Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heart-rate monitors and biometric sensors use fixed operational parameters during manufacturing, then device complexity is reduced and ease of manufacture is improved, but adaptability and versatility are worsened, limiting the ability to provide sophisticated calculations and user-specific information
Solution Approach 1:
The patent implements dynamic operational parameters that can be modified after manufacturing through wireless communication. The biometric sensor system allows configuration data to be transmitted and stored, enabling the operational parameters to change dynamically based on user needs and exercise types, thus resolving the contradiction between fixed manufacturing and flexible adaptability
Solution Approach 2:
The system enables parameter changes by allowing configuration data to be wirelessly transmitted to modify operational parameters after manufacturing. This includes changing measurement parameters, processing algorithms, and display settings based on user-specific requirements, directly addressing the adaptability limitation while maintaining manufacturing simplicity
2Device complexity
If exercise-related data is processed remotely rather than locally, then device complexity is reduced, but measurement precision and reliability are worsened due to data transmission errors
Solution Approach 1:
The patent segments the processing functions between the biometric sensor (local processing of measurement data) and external devices (remote viewing and analysis). This allows critical measurement processing to occur locally with high precision while keeping the overall system complexity manageable through distributed architecture
Solution Approach 2:
The system introduces configuration data as an intermediary that enables local processing capabilities. By storing and using configuration data locally in the biometric sensor, the system achieves accurate local processing without requiring all processing power to be present, thus maintaining measurement precision while managing device complexity
3Loss of information
If advanced calculations such as energy expenditure and fitness parameters are performed, then information quality is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent applies preliminary action by pre-storing configuration data and processing algorithms in the biometric sensor before exercise sessions begin. This allows the device to perform advanced calculations during exercise using pre-loaded resources, providing high-quality information without requiring complex real-time processing or large external memory systems
Solution Approach 2:
The biometric sensor system performs self-service by independently executing advanced calculations for energy expenditure and fitness parameters using its own processing capabilities and stored configuration data. This eliminates the need for constant external processing assistance, reducing overall system complexity while maintaining information quality
