Motorized Winch Boat Fender Deployment System

Solution Overview

Problem

Boat operators face challenges in safely and conveniently deploying boat fenders, especially in stormy weather or large waves, as existing methods are tricky and dangerous, and there is a need for remote, motor-driven, and GPS-controlled deployment systems with mobile device control and automatic fender deployment based on location.

Innovation Solution

A system with stowage baskets for fenders that use a line to pull the fender into the basket, a motorized winch with wireless control, and a smartphone app for remote deployment and automatic deployment based on GPS, along with a camera for visual assistance and tangle detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual deployment methods are used, then the system is simple, but the ease of operation deteriorates and operator safety worsens in stormy weather

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical deployment with an automated motor-driven winch system controlled by a microcontroller. The winch mechanically reels in the fender line automatically, eliminating the need for operators to manually handle lines in dangerous conditions. The system uses electrical motors and electronic control circuits instead of pure mechanical manual operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service deployment through automated detection and control. The microcontroller automatically detects when the boat is approaching a dock using sensors and GPS, then autonomously controls the winch to deploy fenders without requiring operator intervention. The system serves itself by making decisions and executing actions based on environmental conditions.

Inventive Principle:
Principle #25Self-service

2Reliability

If remote motor-driven deployment is implemented, then operator safety improves, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical deployment with an automated motor-driven winch system controlled by a microcontroller. The winch mechanically reels in the fender line automatically, eliminating the need for operators to manually handle lines in dangerous conditions. The system uses electrical motors and electronic control circuits instead of pure mechanical manual operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a microcontroller as an intermediary between the sensors/GPS system and the motor-driven winch. This intermediary processes information from environmental sensors and GPS, makes decisions about when deployment is needed, and controls the motor execution. The intermediary layer manages the complexity by organizing control logic and coordinating between different system components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If automatic deployment based on GPS location is added, then ease of operation improves, but device complexity and energy consumption increase

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system uses periodic action by only activating the motor-driven deployment when specific conditions are met (GPS detection of dock proximity, sensor detection of docking need). The microcontroller monitors conditions continuously but only consumes significant energy when actual deployment action is required. This periodic activation rather than continuous operation reduces overall energy consumption while maintaining automated functionality.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system enables self-service deployment through automated detection and control. The microcontroller automatically detects when the boat is approaching a dock using sensors and GPS, then autonomously controls the winch to deploy fenders without requiring operator intervention. The system serves itself by making decisions and executing actions based on environmental conditions.

Inventive Principle:
Principle #25Self-service

4Reliability

If multiple sensors and cameras are integrated for tangle detection, then reliability improves, but device complexity and cost increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple sensing functions into an integrated system. The microcontroller consolidates inputs from various sensors (GPS, proximity sensors, line tension sensors) and a camera into a unified control architecture. By merging these functions under a single control unit, the system achieves reliable multi-functional monitoring while managing complexity through integrated rather than separate control circuits for each function.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An enhanced system and various methods for remotely deploying boat fenders from a safe and convenient location. The fenders, which are placed along the entire periphery of the boat, may be deployed and retracted with lines attached to winches and motors. A user interface application installed on a mobile device may be utilized to alert the need for deploying boat fenders upon entering known ports, and may also deploy the fenders automatically.
