Curved Diving Weight with Two-Finger Aperture for Emergency Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diving weights and systems fail to provide quick and easy removal in emergency situations due to clamping forces from vest pockets, especially for divers with larger torsos or when wearing gloves, as they often have single finger holes and linear shapes that hinder weight dropping.
Innovation Solution
A curved diving weight with an elongated aperture designed for two fingers and a high friction surface to facilitate leverage and grip, allowing for easier removal from vest pockets, addressing the clamping issues and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single finger hole is provided in the diving weight, then the weight can be removed, but the removal is difficult when divers wear gloves or have larger torsos due to clamping forces
Solution Approach 1:
The single circular aperture is segmented into multiple elongated apertures arranged in a pattern. This segmentation allows multiple fingers to be inserted simultaneously, distributing the gripping force and enabling easier weight removal even when wearing gloves or under clamping forces from vest pockets.
Solution Approach 2:
The aperture design transitions from a single circular opening (zero-dimensional point access) to multiple elongated openings arranged in a two-dimensional pattern. This dimensional change allows fingers to approach from multiple angles and positions, facilitating better grip and leverage for weight removal.
2Ease of operation
If a linear shape is used for the diving weight, then the weight can be easily manufactured, but the weight is difficult to remove from vest pockets due to clamping forces on larger torsos
Solution Approach 1:
The weight transitions from a linear rectangular shape to a curved configuration that conforms to the torso contour. This curvature allows the weight to follow the natural curve of the body, reducing clamping forces from vest pockets and enabling easier removal, particularly for divers with larger torsos.
3Ease of operation
If a smooth surface is provided on the diving weight, then the weight can be easily coated and finished, but the weight is difficult to grip under stress or when wearing gloves
Solution Approach 1:
The surface transitions from uniformly smooth to having localized textured regions. The textured areas provide enhanced friction and grip points where fingers contact the weight, while other areas may remain smooth for coating purposes. This local differentiation improves grip capability without completely sacrificing manufacturability.
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 curved design and two-finger aperture enable effective weight removal even under stress, reducing the likelihood of slipping and improving emergency ascent capabilities.
Implementation Method 1
The outer surface of the weight is rough textured to provide a high friction surface for maximizing ability to grip the weight when forcibly removing it from its pouch in an emergency.

AI summary
A diving weight apparatus has a solid, body with a curved outer conformation. An elongated aperture extends through the body between a front and a back surfaces. The elongated aperture is large enough to accept two fingers of a person's hand therein when the two fingers are arranged in side-by-side positions. A pouch accepts the body and is likewise curved. A diving vest accepts the pouch an is likewise curved.
