Inflatable Swim Fin with Integrated Buoyancy Bladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swim fin devices do not provide both enhanced propulsion and buoyancy, and they lack the ability to be selectively inflated or deflated and folded for storage.
Innovation Solution
An inflatable swim fin apparatus with a foot pocket, a fin blade portion featuring an inflatable bladder, and a foldable design that allows for storage when deflated, enabling enhanced thrust, buoyancy, and user-controlled inflation through a manual inflation valve system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional swim fin devices are used, then propulsion is provided, but buoyancy is not enhanced
Solution Approach 1:
The patent combines the propulsion function of swim fins with the buoyancy function of flotation devices into a single integrated apparatus. The fin blade and inflatable bladder are merged into one structure, allowing the device to simultaneously provide both thrust and buoyancy support to the user.
Solution Approach 2:
The swim fin apparatus is designed to perform multiple functions: it provides propulsion through the fin blade while simultaneously offering buoyancy support through the inflatable bladder. This multi-functional design eliminates the need for separate propulsion and buoyancy devices.
2Strength
If swim fins are made rigid for durability, then strength is improved, but foldability for storage is lost
Solution Approach 1:
The bladder is designed to transition between inflated and deflated states, dynamically changing the structure's properties. When inflated, it provides structural support and rigidity; when deflated, it allows the fin to be folded compactly for storage and transport.
Solution Approach 2:
The bladder is constructed from flexible material that can be inflated to provide structural support and then deflated to enable folding. This flexible shell structure allows the fin to switch between rigid and compact states as needed.
3Adaptability or versatility
If an inflatable bladder is added to provide buoyancy, then versatility is improved, but device complexity increases
Solution Approach 1:
The bladder is integrated into the fin blade structure itself, merging the buoyancy function with the propulsion structure. This integration reduces the number of separate components and simplifies the overall device while adding the buoyancy capability.
