Maritime Hatch Double Hinge Enclosed Waterproof Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional maritime hatches suffer from corrosion and mechanical failure due to exposure to marine environments, leading to loss of friction and watertight seals, which compromises their functionality and lifespan.
Innovation Solution
A two-way maritime hatch design where articulating components are enclosed within a waterproof seal when closed, utilizing a double hinge system with elastic gaskets for friction and a locking mechanism that protects components from corrosion, allowing for easy maintenance and field repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge is mounted externally on the hatch, then the hatch can be opened and closed, but the hinge components are exposed to the marine environment causing corrosion and mechanical failure
Solution Approach 1:
The hinge components are nested within the hatch structure itself. The hinge pin is received within a hinge bracket that is mounted to the hatch, and the hinge bracket is in turn received within a recess in the hatch. This nesting arrangement protects the hinge components from direct exposure to the marine environment while maintaining their mechanical function.
Solution Approach 2:
A waterproof seal acts as an intermediary between the hinge components and the marine environment. The seal is compressed between the hinge bracket and the hatch surface, creating a barrier that prevents water and corrosive elements from reaching the hinge components, thereby eliminating corrosion while allowing the hinge to function.
2Ease of repair
If the hinge components are exposed to the environment, then access and maintenance are easier, but the components corrode and lose friction and sealing
Solution Approach 1:
The hinge components are nested within the hatch structure with the hinge pin received in the hinge bracket, which is received in a recess in the hatch. This nested arrangement protects components from corrosion while maintaining accessibility for maintenance through the designed opening mechanisms.
Solution Approach 2:
The waterproof seal serves as an intermediary that isolates the hinge components from the marine environment. By compressing the seal between the hinge bracket and hatch surface, the components are protected from corrosion while remaining accessible for maintenance through the hatch design.
3Stability of the object's composition
If a friction hinge is used to maintain window position, then the window can be held in desired orientation, but the friction mechanism is exposed to corrosion causing loss of friction
Solution Approach 1:
The friction hinge mechanism is nested within the hatch structure. The hinge pin is received within the hinge bracket, which is received within a recess in the hatch, creating a protected environment for the friction mechanism that prevents corrosion while maintaining its ability to hold the window in desired positions.
Solution Approach 2:
The waterproof seal acts as an intermediary barrier between the friction hinge mechanism and the marine environment. The seal is compressed between the hinge bracket and hatch surface, protecting the friction components from corrosion while allowing the mechanism to maintain window position stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the lifespan of the hatch by preventing corrosion, maintains a watertight seal, and allows for easier maintenance and repair by keeping components within a weatherproof environment, while providing improved airflow and functionality with bi-directional opening capabilities.
Implementation Method 1
The friction can be adjusted by inserting a thin tool into a bore hole radially disposed in each body to counter rotate the elements
Implementation Method 2
When the hatch is closed, the gasket is compressed, forming a watertight seal

AI summary
A two-way openable maritime hatch in which the articulating components that open the hatch, and hold it in an open position, are enclosed within a waterproof seal of the hatch when in closed position. The design uses a double hinge structure, which facilitates opening the hatch in either a forward- or aft-facing position. Elastic gaskets may be used to hold the hatch open in specific positions or at specific angles. Each of the hinge systems are independently operable.
