Solution Overview

Problem

Current ballast water treatment methods, particularly using electrolytic methods and chemical germicides like Sodium dichloroisocyanurate (NaDCC), face challenges in freshwater areas, are hazardous to handle, and require complex systems due to dust scattering and handling issues with granule types.

Innovation Solution

A ballast water treatment apparatus using granule type NaDCC with cartridges and a dissolution tank, featuring a transparent window for monitoring, manual and auto-valves, a cooling unit, and sensors for controlled dissolution and injection, allowing safe and efficient handling and treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If granule type NaDCC is used for ballast water treatment, then sterilizing power and cost-effectiveness are improved, but handling difficulty increases due to dust scattering

Engineering Contradiction:

Improvesterilizing powerVSAvoidhandling difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent divides the granule type NaDCC into contained units within a cartridge assembly. The cartridge separates the NaDCC granules from the external environment, preventing dust scattering while maintaining sterilizing effectiveness. This segmentation allows safe handling without requiring expert operators or extensive safety equipment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a cartridge as an intermediary container between the NaDCC granules and the ballast water treatment system. This intermediary structure prevents direct contact and dust scattering, enabling easier and safer handling while maintaining the sterilizing power of the NaDCC.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If aqueous solution type NaDCC is used, then ease of handling is improved, but storage and treatment capacity are reduced due to large volume and temperature degradation

Engineering Contradiction:

Improveease of handlingVSAvoidstorage capacity

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent changes the physical state parameter of NaDCC from aqueous solution to granule form. This parameter change reduces volume and eliminates temperature-related degradation, while the cartridge system maintains ease of handling through automated dissolution and injection mechanisms.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If electrolytic method is used for ballast water treatment, then treatment efficiency in seawater areas is improved, but applicability is reduced in freshwater areas

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidapplicability area

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent uses NaDCC as a universal germicide that functions effectively in both seawater and freshwater environments. Unlike electrolytic methods that require salt concentration, the chemical germicide NaDCC provides consistent treatment efficiency across different water types, enhancing system adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Object-affected harmful factors

If separate ventilator is added to prevent NaDCC dust scattering, then safety is improved, but system complexity and size increase

Engineering Contradiction:

ImprovesafetyVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments the NaDCC containment within a sealed cartridge structure, eliminating the need for additional ventilator systems. This segmentation approach maintains safety by preventing dust scattering while avoiding the complexity and size increase associated with adding separate ventilation equipment.

Inventive Principle:

Principle #1Segmentation
