Solution Overview

Problem

Existing air circulation systems in vessels occupy valuable space on decks, necessitating the use of dedicated acoustic insulation and compromising the availability of space for passenger comfort and recreational areas, as they require blowers and air ducts that take up space intended for other uses.

Innovation Solution

The air circulation system is reconfigured to house blowers on the lowermost deck near the vessel's flanks, with air ducts developing inside the hull between the blowers and air ports on the flanks, minimizing deck space usage and utilizing porthole frames for air ports to maintain a sleek appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If air circulation systems are installed with blowers and air ducts on decks, then ventilation and air conditioning functions are achieved, but valuable deck space is occupied and acoustic insulation requirements increase

Engineering Contradiction:
Improveventilation functionVSAvoiddeck space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The air circulation system transitions from a two-dimensional deck-mounted configuration to a three-dimensional arrangement utilizing the vertical space within the hull. Air ducts are routed through the hull's internal volume rather than occupying deck surface area, effectively moving the system into a different spatial dimension. This allows blowers to be positioned on the lowermost deck while air ducts develop inside the hull structure, freeing up valuable deck space for passenger use.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If traditional air circulation systems are installed, then air ventilation is provided, but dedicated acoustic insulation space is required

Engineering Contradiction:
Improveair circulationVSAvoidacoustic insulation requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The air circulation system merges the air duct routing with the hull's structural framework. Air ducts are integrated into the hull's internal architecture, developing inside the hull between blowers and air ports rather than requiring separate dedicated spaces for both air circulation and acoustic insulation. This consolidation eliminates the need for additional dedicated acoustic insulation spaces while maintaining effective air circulation.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If blowers are positioned on upper decks, then air distribution is simplified, but space intended for passenger comfort and recreation is compromised

Engineering Contradiction:
Improveair distributionVSAvoidpassenger space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The air circulation system is segmented into functionally independent components positioned at different vertical levels. Blowles are positioned on the lowermost deck where space is less critical, while air ports are distributed throughout the hull structure. Air ducts connect these segments through the hull's internal volume, allowing air distribution functionality to be maintained without concentrating all components in space-critical upper deck areas.

Inventive Principle:
Principle #1Segmentation

AI summary

A vessel having an air circulation system allowing better exploitation of the spaces inside the vessel is provided. The flanks of the hull of the vessel are used for accommodating at least part of the components of the air circulation system to free up useful space on decks, in order to use it for other purposes. Porthole frames are used for making air ports for the ventilation and air conditioning system to simplify the design of the system and not to deteriorate the outer appearance of the hull.
