Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sonar equipment is used for underwater environment detection, then detection capability is achieved, but device size becomes large and portability deteriorates
Solution Approach 1:
The patent replaces conventional mechanical sonar systems with an electronic detection system comprising a control apparatus and detection apparatus. The detection apparatus uses electronic sensors and signal processing to detect underwater environments, eliminating the need for bulky mechanical sonar components while maintaining detection capability.
Solution Approach 2:
The control apparatus and detection apparatus are designed as integrated multi-functional units that can perform various underwater detection tasks (terrain mapping, depth measurement, temperature detection) using a single compact device, rather than requiring separate specialized equipment for each function.
2Measurement precision
If conventional sonar equipment is used for underwater environment detection, then detection function is provided, but cost increases
Solution Approach 1:
The patent employs cost-effective electronic sensors and processing components in the detection apparatus that are less expensive than conventional sonar systems. The design uses affordable microcontrollers, standard sensors, and simple signal processing algorithms to achieve detection functionality at lower cost.
Solution Approach 2:
The system uses electronic signal processing to create digital representations of underwater environments rather than requiring complex physical sonar hardware. Software-based detection algorithms process sensor data to generate virtual models of the underwater terrain and conditions.
3Measurement precision
If conventional sonar equipment is used for underwater environment detection, then detection capability is achieved, but power consumption increases
Solution Approach 1:
The detection apparatus performs detections at periodic intervals rather than continuously, reducing power consumption. The system activates the detection apparatus only when needed (e.g., when the fishing rod is cast into water or when environmental changes are detected) and uses low-power sleep modes between active detection periods.
Solution Approach 2:
The control apparatus automatically manages power distribution to the detection apparatus based on operational needs, activating detection functions only when environmental conditions or device state indicate detection is required, thereby eliminating continuous power consumption.
4Measurement precision
If conventional sonar equipment is used for underwater environment detection, then detection function is provided, but operation complexity increases
Solution Approach 1:
The control apparatus automatically controls the detection apparatus based on the operational state of the fishing rod and environmental conditions. The system self-activates detection functions when the rod is cast into water and automatically processes results, eliminating the need for manual operation controls and simplifying user interaction.
Solution Approach 2:
The system provides automatic feedback loops where the control apparatus monitors detection results and adjusts detection parameters or frequency based on environmental conditions, eliminating the need for manual adjustment by the operator and simplifying operation.
