Solution Overview

Problem

Current portable threading machines are cumbersome, costly, and inefficient due to their large size, heavy weight, and the need for extensive setup and handling of cutting oil, which complicates transportation and storage.

Innovation Solution

A compact portable threading machine with a steel tubing frame, wheels, and an extendable handle, featuring a multi-compartment sump system that prevents oil spillage during transport and storage, and a design that reduces material costs by using lower-cost materials for non-structural components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a threading machine uses a large base housing to enclose all components and hold cutting oil, then structural support and component enclosure are improved, but weight and portability deteriorate

Engineering Contradiction:
Improvestructural supportVSAvoidmachine weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The base housing is divided into multiple sections: a main body housing for components and a separate sump for cutting oil. This segmentation allows the oil to be isolated in a dedicated compartment with spill prevention features, while the main housing provides structural support for mechanical components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sump is positioned at the bottom of the machine, utilizing vertical space rather than horizontal expansion. This dimensional approach allows oil containment without increasing the machine's footprint, and the spill prevention flange extends horizontally only when needed for sealing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If a threading machine includes a large reservoir of cutting oil, then lubrication and cooling are improved, but portability and risk of spillage during transport deteriorate

Engineering Contradiction:
Improvelubrication reliabilityVSAvoidmachine weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The cutting oil reservoir (sump) is segmented from the main machine body and equipped with a dedicated spill prevention flange. This allows the oil to be contained in a controlled compartment that can be sealed during transport, ensuring reliability of lubrication while minimizing spillage risk.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A spill prevention flange is pre-installed on the sump, positioned to contact the machine base and create a seal before transport begins. This preliminary protective measure prevents oil leakage during movement without requiring active intervention during transport.

Inventive Principle:
Principle #9Preliminary anti-action

3Stability of the object's composition

If a threading machine is designed for stationary use with all components enclosed in a base, then structural stability is improved, but ease of transport and setup deteriorate

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of transport
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The machine is segmented into a stable main body housing for operational use and a separate sump for oil containment. During transport, the sump can be positioned to engage with the base, providing stability during movement while maintaining structural integrity during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The machine design allows for dynamic configuration between operational and transport states. The sump can be positioned to provide stability during operation, then repositioned or secured for transport, enabling the machine to adapt its structural characteristics based on usage mode.

Inventive Principle:
Principle #15Dynamics

4Strength

If a threading machine uses cast aluminum or machined materials for the base, then structural support and cosmetic appearance are improved, but manufacturing cost deteriorates

Engineering Contradiction:
Improvestructural supportVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The base housing is segmented into functional areas: high-strength regions for structural support and load-bearing components, and lower-cost regions for non-critical enclosures. This allows selective use of expensive materials only where necessary, reducing overall manufacturing cost while maintaining required structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different material qualities are applied to different parts of the base housing. Critical structural areas use high-strength materials, while non-critical areas use lower-cost materials. The sump and its flange are designed with local quality considerations, using materials and manufacturing processes appropriate to their specific functional requirements.

Inventive Principle:
Principle #3Local quality
