Floating Apparatus Watertight Structure with Absorbent Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating apparatuses are prone to damage and structural compromise due to water ingress, which affects their buoyancy and longevity.
Innovation Solution
A watertight structure comprising a first layer with high strength and a second absorbent layer, often made of superabsorbent polymers, is integrated into the floating apparatus to absorb and compensate for water ingress, enhancing structural strength and watertight performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-layer watertight structure is used, then the structure is simple, but water ingress causes damage and reduced reliability
Solution Approach 1:
The patent applies composite materials by combining a non-absorbent first layer (made of steel, aluminum, concrete, FRP, or their combinations) with an absorbent second layer (made of superabsorbent polymers). This composite structure prevents water ingress damage while maintaining structural integrity, resolving the contradiction between reliability and simplicity.
Solution Approach 2:
The watertight structure is segmented into multiple functional layers: a first non-absorbent layer for structural strength and a second absorbent layer for water absorption. This segmentation allows each layer to perform its specific function, improving overall watertight reliability without excessive complexity.
2Reliability
If no absorbent layer is used, then the structure is simpler, but water ingress directly damages the floating apparatus
Solution Approach 1:
The absorbent second layer acts as an intermediary between the external water environment and the internal structure of the floating apparatus. It absorbs water that penetrates the first layer, preventing direct contact with and damage to the internal components, thus improving water damage resistance.
Solution Approach 2:
The patent converts the harmful effect of water ingress into a beneficial effect by using the absorbent second layer to capture and hold water that penetrates the first layer. This prevents water from reaching critical internal components, transforming potential damage into a controlled absorption process.
3Reliability
If an absorbent layer is added to prevent water damage, then reliability improves, but the structure becomes more complex
Solution Approach 1:
The patent applies local quality by making the first layer non-absorbent (for structural strength) and the second layer absorbent (for water absorption). Each layer has differentiated properties optimized for its specific function, improving buoyancy maintenance through specialized material characteristics.

AI summary
A floating apparatus is provided. The floating apparatus includes a watertight structure. The watertight structure includes a first layer and a second layer. The second layer is in direct contact with the inner surface of the first layer. The second layer is more absorbent than the first layer. The first layer may have high strength. The second layer may absorb liquid. Therefore, both the structural strength and watertight performance of the floating apparatus are enhanced.
