Multi-Eversion Actuator Control With a Single Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems using multiple linear actuators are costly and complex due to the need for multiple motors, which increases size and expense.
Innovation Solution
A system and method to control multiple eversion-based actuators using a single motor or no motor, employing an activation mechanism with a rotating shaft, clutch, brake, and pressure sources to expand and retract the actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple linear actuators are used, then the required linear motion function is achieved, but the size and cost increase due to multiple motors
Solution Approach 1:
Multiple eversion-based actuators are merged into a single integrated system where a single motor drives multiple reels through a common shaft. The actuators share common components including the motor, shaft, clutch mechanism, brake, and pressure source, eliminating the need for multiple separate motors while maintaining independent control capability
Solution Approach 2:
The single motor system serves multiple functions by controlling different numbers and combinations of eversion-based actuators. The universal control mechanism can operate with any number of actuators from one to multiple, adapting to different application requirements without requiring additional motors
2Ease of operation
If multiple linear actuators are used, then the required linear motion function is achieved, but the cost increases due to multiple motors
Solution Approach 1:
The system merges multiple actuators into a single manufactured unit with shared components. By combining the motor, shaft, clutch, brake, and pressure source into one integrated assembly, the manufacturing cost is reduced compared to producing and assembling multiple separate actuator systems

AI summary
Disclosed here is a system and method to control multiple eversion-based actuators using a single motor, or no motor, thereby reducing the size and cost of the multiple eversion-based actuators. An activation mechanism can include a motor rotating in an expansion direction, rotating shaft, clutch, brake, pressure source under high pressure, and/or valve. The activation mechanism can cause the actuators including a wound reel of material to unwind and lengthen. A retraction mechanism can include a motor rotating in a contraction direction opposite the expansion direction, rotating shaft, clutch, pressure source having low pressure, valve associated with the pressure source, and/or the passive retraction system. The retraction mechanism can cause the actuators to rewind and shorten.
