Trunk Sound Source Identification via Camera Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in identifying the source of sounds within a vehicle's trunk as they cannot visually inspect the interior without opening it, especially during vehicle travel, and distinguishing the cause of sounds is challenging when the vehicle stops.
Innovation Solution
A vehicle status management apparatus and method that includes a sound detector, camera, and controller to photograph and display the trunk's interior when a sound is detected, analyzing images to highlight the source area and adjust lighting for better visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user gets out of the vehicle to check the trunk interior, then the user can identify the sound source, but the user convenience deteriorates and time is lost
Solution Approach 1:
The patent uses a camera to capture images of the trunk interior and transmits them to a mobile terminal, creating a visual copy of the trunk contents. This allows users to identify the sound source remotely without physically opening the trunk, resolving the contradiction between accurate sound source identification and user convenience
Solution Approach 2:
The patent introduces a communication module as an intermediary between the trunk interior and the user's mobile terminal. This intermediary transmits images and sound data, enabling remote observation and identification of the sound source without requiring the user to physically access the trunk, thus maintaining both identification accuracy and user convenience
2Loss of information
If the user opens the trunk to check the interior, then the user can see the inside, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent employs a sound detector that continuously monitors the trunk interior and automatically triggers image capture when abnormal sounds are detected. This preliminary detection and automatic activation eliminate the need for users to manually open the trunk and search for the sound source, reducing both time loss and operational complexity while ensuring visual information is obtained precisely when needed
3Measurement precision
If multiple detection devices are installed in the trunk, then the detection precision improves, but the device complexity increases
Solution Approach 1:
The patent integrates multiple detection functions into a single control unit that manages both sound detection and camera activation. This multi-functional approach allows the system to achieve improved sound detection precision through multiple sensors while avoiding increased complexity by consolidating control logic into one universal controller that coordinates all components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to identify the cause of sounds within the trunk without opening it, by displaying the interior images and highlighting the source area, facilitating easier diagnosis and reducing user inconvenience.
Implementation Method 1
a sound detector that is disposed in an object storage compartment of a vehicle and that detects a sound generated in the object storage compartment
Implementation Method 2
a camera that obtains an image by photographing an inside of the object storage compartment
