Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional autonomous wellbore tools are used, then the tool can perform downhole operations autonomously, but the programming cannot be modified after deployment and no real-time communication is available

Engineering Contradiction:
Improveprogramming modifiabilityVSAvoidcommunication system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A communication device is introduced as an intermediary component between the autonomous wellbore tool and the surface system. This communication device enables wireless data transmission and programming updates without requiring complex redesign of the entire autonomous tool system, thus improving adaptability while managing complexity through modular addition.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The autonomous wellbore tool is enhanced with multi-functionality by integrating both autonomous operation capabilities and wireless communication capabilities into a single system. This allows the tool to not only perform downhole operations autonomously but also to receive programming updates and transmit data in real-time, thereby improving adaptability without requiring separate dedicated systems.

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

2Loss of information

If traditional autonomous wellbore tools are used, then the tool operates independently, but no real-time feedback or communication with surface operators is possible

Engineering Contradiction:
Improvedownhole operation feedbackVSAvoidenergy consumption for communication
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The communication system employs periodic transmission of data and feedback rather than continuous communication. The autonomous wellbore tool transmits operational status, sensor data, and receives programming updates at scheduled intervals or triggered by specific events, thereby providing real-time feedback information while minimizing continuous energy consumption for communication operations.

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If wireless communication capability is added to the wellbore tool, then real-time monitoring and remote programming become possible, but the device complexity increases

Engineering Contradiction:
Improveremote programming capabilityVSAvoidcommunication device integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wellbore tool system is segmented into distinct functional modules: the autonomous operation module and the communication device module. This segmentation allows the communication device to be added as a separate component, enabling remote programming and real-time monitoring capabilities while isolating the complexity of the communication system from the core autonomous operation system, thus managing overall device complexity more effectively.

Inventive Principle:
Principle #1Segmentation
