Propeller Safety Cover Sleeve With Quick-Release Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watercraft propeller accessories do not provide effective protection against cuts from the sharp edges of submerged propellers, posing a risk to swimmers and others in the water.
Innovation Solution
A cover sleeve made of durable material, such as foam, is designed to fit around the propeller, secured by a flexible sheath and strap assembly, ensuring complete coverage and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a propeller cover is installed, then protection against propeller cuts is improved, but the complexity of the device increases
Solution Approach 1:
The propeller cover system is divided into separate components: a flexible cover material layer and a securing structure with straps and buckles. This segmentation allows the cover to be installed and removed easily while providing effective protection when in use.
Solution Approach 2:
The propeller cover utilizes flexible material such as vinyl, plastic, or fabric that can conform to the shape of the propeller. This flexibility allows the cover to provide comprehensive protection while remaining simple in design and easy to install over the propeller blades.
2Reliability
If a secure securing structure is used, then reliability of coverage is improved, but ease of operation deteriorates
Solution Approach 1:
The securing structure employs adjustable straps with buckles that can be dynamically tightened or loosened. This allows the cover to be securely fastened during storage to prevent accidental deployment, while enabling quick removal when the propeller needs to be used by simply unfastening the buckles.
Solution Approach 2:
The cover design allows for easy self-installation and self-removal by the user without requiring tools or assistance. The straps and buckles are positioned and designed to be easily manipulated by hand, enabling quick deployment and removal operations.
