Quick-Release Boat Fender Securing Device with Adjustable Nylon Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Boaters face challenges in efficiently securing boat fenders due to difficulties in adjusting and tying rope knots, which can lead to time wastage and risk of the fender detaching, necessitating a quick, easy, and secure method for positioning fenders.
Innovation Solution
A quick-release securing device featuring a nylon strap with an adjustable openable loop and snap hook, allowing for easy attachment and detachment of fenders, utilizing a buckle for loop closure and sliders for length adjustment, along with a supplemental strap for additional attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rope with knots is used to secure the fender, then the fender can be adjusted to different positions, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent replaces the traditional rope-and-knot mechanical system with a webbing strap system featuring a plastic buckle and slider mechanism. This substitution transforms the complex knot-tying process into simple buckling and sliding actions, dramatically reducing adjustment time while maintaining position versatility.
Solution Approach 2:
The invention changes the adjustment mechanism from knot placement (discrete positions) to continuous slider movement along the webbing strap. This parameter change allows smooth, continuous adjustment of fender height and positioning without the time-consuming process of retving knots at different locations.
2Reliability
If traditional rope knots are used, then the fender can be secured, but there is risk of the rope detaching and the fender being lost
Solution Approach 1:
The patent replaces unreliable knot-tying with a positive-latch plastic buckle system that mechanically secures the webbing strap. This mechanical substitution eliminates the skill-dependent nature of knot-tying while providing more reliable attachment, as the buckle's latch mechanism prevents accidental detachment.
Solution Approach 2:
The quick-release mechanism allows the fender to be secured and released without requiring specialized knot-tying skills. The system is self-explanatory and self-sufficient, requiring only simple buckling and un-buckling actions that any user can perform reliably.
3Productivity
If an adjustable strap system is used, then quick adjustment is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the securing device into distinct functional segments: a webbing strap body, a plastic buckle for primary attachment, and a slider mechanism for length adjustment. This segmentation allows each component to perform its specific function independently, simplifying the overall design while enabling quick adjustment capabilities.
Solution Approach 2:
The invention introduces dynamic elements (the movable slider along the webbing strap) that allow the device to adapt to different fender positions and boat configurations. This dynamic capability enables quick adjustment without requiring multiple separate devices or complex assembly procedures.

AI summary
A quick-release securing device is constructed of nylon strap having an openable loop at one end, and snap hook at the other end. The distance between the openable loop and the snap hook, and the circumference of the openable loop, is adjustable. The loop can be opened and closed using a buckle. A supplemental strap may be employed for releasably attaching items, such as boat fenders, to the securing device.
