Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software services are used for data exchange between adjustment device and control device, then data transmission is possible, but the control device microcontroller becomes heavily loaded
Solution Approach 1:
The patent introduces a serial interface as an intermediary communication channel between the adjustment device and control device. This interface handles data transmission independently of the microcontroller, allowing configuration data and diagnostic information to be exchanged without burdening the microcontroller's processing resources. The serial interface acts as a mediator that separates the communication function from the control function.
Solution Approach 2:
The communication functionality is segmented into a separate serial interface module that operates independently from the microcontroller. This segmentation allows the data transmission tasks to be handled by dedicated hardware circuitry rather than consuming microcontroller processing power, thus reducing the microcontroller load while maintaining full data transmission capability.
2Ease of manufacture
If extensive collaboration with manufacturer is pursued for software integration, then software services can be integrated, but development time increases
Solution Approach 1:
The adjustment device is designed to be self-sufficient by implementing a standalone serial interface that does not require manufacturer-provided software services. The device can independently access control device memory and exchange data through this hardware interface, eliminating the need for collaborative software integration work with the control device manufacturer and significantly reducing development time.
Solution Approach 2:
The patent extracts the data communication functionality from the manufacturer's software service layer and implements it as an independent hardware serial interface in the adjustment device. This extraction removes the dependency on manufacturer collaboration for software integration, allowing the adjustment device to function autonomously and reducing overall development time.
