Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for laying cables in submarine stratum space, such as using drilling ships, are limited by their inability to move flexibly and cause significant disturbance, making them unsuitable for small-scale operations.
Innovation Solution
A submarine stratum space cable laying robot with a modular design and peristaltic motion mode, utilizing a telescopic electric linear actuator and supporting arm units for flexible forward motion and turning, reducing resistance through rotating mechanisms and adaptive baffle structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drilling ship is used for cable laying, then drilling depth and operation controllability are improved, but the ability to move flexibly deteriorates and the disturbance to the stratum increases
Solution Approach 1:
The drilling ship system is segmented into a main body and multiple detachable supporting arms. The supporting arms can be independently controlled to extend, retract, and position cables at different locations, enabling flexible movement while maintaining the stability of the main drilling platform.
Solution Approach 2:
The supporting arms are designed with dynamic adjustment capabilities, allowing them to extend and retract based on operational needs. This dynamic structure enables the system to adapt to different cable laying positions without moving the entire drilling ship, thereby improving flexibility while maintaining drilling reliability.
2Productivity
If a drilling ship operates continuously in situ, then large-scale exploitation operations are facilitated, but small-scale cable laying operations become less applicable
Solution Approach 1:
The system divides the cable laying function into the main drilling ship and detachable supporting arms. The supporting arms can be configured for different operation scales, allowing the same system to efficiently handle both large-scale exploitation operations and small-scale cable laying tasks by adjusting the deployment and configuration of the supporting arms.
3Ease of operation
If a traditional cable laying method is used, then cable installation is achieved, but the robot structure lacks modularity and flexibility
Solution Approach 1:
The robot is designed with modular components including a main body and multiple supporting arms that can be independently controlled. Each supporting arm is a separate module that can be adjusted, repositioned, and configured for different cable laying scenarios, enhancing both operational ease and structural flexibility.
Solution Approach 2:
The supporting arms incorporate dynamic adjustment mechanisms that allow real-time modification of their configuration and position. This dynamic modularity enables the robot to adapt to various cable laying requirements while maintaining a relatively simple base structure, balancing operational flexibility with structural complexity.

AI summary
A main body structure of a submarine stratum space cable laying robot includes one telescopic electric linear actuator unit including two dustproof sleeves with one sleeved on the other, and four single supporting arm units for forward motion and supporting. Two ends of each single supporting arm unit are sequentially provided with rotating supporting plates, reducers, motors and connecting flanges from inside to outside, and an outside of each single supporting arm unit is provided with a rotating plate structure. The single supporting arm units in each group are movably connected by the adjacent ends and movably connected to connectors of the telescopic electric linear actuator unit by respective outer ends thereof. The two groups of single supporting arm units connected in series are symmetrically arranged, such that a whole main body structure of the robot is diamond-shaped.
