Vehicle State Notification via Ear-Mounted Alerts for Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems fail to securely and effectively notify users that their vehicle is in an undesirable state, such as unlocked or unsecured, without alerting third parties, which can lead to security issues and inefficient battery charging.
Innovation Solution
A vehicle state presentation system that includes a terminal device with an ear-mounted unit for wireless communication with the vehicle, providing notifications to the user through sound or vibration when they leave the vehicle, ensuring the user is aware of the vehicle's state without third-party awareness, and allowing remote control to adjust the vehicle's state to a secure configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notification is performed through sound from speaker or visual display in the vehicle, then the user can notice the vehicle state, but third parties can also perceive the notification compromising security
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the vehicle and the user. The vehicle sends notification signals to the mobile terminal, which then relays them to the user through the ear-mounted device. This intermediary approach allows the user to receive notifications without exposing them to third parties in the vicinity of the vehicle.
Solution Approach 2:
The notification is transferred from the spatial domain (sound/vision in the vehicle environment) to a different dimension through wireless communication. The ear-mounted device delivers notifications through bone conduction or direct ear canal transmission, creating a private communication channel that bypasses traditional air-borne sound propagation that third parties could detect.
2Loss of information
If notification is performed by call transmission or mail to mobile terminal, then the user can be notified, but the user is likely not to notice the notification
Solution Approach 1:
The ear-mounted device utilizes bone conduction technology, which transmits notifications through mechanical vibration of the skull bones directly to the inner ear. This method ensures the user notices the notification through physical sensation rather than relying on their attention to auditory or visual signals, significantly improving notification perception reliability.
Solution Approach 2:
The notification is delivered directly to the user's ear through localized bone conduction or ear canal transmission. This localized delivery method ensures the notification reaches the user's sensory system directly without being lost in general ambient notifications, making it highly reliable for capturing the user's attention.
3Object-affected harmful factors
If the vehicle enters predetermined state automatically, then security is improved, but the user loses control over the vehicle state
Solution Approach 1:
The system provides feedback to the user through notifications when the vehicle is in an insecure state. The user receives information about the current vehicle state and can then decide whether to return and change it or authorize automatic correction. This feedback loop maintains user control and awareness while enabling security improvements.
Solution Approach 2:
The vehicle is configured to automatically enter the predetermined secure state after a predetermined period following notification. This preliminary action allows the system to take security-corrective measures in advance while still giving the user opportunity to intervene if needed, balancing automatic security enforcement with user control.
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
The system effectively notifies the user of the vehicle's state, improving security and convenience by ensuring the vehicle is secured and energy-efficient, while preventing third-party awareness of the notifications, thus reducing security risks and energy consumption.
Implementation Method 1
an output unit that is provided in the ear mounting unit and performs a notification to the user through sound or vibration
Implementation Method 2
The vehicle performs wireless communication with the terminal device... a first communication unit that communicates with the terminal device through wireless communication

AI summary
A vehicle includes a notification unit that notifies an information processing device of a state of the vehicle; a reception unit that receives a first signal commanding the state to be maintained, from the information processing device; and a control unit that performs control such that maintains the state after lapse of a predetermined time as well when the reception unit receives the first signal within the predetermined time, and that performs control such that the state becomes a state different from the state after lapse of the predetermined time when the reception unit does not receive the first signal from the information processing device within the predetermined time.
