Modular Barrier Structure for Watercraft Using Pliable Sheet

Solution Overview

Problem

Conventional barrier structures for watercraft are expensive, complex to produce, and not easily adaptable to modular constructions, limiting their accessibility and versatility across different watercraft models.

Innovation Solution

A barrier structure comprising a frame with a pliable sheet wall connected to the frame, which is easily adjustable and cost-effective, allowing for modular construction to fit various watercraft lengths, featuring a rail for user grip and anchors for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If molded fiberglass sections are used for barrier structures, then aesthetic appearance is improved, but production cost and complexity increase significantly

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidproduction cost and complexity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The barrier structure is divided into modular sections that can be independently manufactured and assembled. Each module contains a frame with attached sheet material, allowing standardized production of identical units that can be configured in different lengths and arrangements to suit various watercraft models.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using rigid molded fiberglass sections, the invention employs thin sheet material (such as vinyl, fabric, or plastic) stretched over a frame structure. This approach achieves the desired aesthetic appearance while dramatically reducing manufacturing complexity and cost, as the sheets can be easily cut, shaped, and attached to standard frame modules.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If custom-sized fiberglass barrier structures are produced for each watercraft length, then fit and appearance are improved, but manufacturing complexity and inventory requirements increase

Engineering Contradiction:

Improveadaptability to different watercraft lengthsVSAvoidmanufacturing complexity and inventory requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The barrier structure is divided into modular sections that can be independently manufactured and assembled. Each module contains a frame with attached sheet material, allowing standardized production of identical units that can be configured in different lengths and arrangements to suit various watercraft models.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The standardized modules are designed to be universally applicable across different watercraft models and lengths. The same basic module can be used in various configurations (different numbers of modules, different arrangements) to accommodate multiple watercraft sizes, eliminating the need for custom-sized components for each model.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If tubular metal frames with sheet metal panels are used, then structural strength is improved, but production cost and installation complexity increase

Engineering Contradiction:

Improvestructural strengthVSAvoidproduction cost and installation complexity

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

Instead of using rigid molded fiberglass sections, the invention employs thin sheet material (such as vinyl, fabric, or plastic) stretched over a frame structure. This approach achieves the desired aesthetic appearance while dramatically reducing manufacturing complexity and cost, as the sheets can be easily cut, shaped, and attached to standard frame modules.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the material parameters from rigid sheet metal to more flexible, easier-to-install materials such as vinyl, fabric, or thin plastic sheets. These materials can be easily attached to the frame using staples, screws, or adhesive, significantly reducing installation complexity while maintaining adequate structural strength through the frame design.

AI summary

A watercraft includes a deck, a hull supporting the deck, and a barrier structure. The barrier structure includes: a frame connected to at least one of the deck and the hull and at least partially surrounding a portion of the deck; and a pliable sheet wall connected to the frame. The frame includes an upper portion including a rail for grabbing by a user's hand; and a lower portion connected to the at least one of the deck and the hull. The lower portion and the upper portion are connected to one another. The pliable sheet wall is stretched across at least a portion of the frame so as to extend between the upper and lower portions of the frame. A barrier structure is also contemplated.
