Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device uses its own sensor information independently, then the device can operate autonomously, but the information utilization efficiency is low and functionality is limited
Solution Approach 1:
The patent combines the mobile device's sensor information with the vehicle's sensor information through a communication interface. The input switching unit merges these two information sources by selecting which one to feed to the process execution unit, thereby enhancing functionality and information utilization efficiency without compromising autonomous operation.
Solution Approach 2:
The mobile device is designed to perform its normal functions autonomously while also having the capability to utilize vehicle sensor information when available. This multi-functionality allows the device to adapt between independent operation and collaborative operation with the vehicle system, improving overall versatility.
2Productivity
If the mobile device switches between using its own sensor information and vehicle sensor information, then information utilization efficiency improves, but the system complexity increases
Solution Approach 1:
The input switching unit acts as an intermediary component that manages the complexity of selecting between mobile device sensor information and vehicle sensor information. This dedicated switching component simplifies the overall system architecture by centralizing the decision-making logic for information source selection, rather than requiring complex integration throughout the entire system.
3Measurement precision
If the mobile device continuously monitors both its own sensors and vehicle sensors, then the accuracy of information derivation improves, but the energy consumption increases
Solution Approach 1:
The system establishes a communication interface that can periodically or on-demand retrieve vehicle sensor information rather than requiring continuous monitoring. The input switching unit can select between information sources based on availability and accuracy needs, allowing the mobile device to maintain measurement precision while reducing energy consumption by not continuously monitoring both sensor systems simultaneously.
Data Source
AI summary
In the mobile device, the processing execution unit performs processing using sensor information detected by the sensor. Also, in the vehicle, a signal including sensor information detected by a sensor is transmitted from a transmission device. In the information control device, the reception device of the acquisition unit receives the signal transmitted from the transmission device. When the reception device is stably receiving the signal, the signal stability determination unit inputs sensor information included in the received signal the process execution unit instead of the sensor information from the sensor. As a result, the sensor information detected by the vehicle sensors can be effectively used in the mobile device.
