Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a jet propulsion boat uses only a jet water stream generation device for propulsion, then the device complexity is low, but the ease of operation deteriorates during turns and complex maneuvers
Solution Approach 1:
The propulsion system is segmented into two independent devices: a jet water stream generation device for primary propulsion and an auxiliary propulsion device for lateral assistance. Each device handles specific propulsion functions, allowing the driver to operate with simpler controls while the system provides enhanced maneuverability through coordinated action of the segmented components
Solution Approach 2:
The control device acts as an intermediary between the steering device and the auxiliary propulsion device. It receives steering input signals and automatically activates the auxiliary propulsion device to provide lateral assistance, mediating the complex coordination between multiple propulsion systems so the driver doesn't need to manually manage each component
2Ease of operation
If the auxiliary propulsion device is activated frequently to assist turns, then the ease of operation improves, but the use of energy increases
Solution Approach 1:
The auxiliary propulsion device is activated periodically rather than continuously. The control device monitors steering operations and activates the auxiliary device only during turning maneuvers when lateral assistance is needed, then deactivates it during straight-line propulsion. This periodic activation pattern provides maneuverability assistance while minimizing energy consumption compared to continuous operation
Solution Approach 2:
The control device automatically determines when the auxiliary propulsion device should be activated based on steering input detection, eliminating the need for the driver to manually control energy usage. The system self-regulates its energy consumption by activating assistance only when mechanically necessary based on real-time operational conditions
