Jet Board to PWC Conversion Module Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and maintenance requirements of personal watercraft (PWCs), along with environmental concerns and storage challenges, make them less accessible and sustainable for recreational use.
Innovation Solution
A method to convert a jet board into a PWC by attaching a detachable add-on module that secures the jet board, utilizing its propulsion system and allowing for easier handling and storage, without additional propulsion, thus reducing environmental impact and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a personal watercraft is purchased and used for recreational activities, then water sports enjoyment is achieved, but high purchase cost, maintenance cost, and storage complexity occur
Solution Approach 1:
The system is divided into two separable components: a jet board with propulsion system and an add-on module with seating and console. These can be stored separately or combined, reducing storage space requirements compared to a complete PWC.
Solution Approach 2:
The jet board and add-on module are combined to form a functional PWC when needed. The add-on module attaches to the jet board, merging propulsion capabilities with seating and control features.
2Ease of operation
If a personal watercraft is purchased and used for recreational activities, then water sports enjoyment is achieved, but high maintenance costs and time consumption occur
Solution Approach 1:
The maintenance system is segmented into two parts: the jet board requires minimal maintenance typical of electric propulsion systems, while the add-on module has no propulsion components requiring maintenance. This divides maintenance responsibilities and reduces overall complexity.
Solution Approach 2:
The add-on module is designed as a simpler, less expensive component compared to a complete PWC. If maintenance is needed, only the add-on module requires attention, not the entire propulsion system.
3Ease of operation
If a personal watercraft is purchased and used for recreational activities, then water sports enjoyment is achieved, but negative environmental impact occurs through oil and fuel leaks
Solution Approach 1:
The traditional internal combustion engine is replaced with an electric propulsion system. This substitution eliminates oil and fuel leaks, removing the primary source of environmental pollution associated with conventional PWCs.
4Ease of operation
If a personal watercraft is purchased and used for recreational activities, then water sports enjoyment is achieved, but transportation requires bulky trailers and vehicles with towing capacity
Solution Approach 1:
The system is segmented into a jet board and a separate add-on module that can be transported independently. The add-on module is lightweight and can be carried separately, eliminating the need for bulky trailers and high-capacity towing vehicles.
Solution Approach 2:
The add-on module is designed to attach to the jet board, transforming two separate transportable objects into a combined watercraft only when needed at the water's edge. This dimensional transformation from separate components to integrated vehicle occurs only in the water environment.

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 where 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.
