Watersport Board Fin Adapter With Nested Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watersport boards face challenges in securing the fin assembly effectively, which can lead to instability and reduced control during use, as the fin and fin box region are prone to damage from loads and forces applied during water sports.
Innovation Solution
The watersport board design incorporates a baseplate with embedded female fasteners and a fin adapter system, featuring a tough connection block made of a copolymer foam material, along with male and female fasteners made of non-foam plastic, to securely attach the fin assembly, providing enhanced stability and protection against damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple fin assembly structure is used, then the device complexity is reduced, but the reliability of securing the fin assembly is compromised
Solution Approach 1:
The fin adapter is nested within the fin box receptacle, the baseplate is nested within the board body, and multiple fasteners are nested within the baseplate holes. This nested structure allows multiple functional components to be integrated in a compact arrangement, improving securing reliability without proportionally increasing overall device complexity
Solution Approach 2:
The fin assembly is segmented into distinct functional components: the fin adapter (with adapter body and extension), the baseplate (with first and second holes), and multiple fasteners. This segmentation allows each component to be optimized for its specific function while working together as a integrated system, resolving the contradiction between reliability and complexity
2Stability of the object's composition
If the fin assembly is securely fastened, then the stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The baseplate is pre-attached to the board body before the fin adapter is installed. The fasteners are positioned through the baseplate holes in advance, creating a prepared structure that simplifies the final assembly of the fin adapter. This preliminary preparation ensures stability while maintaining manufacturing ease through sequential assembly
Solution Approach 2:
The baseplate serves as an intermediary component between the board body and the fin adapter. It provides a stable mounting surface with pre-positioned holes for fasteners, mediating the connection between the structural board body and the functional fin adapter, thereby simplifying the overall manufacturing process

AI summary
A watersport board includes a board body, two female fasteners, a baseplate, a fin adapter, a fin and two male fasteners. The board body defines a receptacle. The female fasteners are embedded in the board body. Each female fastener has a receiving hole. The baseplate is attached underneath the board body. The baseplate has a first bore and two second bores. The fin adapter has an adapter body and an extension laterally extending from the adapter body. The adapter body passes through the first bore of the baseplate and is engaged in the receptacle of the board body, and the adapter body has a cavity. The fin has a base portion received in the cavity of the adapter body. Each male fastener has one end connected to the extension of the fin adapter, and the other end passing through the second bore of the baseplate and being engaged in the receiving hole of the female fastener.
