Problem
Modern vehicles lack an efficient and cost-effective solution for recording and analyzing anomalous events, such as accidents, without the need for specialized hardware, as existing systems are often cumbersome and require dedicated equipment.
Innovation Solution
A phone vehicle event recorder mount that utilizes a smartphone to receive and process sensor data, disable voice calls during vehicle operation, and transmit event data to a server, leveraging standard computing functions and internet-enabled cellular phones to perform the functions of a traditional vehicle event recorder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a smartphone is used to perform vehicle event recorder functions, then device complexity and cost are reduced, but reliability may worsen due to the phone's primary design for communication rather than event recording
Solution Approach 1:
The smartphone is designed to perform multiple functions: it serves as both a communication device and a vehicle event recorder. The system integrates event recording, sensor data processing, and communication capabilities into a single universal device, eliminating the need for separate specialized hardware while reducing overall system complexity
Solution Approach 2:
The system copies the essential functionality of a dedicated event recorder into software running on the smartphone. By implementing event detection algorithms, sensor data processing, and incident recording capabilities as software applications, the system replicates specialized hardware functions using general-purpose computing resources
2Object-affected harmful factors
If voice calls are disabled during vehicle operation, then driver safety is improved, but communication functionality is reduced
Solution Approach 1:
The system automatically disables voice call functionality before the vehicle enters operation mode. By proactively preventing access to voice calls during driving conditions, the system eliminates the need for driver intervention to avoid distraction, while still allowing full communication capability when the vehicle is stationary
Solution Approach 2:
The phone's communication functionality dynamically adjusts based on vehicle operational state. Voice calls are restricted during vehicle operation but fully available when parked, allowing the system to adapt communication capabilities to current safety requirements rather than maintaining a fixed functional state
3Measurement precision
If specialized hardware is used for vehicle event recording, then measurement precision and reliability are improved, but ease of manufacture and cost are worsened
Solution Approach 1:
The system replaces physical specialized hardware with software-based event detection and processing capabilities. By using the smartphone's existing sensors, processor, and storage, combined with software algorithms for event detection, the system achieves comparable measurement precision without requiring custom-manufactured hardware components
Solution Approach 2:
The smartphone's existing sensors and processing capabilities are leveraged for event recording purposes. The system utilizes the phone's accelerometer, gyroscope, camera, and other built-in components to detect and record vehicle events, eliminating the need for separate specialized sensing hardware while maintaining adequate detection accuracy
