Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is built directly into a rudder or fin, then the surfboard can be motorized, but the device lacks modularity and cannot be adapted for diving or swimming applications
Solution Approach 1:
The motorized system is divided into separate modular components: a motor unit that can be detached from the surfboard, allowing the same motor unit to be used for surfing, diving, or swimming applications. This segmentation enables the system to be reconfigured for different activities without requiring structural modifications to the board.
Solution Approach 2:
The motor unit is designed as a universal component that can be attached to various types of boards (surfboards, dive boards, swim boards) and configured for multiple functions (surfing, diving, swimming). The standardized mounting interface and detachable design allow the same motor unit to serve multiple purposes across different water sports activities.
2Adaptability or versatility
If a motorized system is integrated into the surfboard structure, then propulsion is achieved, but the device cannot easily attach various types of fins and surfboards
Solution Approach 1:
The system employs dynamic, reconfigurable mounting interfaces that allow the motor unit to be easily attached and detached from different surfboard configurations. The adjustable fin attachment mechanism enables the system to adapt to various fin types and board shapes without requiring permanent structural modifications, providing flexibility for different surfing styles and board preferences.
3Productivity
If the propeller is exposed, then propulsion efficiency is maximized, but safety hazards increase for surfers and swimmers
Solution Approach 1:
The propeller is nested within a protective cowling that encloses the rotating blades while allowing water flow for propulsion. The cowling acts as a protective shell that contains the hazardous moving parts, preventing direct contact with surfers and swimmers while maintaining the propeller's ability to generate thrust through the enclosed structure.
