Multi-Function Thruster for Underwater Robot Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater robots lack the flexibility and maneuverability to perform complex tasks in harsh underwater environments due to limited thruster configurations, which restrict their ability to provide thrust in multiple directions and adjust posture effectively.
Innovation Solution
A propulsion device with a bracket housing a first thruster and a second thruster, where either thruster can function as a horizontal, vertical, or vector thruster, allowing for flexible thrust direction and enhanced posture adjustment, integrated into an underwater robot with multiple vector thrusters for improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-direction thrusters are used, then the structure is simple, but the maneuverability and flexibility are limited
Solution Approach 1:
Each thruster is designed with a rotating joint that allows it to function in multiple roles: horizontal thruster, vertical thruster, or vector thruster. This multi-functionality enables a single thruster to replace what would traditionally require multiple fixed-direction thrusters, improving maneuverability while controlling system complexity
Solution Approach 2:
The thrusters are equipped with rotating joints that enable dynamic adjustment of thrust direction. The thrusters can rotate to change their orientation and function, transforming from static fixed-direction components to dynamic multi-directional propellers, thereby achieving superior maneuverability
2Adaptability or versatility
If multiple fixed-direction thrusters are added to improve maneuverability, then the thrust capability in multiple directions is enhanced, but the device complexity increases
Solution Approach 1:
Instead of adding multiple fixed-direction thrusters, the invention makes each thruster universal by enabling it to perform multiple functions through rotation. A single rotating thruster can provide horizontal thrust, vertical thrust, or angled vector thrust, replacing what would traditionally require three or more fixed thrusters
Solution Approach 2:
The invention merges the functions of multiple fixed-direction thrusters into a single rotating thruster. By combining horizontal, vertical, and vector thrust capabilities into one adjustable component, the system reduces the total number of thrusters while maintaining comprehensive thrust direction flexibility
3Ease of operation
If vector thrusters with rotating joints are used, then the posture adjustment capability is improved, but the device complexity increases
Solution Approach 1:
The thrusters incorporate rotating joints that enable dynamic posture adjustment. The rotating joint allows the thrust direction to be changed on-demand, providing real-time posture control capability that enhances ease of operation while maintaining a relatively simple mechanical structure

AI summary
Embodiments of the present disclosure relate to a propulsion device and an underwater robot. The propulsion device includes a bracket, a first thruster, and a second thruster. A first chamber and a second chamber are defined in the bracket, and the first thruster and the second thruster are respectively arranged in the first chamber and the second chamber. In a stationary state, in the case that the first thruster acts as a horizontal thruster or a vertical thruster, the second thruster functions as a vector thruster; or in the case that the second thruster acts as a horizontal thruster or a vertical thruster, the first thruster functions as a vector thruster.
