Our project aims to modernize and enhance the current propeller measurement system by converting it to an advanced infrared sensor system. The marine industry is increasingly adopting 3D scanning technologies, which renders our existing system outdated and less competitive. A key challenge in this transition is the ability to measure overlapping sections of propeller blades; A task our current system can accomplish with a specialized adapter on the drop probe.

We must develop a solution that can accurately capture these complex geometries with the proposed infrared system. The carbon fiber rods used for X and Y-axis measurements are prone to breaking, each costing approximately $850 to replace and requiring significant repair time. Our project seeks to address these issues by designing a more robust, precise, and industry-aligned scanning system that reduces maintenance costs and improves overall efficiency in propeller measurements.

Several vital issues impact the feasibility and success of converting the scan arm to an infrared sensor system. First, infrared systems can be costly, particularly when purchasing from established suppliers like Keyence, which is why we are working directly with them to negotiate prices. Additionally, we are exploring data fusion with lower-end sensors, aiming to blend high-quality infrared data with more affordable sensor inputs. This approach allows us to maintain accuracy while controlling costs.

Another crucial issue is the ease of transition for current users. Since operators are accustomed to the existing system, we aim to minimize changes in the user interface and overall operation. Our approach involves mounting new sensors on the same frame, preserving the layout and workflow, while the infrared beams capture the X and Y-axis measurements. This setup ensures users can transition to the new technology without a steep learning curve.

Finally, market competitiveness is essential. With the marine industry shifting towards 3D scanning solutions, staying aligned with current trends is crucial. By adopting infrared sensor technology, we improve accuracy and durability, which enhances the system’s appeal relative to other products. Addressing these issues effectively positions our design as a cost-effective, user-friendly, and cutting-edge solution in the propeller measurement market.
