Solution Overview

Problem

Nautical window perimetrical frames fail to prevent water stagnation and humidity, leading to bad smells and frequent maintenance needs, which are physically demanding and provide only temporary relief.

Innovation Solution

The perimetrical frame features through micro-openings in laminar gaskets and staggered holes in the shaped element, creating a tortuous labyrinth that allows air passage while preventing water entry, with a second laminar gasket acting as a barrier to water propagation and evaporation, reducing moisture and mist formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the perimetrical frame uses a closed frame-like shape with sealing means to prevent water entry, then sealing performance is improved, but water stagnation and humidity occur inside the compartment

Engineering Contradiction:
Improvesealing performanceVSAvoidwater stagnation and humidity
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies porous or perforated sealing means (laminar gaskets with micro-openings) that allow vapor and air passage while blocking liquid water. The gaskets contain numerous small holes that create a tortuous path for water droplets, enabling moisture evaporation and ventilation while maintaining water tightness, thus resolving the contradiction between sealing and preventing water stagnation.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The sealing means are segmented into multiple laminar gaskets with distributed micro-openings rather than a continuous solid structure. This segmentation creates multiple pathways for air flow while maintaining water barrier functionality, allowing the compartment to ventilate and dry while remaining sealed against rain and waves.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If the perimetrical frame uses traditional sealing means to prevent water entry, then water protection is improved, but bad smells and mist formation occur due to poor ventilation

Engineering Contradiction:
Improvewater protectionVSAvoidbad smells and mist
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The laminar gaskets are designed as porous materials with controlled micro-openings that selectively allow gas molecules (air, vapor, odor-carrying molecules) to pass through while blocking liquid water droplets. This enables continuous ventilation to prevent bad smells and mist formation while maintaining water protection.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The micro-openings in the gaskets act as intermediaries that mediate between the need for ventilation (to remove bad smells and mist) and the need for water protection. The tortuous path created by the micro-openings allows air exchange while the surface tension and geometry of the openings prevent water penetration.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the perimetrical frame uses a closed sealing structure to prevent water entry, then sealing effectiveness is improved, but maintenance frequency increases due to moisture accumulation

Engineering Contradiction:
Improvesealing effectivenessVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The compartment equipped with porous sealing means performs self-ventilation and self-drying through the micro-openings in the gaskets. Moisture that enters the compartment can evaporate and escape through the same sealing means, eliminating the need for manual intervention to prevent mold and degradation, thus reducing maintenance frequency while maintaining sealing effectiveness.

Inventive Principle:
Principle #25Self-service
