WELLBORE TRACTOR WITH INVERTED TOROID - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240318517 titled 'WELLBORE TRACTOR WITH INVERTED TOROID
Simplified Explanation: The patent application describes a tractor assembly with a toroidal-shaped fluid-filled membrane that can be inverted using a helical flight drive system. The assembly includes telescoping sleeve-like portions that allow the body to shorten in length. When the membrane is inverted in a passage, frictional contact between the membrane and the inner surface of the passage creates a force that propels the tractor assembly through the passage.
- The tractor assembly includes a toroidal-shaped fluid-filled membrane mounted over a body.
- A drive system coupled with the membrane includes a helical flight that inverts the membrane when rotated against its inner surface.
- Telescoping sleeve-like portions on the body allow for shortening of the body length.
- Fluid in the membrane is forced from the mid-section, expanding a forward portion and creating frictional contact with the inner surface of the passage.
- The frictional contact generates a force that propels the tractor assembly through the passage.
Potential Applications: 1. Agricultural machinery for navigating tight spaces. 2. Industrial equipment for moving through narrow passages. 3. Robotic systems for exploration in confined environments.
Problems Solved: 1. Maneuvering through narrow passages. 2. Efficient propulsion in confined spaces. 3. Overcoming frictional resistance in tight environments.
Benefits: 1. Improved maneuverability in restricted areas. 2. Enhanced efficiency in navigating confined spaces. 3. Reduced energy consumption during propulsion.
Commercial Applications: The technology could be utilized in agricultural machinery, industrial equipment, and robotic systems for various commercial applications requiring navigation through narrow passages.
Questions about Tractor Assembly: 1. How does the helical flight drive system work to invert the membrane? 2. What are the potential advantages of using a toroidal-shaped fluid-filled membrane in this tractor assembly?

Original Abstract Submitted
a tractor assembly includes a toroidal shaped fluid filled membrane mounted over a body and a drive system coupled with the membrane. the drive system includes a helical flight that inverts the membrane when rotated against its inner surface. a mid-section of the body includes sleeve like portions that telescope with one another and shorten a length of the body. fluid in the membrane is forced from the mid-section and radially expands a forward portion and into contact with an inner surface of the passage, so that when the membrane is inverted while in a passage, frictional contact between the membrane and inner surface of the passage creates a force that urges the tractor assembly through a passage.
