Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sensor and control device are integrated as a single unit, then the system is simpler to manufacture, but the volume and weight increase reducing comfort of wear
Solution Approach 1:
The system is divided into separate modules: a sensor module with sensor element and control device, and a separate evaluation/control unit. This segmentation allows each component to be optimized independently, reducing the volume of the wearable sensor portion while maintaining full functionality through wireless communication between modules.
2Duration of action of moving object
If the sensor is designed as disposable to extend wear duration, then sensor lifespan is improved, but contamination risk at the interface between disposable and reusable parts increases
Solution Approach 1:
The sensor element and its control device are extracted as a separate disposable sensor module that can be replaced independently. This eliminates the need for physical interfaces between disposable and reusable parts, removing the contamination risk at connection points while allowing extended use of the reusable evaluation unit.
Solution Approach 2:
The sensor module is designed as a disposable component with limited lifespan, intended to be replaced after a certain period. This approach extends the overall system durability by allowing frequent replacement of the consumable sensor portion while preserving the reusable evaluation and control unit for continued use.
3Volume of moving object
If more functionality is added to the sensor module to reduce volume, then device complexity increases, but this may compromise measurement precision
Solution Approach 1:
Wireless communication serves as an intermediary between the minimal sensor module and the full-featured evaluation unit. This allows the sensor module to remain simple and compact while still providing access to all system functionalities through data transmission and remote processing capabilities.
