Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The attachment of accessories to marine vessels can alter the maneuvering feeling and navigation performance, which may cause discomfort to the operator.

Innovation Solution

A marine vessel equipped with a controller that judges the attachment's presence and notifies the operator, and adjusts navigation settings accordingly to mitigate these changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If attachments are attached to the marine vessel, then the functionality and utility of the vessel are improved, but the maneuvering performance and navigation stability deteriorate

Engineering Contradiction:

Improvefunctionality with attachmentsVSAvoidmaneuvering performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The notification device provides feedback to the operator about the attachment state, enabling the operator to adjust maneuvering operations accordingly. This feedback loop allows the system to maintain reliability by informing the operator of conditions that may affect maneuvering performance.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If attachments are attached to the marine vessel, then the utility and functionality are enhanced, but the operator's awareness of the attachment state is reduced

Engineering Contradiction:

Improveutility with attachmentsVSAvoidoperator awareness

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The notification device establishes a feedback mechanism that continuously informs the operator about the attachment state. This eliminates information loss by providing real-time status updates, ensuring the operator is always aware of attached components regardless of their complexity or number.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the marine vessel navigates with attachments, then the versatility is improved, but the navigation performance changes adversely

Engineering Contradiction:

Improvenavigation versatilityVSAvoidnavigation performance

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

By notifying the operator of the attachment state, the system enables informed navigation decisions. The operator can adjust speed and routing based on the attached equipment, optimizing navigation performance while maintaining the versatility benefits of the attachments.

Inventive Principle:

Principle #23Feedback

AI summary

A marine vessel that is able to inform a vessel operator that an attachment is attached includes a hull and a controller configured or programmed to function as a judging unit to judge whether or not an attachment that is attachable and detachable to and from the hull is attached to the hull, and to function as a notifying unit to, in a case of being judged by the judging unit that the attachment is attached, execute a notification process to notify the vessel operator that the attachment is attached to the hull.
