Wellbore Connector With Rotating Lug for Force and Power Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellbore connectors are time-consuming to connect and disconnect, and they lack the ability to efficiently transfer significant mechanical forces and electric power/signal simultaneously.
Innovation Solution
A force-transferring wellbore connector with a box part and pin part design, featuring a lug that rotates to engage a locking shoulder for secure mechanical connection and an electric connection arrangement for power/signal transmission, allowing quick and secure attachment and detachment with the capability to handle forces over five metric tonnes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional wellbore connectors are used, then mechanical force transfer is achieved, but connection and disconnection time is excessive
Solution Approach 1:
The connector employs a dynamic latching mechanism where the lug rotates between engaged and disengaged states relative to the locking shoulder. This dynamic element allows rapid transition between connected and disconnected states, reducing operation time while maintaining secure mechanical force transfer capability when engaged.
Solution Approach 2:
The connector is divided into distinct functional components: a box part, a pin part with a rotatable lug, and a locking shoulder. This segmentation allows independent optimization of each component's function and enables the lug to rotate independently for quick engagement/disengagement without moving the entire connector assembly.
2Strength
If a secure mechanical connection is provided for high force transfer, then connection strength is improved, but the complexity of the connector increases
Solution Approach 1:
The rotating lug provides a dynamic locking mechanism that engages with the locking shoulder to create a secure mechanical connection capable of transferring high forces (more than five metric tonnes). The simplicity of the rotating engagement mechanism achieves high strength without requiring complex multi-component locking systems.
Solution Approach 2:
The connector merges mechanical force transfer and electrical connection functions into a single integrated assembly. The pin part and box part simultaneously provide both mechanical coupling through the lug-locking shoulder interface and electrical connection through the electric connection arrangement, reducing overall system complexity.
3Adaptability or versatility
If mechanical force transfer and electrical connection are combined, then functionality is improved, but device complexity increases
Solution Approach 1:
The connector integrates mechanical force transfer and electrical connection into a single unified device. The pin part and box part serve dual purposes: providing mechanical coupling through the lug-locking shoulder engagement while simultaneously establishing electrical contact through the electric connection arrangement, thereby achieving versatility without proportionally increasing complexity.
Solution Approach 2:
The connector is designed as a multi-functional device that can simultaneously transfer mechanical forces (more than five metric tonnes) and conduct electrical power and/or signals. This universal design allows a single connector assembly to replace what would traditionally require separate mechanical and electrical connections, improving adaptability while managing complexity.
