Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate controllers are provided for analyzing part and data processing part, then control functions are distributed and reliable, but device complexity increases and manufacturing costs increase
Solution Approach 1:
The patent merges the data processing unit into the analyzing part by providing a communication interface within the analyzing part that communicates with the data processing unit. This integration eliminates the need for separate controllers while maintaining control reliability through standardized communication protocols.
Solution Approach 2:
The analyzing part is designed with multi-functionality by incorporating both sample analysis capabilities and communication interface capabilities. This allows the same hardware component to serve multiple purposes: analyzing samples and communicating control/data signals, thereby reducing overall device complexity.
2Ease of manufacture
If separate controllers are provided for analyzing part and data processing part, then control functions are distributed, but manufacturing costs increase
Solution Approach 1:
By combining the communication interface with the analyzing part rather than providing separate controllers, the patent reduces component count and assembly complexity, directly lowering manufacturing costs while maintaining functional separation through software/firmware control.
Solution Approach 2:
The communication interface acts as an intermediary between the analyzing part and data processing unit, enabling standardized data exchange without requiring complex point-to-point wiring or multiple dedicated controllers, thereby simplifying manufacturing.
3Reliability
If control data transmission is prioritized through interrupt transfer, then control operation stability is improved, but data processing time may be affected
Solution Approach 1:
The system uses periodic interrupt transfers at predetermined time intervals to transmit control data from the data processing unit to the analyzing part. This periodic action ensures stable control operations while allowing batch processing of data, balancing control stability with data processing efficiency.
Solution Approach 2:
The communication interface enables feedback mechanisms where the analyzing part can report status and the data processing unit can adjust control parameters in real-time through interrupt-driven communication, ensuring operational stability without continuous time-critical processing.
