Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fishing reel is used, then the device is simple and easy to manufacture, but beginners and individuals with disabilities cannot synchronize the casting motion with line release
Solution Approach 1:
The patent replaces the traditional mechanical synchronization mechanism with an electronic control system. A microcontroller receives input from an inertial measurement unit (IMU) that detects casting motion, and controls an actuator to release the line at the optimal moment. This substitution of mechanical systems with electronic control resolves the synchronization difficulty for beginners while managing device complexity through integrated electronics.
Solution Approach 2:
The patent implements a feedback loop where the IMU continuously monitors the casting motion and provides real-time data to the microcontroller. The microcontroller processes this feedback and adjusts the actuator timing accordingly, creating a closed-loop control system that adapts to the user's casting motion and improves synchronization without requiring the user to manually coordinate release timing.
2Adaptability or versatility
If practice equipment with sensors is used, then casting technique can be taught, but the device does not combine sensors with an automatic casting mechanism in a functional reel
Solution Approach 1:
The patent creates a multi-functional device that combines the teaching capabilities of practice equipment with the functionality of a real fishing reel. The system can operate in multiple modes (manual, guided, automatic) to accommodate different skill levels, making it universally applicable to both beginners learning casting and experienced fishermen. The same sensor and actuator hardware serves both teaching and functional fishing purposes.
Solution Approach 2:
The patent implements dynamic adaptability where the reel's control mode can change based on user skill level. The system transitions from fully automatic operation for beginners to manual operation for experienced users, with the ability to adjust between guided and unguided modes. This dynamic reconfiguration allows the device to adapt its complexity and level of automation to match the user's capabilities.
3Extent of automation
If spring-loaded mechanisms are used to release line, then automatic release is achieved, but the mechanism cannot be adjusted based on user skill level
Solution Approach 1:
The patent replaces the fixed spring-loaded mechanism with a dynamic control system where the actuator's operation can be adjusted in real-time based on user skill level. The microcontroller can modify the timing, duration, and intensity of the actuator activation, allowing the system to provide full automatic release for beginners while offering partial or no automation for experienced users. This dynamic adjustment capability enables the same hardware to serve multiple skill levels.
Solution Approach 2:
The patent changes the operational parameters of the line release mechanism based on user skill level. The microcontroller can adjust parameters such as actuator activation timing, pulse width, and force applied to the release mechanism. These parameter changes allow the system to provide varying degrees of automation and control, adapting the automatic release characteristics to match the user's experience and control needs.
