Vehicle Storage Container with Motion-Matched Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-theft systems for vehicles primarily focus on monitoring the outer shell and do not effectively protect internal objects from theft, as they do not prevent unauthorized access to items like electronic devices with NFC, Bluetooth, or WLAN capabilities within the vehicle.
Innovation Solution
A storage container for vehicles equipped with a locking mechanism that uses a motor to open and close, featuring an internal authorization element with an antenna device, control unit, and movement sensor to ensure secure access only when the correct movement characteristics are matched, along with electromagnetic shielding and an electrical energy store for autonomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic devices with radio interfaces are placed in the motor vehicle interior, then communication functionality is improved, but the risk of location by potential burglars increases
Solution Approach 1:
The electromagnetic radiation emitted by electronic devices for communication purposes is converted into a security feature. The same antenna that enables communication also detects electromagnetic signals to determine the presence and location of authorization elements, turning a potential security vulnerability into a protective mechanism.
2Reliability
If a storage container is equipped with a motor and authorization elements for secure access, then theft protection is improved, but the device complexity increases
Solution Approach 1:
The authorization element serves multiple functions: it acts as both a transmitter for electromagnetic communication and a movement sensor for security verification. The control unit integrates multiple control functions including motor control, authorization verification, and movement detection, reducing the need for separate dedicated components.
Solution Approach 2:
The control unit acts as an intermediary that coordinates between the motor, authorization element, and movement sensor. It processes authorization signals, verifies movement characteristics, and controls the motor accordingly, simplifying the overall system architecture by centralizing control logic.
3Adaptability or versatility
If the storage container operates without a stationary power source, then mobility and flexibility are improved, but the energy supply reliability may be compromised
Solution Approach 1:
The storage container is equipped with its own electrical energy store (battery) that provides autonomous power supply without requiring connection to the vehicle's electrical system. This self-contained energy supply enables the container to operate independently, maintaining security functions even when detached from the vehicle.
