Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal flotation devices, such as inflatable pontoons and fishing kayaks, face issues with punctures, transportability, and stability, as well as being sensitive to temperature and pressure changes.
Innovation Solution
A modular flotation device composed of interchangeable and interlocking rigid pontoon sections, which can be easily assembled and disassembled for transport and storage, featuring identical connection profiles for quick assembly and secure mating, along with an intermediate frame module and adjustable components for stability and propulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If inflatable pontoons are used, then the device is lightweight and portable, but it is susceptible to punctures and pressure variations
Solution Approach 1:
The pontoon is divided into multiple sealed compartments within a single rigid structure. Each compartment is independently sealed, so if one compartment is punctured, the others maintain buoyancy. This segmentation approach resolves the contradiction by providing puncture resistance through structural division while keeping the overall device lightweight at 15 lbs.
Solution Approach 2:
The patent uses a rigid hollow structure with integrated air chambers instead of flexible inflatable membranes. The rigid shell provides inherent puncture resistance while the internal air chambers provide buoyancy, eliminating the need for thin flexible films that are prone to punctures.
2Reliability
If rigid pontoon boats are used, then puncture and pressure variation problems are solved, but transportability becomes difficult
Solution Approach 1:
The rigid pontoon is segmented into multiple detachable sections that can be separated for transport. The connection and disconnection mechanisms allow the pontoon to be broken down into manageable pieces that fit in vehicle trunks, then quickly reassembled at the destination. This resolves the transportability issue while maintaining the puncture-resistant rigid structure.
3Quantity of substance
If fishing kayaks are used, then carrying capacity is increased, but transportability and cost increase, and stability decreases
Solution Approach 1:
The pontoon boat uses a modular design with detachable sections and configurable seating arrangements. The segmented structure allows the boat to be disassembled for easy transport in standard vehicles, while the modular configuration enables flexible seating and storage arrangements to accommodate multiple passengers and gear, achieving high carrying capacity without sacrificing transportability.
