Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full meter device identification is transmitted in the data telegram, then accurate identification of the meter device is ensured, but the data telegram length increases leading to higher energy consumption and reduced battery lifetime
Solution Approach 1:
The meter device identification is segmented into two parts: a reduced part transmitted in the data telegram and additional information elements obtained from external data sources. This segmentation allows the system to transmit only essential identification data over the radio interface while retrieving complete identification information from external sources, thereby reducing transmission energy consumption while maintaining identification accuracy.
Solution Approach 2:
The system performs preliminary actions by pre-obtaining additional information elements from external data sources before or during the identification process. This allows the receiver to reconstruct the full meter device identification by combining the reduced part from the telegram with pre-fetched external information, eliminating the need to transmit the complete identification data and thus reducing energy consumption.
2Use of energy by moving object
If a reduced part of meter device identification is transmitted, then energy consumption is reduced and battery lifetime is extended, but accurate identification of the meter device becomes difficult
Solution Approach 1:
External data sources act as intermediaries that provide additional information elements needed to reconstruct the full meter device identification. These intermediaries bridge the gap between the reduced identification data transmitted in the telegram and the complete identification required for accurate meter device recognition, allowing the system to maintain identification accuracy while minimizing transmitted data.
3Reliability
If redundant information such as full identification and timing data is included in the data telegram, then communication completeness is ensured, but the ratio of actual consumption information to total data increases leading to higher energy consumption
Solution Approach 1:
The invention extracts and removes redundant information elements from the data telegram transmission. By taking out unnecessary data such as full identification and excessive timing information, the protocol reduces the total data volume transmitted while maintaining communication completeness through selective transmission of only essential information, thereby reducing energy consumption.
