Innovation Solution

Incorporating a Bluetooth device within the downhole probe assembly to enable wireless transmission of electrical information between the probe and a surface electronic interface, eliminating the need for manual disassembly and reassembly, and allowing for secure, efficient data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual manipulation of MWD tools is used for transferring instruction commands and configuration files, then data transfer can be accomplished, but human error increases and safety concerns arise due to improper handling and sealing

Engineering Contradiction:
Improvedata transfer reliabilityVSAvoidmanual handling difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical connection and disconnection process with a wireless communication system. The Bluetooth device enables data transfer without physical contact, eliminating the need for manual manipulation of the tool assembly. This substitution of mechanical operations with wireless electronic communication resolves the contradiction by maintaining data transfer capability while removing the safety and reliability issues associated with manual handling.

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

Solution Approach 2:

The Bluetooth device acts as an intermediary between the surface equipment and the downhole MWD tool. Instead of directly connecting surface equipment to the tool (which requires manual manipulation), the Bluetooth device mediates the data transfer process wirelessly. This intermediary approach allows reliable data transfer while avoiding the harmful effects of manual handling and improper sealing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the probe housing is opened for data transfer, then instruction commands can be downloaded, but the tool is exposed to harsh drilling conditions and potential failure

Engineering Contradiction:
Improvedata transfer capabilityVSAvoidexposure to harsh drilling conditions
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical opening and closing of the probe housing with a wireless communication system. The Bluetooth device remains sealed within the housing while enabling data transfer through wireless signals that penetrate the housing material. This eliminates the need to open the housing, thereby protecting the internal components from harsh drilling conditions while maintaining full data transfer capability.

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

Solution Approach 2:

The probe housing material is selected to be transparent or permeable to Bluetooth radio waves while maintaining its protective function. This allows the housing to act as both a protective barrier against harsh drilling conditions and a transmission medium for wireless signals, resolving the contradiction between protection and data transfer capability.

Inventive Principle:
Principle #30Flexible shells and thin films

3Loss of information

If conventional telemetry methods are used, then data can be transmitted to surface, but the system complexity increases and requires additional equipment

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidtelemetry system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The Bluetooth device performs multiple functions: it serves as both a data transfer interface and a configuration interface for the MWD tool. By integrating these functions into a single device, the system avoids the complexity of separate telemetry equipment while maintaining full data transmission capability. The Bluetooth device can communicate with both surface equipment and the tool's control system, providing universal functionality.

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

Solution Approach 2:

The patent extracts the data transfer function from the complex conventional telemetry system and implements it through a standalone Bluetooth device. This extracted approach simplifies the overall system by removing the need for complex telemetry hardware while maintaining the essential data transmission capability. The Bluetooth device handles all communication needs independently.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The embodiments described herein generally relate a downhole probe assembly incorporating a Bluetooth device for wirelessly transmitting electrical information between the downhole probe assembly and a surface electronic interface such as a computer when the probe assembly is above ground. The downhole probe assembly includes sensors for sensing downhole conditions; a controller in electrical communication with the sensors and configured to receive and process information from the sensors; a housing enclosing the one or more than one sensor and the controller; the Bluetooth device in electrical communication with the controller; and an end cap assembly fitted at one end of the housing. The end cap assembly partially surrounds the Bluetooth device and is configured for transmission of the electrical information therethrough. Also described is an end cap assembly for fitting to one end of a downhole probe assembly including a transmission module mated with and electrically connected to the Bluetooth device. The end cap assembly includes an end cap having an end cap mating section configured to mate with a mating section of the transmission module to form a chamber enclosing the Bluetooth device between the transmission module and the end cap. A known downhole probe assembly can be retrofitted with the Bluetooth device and end cap subassembly. The end cap subassembly is configured and adapted to promote signal transmission between the Bluetooth device and a surface computer or other electronic interface.
