Convertible Wiping Device for Downhole Tubular Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wiping devices in the downhole drilling and completion industry are limited in their ability to effectively engage and wipe tubular sections of varying dimensions, often requiring separate devices for different sizes, which increases complexity and costs.
Innovation Solution
A wiping device with a resilient body and a support member that can convert between two shapes, allowing it to adapt to different tubular dimensions by changing its center line configuration, enabling it to engage with tubular sections of varying sizes without the need for multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wiping device is designed to handle multiple tubular dimensions, then device versatility is improved, but device complexity increases
Solution Approach 1:
The support member is designed to dynamically change its shape between a first configuration (for smaller tubular sections) and a second configuration (for larger tubular sections). This dynamic transformation allows the wiping device to adapt to different tubular dimensions without requiring multiple separate devices, thereby improving versatility while managing complexity through a single transformable component rather than multiple fixed devices
Solution Approach 2:
The invention changes the geometric parameters of the support member by transforming its shape between two distinct configurations. This parameter change enables the wiping device to accommodate different tubular inner diameters, allowing a single device to perform multiple functions across varying dimensions without increasing overall system complexity
2Manufacturing precision
If multiple wiping devices are used for different tubular sizes, then wiping precision is improved, but device quantity and operational complexity increase
Solution Approach 1:
The wiping device is designed with universal applicability through the transformable support member that can configure itself for different tubular dimensions. This multi-functionality allows a single device to replace multiple specialized devices, maintaining wiping precision across various sizes while reducing the total number of devices needed and simplifying operational procedures
3Adaptability or versatility
If the support member transforms between shapes, then device adaptability is improved, but structural stability during transformation may worsen
Solution Approach 1:
The support member employs dynamic shape transformation between defined configurations while maintaining structural integrity during the transition. The design ensures that the member remains stable in each configuration state (first shape for smaller tubulars, second shape for larger tubulars) while enabling controlled transformation between states, thus balancing adaptability with structural stability

AI summary
A wiping device including a resilient body having a wiping surface. A support member is convertible between a first shape defined by a first center line of the support member and a second shape defined by a second center line of the support member. The support member is disposed relative to the resilient body to enable the resilient body to take a first set of dimensions when the support member is in the first shape and a second set of dimensions when the support member is in the second shape. A method of using a wiping device is also included.
