Diver Recovery Bladder Control for Safe Depth-Based Ascent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable life vests for divers do not provide controlled ascent based on depth and duration, which can lead to unsafe diving conditions.
Innovation Solution
An underwater diver recovery system with an inflatable bladder, inflation control mechanism, and control module that determines depth and duration to inflate the bladder for a controlled ascent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inflatable life vests are used, then divers can be recovered from water, but the ascent is not controlled and may be unsafe
Solution Approach 1:
The control module pre-determines the optimal ascent time based on the diver's depth before initiating inflation. This preliminary calculation of ascent parameters ensures safe controlled ascent while avoiding overly complex real-time adjustments during the recovery process.
Solution Approach 2:
The system incorporates depth sensors that continuously monitor the diver's depth and provide feedback to the control module. This feedback mechanism allows the system to adjust inflation timing and duration dynamically, ensuring safe ascent control without requiring complex manual intervention.
2Speed
If inflation is triggered immediately upon depth detection, then response time is reduced, but ascent control is compromised
Solution Approach 1:
The control module performs preliminary calculations of the required ascent time based on the detected depth before triggering inflation. This allows the system to prepare the optimal inflation parameters in advance, ensuring both rapid response and controlled ascent by pre-determining the exact timing and duration needed for safe recovery.
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
Ensures safe and controlled ascents of divers by preventing excessive depth or duration, reducing the risk of diving-related injuries.
Implementation Method 1
The use case for hydrostatic pressure-type vest inflator is someone who wants a vest that inflates itself when a sensor in the vest inflator senses it is submerged
Implementation Method 2
An inflatable bladder configured to be worn by a diver and cause the diver to ascend to a surface of water

AI summary
Disclosed are methods, computer readable medium, and an underwater diver recovery system configured to be worn by a diver. The underwater diver recovery system includes an inflatable bladder. The underwater diver recovery system also includes an inflation control mechanism coupled to the inflatable bladder. The underwater diver recovery system also includes a control module configured to be in communication with the inflation control mechanism. The control module is operable to determine an underwater depth of the diver, and upon determining that the underwater depth exceeds a depth threshold value, cause the inflation control mechanism to inflate the inflatable bladder with a preset amount of gas, and cause the diver to ascend in controlled manner.
