Vehicle Trunk Lid Automatic Opening System with Foot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle trunk lid opening systems are inconvenient for users, particularly elderly, pregnant, or disabled individuals, as they require lifting a foot to unlock and may cause unnecessary waiting for the trunk to open.
Innovation Solution
An opening and closing system that includes a lock device, a striker device, a first human detection sensor, and a control device to automatically unlock and pop up the trunk lid upon detection of the user, with illumination to guide the user, reducing the need for manual operation and enhancing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the unlocking switch is placed on a downwardly facing surface of the trunk lid to maintain aesthetic appearance, then the external appearance is improved, but the ease of operation deteriorates as users must search for or bend to locate the switch
Solution Approach 1:
The system uses automatic detection of the user's presence and intent (through sensor detection of foot placement or hand approach) to trigger the unlocking and opening sequence without requiring the user to manually operate the switch, thereby eliminating the need for users to search for or bend to locate the switch while maintaining aesthetic appearance
2Ease of operation
If the trunk lid is unlocked and pops up automatically after the user places their foot underneath the vehicle body, then the ease of operation is improved, but the loss of time increases as the user must wait in front of the trunk lid from unlocking until it pops up
Solution Approach 1:
The system performs preliminary actions by detecting the user's intent in advance (through sensor detection of foot placement or hand approach) and automatically initiating the unlocking and opening sequence without requiring the user to wait, thereby reducing the waiting time while maintaining ease of operation

AI summary
An opening and closing system includes a first human detection sensor configured to detect a vehicle user who enters a first area defined on a periphery of a vehicle body, a lamp visible by the vehicle user who enters the first area, and a control device configured to control an unlocking operation of the lock device, a closing operation of the striker device, a pop-up operation of the striker device, and switching on and off of the lamp. The control device switches on the lamp when the vehicle user is detected by the first human detection sensor and starts the controlling of the unlocking operation of the lock device and the closing operation and the pop-up operation of the striker device in response to the lamp being switched on.
