Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a device incorporating a sensor is attached to a user's body to measure wave data, then measurement capability is improved, but the device complexity and burden on the user increase
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the measurement device and the information processing system. Sensors mounted on the surfboard communicate wave data wirelessly to an external device, eliminating the need for complex integrated systems while maintaining measurement capability. This separates the measurement function from the processing function, reducing overall device complexity.
Solution Approach 2:
The measurement device is designed to collect multiple types of wave data (wave height, wave period, swell direction) using a single integrated sensor system. By making the measurement device multi-functional, the patent reduces the number of separate devices needed, thereby simplifying the overall system while improving measurement comprehensiveness.
2Measurement precision
If real-time wave information is provided to users, then the timing determination accuracy is improved, but the information processing complexity increases
Solution Approach 1:
The system performs preliminary processing of wave data by pre-calculating wave parameters (wave height, period, direction) at measurement points before the user needs this information. This advance processing reduces the computational burden during critical timing determination moments, improving response speed while managing processing complexity.
Solution Approach 2:
The information processing is divided into separate modules: one module collects raw sensor data, another processes wave parameters, and a third delivers timing information to the user. This segmentation allows each module to specialize in specific tasks, improving overall processing efficiency while reducing the complexity of any single component.
3Measurement precision
If multiple measurement points are used to track wave data, then the information accuracy is improved, but the system complexity and cost increase
Solution Approach 1:
The patent combines data from multiple measurement points through wireless communication into a single integrated information system. By merging the data streams from various sensors into one centralized processing system, the patent achieves comprehensive wave state information while avoiding the complexity of multiple independent measurement systems.
Data Source
AI summary
A user performing a water sport is appropriately supported. A wrist terminal includes an LCD and an output control unit. The output control unit measures a time from when a swell of a wave occurs or passes until the swell breaks. In addition, the output control unit causes the LCD to display time information of the measured time.
