METHOD FOR DESIGNING QUATERNION JOINT AND QUATERNION JOINT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18378194 titled 'METHOD FOR DESIGNING QUATERNION JOINT AND QUATERNION JOINT

Simplified Explanation

The patent application describes a method for designing a quaternion joint where a first member is rotatably coupled to a second member through links. The distances between the ends of the links, as well as the required distance to secure a degree of freedom of the end of the link, are set based on a constraint condition involving an ellipse.

• The method involves setting specific distances between the ends of the links and the required distance to secure a degree of freedom based on a constraint condition involving an ellipse.
• The constraint condition ensures that the distances between points on the ellipse corresponding to the start and end operating angles of the link are equal after shifting the center point of the ellipse by the required distance.

Potential Applications

The technology could be applied in robotics, mechanical engineering, and industrial automation for designing efficient quaternion joints.

Problems Solved

This technology solves the problem of accurately designing quaternion joints with the required degrees of freedom while maintaining structural integrity and stability.

Benefits

The benefits of this technology include improved performance, increased precision, and enhanced reliability in quaternion joint design.

Potential Commercial Applications

Possible Prior Art

One possible prior art could be traditional methods of designing quaternion joints without considering the constraint condition involving an ellipse.

Original Abstract Submitted

In a method for designing a quaternion joint where a first member rotatably coupled to a second member through links, a distance hbetween both ends of the link at an initial position of an operating angle of the link, a distance wbetween ends of the adjacent links, and a distance ho required to secure a degree of freedom of the end of the link are set based on a constraint condition in which a distance between a point on an ellipse corresponding to the start operating angle of the link and a point at which a center point of the ellipse is shifted by the distance ho and a distance between a point on the ellipse corresponding to an end operating angle of the link and a point at which the center point of the ellipse is shifted by the distance ho are made equal to each other.
