Jet Board to PWC Conversion Using Detachable Add-On Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost, maintenance requirements, and environmental impact of traditional personal watercraft (PWCs) pose challenges for users, including expensive ownership, time-consuming maintenance, and difficult storage and transportation.
Innovation Solution
A method to convert a jet board into a PWC by attaching a detachable add-on module that secures to the jet board using various couplers and mechanisms, allowing the jet board's propulsion system to power the converted PWC without additional propulsion, enabling easier storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a traditional personal watercraft (PWC) is used, then propulsion power and stability are improved, but cost, maintenance requirements, and storage difficulty increase
Solution Approach 1:
The PWC system is divided into two independent segments: a jet board with propulsion system and an add-on module with hull and seat. The jet board provides propulsion power while the add-on module provides stability and riding platform. This segmentation allows users to only own and maintain the essential propulsion component rather than a complete PWC system.
Solution Approach 2:
The jet board serves multiple functions: it provides propulsion for both the jet board alone and the converted PWC configuration. The add-on module can be attached to the jet board to create a PWC experience, and removed when not needed. This multi-functionality reduces overall system complexity and ownership burden.
2Power
If a traditional personal watercraft (PWC) is used, then propulsion power and stability are improved, but maintenance cost and time increase
Solution Approach 1:
By segmenting the PWC into a jet board and a detachable add-on module, the propulsion system remains isolated in the jet board portion. This means maintenance activities are confined to the jet board only, without needing to service the entire PWC system. The add-on module requires no maintenance as it contains no mechanical propulsion components.
3Power
If a traditional personal watercraft (PWC) is used, then propulsion power and stability are improved, but storage and transportation difficulty increase
Solution Approach 1:
The segmented design allows the add-on module to be completely detached from the jet board for storage and transportation. Users can store the compact jet board in a garage or shed, and only attach the add-on module when water access is available. This eliminates the need for large storage spaces and specialized trailers required by traditional PWCs.
Solution Approach 2:
The system transitions between two dynamic configurations: jet board only for storage and transportation, and jet board with add-on module for water use. This dynamic reconfiguration optimizes the system for different operational contexts, improving ease of storage and transportation while maintaining propulsion power and stability when needed.

AI summary
A method to convert a jet board, which may include an electric surfboard, an electric standup paddle board, an electric hydrofoil board, into a personal watercraft (PWC). The method includes attaching an add-on module onto the jet board using grippers. The add-on module provides handles and a seat but does not provide a source of propulsion. The resulting personal watercraft is, instead. driven by the propulsion system of the jet board.
