Solution Overview

Problem

Existing boat trailers require multiple operators to load and unload boats, necessitating time-consuming alignment and manual handling, which is inefficient and labor-intensive.

Innovation Solution

An enclosed boat trailer with a roller system and winch mechanism that allows a single operator to load and unload a boat directly from the water without assistance, utilizing a roller system with adjustable components to accommodate various boat sizes and configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional boat trailers are used, then multiple operators are required to load and unload boats, but this increases labor requirements and time consumption

Engineering Contradiction:
ImproveEase of boat loading and unloadingVSAvoidOperational complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service operation where the boat operator independently loads and unloads the boat using the roller system and winch mechanism, eliminating the need for multiple operators to manually handle and align the boat with the trailer

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with an automated winch mechanism that uses a cable to pull the boat onto the trailer, substituting human physical effort with a mechanical assistance system

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

2Productivity

If manual alignment and handling are used, then loading and unloading processes are time-consuming, but this increases productivity requirements

Engineering Contradiction:
ImproveBoat loading and unloading efficiencyVSAvoidTime for alignment and manual handling
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The roller system is pre-positioned on the trailer floor to create a guided path that automatically directs the boat into the correct position during loading, eliminating the need for time-consuming manual alignment operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The winch mechanism automatically performs the time-consuming task of pulling the boat onto the trailer, replacing manual hauling operations and significantly reducing the time required for loading and unloading

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

3Adaptability or versatility

If fixed roller systems are used, then accommodation of various boat sizes is limited, but this reduces adaptability

Engineering Contradiction:
ImproveAccommodation of various boat sizes and configurationsVSAvoidRoller system configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The roller system incorporates adjustable and movable components that can be reconfigured to accommodate different boat sizes and types, transforming a static system into a dynamic one that adapts to various loading requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The roller system is designed with universal components that can serve multiple functions and accommodate various boat configurations, allowing a single system to handle different boat sizes and types without requiring specialized equipment for each case

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An illustrative embodiment of an enclosed boat trailer may be configured to allow loading of a boat in the water for the purpose of removing the boat from the water using the enclosed boat trailer to engage the boat for storage and/or transportation. An illustrative embodiment of an enclosed boat trailer may be comprised of a roller system positioned on the floor and a right and left rear arm adjacent a rear opening in the enclosed boat trailer. In an illustrative method of use, a boat operator may load and/or unload the boat into the water from the enclosed boat trailer without leaving the boat and without additional personnel.
