Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication with sensor-independent protocols is implemented, then adaptability and ease of maintenance are improved, but device complexity increases
Solution Approach 1:
The communication system is segmented into independent functional modules: sensor components, processing components, and data communication components. Each module operates independently with standardized interfaces, allowing the system to adapt to different protocols by replacing or reconfiguring individual modules without redesigning the entire system. This modular architecture directly enables multi-protocol support while managing complexity through clear separation of concerns.
Solution Approach 2:
The data communication component is designed with universal functionality to support multiple sensor-independent protocols simultaneously. The processing component can handle various data formats and communication standards, making the system adaptable to future legal protocolling requirements without requiring hardware changes. This multi-functional design resolves the contradiction by enabling protocol adaptability through software/firmware flexibility rather than hardware complexity.
2Ease of operation
If physical cables are eliminated for data transmission, then ease of operation and maintenance are improved, but reliability of data transmission may worsen
Solution Approach 1:
The mechanical cable connection system is replaced with an electromagnetic wireless communication system. The data communication component uses electromagnetic signals to transmit measurement data between the measuring unit and processing unit, eliminating the need for physical cable connections. This substitution improves ease of maintenance by allowing the measuring unit to be easily removed and replaced without cable disconnection, while reliability is maintained through error correction protocols and redundant transmission mechanisms implemented in the wireless communication layer.
3Productivity
If processing components are integrated within measuring units, then autonomy and productivity are improved, but device complexity increases
Solution Approach 1:
The processing component is merged with the measuring unit to create an integrated autonomous measurement system. The processing component resides within the measuring unit and directly processes measurement data from sensor components without requiring external processing hardware. This merging improves productivity by enabling real-time data processing and immediate transmission of results, while the standardized interface design keeps the complexity increase manageable through functional integration rather than architectural complexity.
4Adaptability or versatility
If wireless communication is implemented between measuring and processing units, then flexibility of expansion is improved, but loss of information may increase
Solution Approach 1:
The wireless communication system incorporates feedback mechanisms where the receiving end verifies data integrity and requests retransmission if errors are detected. The data communication component uses acknowledgment protocols and error checking to ensure complete and accurate data transmission. This feedback loop compensates for potential information loss in wireless transmission, maintaining data accuracy while enabling flexible system expansion through wireless connectivity.
