Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor data before signal processing is transmitted and aggregated, then object detection accuracy is improved, but transmission capacity requirement increases
Solution Approach 1:
The patent extracts only the necessary detection results from sensor data before transmission, rather than transmitting all raw sensor data. This extraction process removes unnecessary information while retaining the essential detection results needed for accurate object detection, thereby reducing transmission capacity requirements while maintaining detection accuracy.
Solution Approach 2:
The patent introduces an intermediary processing step that performs signal processing and extraction locally at the sensor end before transmission. This intermediary function transforms raw sensor data into condensed detection results, serving as a bridge between high-accuracy detection requirements and reduced transmission capacity needs.
2Productivity
If high-capacity communication lines are used for each sensor, then data transmission capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts only essential detection results from sensor data, significantly reducing the data volume that needs to be transmitted. This extraction eliminates the need for high-capacity communication lines for each sensor, thereby reducing system complexity and cost while maintaining adequate data transmission capability.
Solution Approach 2:
The patent changes the data parameter from raw sensor data to processed detection results, fundamentally altering the data characteristics. This parameter change reduces the data volume and transmission requirements, allowing the use of simpler, lower-cost communication infrastructure while maintaining system productivity.
