Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new sensors are added to home appliances, then sensing functions and new features are improved, but device complexity and assembly requirements increase
Solution Approach 1:
The sensor device is designed with a universal connector that can accommodate multiple types of sensor modules (first sensor module and second sensor module). The processor automatically identifies the connected sensor type and configures appropriate communication settings, allowing one device structure to serve multiple sensing functions without requiring different hardware assemblies for each sensor type.
Solution Approach 2:
The communication settings are made dynamic and adaptable rather than fixed. The processor automatically adjusts communication parameters (such as communication method selection) based on the identified sensor module type and environmental conditions, enabling the system to optimize performance for different sensor configurations without requiring manual reconfiguration or disassembly.
2Device complexity
If communication settings are fixed, then device simplicity is maintained, but communication disconnection occurs in varying product use environments
Solution Approach 1:
The communication settings are made dynamic and adaptable rather than fixed. The processor automatically adjusts communication parameters (such as communication method selection) based on the identified sensor module type and environmental conditions, enabling the system to optimize performance for different sensor configurations without requiring manual reconfiguration or disassembly.
Solution Approach 2:
The system implements feedback mechanisms where the processor monitors communication status and automatically switches communication methods when disconnection is detected. The processor identifies the sensor module type, selects appropriate communication settings based on this identification, and can dynamically adjust settings in response to communication status, ensuring reliable connection across varying environments.
3Manufacturing precision
If manual sensor replacement is required, then manufacturing precision is maintained, but productivity and ease of operation decrease
Solution Approach 1:
The sensor system is segmented into modular sensor modules that can be independently connected and disconnected through the universal connector. This segmentation allows individual sensor modules to be replaced or updated without affecting the main device structure or requiring disassembly of other components, significantly improving update efficiency while maintaining connection precision.
Solution Approach 2:
The processor is pre-programmed with identification capabilities and communication setting templates for different sensor module types. When a sensor module is connected, the processor automatically identifies it and retrieves the appropriate communication settings, eliminating the need for manual configuration and enabling rapid sensor replacement and setup.
4Ease of operation
If automatic sensor identification is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The processor is pre-programmed with identification capabilities and communication setting templates for different sensor module types. When a sensor module is connected, the processor automatically identifies it and retrieves the appropriate communication settings, eliminating the need for manual configuration and enabling rapid sensor replacement and setup.
