Inflatable Bladder Seals Yacht Hull Openings Below Waterline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Yachts are at risk of sinking due to water ingress through openings below the waterline, especially when bilge pumping systems fail or during maintenance, as existing solutions are inadequate for rapid and effective sealing in emergency conditions.
Innovation Solution
A yacht preserver system comprising an inflatable bladder and a gas canister, where the bladder is inflated using a pressurized gas source to seal openings, facilitated by a handle and activation device, allowing quick deployment to prevent water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bilge pumping system is used to remove water from the yacht, then the risk of sinking is reduced, but in the event of catastrophic failure of the pumping system, the influx of water may sink the yacht
Solution Approach 1:
The patent applies preliminary anti-action by providing a passive sealing system (float valve or inflatable bladder) that automatically activates to prevent water ingress before the pumping system fails catastrophically. The float valve rises with incoming water to close the opening, or the inflatable bladder can be deployed to seal the opening, creating a preliminary protective barrier that does not depend on the pumping system being operational.
Solution Approach 2:
The patent implements beforehand cushioning by installing a backup sealing mechanism that provides an additional layer of protection against water ingress. This secondary system (float valve or inflatable bladder) acts as a cushion or safety net that prevents catastrophic failure if the primary pumping system fails, thereby cushioning against the harmful effect of water ingress.
2Reliability
If openings in the hull are sealed to prevent water entry, then the yacht is protected from sinking, but rapid deployment is needed in emergency conditions
Solution Approach 1:
The patent applies preliminary action by pre-positioning the sealing system (float valve or inflatable bladder) at the opening location before any emergency occurs. The float valve is already installed and will automatically activate when water rises, while the inflatable bladder is pre-mounted and can be quickly inflated using a CO2 cartridge or other gas source, eliminating the need for complex assembly or retrieval during an emergency.
Solution Approach 2:
The patent implements self-service through the float valve mechanism, which automatically activates in response to water ingress without requiring human intervention. The float rises with incoming water and automatically closes the opening. For the inflatable bladder, the system can be designed to automatically inflate upon detection of water ingress or with a simple manual activation, minimizing the time and effort required for deployment.
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 system effectively and rapidly seals openings below the waterline, reducing the risk of sinking by providing a reliable and easy-to-use solution for emergency situations and maintenance needs.
Implementation Method 1
The inflator device may include a gas canister, for example, a carbon dioxide canister, and a bladder (for example, an air bag) configured to expand under the influence of gas provided by the gas canister
