Roller-Guided Mooring Line Structure for Storm Wave Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watercrafts experience damage during stormy weather due to the violent pitching motion caused by waves, which generates excessive tension in mooring lines, leading to the watercraft slamming into the mooring structure.
Innovation Solution
A mooring apparatus with a frame, rollers, and a tension bar that allows the mooring line to glide with the wave motion, reducing the kinetic energy transfer to the watercraft by enabling the line to move along a mooring structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mooring line is affixed to a stationary structure during stormy weather, then the watercraft is secured to the structure, but the kinetic energy from wave motion causes the watercraft to slam into the structure causing damage
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed stationary structure with a mobile platform that can move with the waves. The mobile platform is equipped with rollers that allow it to roll along the water surface, dynamically adapting to wave motion. This enables the mooring system to transition from a static configuration that causes impact damage to a dynamic configuration that absorbs wave energy through controlled movement, thereby maintaining mooring security while eliminating harmful impacts.
2Stability of the object's composition
If the mooring line is kept taut to secure the watercraft, then the watercraft remains stable, but the tension in the line increases during wave motion leading to line failure or structure damage
Solution Approach 1:
The patent applies the intermediary principle by introducing a mobile platform with rollers as a mediator between the watercraft and the mooring line. This intermediary device absorbs and dissipates the forces generated by wave motion through rolling movement, preventing these forces from being transmitted directly to the mooring line. The rollers act as a force-dissipating mechanism that maintains watercraft stability while reducing tension forces on the line to prevent failure.
3Ease of manufacture
If a traditional fixed mooring structure is used, then the installation is simple, but the structure cannot accommodate wave-induced motion leading to excessive kinetic energy transfer
Solution Approach 1:
The patent transforms the static mooring structure into a dynamic system by introducing a mobile platform that can move with the waves. This dynamic approach allows the system to accommodate wave-induced motion naturally, converting harmful kinetic energy transfer into controlled rolling motion. The mobile platform with rollers provides a simple yet effective mechanism that maintains ease of installation while fundamentally changing the energy interaction from harmful impact to beneficial motion absorption.
