Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a personal watercraft is equipped with a jet propulsion system, then it can provide powerful propulsion and high speed, but it increases the cost of buying, maintaining, and transporting the watercraft
Solution Approach 1:
The invention divides the personal watercraft into two separate components: a jet board with jet propulsion system and an add-on module. The jet board contains the propulsion system while the add-on module provides the hull structure. This segmentation allows the propulsion system to be reused across different configurations, reducing overall system complexity and cost.
Solution Approach 2:
The jet board is designed to serve multiple functions: it can be used as a standalone jet board for riding, or it can be combined with the add-on module to form a personal watercraft. The propulsion system on the jet board is universal and can power both configurations, reducing the need for duplicate systems and lowering costs.
2Stability of the object's composition
If a personal watercraft is designed with a complete hull and propulsion system, then it can provide stable riding, but it requires bulky storage and transportation infrastructure
Solution Approach 1:
The personal watercraft is segmented into a jet board and a separate add-on module. The add-on module contains the hull structure needed for stable riding, while the jet board provides propulsion. When not in use, these two components can be stored separately, significantly reducing the storage volume compared to a complete assembled watercraft.
Solution Approach 2:
The system transitions between different configurations: the add-on module can be attached to the jet board when stable riding is needed, and detached when storage or transportation is required. This dynamic reconfiguration allows the system to adapt between providing stability and minimizing volume based on operational needs.
3Power
If a personal watercraft uses traditional fuel-based propulsion, then it can provide high power output, but it has negative environmental impact through oil and fuel leaks
Solution Approach 1:
The invention replaces traditional fuel-based mechanical propulsion with an electric propulsion system on the jet board. The electric motor-driven jet pump provides sufficient propulsion power while eliminating fuel storage, fuel lines, and exhaust systems that cause environmental pollution through leaks and emissions.

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.
