinders. This guiding device ensures that the cassette moves in an exactly translatory manner during adjustment, eliminating imprecision while maintaining the structural separation that facilitates assembly and maintenance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the forces from the piston-cylinder unit and balancing cylinders are not precisely matched, then the structure allows for greater flexibility in force distribution, but the cassette experiences tilting moments, resulting in imprecise adjustment

Engineering Contradiction:
Improveforce distribution flexibilityVSAvoidadjustment precision of edging roller
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The guiding device acts as a mediator that prevents tilting moments from affecting the cassette movement. It ensures that even when forces from the piston-cylinder unit and balancing cylinders are not precisely matched, the cassette is guided in a purely translatory manner without tilting, thus maintaining adjustment precision while preserving force distribution flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a massive cassette is used for storing the edging roll, then the structure provides stable support for the roll, but it takes up a large amount of space and allows play against the roll, reducing adjustment precision

Engineering Contradiction:
Improvesupport stability for rolling stockVSAvoidadjustment precision of edging roller
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The guiding device serves as an intermediary that eliminates play between the cassette and the edging roll. It ensures that the massive cassette, which provides stable support, moves precisely without any lateral play or deviation, thereby achieving both stable support and high adjustment precision simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Manufacturing precision

If balancing cylinders are used to pull the cassette in the opposite direction, then play between components is reduced, but the complexity of the device increases due to additional components and force balancing requirements

Engineering Contradiction:
Improvejoint play reductionVSAvoiddevice structural complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The guiding device is introduced as a relatively simple intermediary component that works in conjunction with the existing balancing cylinders. It reduces joint play and ensures precise translatory movement without requiring a complete redesign of the force balancing system, thus improving precision while adding minimal structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
