Telescopic Wave-Forming Fin for Watercraft Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wave-generating watercrafts face issues with aesthetic appeal and collision risks due to protruding wave-generating units, and they often require additional space for retractable mechanisms, which compromises interior space utilization.
Innovation Solution
A wave-generating watercraft design featuring wave-forming fins mounted within installation spaces on the sides of the craft body, utilizing a telescopic drive aligned with the front-rear direction to extend and retract the fin between an extended and retracted position, allowing for efficient space usage and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wave-generating units are disposed outside the craft body to save interior space, then the interior space for accessories is improved, but the aesthetic quality deteriorates and collision risk increases
Solution Approach 1:
The wave-forming fin is designed to be movable between an extended position (protruding from the installation space) and a retracted position (received within the installation space). This dynamic configuration allows the fin to be extended for wave generation functionality and retracted to improve aesthetic appearance and reduce collision risk with underwater obstacles, while the telescopic drive mechanism enables smooth transition between positions.
2Ease of operation
If the telescopic drive moves in a direction transverse to the front-rear direction, then the wave-generating function is improved, but the interior space utilization deteriorates
Solution Approach 1:
The telescopic drive is reoriented to move in the front-rear direction (longitudinal dimension) rather than the transverse direction. This dimensional change allows the drive mechanism to be compactly arranged within the installation space without compromising the wave-generating function, as the fin can still be effectively extended and retracted along the longitudinal axis of the craft body.

AI summary
A wave-generating watercraft includes a craft body having an installation space receiving a wave-generating unit. A telescopic drive is mounted within the installation space and is connected to a driven unit. A wave-forming fin is connected to the driven unit and is driven by the telescopic drive to move between extended and retracted positions. The telescopic drive is aligned with a front-rear direction of the craft body and is stretchable and retractable along the front-rear direction. The wave-forming fin protrudes from the installation space when the wave-forming fin moves to the extended position and is received in the installation space when the wave-forming fin retracts.
