Kayak Leverage Strap Using Scupper Hole Anchors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for aiding standing and sitting in sit-on-top kayaks require permanent alterations to the vessel or are temporary, necessitating special tools and skills, limiting accessibility for older or less physically agile users.
Innovation Solution
The EaZup device utilizes pre-molded scupper holes in the kayak hull to secure an adjustable 1″ wide nylon strap with slide clasps and rust-resistant hardware, providing leverage without drilling or altering the hull, allowing for semi-permanent installation and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent alterations to the kayak hull are made to install a leverage strap, then the strap provides stable leverage for standing and sitting, but the kayak hull is damaged and installation requires special tools and skills
Solution Approach 1:
The patent introduces scupper plugs as an intermediary component that utilizes existing scupper holes in the kayak hull to anchor the leverage strap. This mediator allows the strap to be securely fastened without drilling new holes or making permanent alterations to the hull, thus providing stable leverage while avoiding damage to the kayak structure
Solution Approach 2:
The patent uses existing scupper holes (which are already molded into the kayak hull) as anchor points for the leverage strap. By copying the function of these pre-existing holes for a new purpose (securing the strap), the invention avoids the need for additional hull alterations while maintaining secure attachment
2Reliability
If permanent alterations to the kayak hull are made to install a leverage strap, then the strap provides stable leverage, but installation becomes complex requiring special tools and skills
Solution Approach 1:
The scupper plugs serve as an intermediary that simplifies installation by utilizing the existing scupper holes in the kayak. This approach eliminates the need for drilling, threading, or complex fastening operations, allowing anyone to install the leverage strap using basic tools and common sense
Solution Approach 2:
The leverage strap system is segmented into separate components: the strap itself, the scupper plugs, and the attachment hardware. This segmentation allows for easy assembly and disassembly without requiring complex installation procedures or specialized skills
3Ease of manufacture
If temporary slip-on solutions are used for the leverage strap, then installation is easy and requires no tools, but the strap lacks sufficient stability and leverage
Solution Approach 1:
The scupper plugs act as an intermediary that provides a secure anchoring mechanism while maintaining ease of installation. The plugs insert into the existing scupper holes and provide firm attachment points for the strap, achieving both stability and ease of installation simultaneously

AI summary
An aid to assist mobility in standing upright from a seated position or inversely to aid in safely reaching a seated position from standing as it applies to the interior of a Sit-On-Top Kayak. Comprised of a nylon strap extending to the user from forward the vessel where it is anchored by a bolt or machine screw passing thru dense rubber based plugs inserted from above and below the deck of the boat utilizing pre-existing “scupper holes”, through holes, molded by various manufacturers into the hull of Sit-On-Top Kayaks. This sandwiches and compresses the plugs thus creating a secure semi-permanent but removeable anchoring point for the nylon strap. This allows for an easy installation with no alterations to the boats hull and provides the necessary leverage to aid in sitting or standing.
