Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are integrated and mounted on a vehicle, then the sensing capability is improved, but the wiring design becomes complex due to the large number of wires between sensors and the control device
Solution Approach 1:
The patent combines multiple sensor data transmission lines into a single communication bus, allowing multiple detectors to transmit their data through shared communication paths rather than requiring separate wires for each sensor, thereby reducing wiring complexity while maintaining comprehensive sensing capability
Solution Approach 2:
The control device is designed to handle multiple types of sensor data through a universal communication interface, enabling a single communication bus to carry data from various detectors (camera, microphone, sensor arrays) without requiring dedicated wiring for each sensor type
2Ease of operation
If data from multiple detectors are directly transmitted to the control device, then the data transmission is straightforward, but the data is not effectively utilized due to lack of integration
Solution Approach 1:
The system performs preliminary integration and processing of data from multiple detectors before transmitting to the control device, combining relevant information in advance so that the control device receives pre-processed, integrated data that is ready for immediate utilization without requiring extensive additional processing
Solution Approach 2:
The patent introduces an intermediary data processing layer that receives data from multiple detectors, integrates and correlates the information, and then transmits the processed integrated data to the control device, ensuring that the data is effectively utilized by presenting it in a coordinated and meaningful format
