Slim Universal Joint Structure for Independent X-Y Axis Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current universal joints cannot independently lock the X-Y rotating axes, restricting rotary motion and failing to transmit torque efficiently between differently aligned shafts, particularly in applications like unmanned air vehicles where free motion is essential during testing.
Innovation Solution
A slim type universal joint with a spherical inner part, central ring, and outer ring structure that allows independent locking of X-Y axes through strategically placed pin holes and cap pins, enabling rotation and locking of each axis separately by manipulating the positions of cap pins within specific holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a slim type universal joint structure is used to occupy less space, then the volume of the joint is reduced, but the ability to independently lock X-Y rotating axes is lost
Solution Approach 1:
The universal joint is divided into separate functional components: an inner part with spherical structure for X-axis rotation, and an outer part with slot for Y-axis rotation. Each part has its own locking mechanism (first locking pin for X-axis, second locking pin for Y-axis), allowing independent locking of each axis while maintaining a compact integrated design.
2Device complexity
If the universal joint structure is made simpler to reduce device complexity, then the number of parts is reduced, but the capability to transmit torque between differently aligned shafts is compromised
Solution Approach 1:
The patent combines multiple functions into a single integrated structure: the spherical inner part serves as both the X-axis rotation joint and the Y-axis rotation pivot, while the outer part's slot accommodates Y-axis rotation. The locking pins are integrated into this structure rather than being separate components, reducing overall complexity while maintaining torque transmission reliability between differently aligned shafts.
