Solution Overview

Problem

Earth drilling operations require multiple operators, leading to increased effort and costs, particularly due to the need for an additional operator to monitor the end of the drill pipe, which limits flexibility and efficiency.

Innovation Solution

A detection device is employed to detect the end of the drill string at the target pit, allowing the operator to relocate and enabling the control operator to take over monitoring responsibilities, thereby reducing the number of personnel required and allowing additional tasks to be assigned.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an additional operator is deployed to monitor the end of the drill string, then monitoring reliability is improved, but personnel costs and operational complexity increase

Engineering Contradiction:

Improvemonitoring reliabilityVSAvoidoperational complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/physical presence of a human operator at the drill string end with an automated detection device that uses sensors and signal processing to monitor drill string status, thereby eliminating the need for additional personnel while maintaining monitoring reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The detection device enables the system to self-monitor its own operational status by detecting the position and state of the drill string end, allowing the control operator to manage monitoring tasks remotely without requiring dedicated personnel at the drill string location

Inventive Principle:

Principle #25Self-service

2Reliability

If an additional operator is deployed to monitor the end of the drill string, then monitoring coverage is improved, but operational costs increase

Engineering Contradiction:

Improvemonitoring coverageVSAvoidpersonnel costs

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent substitutes human operators with an automated detection device that provides continuous monitoring of the drill string end, eliminating personnel costs while maintaining comprehensive monitoring coverage through sensor-based detection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The detection device performs multiple functions including position detection, status monitoring, and signal transmission, allowing a single automated system to replace multiple human operators and provide comprehensive monitoring coverage across different operational phases

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If operators are relocated and tasks are redistributed, then operational flexibility is improved, but control complexity increases

Engineering Contradiction:

Improveoperational flexibilityVSAvoidcontrol complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The detection device serves as an intermediary between the drill string end and the control operator, transmitting critical information automatically and enabling flexible task redistribution without requiring complex direct communication or coordination mechanisms between operators

Inventive Principle:

Principle #24Intermediary (Mediator)
