Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex steering device structure is used, then steering functionality is achieved, but device complexity increases and operation becomes inconvenient
Solution Approach 1:
The steering device is divided into separate functional components: a rudder for directional control, a propeller for propulsion, and a mounting mechanism for attachment. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining steering effectiveness.
Solution Approach 2:
The patent combines the rudder and propeller into a unified steering device assembly that is mounted together on the boat body. This merging of functions into a single integrated unit reduces the number of separate components needed, thereby reducing device complexity while achieving both steering and propulsion capabilities.
2Loss of energy
If existing steering device structure is used, then steering function is provided, but water resistance increases causing power loss
Solution Approach 1:
The patent optimizes the geometric parameters of the rudder and propeller, including their shapes, sizes, and angles, to reduce water resistance. By carefully designing the profile and dimensions of these components, the device achieves efficient water flow characteristics that minimize energy loss while maintaining effective steering function.
3Ease of operation
If complex steering device is used, then steering capability is achieved, but operation becomes inconvenient and power is lost
Solution Approach 1:
The steering device is designed to be self-contained and easy to operate without requiring complex control systems. The rudder and propeller are mounted in a configuration that allows direct manual operation, where the operator can easily control the steering direction and propulsion power without needing additional mechanical or electronic assistance, thereby simplifying operation and reducing energy consumption.
