Solution Overview

Problem

Hatch covers from ships often need to be removed and stored on docks, breakwaters, or rafts during loading and unloading operations, occupying valuable space that could be used for other critical activities such as cargo handling and equipment transfer.

Innovation Solution

A system comprising a crane with a base integrated into its body to stack and store hatch covers, allowing them to be removed from ships, transported, and returned without needing external storage on docks or rafts, utilizing a gantry crane with an elevated bridge and lateral horizontal beams for support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If hatch covers are removed from ships and stored on docks, breakwaters, or rafts, then they can be easily accessed and stored, but they occupy valuable operational space that could be used for cargo handling and equipment transfer

Engineering Contradiction:
Improveease of hatch cover storageVSAvoidcargo handling efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The invention merges the hatch cover storage function with the crane structure by integrating a base into the crane body. This combination allows the crane to serve dual purposes: loading/unloading cargo and storing hatch covers, thereby eliminating the need for separate storage areas on docks while maintaining operational efficiency

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The crane is designed with multi-functionality by incorporating a base that can store hatch covers. This universal structure allows the same equipment to perform both cargo handling operations and hatch cover storage, maximizing the utilization of port space and equipment

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If hatch covers are stored on docks or rafts, then they are readily accessible, but the area is unavailable for other critical port operations

Engineering Contradiction:
Improvehatch cover accessibilityVSAvoidport operational area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The invention combines the storage function with the crane structure, merging two separate functions (cargo handling and hatch cover storage) into one integrated system, thereby preserving port operational area while maintaining ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention utilizes the vertical dimension by stacking hatch covers on the crane base, transitioning from horizontal space occupation on docks to vertical space utilization on the crane structure, thereby preserving valuable horizontal port operational area

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