Vehicle Door Unlocking With Proximity Standby Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door unlocking systems face challenges in balancing convenience and safety, particularly for users who need to operate communication terminals with one hand, risking disruption in balance and potential theft if doors are unlocked remotely.
Innovation Solution
A vehicle door unlocking system that shifts to a standby mode upon receiving an unlocking command from a distance, automatically unlocking the door when the user's position is recognized within a predefined area using wireless communication and facial recognition, allowing hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is unlocked remotely by operating communication terminals manually beforehand, then the convenience of unlocking is improved, but the safety is reduced because there is a possibility that the doors may be opened by another person before the user moves to the vicinity of the vehicle
Solution Approach 1:
The system performs preliminary action by having the user send an unlocking command in advance from a distance, but the actual door unlocking is delayed until the user approaches the vehicle. This resolves the contradiction by allowing convenience preparation while ensuring safety through proximity verification before final execution.
Solution Approach 2:
The system uses feedback by detecting the user's proximity through sensors (e.g., camera, proximity sensor) and only unlocking the door when the user is within a predetermined distance. This feedback mechanism ensures that remote commands are only executed when safety conditions are met, balancing convenience with security.
2Ease of operation
If a sensor is mounted underneath a door and the user unlocks the door by contacting the door with his/her foot, then the convenience of unlocking is improved, but the user's balance may be disrupted and there is a risk of falling
Solution Approach 1:
The patent replaces the mechanical foot-kicking system with a wireless communication terminal system that uses electromagnetic signals for authentication and proximity detection. This substitution eliminates the need for physical contact with the vehicle, thereby avoiding balance disruption and falling risks while maintaining unlocking convenience.
3Reliability
If the user is required to operate communication terminals manually to unlock the vehicle door, then the safety of unlocking is improved, but the convenience is reduced when the user is holding an object in his or her hand
Solution Approach 1:
The system implements self-service by automatically detecting the user's proximity and executing the door unlocking without requiring manual terminal operation at the moment of unlocking. The user only needs to have sent the preliminary unlocking command, and the system handles the rest automatically when the user approaches, eliminating the need for hand operations while maintaining security.
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
Enhances safety by preventing unauthorized access and maintains convenience by enabling remote unlocking and hands-free operation, balancing user safety and ease of use.
Implementation Method 1
a communication terminal capable of communicating wirelessly with a vehicle
Implementation Method 2
the recognition portion recognizes whether the user enters the position within the second distance from the vehicle according to facial recognition information of the user acquired by an external camera mounted on the vehicle
Data Source
AI summary
A vehicle door unlocking system considering convenience and safety of door unlocking is disclosed. The vehicle door unlocking system utilizes a communication terminal capable of communicating wirelessly with a vehicle to unlock a vehicle door, and includes: a receiving portion receiving an unlocking command issued by an operation of a user; and a recognition portion recognizing a position of the user relative to the vehicle. When the receiving portion receives an unlocking command issued from a position more than a first distance away from the vehicle by a first operation of the user, or when the receiving portion receives an unlocking command issued by a second operation of the user, a standby mode is shifted to. When the recognition portion in the standby mode recognizes that the user enters a position within a second distance that is less than the first distance from the vehicle, the vehicle door is unlocked.
