Diving Gear Air Duct Design for Rotational Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diving apparatuses experience undesired rotation and discomfort due to pulling forces transmitted through the air-supply line, which can lead to entanglement issues and decreased diving performance, especially at greater depths.
Innovation Solution
The diving apparatus features an air duct design that allows air to flow from the interior-space end to the interior-space beginning, positioning the air-supply line port at the interior-space end, reducing rotational forces and distributing pulling forces closer to the diver's center of gravity, along with a quick-lock fitting for emergency detachment and a stiffening element to redirect forces to the pelvis for improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air-supply line is connected to the housing in the region of the interior-space beginning and routed over the shoulders of the diver, then the air can be supplied to the diver, but the pulling forces acting on the air-supply line cause the diver to rotate out of the ideal horizontal diving position
Solution Approach 1:
The patent changes the spatial dimension of the air-supply line connection by moving the port from the interior-space beginning (top region) to the interior-space end (bottom region) of the housing. This dimensional relocation allows the air-supply line to be routed through water rather than over the diver's shoulders, fundamentally changing the force transmission path and eliminating the rotational moment that caused the diver to rotate out of position.
2Productivity
If the air-supply line is routed over the shoulders of the diver, then the air can be supplied, but the pulling forces must be actively worked against by the diver, decreasing diving performance
Solution Approach 1:
The patent extracts the air-supply line connection from the shoulder region and relocates it to the bottom region of the housing. This extraction removes the source of the harmful pulling forces from the diver's upper body, eliminating the need for the diver to actively work against rotational forces and thereby improving diving performance.
3Stability of the object's composition
If the air-supply line connection is moved to the interior-space end region, then pulling forces are distributed closer to the center of gravity reducing rotation, but air flow from the interior-space end to the interior-space beginning must be ensured
Solution Approach 1:
The patent introduces an air duct as an intermediary component that facilitates air flow from the interior-space end region (where the air-supply line port is now located) to the interior-space beginning region (where the breathing line connects). This intermediary structure resolves the conflict between relocating the port for stability and maintaining proper air flow paths.
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
This design minimizes rotational forces, enhances diving comfort by distributing pulling forces more evenly, and facilitates rapid emergency separation of the air-supply line, improving overall diving performance and safety.
Implementation Method 1
in the event of an overpressure caused by surrounding water, the flexible part is pressed into the interior space, with reduction of the pump volume
Implementation Method 2
the flexible part can be pulled out of the interior space against the overpressure by muscle power of the diver and with increase of the pump volume, in order to suck in air

AI summary
Diving gear includes an air pump having a rigid housing with an interior space and an opening closed by a bag-like flexible part to form a variable pump volume delimited by the housing and the flexible part. The air pump is configured so that, if surrounding water causes positive pressure, the flexible part is pressed into the interior space, thus reducing the pump volume, and, at least in sections, lies against a housing inner wall in an interior space contact portion. A diver can pull the flexible part out of the interior space counter to the positive pressure, thus increasing pump volume. An air duct is configured so that, during the suction, air flows from an interior space end region toward a start of the interior space at least into a maximum height region, preferably into the interior space start region, and into the interior space.
