Rhode Island Patent of the Month – May 2025
Flux Marine Ltd. has secured U.S. Patent No. 12296934 for a groundbreaking marine propulsion system that promises to redefine electric boating. The patent, titled ‘Dual strut power transmission housing structure of a marine propulsion system’, introduces a novel design that enhances efficiency and cooling in electric outboard motors. This innovation could significantly impact the performance and reliability of electric boats.
Innovative Dual-Strut Design
The patented system features two parallel struts extending from the motor’s main body to the lower unit housing the propeller. Each strut contains an internal channel that houses a portion of the drive belt, effectively transmitting power from the motor to the propeller. This configuration not only streamlines the power transmission but also contributes to the structural integrity of the propulsion system.
Integrated Thermal Management
A key aspect of this design is the incorporation of a thermal circuit within the struts and lower unit. This circuit allows coolant to flow bidirectionally, efficiently dissipating heat generated during operation. By integrating the cooling system into the structural components, the design eliminates the need for external cooling apparatus, reducing complexity and potential points of failure.
Real-World Impact
This patented technology aligns with Flux Marine Ltd.’s mission to advance electric boating. By enhancing power transmission efficiency and thermal management, the dual-strut design addresses common challenges in electric marine propulsion. The result is a more reliable and efficient outboard motor, potentially accelerating the adoption of electric boats in both recreational and commercial sectors.
The issuance of this patent underscores Flux Marine Ltd.’s commitment to innovation in sustainable marine technology. As the boating industry increasingly shifts toward electric solutions, such advancements are crucial for meeting performance expectations and environmental goals.
