Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent installation device is used for emergency signaling, then the reliability of emergency signaling is improved, but the ease of installation and disassembly deteriorates
Solution Approach 1:
The emergency signaling device is divided into separate functional modules: a detection device with sensors housed in a housing, and a separate plug-in device with plug connector. This modular segmentation allows the detection device to remain permanently installed while only the plug-in device needs to be connected/disconnected, achieving both reliability and ease of installation.
Solution Approach 2:
The plug-in device acts as an intermediary component between the permanently installed detection device and the vehicle socket. It provides the electrical connection interface, allowing the detection device to be permanently mounted while enabling easy connection and disconnection through the plug-in mechanism.
2Reliability
If retrofit modules with acceleration sensors are used, then the functionality for collision detection is improved, but the device complexity increases
Solution Approach 1:
The detection device combines multiple sensor types (acceleration sensors, and optionally speed sensors, position sensors, and CO sensors) into a single integrated housing. This merging of multiple sensing functions into one device reduces overall system complexity compared to using separate retrofit modules for each sensor type.
Solution Approach 2:
The detection device is designed with multi-functionality, incorporating various sensor types that can detect different parameters (acceleration, speed, position, gas concentration). This universal detection capability allows a single device to handle multiple detection tasks, reducing the need for multiple specialized devices.
3Ease of operation
If external power supply via cigarette lighter socket is used, then the ease of installation is improved, but the reliability of power supply deteriorates
Solution Approach 1:
The detection device includes an internal energy storage device (battery) that is pre-charged before use. This preliminary energy storage ensures that the device can operate reliably even when external power supply is unavailable or unstable, maintaining functionality during critical emergency situations.
Solution Approach 2:
The energy storage device acts as a cushion against power supply failures. By storing energy in advance, the system is protected against interruptions in external power supply, ensuring continuous operation of the emergency signaling function regardless of external conditions.
