Innovation Solution

A modular top drive system equipped with active and passive identification devices, including RFID tags and barcode labels, that connect to a central control unit for automatic tool recognition and management, enabling automated tool exchange by reading identification information from tools and storing operational parameters and history.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual tool identification is used during tool exchange, then personnel can identify tools, but the process becomes time-consuming and hazardous due to working at heights

Engineering Contradiction:
Improvetool identification accuracyVSAvoidtool exchange time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual visual identification and mechanical tool handling with an automated identification system using RFID tags and readers. The system automatically detects tool identities through electromagnetic fields without requiring personnel to physically inspect tools or work at heights, thereby reducing both time and safety risks.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces RFID tags as intermediary elements attached to tools and RFID readers mounted on the top drive. These intermediaries enable automatic communication of tool identity information between the tool and control system, eliminating the need for manual identification while ensuring accurate tool recognition during exchange operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual tool identification is used, then personnel can verify tool correctness, but safety risks increase due to working at heights

Engineering Contradiction:
Improvetool verification accuracyVSAvoidpersonnel safety risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual verification processes with an automated RFID identification system. The reader automatically reads tool identifiers and the control system verifies correctness without requiring personnel to physically handle or visually inspect tools while positioned at heights, thereby eliminating safety risks associated with manual verification.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-verification where the RFID reader automatically reads and verifies tool identity information without human intervention. The control system compares the read identifier against the required tool type, providing automatic verification that ensures correctness while keeping personnel safely away from hazardous areas.

Inventive Principle:
Principle #25Self-service

3Productivity

If automated tool exchange is implemented, then efficiency improves, but system complexity increases due to identification devices and control systems

Engineering Contradiction:
Improvetool exchange efficiencyVSAvoididentification system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs universal RFID tags that can be attached to various tool types (drilling tools, casing tools, cementing tools) and a multi-functional top drive system with integrated RFID readers. This universal approach allows a single identification system architecture to handle diverse tool types, improving efficiency while managing complexity through standardization rather than requiring separate systems for each tool type.

Inventive Principle:
Principle #6Universality (Multi-functionality)
