Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned ships face challenges with inaccurate berthing, damage from rain and malicious tampering, and reduced service life due to collisions with the shore during berthing, as they lack precise positioning and protection mechanisms.
Innovation Solution
An automatic berthing system with a position adjusting mechanism, including X-direction, Y-direction, and Z-direction adjusting assemblies, and a clamping claw mechanism with flexible damping connections, which allows for precise alignment and secure attachment to the shore, reducing wave impact and protecting the ship from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the unmanned ship directly stops at the shore without protection structure, then the berthing process is simple, but the high-end sophisticated electronics are exposed to rain and malicious damage
Solution Approach 1:
The protection structure is divided into multiple roof plates arranged at different positions along the shore, each providing localized protection. This segmentation allows the system to protect multiple berthing positions independently while maintaining a relatively simple overall structure.
Solution Approach 2:
The roof plates serve as intermediary structures between the shore and the unmanned ships, providing physical protection against rain and malicious damage while allowing the berthing process to remain relatively simple. The position adjusting mechanisms act as intermediaries to precisely position the clamping claws for secure attachment.
2Extent of automation
If the unmanned ship moves to the shore on its own without precise positioning, then the berthing operation is autonomous, but the ship collides with the shore resulting in poor berthing effect
Solution Approach 1:
The position adjusting mechanisms incorporate adjustable components that can dynamically adapt to different berthing positions and conditions. The clamping claws can be positioned and adjusted to accommodate variations in ship arrival positions, maintaining both automation and precision.
Solution Approach 2:
The system employs positioning mechanisms that can detect and adjust the position of the clamping claws based on the arrival position of the unmanned ship. This feedback mechanism ensures precise berthing while maintaining autonomous operation.
3Device complexity
If the unmanned ship is fixedly connected to the shore by rope after berthing, then the connection method is simple, but the ship moves back and forth under wave impact causing further damage
Solution Approach 1:
The flexible connection mechanisms incorporate damping elements that can absorb and dissipate wave energy, reducing the back-and-forth movement. The clamping claw mechanism provides a more stable connection compared to simple rope fixation.
Solution Approach 2:
The position adjusting mechanisms can adapt the connection parameters (position, angle, force) based on wave conditions and ship characteristics, providing optimized stability while maintaining reasonable structural complexity.
4Productivity
If multiple unmanned ships berth together, then the berthing efficiency increases, but the wave impact and collision risk increase
Solution Approach 1:
Multiple roof plates are arranged at different positions along the shore, allowing multiple unmanned ships to berth simultaneously at separate locations. This segmentation reduces the wave impact and collision risk between ships while maintaining high berthing efficiency.
