Multi-Axis Lever Arm Linkage for Two-Dimensional Circular Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional levers are limited to linear movement and lack the capability to rotate simultaneously about two separate axes, restricting their ability to produce circular motion, and they do not have adjustable components.
Innovation Solution
An apparatus comprising a first frame, a second frame, a heim joint, and a lever with a fulcrum, allowing rotation about multiple axes, including a first, second, and third axis of rotation with a single point of intersection, and optionally a fourth, fifth, and sixth axis for three-dimensional movement, with adjustable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lever is used, then the structure is simple, but the movement is limited to linear direction only
Solution Approach 1:
The lever system is divided into multiple segments: a first lever arm rotatable about a first axis, and a second lever arm rotatable about a second axis. Each segment handles a specific rotational dimension, allowing the system to achieve complex two-dimensional circular motion while maintaining relatively simple individual components.
Solution Approach 2:
The invention transitions from one-dimensional linear motion to two-dimensional circular motion by introducing a second axis of rotation perpendicular to the first. The first lever arm provides rotation about the first axis, while the second lever arm provides rotation about the second axis, enabling the load to move in circular paths in multiple directions simultaneously.
2Adaptability or versatility
If a lever rotates about one axis, then the rotation is simple, but it cannot produce circular motion in two dimensions
Solution Approach 1:
The rotational capability is segmented into two independent axes: the first lever arm handles rotation about the first axis, and the second lever arm handles rotation about the second axis. This segmentation allows each component to be optimized for single-axis rotation while the combination achieves two-dimensional rotational capability.
Solution Approach 2:
The system adds another dimension of rotation by introducing a second axis perpendicular to the first axis. The first lever arm rotates about the first axis to provide motion in one plane, while the second lever arm rotates about the second axis to provide motion in a perpendicular plane, together producing two-dimensional circular motion.
3Adaptability or versatility
If a lever has fixed components, then the manufacturing is simple, but the application flexibility is limited
Solution Approach 1:
The invention incorporates adjustable elements that allow the lever arms and their connection points to be repositioned along the axes. This dynamic adjustability enables the same lever system to be configured for different circular motion radii, different axis orientations, and different load positions, providing application flexibility without requiring completely different fixed structures.
