Blind Spot Indicator with Deactivation Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blind spot detection systems for vehicles lack user control over activation and deactivation, and do not provide clear indication when the system is deactivated, potentially leading to missed alerts for objects in the blind spot zone.
Innovation Solution
A vehicular blind spot detection system that includes a sensor to detect objects in the blind spot zone, a first indicator to alert the driver, a controller that can be activated and deactivated by the user, and a second indicator to notify the user when the system is deactivated, ensuring the driver is aware of the status and can choose to receive visual alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blind spot detection system is always active, then the driver receives continuous safety alerts, but the system cannot be deactivated by the user when not needed
Solution Approach 1:
The system transitions from a static always-on state to a dynamic state that can be activated or deactivated by the user through an interface, allowing the system to adapt to different driving conditions and user preferences while maintaining reliability when active
2Device complexity
If the system provides no indication when deactivated, then the system remains simple, but the driver may be unaware that alerts are not functioning
Solution Approach 1:
The system implements feedback through a second indicator that communicates the deactivated state to the driver, ensuring that the driver is informed about the system status without significantly increasing overall system complexity
3Loss of information
If a second indicator is added to show system status, then the driver is informed of system status, but the device complexity increases
Solution Approach 1:
The second indicator is integrated with the first indicator or the existing display system, combining multiple functions into a unified indicator assembly that reduces overall device complexity while providing comprehensive status information

AI summary
A vehicular blind spot detection system for alerting a driver of a motor vehicle to an object in a blind spot zone of the vehicle includes a sensor configured to detect the presence of an object proximate to the vehicle in the blind spot zone. A first indicator is disposed on an outside rearview assembly and is configured to indicate that an object is in the blind spot zone of the vehicle. A controller is operably coupled with at least one of the sensor and the first indicator, wherein the controller may be activated and deactivated by a user. A second indicator is disposed proximate the first indicator and is configured to indicate that the controller has been deactivated.
