Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater manipulators have limited mobility and are complex in structure and costly to manufacture, restricting their working range and functionality.
Innovation Solution
An underwater manipulator design featuring a mounting disc with a lifting and driving part for horizontal movement, mechanical claws controlled by a control part, and a semicircular or hemispherical manipulator main body with elastic limiting nets for grabbing and dragging operations, allowing for long-distance movement and versatile seabed work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the manipulator is attached to an underwater robot or water ship body for short-distance operation, then the manipulator can be controlled to move, but the working range is limited and long-distance movement is not possible
Solution Approach 1:
The manipulator system is divided into independent functional modules: mounting disc for positioning, manipulator main body for housing mechanisms, mechanical claws for manipulation, and control part for operation. This segmentation allows each component to be optimized independently while maintaining overall system simplicity for long-distance deployment
Solution Approach 2:
The mounting disc serves multiple functions: it provides the mounting surface for the manipulator main body, acts as a floating platform for extended working range, and includes limiting mooring rope connections for position control. This multi-functionality reduces the need for additional complex support structures
2Adaptability or versatility
If the manipulator is designed with complex function and structure, then the manipulation capability is enhanced, but the manufacturing cost becomes too high
Solution Approach 1:
The mechanical claws are designed to be self-contained units with integrated driving mechanisms within the manipulator main body. The control part directly actuates the claws through simple mechanical linkages, eliminating the need for complex external control systems and reducing manufacturing costs while maintaining manipulation versatility
Solution Approach 2:
The manipulator main body can accommodate different configurations of mechanical claws and driving mechanisms by changing internal arrangement parameters rather than redesigning the entire structure. This allows versatile manipulation capabilities through simple parameter adjustments, keeping manufacturing costs low
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the manipulator to move freely over a specific range, reduce dependency on a water ship body or underwater robot, and perform various underwater tasks efficiently with synchronized mechanical claws and elastic nets for object handling.
Implementation Method 1
The lifting part includes an expansion ball body fixedly connected with the mounting disc. The expansion ball body is communicated with a gas pipe
Implementation Method 2
The driving part includes a driving shaft and a propeller fixedly arranged on the driving shaft, the driving shaft penetrates through the rotating shaft and is parallel to the upper fixed disc, and the driving shaft is driven by a first motor

AI summary
An underwater manipulator that includes a mounting disc which is connected with a lifting part configured for controlling the mounting disc to ascend and descend; and a driving part configured for controlling the mounting disc to move horizontally; a manipulator main body fixedly arranged on one side of the mounting disc; and a plurality of mechanical claws slidably connected with an interior of the manipulator main body, where each mechanical claw is controlled by a control part to rotate. Lifting of the mounting disc is directly controlled through the lifting part, and the mounting disc is driven by the driving part to move in a certain plane in water, so that the manipulator can randomly move in a specific range and can move for a long distance, and the limitation of a water ship body or an underwater robot on the manipulator is reduced.
