Vehicle Position Notification Cover Battery Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle position information notification apparatuses can be stolen without triggering an emergency notification when both power supplies are connected, as the SIM card can be removed without disconnecting the internal battery power supply, preventing communication and tracking.
Innovation Solution
The apparatus is designed such that the SIM card can only be removed after the internal battery power supply is disconnected, ensuring that position information is transmitted via wireless communication upon disconnection of either power supply, thereby preventing theft from going undetected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the SIM card can be removed while both power supplies are connected, then the apparatus structure allows easy access to SIM card, but the emergency notification function fails when theft occurs
Solution Approach 1:
The patent applies preliminary anti-action by designing the cover structure to automatically disconnect the internal battery power supply before the SIM card can be removed. The cover integration with the internal battery power supply creates a mechanical interlock where removing the cover (which would allow SIM card access) first disconnects the power supply connection, preventing the harmful scenario where SIM card is removed while power is still connected.
2Reliability
If the cover and internal battery power supply are integrated, then the SIM card removal is prevented during operation, but the device complexity increases
Solution Approach 1:
The patent applies merging by integrating the cover with the internal battery power supply into a single unified component. This combination eliminates the need for separate cover and power supply assemblies, reducing the number of parts and connection points while achieving the security function of preventing SIM card removal during operation.
Solution Approach 2:
The integrated cover serves multiple functions: it protects the internal components, maintains the structural integrity of the housing, and simultaneously acts as the internal battery power supply. This multi-functionality reduces overall device complexity while achieving the security objective.

AI summary
When electrical connection of either a vehicle power supply or an internal battery power supply is disconnected, a vehicle position information notification apparatus issues a notification about measured position information via a wireless communication. The vehicle position information notification apparatus includes a case (20) having an opening portion (23), a cover (22) covering the opening portion of the case, and a circuit board (21) disposed in the case, and an internal battery power supply part (31) constituting the internal battery power supply. The circuit board includes a vehicle power supply connector (28), a communication circuit (9), and a SIM card connector (29) electrically connectable with a SIM card (10). The cover and the internal battery power supply are integrated with each other. When the cover is operated to open the case, the internal battery power supply is disconnected, and then the SIM card can be removed. Therefore, in the event of theft of a vehicle or the vehicle position information notification apparatus, failure to issue the notification of the position information can be avoided.
