Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If entire EtherCAT frames are processed and transmitted to multiple devices, then all devices receive complete data, but latency increases and resources are wasted
Solution Approach 1:
The patent segments the EtherCAT frame into individual datagrams, each associated with a specific device. Instead of processing and transmitting the entire frame to all devices, the system divides the data into discrete units (datagrams) that can be selectively extracted and transmitted only to the intended recipient devices, thereby reducing latency and resource consumption while maintaining data completeness for each device.
Solution Approach 2:
The patent extracts only the relevant datagrams from the EtherCAT frame for each specific device. Rather than transmitting the complete frame to all devices, the system identifies and extracts only the necessary datagrams for each device based on device identifiers, eliminating unnecessary data transmission and processing overhead while ensuring each device receives its required data.
2Reliability
If entire EtherCAT frames are transmitted to multiple devices, then all devices receive data, but resource usage increases due to unnecessary data transmission
Solution Approach 1:
The patent segments the EtherCAT frame into device-specific datagrams, enabling selective transmission. Each datagram is associated with a specific device identifier, allowing the system to transmit only the necessary data units to each device rather than broadcasting the entire frame, thus reducing transmission resources and energy consumption while ensuring reliable data delivery.
Solution Approach 2:
The patent applies local quality by making the data transmission tailored to each device's specific needs. Each datagram is customized for its target device based on device identifiers, ensuring that each device receives only the data relevant to it. This targeted approach reduces unnecessary resource usage while maintaining reliable data delivery for each specific device.
3Adaptability or versatility
If EtherCAT frames are processed in traditional wireless systems, then compatibility is maintained, but processing efficiency decreases
Solution Approach 1:
The patent segments the EtherCAT frame into individual datagrams that can be processed independently. This segmentation enables more efficient processing by allowing parallel extraction and transmission of datagrams to multiple devices simultaneously, while still maintaining compatibility with the EtherCAT protocol structure and device expectations.
Solution Approach 2:
The patent introduces dynamic processing by extracting and transmitting datagrams based on real-time device identifiers and data relevance. The system dynamically determines which datagrams to extract and transmit to which devices, rather than following a static broadcast approach, thereby improving processing efficiency while maintaining protocol compatibility through adaptive data selection.
