Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional stethoscope design is used, then device simplicity is maintained, but diagnostic capability and data transmission functionality are limited
Solution Approach 1:
The stethoscope is divided into functionally independent modules: sensor module for acoustic signal acquisition, processor module for digital signal processing, wireless communication module for data transmission, power module for energy supply, and control module for user interaction. Each module performs a specific function, allowing the system to achieve enhanced diagnostic capabilities while maintaining manageable complexity through modular architecture.
2Loss of information
If wireless communication module is added, then data transmission capability is improved, but device complexity increases
Solution Approach 1:
The processor module serves multiple functions: it processes acoustic signals from the sensor module, prepares data for wireless transmission, and manages power distribution. The wireless communication module not only transmits data but also receives commands and configuration data. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving improved data transmission capability.
3Measurement precision
If digital signal processing is implemented, then diagnostic accuracy is enhanced, but device complexity and power consumption increase
Solution Approach 1:
The processor module implements digital signal processing with adjustable processing levels. It can perform basic filtering and analysis for routine examinations, or engage in more intensive processing when diagnostic accuracy requirements are higher. The power module provides variable power output to match processing demands, allowing the system to consume only the necessary amount of power for each diagnostic task rather than operating at maximum capacity continuously.
4Adaptability or versatility
If multiple modules are integrated, then functionality is improved, but ease of operation becomes more difficult
Solution Approach 1:
The control module integrates multiple control functions into a unified interface: it manages sensor activation, processor operations, wireless communication settings, and power distribution through a single set of controls. This consolidation allows the user to operate the complex multi-module system through a simplified interface, improving ease of operation while maintaining enhanced functionality across all modules.
