Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional smart swimming goggles are used, then basic eye protection and underwater visibility are provided, but the goggles lack personalized features and comprehensive swimming information display
Solution Approach 1:
The swimming goggles integrate multiple functions including near-eye display for swimming data, wireless communication module for data transmission, multiple sensors (accelerometer, gyroscope, geomagnetic sensor, GPS, water temperature sensor, water pressure sensor, heart rate meter, oximeter) for comprehensive monitoring, and waterproof key for control, transforming a simple protective device into a multi-functional smart sports equipment that meets personalized requirements
Solution Approach 2:
The patent combines the near-eye display system, wireless communication module, processor, and multiple sensing devices into an integrated goggles structure, merging previously separate functions into a unified wearable device that provides comprehensive swimming information without requiring multiple separate equipment
2Loss of information
If conventional smart swimming goggles are used, then basic swimming functionality is provided, but comprehensive swimming information and environmental awareness are not available
Solution Approach 1:
The near-eye display system acts as an intermediary, capturing data from multiple sensors (accelerometer, gyroscope, GPS, water temperature sensor, water pressure sensor, heart rate meter, oximeter) and presenting processed swimming information and environmental data directly to the swimmer's visual field, bridging the gap between complex sensor data and user comprehension
Solution Approach 2:
The wireless communication module establishes feedback loops between the goggles and external terminal devices, allowing real-time transmission of swimming data and enabling swimmers to receive continuous information about their performance, position, and environmental conditions, thereby reducing information loss during swimming activities
3Ease of operation
If a near-eye display system is added to provide swimming data projection, then personalized information display is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical display interfaces (such as physical buttons or external screens) with a near-eye display system that projects information directly into the swimmer's field of view through optical components, eliminating the need for complex mechanical interaction mechanisms and simplifying the user interface while providing comprehensive swimming information
Solution Approach 2:
The near-eye display system transitions information presentation from external two-dimensional screens to an immersive three-dimensional visual field within the swimmer's line of sight, allowing swimming data, navigation information, and environmental parameters to be displayed in the visual field without obstructing the swimmer's view of the surrounding environment
4Measurement precision
If multiple sensors and communication modules are integrated, then comprehensive data collection is improved, but manufacturing complexity increases
Solution Approach 1:
The goggles are designed with a modular structure where the housing contains distinct functional modules including the near-eye display system, wireless communication module, processor, and sensor arrays, allowing each component to be manufactured, tested, and calibrated independently before final assembly, thereby reducing overall manufacturing complexity despite the high number of integrated components
