Vehicle Trunk Lid Automatic Closing via Statistical Item Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automatically closing a vehicle trunk lid lack flexibility and smartness, often requiring manual intervention, especially when the user is unloading cargo with both hands.
Innovation Solution
A system comprising a trunk sensor system, a trunk lid actuator, and a control unit that statistically determines frequently remaining items in the trunk after travel, allowing for automatic closure when the current items match those frequently left behind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual closing of the trunk lid is required, then the system structure remains simple, but the ease of operation deteriorates when the user is unloading cargo with both hands
Solution Approach 1:
The trunk lid closing system operates autonomously by detecting remaining items in the trunk and automatically initiating closure when criteria are met, eliminating the need for manual operation and allowing users to unload cargo with both hands without needing to close the trunk lid manually
Solution Approach 2:
The manual mechanical closing action is replaced by an automated system using sensors (optical, acoustic, or weight-based) and a control unit with actuator to detect item conditions and execute closing, substituting mechanical manual operation with sensor-based automated control
2Adaptability or versatility
If the trunk lid closes automatically based on simple presence sensors, then the ease of operation improves, but the adaptability and smartness of the system deteriorates
Solution Approach 1:
The control unit performs preliminary statistical analysis of item removal patterns from historical data before making the closing decision, pre-determining which items are typically removed and which remain, enabling more intelligent and adaptable closing decisions
Solution Approach 2:
The system continuously monitors the trunk interior using multiple sensor types (optical sensors, acoustic sensors, weight sensors) to detect item presence and removal, using this feedback to dynamically update statistical models and adjust closing timing for improved adaptability
3Productivity
If the trunk lid remains open until manually closed, then the reliability of cargo security is maintained, but the loss of time increases when users need to unload cargo
Solution Approach 1:
The trunk lid closing operation is performed continuously and automatically based on detected item conditions, eliminating interruptions caused by manual operation requirements and allowing the user to continuously unload cargo without needing to pause to close the trunk lid

AI summary
A system for automatically closing a trunk lid of a vehicle. The system comprises a trunk sensor system configured for detecting items in a luggage trunk, a trunk lid actuator for automatic closing of the trunk lid, and a control unit connected to the trunk sensor system and to the trunk lid actuator. The control unit is arranged for statistically determining, based on a set of observations of a trunk interior space by means of the trunk sensor system in connection with termination of a set of vehicle travels, one or more items or combination of items that are frequently remaining in the luggage trunk after completed travel, while preferably taking into account the one or more items stored in the luggage trunk during the travel, detecting opening of the trunk lid, detecting current items in the luggage trunk by means of the trunk sensor system, and controlling the trunk lid actuator for automatic closing of the trunk lid when the current items correspond to said one or more items or combination of items that are frequently remaining in the luggage trunk after a journey. The disclosure also relates to a corresponding computer-implemented method for automatically closing a trunk lid of a vehicle luggage trunk.
