Solution Overview

Problem

Current wreck buoys are difficult to install quickly and accurately in marine accident scenarios due to their weight, requiring significant manpower and equipment, and existing systems struggle to immediately mark new hazards, posing safety risks and delaying rescue operations.

Innovation Solution

An auto-release buoy system that automatically deploys a small wreck buoy from a ship upon detecting predetermined water pressure, featuring an auto-reel chain and auto-lighting lantern, allowing immediate and accurate marking of accident locations with reduced manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If standard wreck buoys are installed manually, then the marking function is achieved, but the installation time is excessive and manual labor requirements are high

Engineering Contradiction:
Improveinstallation timeVSAvoidmanual labor requirement
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The wreck buoy is pre-loaded onto the ship along with the chain and releasing mechanism. All components are prepared and positioned before the accident occurs, enabling immediate deployment without manual assembly or installation operations after the incident.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically deploys the wreck buoy through self-activating mechanisms. The buoy releases itself from the ship when the chain becomes taut upon water contact, and the buoyancy automatically propels it to the surface without requiring any manual intervention for installation or operation.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual installation of wreck buoys is performed, then positioning accuracy can be controlled, but the response speed to marine accidents is insufficient

Engineering Contradiction:
Improvepositioning accuracyVSAvoidresponse speed
Core Design Contradiction:
Measurement precisionVSSpeed

Solution Approach 1:

The wreck buoy system is pre-positioned on the ship at known locations. The chain length is predetermined to reach the water surface from the buoy's deployed position, ensuring that the accident location is marked with sufficient positional accuracy while enabling immediate automatic deployment upon contact with water.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual mechanical installation process is replaced by an automatic mechanical deployment system triggered by water contact. The tension in the chain automatically activates the releasing mechanism, substituting human-operated mechanical installation with an autonomous mechanical response system.

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

3Productivity

If automatic deployment is implemented, then response speed is improved, but the system complexity increases

Engineering Contradiction:
Improvedeployment efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic deployment system is divided into three independent functional segments: the wreck buoy with buoyancy chamber, the chain with releasing mechanism, and the anchoring weight. Each segment performs a specific function and can be independently analyzed, maintained, and replaced, reducing overall system complexity despite the automated functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The chain serves as an intermediary element that connects the wreck buoy to the ship and water. It transmits the force of water contact to activate the releasing mechanism and simultaneously provides the anchoring function when the buoy reaches the surface, simplifying the control system by using a single component for multiple functions.

Inventive Principle:
Principle #24Intermediary (Mediator)
