Vehicle Driver Observation System with Multi-Function Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ability of drivers in smaller vehicles to see traffic conditions around their vehicle is diminished, particularly in directions other than straight ahead, due to the increasing number of larger vehicles on the road, necessitating an enhancement of the driver's line of vision and security against theft and vandalism.
Innovation Solution
A driver observation and security system with sensors and camera modules mounted on and inside the vehicle, providing real-time video feeds of the exterior and interior to the driver, along with a control mechanism for operation and recording, and a transmitter for remote viewing, enhancing visibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If camera modules and sensors are added to extend driver vision and provide security monitoring, then the driver's line of vision and security capability are improved, but the device complexity increases
Solution Approach 1:
The camera modules serve multiple functions: they extend the driver's vision to blind spots during normal operation and simultaneously act as security monitoring devices when unauthorized entry is detected. This multi-functionality reduces the need for separate dedicated security cameras, thereby limiting the increase in device complexity while achieving both vision extension and security monitoring goals.
Solution Approach 2:
The system uses the same camera infrastructure for both driver assistance and security purposes. When sensors detect unauthorized entry, the existing camera modules automatically begin recording and transmitting security-relevant images without requiring additional dedicated security imaging devices, allowing the system to serve itself across multiple functional domains.
2Reliability
If multiple camera modules and sensors are installed on the vehicle, then security monitoring capability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The system divides the monitoring function into separate modular components: exterior cameras for vision extension, interior cameras for security monitoring, and sensors for detection. Each module is independently manufactured and then integrated through standardized connections, making the overall system more manageable during vehicle assembly despite the multiple components involved.
Solution Approach 2:
The camera modules and sensors are designed as pre-assembled units that can be installed at specific vehicle locations during manufacturing. The control mechanism is pre-programmed with detection algorithms and response protocols, allowing workers to simply connect pre-tested modules rather than assembling and debugging individual components during vehicle assembly.
3Reliability
If real-time video transmission is implemented for remote viewing, then security response capability is improved, but the use of energy increases
Solution Approach 1:
Instead of continuous real-time transmission, the system transmits video data periodically or event-triggered when motion is detected or unauthorized entry is confirmed. This approach maintains security response capability by providing timely video evidence while dramatically reducing power consumption compared to continuous transmission.
Solution Approach 2:
The system uses lower-resolution or compressed video transmission suitable for security monitoring purposes rather than high-definition continuous streaming. The transmitted video data serves its purpose as evidence or alert information without requiring sustained high-bandwidth transmission, reducing energy usage while maintaining adequate security response capability.
