Single Actuator Linear Rotating Device for Ceiling Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linearly moving and rotating devices for ceiling transport vehicles require two actuators, leading to increased size and weight, which is undesirable for supporting loads in ceiling transport vehicles.
Innovation Solution
A linearly moving and rotating device that uses a single actuator to move the article support portion along a straight direction and rotate it about a perpendicular axis, with an operating state switching mechanism to switch between linear movement and rotation, reducing the device's size and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two actuators are provided to enable both linear movement and rotation of the article support portion, then the device can achieve both movement functions, but the size and weight of the device increase
Solution Approach 1:
The single actuator is designed to perform multiple functions by switching between linear movement mode and rotation mode, replacing the need for two separate actuators. The actuator includes a drive shaft that can alternatively execute linear displacement or rotational motion based on the operational requirements, achieving multi-functionality with a single component.
Solution Approach 2:
The actuator is designed with dynamic switching capability between two operational states: linear movement state and rotation state. The drive shaft can alternatively function as a linear actuator or a rotational actuator through mechanical configuration changes, allowing the system to adapt its mode of operation based on whether linear positioning or rotational orientation is required.

Solution Approach 2:
The linear movement function and rotation function are merged into a single actuator system. The drive shaft and associated mechanical components are configured to alternatively produce linear motion or rotational motion, combining what would traditionally require two separate actuators into one integrated unit, thereby reducing the overall device size.

AI summary
The linearly moving and rotating device includes a support portion that supports an operated member integrally provided with the article support portion, for rotation about the movable axis and for movement along the first direction, and a linearly movable member which is moved along the first direction by the actuator. The operated member is connected to the linearly movable member in a portion spaced apart from the movable axis as seen along a direction along the movable axis. The linearly moving and rotating device includes an operating state switching portion which can be switched to a linearly moving state for restricting rotation of the operated member about the movable axis and for allowing movement of the operated member along the first direction, and to a rotating state for allowing rotation of the operated member about the movable axis and for restricting movement of the operated member along the first direction.
