Solution Overview

Problem

Conventional turning devices for large diameter pipes lack adequate load-bearing capacity, leading to potential damage and deformation during coating processes, and are often designed for specific pipe diameters, requiring multiple devices for different sizes.

Innovation Solution

A turning device with a base body and two supporting devices, each comprising pivotable rocker elements and rollers that adapt to different pipe diameters by pivoting about multiple axes, ensuring even distribution of weight and minimizing contact points to prevent deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional turning devices are used to support large diameter pipes, then the pipes can be turned during coating processes, but the pipes risk indentation and damage due to inadequate load-bearing capacity and excessive stresses

Engineering Contradiction:
Improvedamage-free pipe turningVSAvoidload-bearing capacity
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The turning device employs rocker elements that can pivot about multiple axes (first pivot axis and second pivot axis) to dynamically adapt to different pipe diameters and weight distributions. This dynamic adjustment capability allows the device to optimize its load-bearing configuration for each specific pipe, ensuring adequate support without excessive stresses that could cause damage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device changes its geometric parameters by allowing the rocker elements to pivot about multiple axes, thereby adjusting the contact points and load distribution according to the specific pipe diameter and weight. This parameter adaptation enables the same device to safely handle pipes of varying sizes without causing indentation or damage.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple turning devices are kept for different pipe diameters, then each device can be optimized for a specific size, but the overall device complexity and material requirements increase

Engineering Contradiction:
Improvehandling different pipe diametersVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The turning device is designed as a universal multi-functional system where the rocker elements can pivot about multiple axes to accommodate pipes of different diameters. Instead of requiring separate devices for each pipe size, this single device can be adjusted through pivot movements to suit various pipe dimensions, thereby reducing the total number of components and simplifying the overall system.

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

Solution Approach 2:

The dynamic pivoting capability of the rocker elements about multiple axes enables the device to adapt its configuration for different pipe diameters. This dynamic adjustment mechanism replaces the need for multiple static devices, reducing complexity while maintaining versatility across different pipe sizes.

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple rollers are used to support large pipes, then the load distribution improves, but the dead weight of the turning device increases

Engineering Contradiction:
Improveeven weight distributionVSAvoiddead weight of turning device
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The rocker elements pivot about multiple axes to dynamically position the rollers for optimal weight distribution. This dynamic adjustment allows the device to achieve even load distribution with fewer rollers compared to static configurations, thereby reducing the dead weight of the turning device while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

AI summary

Provided is a turning device for turning pipes with a large diameter about their longitudinal axis. The turning device includes a base body and two supporting devices that are arranged on the base body. Each supporting device includes a pedestal and at least one rocker element that is pivotably mounted in a receptacle of the pedestal. The pedestal is connected to the base body. The rocker elements each include one or more rollers. The turning device adapts to different pipe diameters as a result of the rocker elements, so that no exchanging of the turning device is necessary and multiple turning devices do not need to be kept on hand for different pipe diameters.
