Solution Overview

Problem

Existing buoy systems for marine hoses are not easily adjustable to accommodate different products of varying densities, leading to potential premature failure and requiring external assistance, such as divers, to adjust buoyancy configurations.

Innovation Solution

A buoy device comprising a shell unit and an inflatable/deflatable bladder unit, allowing for adjustable buoyancy without the need for external help, with two separate bladder elements for redundancy and protection, and a control system for precise fluid management through openings and pressure relief valves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If permanent buoy systems are used, then the hose can maintain stable buoyancy configuration, but the system cannot be easily adjusted to accommodate different product densities and requires divers for modification

Engineering Contradiction:
Improveadjustability to different product densitiesVSAvoidcomplexity of adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The buoy system transitions from a static permanent configuration to a dynamic adjustable system. The bladder units can be inflated or deflated to change buoyancy levels, allowing the hose to adapt to different product densities and operational requirements without requiring physical modification or diver intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The buoyancy parameters are made variable through inflatable bladder units. By changing the inflation state of the bladders, the overall buoyancy of the hose system can be adjusted to match different product densities, replacing fixed buoyancy configurations with可调 parameters.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If permanent buoy systems are used, then the hose structure is stable, but external assistance such as divers is required to adjust buoyancy configuration

Engineering Contradiction:
Improveease of buoyancy adjustmentVSAvoidtime for diver intervention
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The buoy system is designed to be self-adjustable through inflatable bladder units that can be inflated or deflated using standard equipment. This eliminates the need for diver intervention and external assistance, allowing operators to adjust buoyancy configuration independently and immediately.

Inventive Principle:
Principle #25Self-service

3Reliability

If single bladder unit is used, then the device structure is simple, but the risk of complete failure upon puncture is high

Engineering Contradiction:
Improveredundancy against puncture failureVSAvoidcomplexity of multi-bladder structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The buoy system is divided into multiple independent bladder units distributed along the hose. Each bladder operates independently, so that a puncture in one bladder does not compromise the entire system. The segmented structure provides redundancy and continues to provide buoyancy through remaining intact bladders.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates redundant bladder units as a preventive measure against failure. By having multiple bladders instead of a single unit, the system is prepared in advance to withstand puncture damage, ensuring continued operational reliability even when one bladder is compromised.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
