Solution Overview

Problem

Existing pipe machining apparatuses are large, heavy, difficult to assemble and position, and have limited coupling functionality, with roller bearings prone to premature wear due to improper lubrication.

Innovation Solution

A pipe machining apparatus with a split frame design featuring a hinge for relative movement of sections, adjustable coupling members for various pipe diameters, and a support system with a lifting mechanism, along with improved lubrication for roller bearings to enhance stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a split frame pipe machining apparatus is used to cut large diameter pipes, then the pipe can be machined, but the apparatus becomes large, heavy, and difficult to assemble and manipulate

Engineering Contradiction:
Improvecapability to machine large diameter pipesVSAvoiddifficulty to assemble and manipulate
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pipe machining apparatus is divided into two separate frame halves that can be assembled around the pipe. Each frame half includes corresponding tool carrier sections that can be independently handled and then coupled together, making the apparatus easier to transport and assemble while maintaining the capability to machine large diameter pipes

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If roller bearings are used between the tool carrier and frame, then movement is facilitated, but the bearings undergo significant stresses and wear prematurely due to improper lubrication

Engineering Contradiction:
Improvemovement of tool carrierVSAvoidpremature wear of bearings
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A lubrication system is introduced as an intermediary between the roller bearings and the contact surfaces. The system includes lubricant reservoirs and delivery mechanisms that ensure proper lubrication of the bearings during operation, reducing friction and preventing premature wear while maintaining smooth tool carrier movement

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If the pipe machining apparatus is designed with open ends for assembly, then it can be assembled around the pipe, but the tool carrier sections may slide off the frame sections

Engineering Contradiction:
Improveassembly of apparatusVSAvoidstability of tool carrier on frame
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

Retention features such as ledges, protrusions, or locking mechanisms are incorporated into the frame halves and tool carrier sections before assembly. These features prevent the tool carrier sections from sliding off the frame sections during the assembly process, ensuring stability while allowing the apparatus to be assembled around the pipe

Inventive Principle:
Principle #10Preliminary action
