Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If driver assistance systems use basic driving information only, then the system complexity is low, but the health state evaluation accuracy is insufficient
Solution Approach 1:
The patent combines multiple information sources including biological information from wearable devices, driving information from vehicle sensors, and environmental information from external sources into a unified evaluation system. This integration enables comprehensive health state assessment by merging data from diverse sources to improve evaluation accuracy while managing system complexity through coordinated processing.
Solution Approach 2:
The evaluation system is designed to handle multiple types of data (biological, driving, environmental) and perform various evaluation functions (health state assessment, driving ability evaluation, safety determination). This multi-functional approach allows the system to process diverse information streams through a unified framework, improving measurement precision without requiring separate specialized systems for each function.
2Reliability
If the system collects comprehensive biological information from multiple sources, then the evaluation reliability improves, but the information processing time increases
Solution Approach 1:
The system performs preliminary processing of biological information by acquiring and pre-processing data from wearable devices before actual evaluation occurs. Biological information is collected and prepared in advance, allowing the evaluation process to use pre-processed data rather than raw data, thereby reducing real-time processing time while maintaining comprehensive data collection for reliable evaluation.
Solution Approach 2:
The system continuously acquires biological information from wearable devices and maintains ongoing data collection processes. This continuous operation allows the system to accumulate data over time and perform evaluations based on sustained information streams, improving reliability through continuous monitoring while managing processing time through ongoing rather than intermittent operations.
Data Source
AI summary
A smartphone includes: an acquisition unit configured to acquire first biological information from a smartwatch that is worn by a user and detects biological information about the user, and acquire second biological information from an information holding institution that holds biological information about the user; and an evaluation unit configured to evaluate whether a health state of the user is an appropriate state as a driver of a vehicle, based on the first biological information and the second biological information.
