Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorized deployment systems for boat fenders are complex and expensive, posing risks of personal injury and damage to boats during docking, especially in adverse weather conditions, and lack efficient and reliable mechanisms for safe and convenient deployment and retrieval.
Innovation Solution
A reduced-complexity fender positioning system utilizing one or more motors connected to a line that raises or lowers boat fenders, with a controller and power source, including safety features like overcurrent detection and a safety release, and optionally using solar power and wireless communication for remote control via mobile devices, to facilitate safe and convenient deployment and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual deployment of fenders is used, then the system complexity is low, but the risk of personal injury and damage to boats increases
Solution Approach 1:
The patent replaces manual mechanical deployment with an automated motorized system. A motor unit is connected to a line that raises and lowers the fender, eliminating the need for manual handling. This substitution reduces system complexity while improving safety by removing operators from hazardous positions near the water edge during fender deployment and retrieval operations.
2Reliability
If current motorized deployment systems are used, then safety is improved, but device complexity and cost increase
Solution Approach 1:
The patent segments the fender deployment system into independent modular components: a motor unit, a line, a fender, and a control system. Each component can be independently selected, replaced, or maintained. This modular segmentation reduces overall system complexity while maintaining safety benefits, as opposed to integrated complex systems where components are interdependent and harder to manage.
Solution Approach 2:
The motorized system performs self-service by automatically raising and lowering the fender without requiring manual intervention. The system monitors and controls its own operation, reducing the need for complex manual control mechanisms and simplifying the overall system architecture while maintaining high safety standards.
3Reliability
If current motorized deployment systems are used, then safety is improved, but cost increases
Solution Approach 1:
The patent employs cost-effective components that can be easily manufactured and replaced if needed. The motor unit, line, and fender are selected as affordable, off-the-shelf components rather than custom-engineered parts. This approach maintains safety through reliable automated operation while significantly reducing manufacturing and acquisition costs compared to complex proprietary motorized systems.
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
The system enables safe, convenient, and cost-effective deployment and retrieval of boat fenders, reducing the risk of injury and damage, while improving reliability and usability, especially in challenging weather conditions.
Implementation Method 1
at least one motor capable of letting out or reeling in a line... the operation of the motor causes at least one end of the fender to be raised or lowered
Implementation Method 2
The motor may be powered by a solar panel or other power source
