Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical attachment system (clamps, cam fasteners, hydraulic jaws) is used for connection to an external network, then the connection strength and reliability are improved, but the device complexity and installation cost increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmechanical attachment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical attachment systems (clamps, cam fasteners, hydraulic jaws) with a simple magnetic attachment system. The magnetic connection device uses magnetic attraction forces to secure the flexible transfer pipe to the ship's hull, eliminating the need for complicated mechanical fastening mechanisms while maintaining reliable connection strength.

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

2Ease of manufacture

If ballast water is discharged directly into the sea through a simple orifice, then the installation cost and device complexity are reduced, but ecological harm increases due to discharge of invasive species and pathogens

Engineering Contradiction:
Improveinstallation simplicityVSAvoidecological harm from invasive species
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a flexible transfer pipe as an intermediary component between the ship's discharge orifice and the external network. This pipe can be connected to treatment facilities or other systems, enabling ballast water treatment while maintaining the simplicity of the original discharge system. The intermediary pipe allows integration of treatment capabilities without requiring modification of the ship's hull orifice.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If treatment systems are installed on older vessels with non-standardized orifices, then ballast water treatment capability is improved, but the installation cost and complexity increase significantly

Engineering Contradiction:
Improveballast water treatment capabilityVSAvoidinstallation complexity for older vessels
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal connection system using a flexible transfer pipe with magnetic attachment capabilities that can connect to various types of orifices regardless of their shape, size, or standardization. This universal interface allows treatment barges and other mobile treatment facilities to service older vessels with non-standardized orifices without requiring vessel-specific modifications, thereby reducing installation complexity while maintaining treatment capability.

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

4Ease of operation

If a standardized mechanical connection system is integrated into the ship's orifice, then connection reliability and ease of operation are improved, but the adaptability to different vessel types and the simplicity of the original system are reduced

Engineering Contradiction:
Improveconnection easeVSAvoidadaptability to different orifices
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

Instead of integrating connection systems into the ship's hull orifices, the patent inverts the approach by bringing the connection system to the flexible transfer pipe itself. The magnetic attachment device is mounted on the pipe, allowing it to adapt to various orifice configurations without modifying the ship. This inversion maintains the original simplicity of vessel orifices while providing ease of operation through the self-contained magnetic connection system.

Inventive Principle:
Principle #13The other way round (Inversion)
