Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If alcohol detecting device is installed to detect blood alcohol content, then drunk driving detection capability is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: an alcohol detecting device with near-infrared sensor for BAC measurement, a photographing device for evidence collection, a locking device for vehicle control, and a server for data processing. Each module operates independently but communicates through wireless connections, reducing the complexity of any single component while maintaining overall system functionality.
Solution Approach 2:
A server acts as an intermediary between the alcohol detecting device, photographing device, locking device, and user mobile devices. The server receives data from sensors, processes information, and coordinates responses, thereby simplifying the architecture by centralizing complex processing logic rather than embedding it in multiple distributed units.
2Reliability
If real-time detection and locking mechanism is implemented, then prevention effectiveness is improved, but response time requirement increases system demands
Solution Approach 1:
The system performs preliminary detection of blood alcohol content before allowing vehicle operation. The alcohol detecting device continuously monitors the driver's BAC level, and the locking device is pre-positioned to immediately restrict vehicle control if excessive alcohol is detected, eliminating the need for complex real-time response algorithms during critical moments.
Solution Approach 2:
The system implements a feedback loop where the alcohol detecting device continuously monitors BAC levels, the server processes this data in real-time, and the locking device receives immediate feedback to activate or deactivate vehicle control. This closed-loop feedback system ensures rapid response while maintaining simplicity through automated decision-making algorithms.
3Measurement precision
If multiple detection methods and evidence recording are added, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system merges the alcohol detecting device with a photographing device into an integrated unit. The photographing device captures images and video evidence when excessive alcohol is detected, combining detection and evidence collection functions in a single system. This reduces overall complexity compared to having separate independent systems while maintaining high detection accuracy through the near-infrared sensor.

AI summary
A system for detecting drunken driver is presented. The system includes an alcohol detecting device, a photographing device, and a locking device. The alcohol detecting device can receive a blood alcohol content value of a driver of a vehicle detected by a sensor, and determine whether the blood alcohol content value exceeds a first predetermined value. The alcohol detecting device can send alcohol concentration exceeding information to the photographing device to record video and to the locking device to lock vehicle when the blood alcohol content value exceeds the first predetermined value.
