Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a propulsion device is added to an aquatic vessel, then propulsion capability is improved, but the device becomes more complex and heavier
Solution Approach 1:
The propulsion system is divided into separate modular components: a propulsion unit with motor and propeller, a control unit with processor, and a power unit with battery. These modules can be independently attached to or removed from the aquatic vessel, allowing propulsion capability to be added without permanently complicating the vessel structure.
Solution Approach 2:
The control unit serves multiple functions: it controls the motor speed and direction, monitors system status through sensors, and can operate in different modes (manual control, automatic following mode). This multi-functionality reduces the need for separate dedicated components for each function.
