Vehicle Notification System for Left-Behind Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that can effectively notify users when they have left their consumer electronics devices inside a vehicle, as forgetting such devices can be inconvenient and time-consuming to retrieve.
Innovation Solution
A vehicle-based system that includes a processor and a vehicular system controllable via the processor, which receives an alert signal indicating a pre-paired consumer electronics device has been left inside, triggering the system to generate a perceptible signal outside the vehicle, such as honking the horn or flashing lights, to alert the user.

Engineering Contradiction Analysis
1Ease of operation
If a notification system is implemented to alert users when their device is left in the vehicle, then user convenience is improved, but device complexity increases
Solution Approach 1:
The system automatically detects when a device is left in the vehicle and generates notifications without requiring user intervention. The processor monitors device presence, determines if the device has been left behind, and autonomously triggers alerts through the vehicular system, allowing the system to serve itself rather than requiring manual user setup or activation.
Solution Approach 2:
The existing vehicular system components (horn, lights, display screens) are repurposed to serve multiple functions - their original functions plus the additional function of generating notification signals. This allows the notification capability to be added without requiring entirely new hardware, thereby reducing the actual increase in device complexity while improving user convenience.
2Device complexity
If existing vehicular hardware is utilized for notifications, then device complexity is minimized, but notification reliability may be affected
Solution Approach 1:
The processor acts as an intermediary that receives device presence information and translates it into appropriate notification signals through the vehicular system. This intermediary layer ensures reliable communication between the device detection logic and the notification output mechanisms, coordinating their interaction to ensure dependable notification delivery while utilizing existing hardware components.
Solution Approach 2:
The system changes the operational parameters of existing vehicular components (horn, lights, display) by controlling their activation states based on device presence detection. By dynamically adjusting when these components are activated rather than requiring new dedicated notification hardware, the system maintains reliability through proven components while minimizing added complexity.

AI summary
Computer-implemented methods, systems and apparatus are disclosed for providing notification at a vehicle that a pre-paired consumer electronics device (CED) has been left inside the vehicle. The vehicle includes a processor and a vehicular system controllable via the processor. The processor can receive an alert signal that indicates that a pre-paired CED has been left inside the vehicle during a time period after a trigger event has occurred. The processor is further configured to control activation of the vehicular system, in response to receiving the alert signal, to cause the vehicular system to generate another signal that is perceptible outside the vehicle to indicate that the pre-paired CED has been left inside the vehicle.
