Solution Overview

Problem

Current systems for storing and transporting live seafood face challenges such as increased operational tasks, limited storage capacity, and degradation of products due to stagnant water and restricted water flow, leading to compromised quality and taste.

Innovation Solution

A modular system with open-ended tubular housings made of lightweight materials, allowing direct placement of seafood and improved water circulation, reducing stagnation and increasing storage capacity, while maintaining optimal handling and transportability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If seafood products are frozen during transport, then they can be stored and transported easily, but they are no longer alive at destination and quality and taste deteriorate

Engineering Contradiction:
Improveease of transportVSAvoidproduct quality
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system changes the physical state parameter of the seafood from frozen to living by maintaining appropriate water temperature and circulation conditions, thereby preserving product quality while enabling transport

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses a hydraulic circuit to generate water circulation that keeps seafood alive during transport, replacing the frozen state with a controlled aquatic environment that maintains product vitality and quality

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Loss of energy

If seafood is stored in integral housings with hydraulic circuits, then water weight is reduced and transport costs decrease, but the number of operational tasks increases and storage capacity is limited

Engineering Contradiction:
Improvetransport costVSAvoidstorage capacity
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The system divides the storage into multiple separate tubular housings that can be arranged in arrays, increasing storage capacity while maintaining the hydraulic circulation benefits of the integral design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from single housings to multi-level stacked arrangements, utilizing vertical space to dramatically increase storage capacity without proportionally increasing water volume or transport cost

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

3Ease of operation

If complex hydraulic circuits with supply and overflow pipes are used, then water circulation is achieved, but water stagnation occurs in lower parts and flow rate is limited

Engineering Contradiction:
Improvewater circulationVSAvoidpreservation quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Instead of using complex supply and overflow pipe systems that create stagnation zones, the patent inverts the approach by using a bottom-up circulation system where water enters at the lowest point and flows upward through all housings, eliminating stagnation and maximizing flow rate

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

4Reliability

If seals are used to close housings, then water containment is achieved, but seal life is limited due to corrosive effect of salt water

Engineering Contradiction:
Improvewater containmentVSAvoidseal lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent accepts that seals will degrade due to salt water corrosion and designs the system to accommodate periodic maintenance and replacement of these consumable components, focusing on making the replacement process simple and the seals themselves inexpensive

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The system uses flexible sealing elements that can accommodate thermal expansion and contraction, as well as minor misalignments, thereby extending seal life in the corrosive salt water environment

Inventive Principle:
Principle #30Flexible shells and thin films
