Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional threading techniques are used, then threads can be cut into pipes, but significant physical exertion is required and surrounding structures must be removed for access

Engineering Contradiction:

Improvephysical exertion requiredVSAvoidpreparatory work complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical threading operations with a power-driven die attachment that can be operated with minimal physical effort. The die is mounted on a power tool (drill, impact driver, or impact wrench) which provides the rotational force needed to cut threads, eliminating the need for manual cranking of traditional threaders.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The threading device is divided into separate modular components: a mounting adapter that attaches to the power tool, and a die that can be independently attached to the adapter. This segmentation allows for easy assembly and disassembly, and enables the use of different dies for various pipe sizes and thread types without replacing the entire tool.

Inventive Principle:

Principle #1Segmentation

2Productivity

If manual threading devices are used, then threading can be performed, but the process is inefficient and time-consuming

Engineering Contradiction:

Improvethreading efficiencyVSAvoidthreading time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mounting adapter is designed with pre-configured mounting holes and attachment mechanisms that allow for rapid installation of the die. The adapter itself can be pre-attached to the power tool, so that when threading is needed, the die can be quickly mounted without complex setup procedures.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If traditional threading devices are used in tight spaces, then threading can be accomplished, but the device requires significant space for operation

Engineering Contradiction:

Improveability to work in tight spacesVSAvoiddevice operating space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes the rotational dimension provided by the power tool to perform threading operations. Instead of requiring linear movement or manual manipulation in limited space, the powered rotation allows the compact die to cut threads effectively in confined areas where traditional manual threaders cannot reach or maneuver.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If specialized threading devices are used, then pipes can be threaded effectively, but multiple specialized devices are required for different pipe types and sizes

Engineering Contradiction:

Improvecompatibility with different pipe typesVSAvoidnumber of specialized devices

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting adapter is designed with universal compatibility features, including multiple opening configurations that can accommodate different die sizes and types. The adapter interface is standardized to work with common power tools (drills, impact drivers, impact wrenches), creating a single platform that can perform multiple threading operations across different pipe sizes and thread types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Inventive Principle:

Principle #1Segmentation

AI summary

A pipe threading device is provided. The device is comprised of an adapter that can be used to attach a die thread to an impact tool or similar tool. In another embodiment, the device is also comprised of a die thread. The adapter is comprised of a bottom member with multiple openings to accommodate different types and sizes of die threads, and at least one socket for attachment to a tool. The die thread, equipped with a thread-cutting member, is designed to cut threads into a pipe when rotated by the tool. This setup allows for the easy attachment of die threads to tools and facilitates the threading of pipes without manual operation.
