Solution Overview

Problem

Existing earth drilling devices have complex structures for their rod magazines and transfer devices, which complicate the simple transfer of rod sections and require unnecessary material and stabilization.

Innovation Solution

A guide for the transfer device is integrated onto the rod magazine, allowing the transfer device to move directly on it, eliminating the need for a separate support structure and simplifying the design and material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate support structure is provided for the transfer device, then the transfer device can be stabilized, but the structural complexity and material requirements increase

Engineering Contradiction:

Improvestability of transfer deviceVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support function into the rod magazine itself by providing guides on its head pieces, merging the storage structure and support function into a single integrated component, thereby reducing overall structural complexity while maintaining stability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rod magazine is given multiple functions: it serves both as the storage structure for rod sections and as the support structure for the transfer device through its integrated guides, eliminating the need for a separate dedicated support structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a separate support structure is provided for the transfer device, then the transfer device can be stabilized, but the material requirements increase

Engineering Contradiction:

Improvestability of transfer deviceVSAvoidmaterial requirements

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

By merging the support function into the existing rod magazine structure through integrated guides, the patent eliminates the need for additional separate support components, thereby reducing total material requirements while maintaining transfer device stability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rod magazine serves dual purposes as both storage and support structure, maximizing the utilization of existing materials and eliminating redundant material consumption that would occur with a separate support structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If the guide is integrated on the rod magazine, then the structural complexity is reduced, but the stability might be compromised

Engineering Contradiction:

Improvestructural complexityVSAvoidstability of transfer device

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The integration of guides directly onto the rod magazine's head pieces creates a rigid, fixed connection that provides stable support for the transfer device while maintaining simple overall structure, as the rod magazine itself serves as the stable base

Inventive Principle:

Principle #5Merging (Combining)
