Vehicle Door Handle Retraction to Prevent Phone Tagging Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auto flush type door handles in vehicles can collide with portable terminals during tagging, causing damage to the terminals.
Innovation Solution
A system and method that generates a message for informing the tagging status of a portable terminal and controls the door handle to retract over time after the terminal is untagged, using a server to transmit messages and alarm signals for user notification, preventing collisions by adjusting the extent of retraction based on elapsed time.

Engineering Contradiction Analysis
1Ease of operation
If the door handle is developed (protrudes) when the portable terminal is tagged to the vehicle door, then the user can access the vehicle door, but the portable terminal may collide with the door handle causing damage
Solution Approach 1:
The system performs preliminary detection to determine whether the portable terminal is in contact with the door handle before the door handle protrudes. If contact is detected, the control unit prevents the door handle from protruding, thereby avoiding collision damage to the portable terminal while still allowing normal operation when no contact is present
Solution Approach 2:
The system continuously monitors the contact status between the portable terminal and the door handle through communication signals. Based on this feedback information, the control unit dynamically adjusts the door handle's protrusion state, preventing damage when contact is detected while maintaining normal access functionality when no contact exists

AI summary
An embodiment system includes a vehicle configured to generate a message for informing a tagging status of a portable terminal, in response to the portable terminal entering the tagging status to a door handle, and to control the door handle to be developed over time after the tagging status of the portable terminal is changed to an untagging status, in response to the tagging status of the portable terminal being changed to the untagging status, and a server configured to receive the message for informing the tagging status from the vehicle and transmit the message for informing the tagging status to the portable terminal.
