Robot Swinging Mechanism With Circumferential Slot Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot designs with movable parts, such as tails and ears, require significant space and high costs due to the need for multiple actuators to achieve independent movement, which is not efficiently addressed by current technologies.
Innovation Solution
A driving mechanism comprising a driving member, a transmission member with a circumferential driving slot, and a swinging member that allows the movable part to move along the slot, enabling self-movement while occupying less space and reducing costs by simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actuators are used to achieve independent movement of movable parts, then the movement functionality is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple actuator functions into a single driving member that rotates to simultaneously control both the swinging motion and the raising/lowering motion of the movable part. The transmission member integrates multiple transmission functions (swinging transmission and position adjustment transmission) into one component, eliminating the need for separate actuators for each degree of freedom.
Solution Approach 2:
The driving member serves multiple functions: it generates swinging motion through the first transmission member and controls the raising and lowering positions through the second transmission member. This multi-functional design replaces what would traditionally require multiple specialized actuators, reducing overall system complexity while maintaining full movement capability.
2Adaptability or versatility
If multiple actuators are used to achieve independent movement of movable parts, then the movement functionality is improved, but the space requirement increases
Solution Approach 1:
By merging multiple actuator functions into a single rotating driving member and integrating multiple transmission functions into one transmission member, the patent significantly reduces the space required for actuator installation. The compact integrated structure allows the movable part to achieve independent multi-degree-of-freedom movement without occupying excessive robot body space.
3Adaptability or versatility
If multiple actuators are used to achieve independent movement of movable parts, then the movement functionality is improved, but the production cost increases
Solution Approach 1:
The patent merges multiple actuator requirements into a single driving member and combines multiple transmission functions into one transmission member with both a first transmission portion and a second transmission portion. This reduction in component count directly lowers production costs by reducing the number of actuators, transmission elements, and associated mounting structures needed, while still achieving independent multi-directional movement of the movable part.

AI summary
A driving mechanism includes a driving member, a transmission member, and a swinging member. The driving member has an output end. The transmission member is connected to the output end of the driving member. The transmission member has a driving slot, and the driving slot extends along a circumferential direction of the transmission member. The swinging member is configured to be movably connected to a body of a robot. A part of the swinging member is movably connected in the driving slot, and configured to move along the driving slot under drive of the transmission member to drive the swinging member to swing.
