Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mussel cultivation methods, such as using buoys and main carrier ropes, are prone to mussel loss due to vertical and horizontal forces from wind, waves, and tides, leading to oscillation, friction, and kinking issues.

Innovation Solution

A double pipe cultivation system that distributes loads across multiple points, using HDPE double pipe floaters with polystyrene foam filling, oscillation-absorbing guy ropes, and flexible connections to minimize movement and tension, preventing sinking and tangling, and allowing for efficient load distribution and absorption of wave and wind forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional buoy and main carrier rope systems are used for mussel cultivation, then the system structure is simple, but the mussels fall due to oscillation from wind, wave and tides causing significant loss

Engineering Contradiction:

Improvemussel retentionVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the single main carrier rope into multiple peripheral ropes suspended from a double pipe floater structure. This segmentation distributes the mussels across multiple support lines, reducing the oscillation amplitude on each individual rope and preventing mussels from falling off, thereby improving reliability without excessive complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-point suspension system to a distributed multi-point suspension system using a double pipe floater structure. By adding the horizontal dimension with multiple peripheral ropes extending from the pipe, the system stabilizes mussel retention across a broader spatial distribution, reducing the impact of vertical oscillations

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Strength

If single pipe floaters are used, then the device complexity is low, but the floaters sink under the weight of mussels and equipment

Engineering Contradiction:

Improvefloating capacityVSAvoidfloater structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The system merges two separate pipe structures to form a double pipe floater configuration. By combining the buoyancy of two pipes, the system achieves sufficient floating capacity to support the weight of mussels and equipment without sinking, while maintaining a relatively simple structural design that builds upon conventional single pipe systems

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The floaters utilize composite construction with HDPE (high-density polyethylene) pipes filled with polystyrene foam. This composite material approach provides both the necessary buoyancy strength and structural durability to support heavy loads while resisting degradation from marine environmental factors

Inventive Principle:

Principle #40Composite materials

3Reliability

If ropes are allowed to move freely to absorb wave forces, then the system is flexible, but friction and kinking occur causing rope damage and mussel loss

Engineering Contradiction:

Improverope durabilityVSAvoidmovement flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system changes the physical parameters of the rope by applying anti-friction coatings or using specially treated ropes with reduced surface friction. This parameter modification allows the ropes to move flexibly to absorb wave forces while minimizing friction-induced damage and kinking, thereby maintaining both durability and flexibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system incorporates cushioning elements or tensioning devices that pre-absorb and distribute the forces before they can cause damage to the ropes. By providing this protective cushioning in advance, the ropes can move freely to adapt to wave forces without suffering from excessive friction or kinking that would lead to damage

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
