Solution Overview

Problem

Existing ship's holds for storing tenders face issues with hydraulic control systems that cause environmental pollution due to leakage and are complex, heavy, and costly, while also presenting obstacles during tender storage and launch operations.

Innovation Solution

A ship's hold equipped with a translator-elevator device that uses electromechanical control means, comprising support and guide structures, carriages, and tackle systems with electric gear motors, allowing for vertical and horizontal movement of tenders without hydraulic systems, thus preventing pollution and simplifying the structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hydraulic control means are used to move the tender, then the tender can be moved from inside to outside of the ship, but hydraulic leaks cause environmental pollution and the system becomes complex and heavy

Engineering Contradiction:

Improvetender movement capabilityVSAvoidhydraulic control system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the hydraulic control system with an electromechanical system consisting of electric motors, gear mechanisms, and winches. The electric motor drives a gear mechanism that operates the winch to move the tender, eliminating hydraulic pipes, fluid, and associated leakage risks while reducing overall system complexity and weight.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the hydraulic control means from the system entirely. Instead of using hydraulic pressure to move the tender, the design uses purely mechanical and electrical components (electric motors, gears, winches) that can be easily installed and maintained without the complexity of hydraulic infrastructure.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If hydraulic control means are used to move the tender, then the tender can be moved from inside to outside of the ship, but hydraulic leaks cause environmental pollution

Engineering Contradiction:

Improvetender movement capabilityVSAvoidenvironmental pollution from hydraulic leaks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent eliminates the harmful hydraulic system entirely and replaces it with a cleaner electromechanical system. The removal of hydraulic fluid and pipes eliminates the risk of environmental pollution from leaks, converting a harmful system into a safe one.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If hydraulic control means are used to move the tender, then the tender can be moved from inside to outside of the ship, but the system becomes heavy and costly

Engineering Contradiction:

Improvetender movement capabilityVSAvoidcontrol system weight

Core Design Contradiction:

Ease of operationVSWeight of stationary object

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses simpler, less expensive electromechanical components (electric motors, gears, winches) instead of complex hydraulic systems. These components are generally lighter, cheaper to install, and easier to replace if needed, reducing both initial cost and long-term maintenance expenses.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Reliability

If a hatch is hinged with respect to the wall to open and close the doorway, then the doorway can be sealed, but the hatch becomes an obstacle for tender storage and launch operations

Engineering Contradiction:

Improvedoorway sealingVSAvoidtender storage and launch operations

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent makes the hatch dynamic by connecting it to the movable platform that carries the tender. As the platform moves the tender in and out of the hold, the hatch automatically follows, opening when the tender needs to be launched and closing when the tender is stored. This eliminates the obstacle problem while maintaining sealing capability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent merges the hatch mechanism with the tender movement system. The hatch is integrated into the platform structure and moves simultaneously with the tender, combining the sealing function with the tender operation function. This coordination ensures the hatch is open during launch operations and closed during storage, eliminating conflicts between sealing and operation.

Inventive Principle:

Principle #5Merging (Combining)
