Surfboard Fin Seat With Curved Plate Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surfboard fin and socket structures are prone to damage from wave impacts, making maintenance time-consuming and inconvenient, with issues of looseness and difficulty in replacement.
Innovation Solution
A surfboard design where the fin seat and fin box are secured as an integral structure using screw members with curved plates and outward protruded portions that engage into circular slots, allowing for easy assembly and disassembly by rotating the screw members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fin or socket is made as a traditional separate structure, then the surfboard can be easily manufactured, but the fin or socket is prone to damage from wave impacts and maintenance is time-consuming
Solution Approach 1:
The fin seat is designed as a separable component that can be detached from the fin box, allowing the fin seat to be replaced independently when damaged. This segmentation enables quick maintenance by replacing only the damaged fin seat rather than the entire fin assembly, significantly reducing maintenance time while maintaining durability through replaceable components.
Solution Approach 2:
The invention allows the fin seat to be discarded (removed) from the fin box when damaged and a new fin seat to be installed. The fin box itself is retained and reused, recovering the valuable structural component while replacing only the damaged socket portion, thus reducing maintenance time and material waste.
2Stability of the object's composition
If the fin seat is firmly secured to the fin box, then the structure is stable during surfing, but the fin seat becomes hard to replace when damage occurs
Solution Approach 1:
The connection between fin seat and fin box is designed to be dynamic rather than static. The fin seat can be securely locked during surfing through threaded engagement of screw members, providing stability. When maintenance is needed, the screw members can be undone and the fin seat easily removed. This dynamic connection allows the system to switch between stable operation and easy maintenance modes.
Solution Approach 2:
Screw members act as intermediary elements between the fin seat and fin box. These screw members with curved plates provide the locking mechanism that secures the fin seat during use, but can be easily removed to allow fin seat replacement. The intermediary screw members enable both stable connection and easy disassembly without requiring permanent bonding.
3Ease of repair
If traditional fin or socket maintenance is performed, then damaged parts can be fixed or replaced, but the maintenance work is quite time consuming or inconvenient
Solution Approach 1:
The fin seat is segmented as a separate replaceable component from the fin box and surfboard body. When damage occurs, only the fin seat needs to be removed and replaced, rather than repairing the entire fin assembly or socket structure. This segmentation dramatically reduces maintenance time and complexity by isolating the replaceable component.
Solution Approach 2:
The fin seat can be extracted (removed) from the fin box using the screw member mechanism. This extraction capability allows the damaged fin seat to be taken out and replaced with a new one quickly, making maintenance convenient and time-efficient compared to traditional methods that require more extensive disassembly or repair procedures.

AI summary
It includes a surfboard body, a fin box, a fin seat, and multiple screw members. The fin box is embedded with the surfboard body and has a box recess and box holes. Each box hole has several circular slots. The fin seat has a fin and securing portions. Each securing portion has several curved plates for enclosing a receiving space. Each screw member has a tapered portion with an outer threaded portion. When the screw member is rotated in, these curved plates will gradually expand outwards and force the outward protruded portions engaging into the corresponding circular slots. So, the fin seat and the fin box are engaged together. When the screw member is rotated out, the fin seat and the fin box can be separated. About this invention, the fin seat and the fin box can be firmly secured together. Plus, its fin seat can be replaced easily.
