Solution Overview
Problem
Adjusting the tilt angle of a ship propulsion machine body with respect to the hull to a desired angle is difficult, especially for beginners, leading to inefficiencies and inaccuracies, particularly during high-speed travel.
Innovation Solution
A tilt-angle adjusting apparatus that includes a motor and a motor control unit, which detects the hull angle using a sensor and adjusts the tilt angle based on this information, allowing for precise control to maintain a suitable traveling posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation with operation switch is used to adjust tilt angle, then the structure is simple, but the adjustment accuracy and ease of operation deteriorate
Solution Approach 1:
The patent implements automatic feedback control by detecting the hull angle with a sensor and comparing it to a target angle, then automatically adjusting the tilt angle through motor control. This eliminates the need for manual operation while achieving high precision, resolving the contradiction between ease of operation and device complexity by automating the feedback loop.
Solution Approach 2:
The system performs self-adjustment by automatically detecting its own state (hull angle) and correcting deviations from the target angle without external intervention. The motor control unit autonomously determines when to extend or retract the hydraulic cylinder based on the detected angle, making the system self-regulating and eliminating manual operation requirements.
2Manufacturing precision
If manual operation is used to adjust tilt angle, then the device structure is simple, but the adjustment precision deteriorates
Solution Approach 1:
The patent employs continuous feedback control where the hull angle sensor constantly monitors the actual angle and compares it to the target angle. The motor control unit processes this feedback information and automatically adjusts the hydraulic cylinder position, achieving high precision tilt angle control that would be difficult to achieve manually while managing system complexity through integrated control logic.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated electromechanical control system. The motor control unit substitutes for manual judgment and adjustment actions, using electronic sensors and control algorithms to achieve superior precision compared to manual operation, while the overall system complexity is managed through efficient control architecture.
