Solution Overview

Problem

Conventional ships are inefficient in maximizing cargo capacity due to the placement of accommodations and fuel tanks, which limits space utilization and increases vibration and noise, affecting navigation and comfort.

Innovation Solution

A cargo loading ship design that moves the deck house along the longitudinal direction of the hull, incorporating movable side walls and supporting units, allowing the deck house to be floated in emergency situations, and utilizing a hatch cover to open and close the cargo hold for efficient cargo loading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the deck house is fixed in position on the hull, then the structural stability is improved, but the cargo capacity is reduced due to space waste in the accommodation lower space

Engineering Contradiction:
Improvecargo capacityVSAvoidstructural complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the deck house movable along the longitudinal direction of the hull. The deck house can be positioned at different locations (first position near bow, second position near stern) to optimize cargo capacity. Movable side walls with supporting units enable the deck house to slide forward and backward, transforming the static structure into a dynamic one that adapts to different cargo loading requirements.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If the accommodation is located adjacent to the engine room, then the ship structure is simplified, but vibration and noise increase affecting navigation and comfort

Engineering Contradiction:
Improvevibration and noiseVSAvoidship structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies segmentation by separating the accommodation (deck house) from the engine room through strategic positioning. The movable deck house can be positioned away from the engine room location, creating spatial separation between the living quarters and the noisy engine compartment. This segmentation reduces vibration and noise transmission to the accommodation area while maintaining structural efficiency.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the lower side of the deck house is closed, then the structural integrity is improved, but the cargo loading efficiency is reduced

Engineering Contradiction:
Improvecargo loading efficiencyVSAvoidstructural integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent applies dynamics by making the lower side of the deck house openable and closable. The movable side walls can be opened to allow cargo loading from the sides, and closed when not in use to maintain structural integrity. This dynamic configuration enables efficient cargo operations while preserving the structural strength of the deck house.

Inventive Principle:
Principle #15Dynamics

4Volume of moving object

If the deck house is made movable to maximize cargo capacity, then the cargo capacity is improved, but the ease of operation deteriorates due to complex moving mechanisms

Engineering Contradiction:
Improvecargo capacityVSAvoidoperation simplicity
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies self-service through the automatic positioning capability of the deck house. The deck house can move to predetermined positions (first position for maximum cargo capacity, second position for other operational requirements) using its own driving mechanism. This self-service feature reduces the need for complex manual operation and external assistance, making the system easier to operate despite its mobility capabilities.

Inventive Principle:
Principle #25Self-service

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

This design maximizes cargo capacity by optimizing space utilization, reducing vibration and noise, and enhancing navigation and comfort by separating the accommodation from the engine room, thereby improving overall ship efficiency.

Implementation Method 1

The deck house may at least include a watertight bulkhead being formed under both sides thereof. The deck house may be separated from the plurality of side walls when a certain level of buoyancy is applied to the watertight bulkhead.

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)
