Closed-Loop Watersports Handle That Blocks Limb Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watersports handles with through-holes pose safety risks as users can insert limbs or hands, leading to joint damage and drowning, and lack size adaptability, causing discomfort or inefficiency.
Innovation Solution
A closed-loop handle with a flexible, tear-resistant mesh covering the through-hole, allowing water permeability and preventing limb insertion, designed to fit various user sizes and grip styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a through-hole handle is used, then users can easily grip the handle, but users can insert limbs or hands through the handle causing safety risks
Solution Approach 1:
The patent removes the through-hole from the handle design, extracting the dangerous opening that allows limb insertion. The handle becomes a closed-loop structure where users grip the exterior surface, eliminating the pathway for limbs to pass through while maintaining gripping functionality.
Solution Approach 2:
The patent introduces a mesh material as an intermediary layer covering the former through-hole area. This mesh allows water permeability while blocking limb insertion, serving as a mediator that maintains the beneficial water flow property while preventing the harmful limb insertion risk.
2Ease of manufacture
If a one-size handle is used, then manufacturing is simple, but the handle may not fit all user sizes comfortably
Solution Approach 1:
The patent makes the handle adjustable by introducing a dynamic structure with movable components. The handle can change its dimensions or configuration to accommodate different user sizes, transitioning from a static one-size design to a dynamic adaptive structure.
Solution Approach 2:
The patent enables the handle to change its physical parameters (such as diameter, length, or shape) to suit different users. This could be achieved through adjustable mechanisms or materials that allow the handle to morph between different size configurations.

Function Achieved in This Case
Enhances safety by preventing limb insertion, maintaining grip comfort, and ensuring secure attachment without compromising usability, even in inverted positions.
Implementation Method 1
a flexible but tear and puncture resistant mesh that blocks the through hole. Water is easily able to pass through, but the hands, finger, and limbs of a user

AI summary
A flexible, no through hole, loop handle is disclosed for a watercraft. The customary loop handle through hole is completely closed by a particular, sturdy, flexible, stretchy, mesh, or other puncture resistant, water suited and water permeable fabric. The handle grip portion is a fabric tube enclosing a squeezable foam segment that enables a user to obtain a complete finger overlapped with thumb wrapped grip on the handle. The closed through hole eliminates the risk of a user's hand or other limb segment being intentionally or inadvertently extended through the handle. The mesh fabric is sufficiently flexible to allow a full finger wrapped grip around the fabric tube of the handle such that no aspect of user grip is compromised by virtue of the mesh fabric.
