Removable Cartridge Locking Mechanism for Vehicle Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing removable cartridge locking systems in vehicles are vulnerable to theft before delivery, as the locking/unlocking button is accessible to passengers, allowing potential removal of the cartridge during transport to dealers.
Innovation Solution
A locking system that uses a movable member and trigger mechanism to prevent cartridge extraction by blocking the actuation of the trigger, ensuring the cartridge remains secured within the housing until the vehicle is sold, utilizing a combination of a rotatable plate, actuating axis, and return spring to maintain the cartridge's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking/unlocking button is made accessible to passengers for easy cartridge removal, then ease of operation is improved, but security against theft during transport deteriorates
Solution Approach 1:
The patent applies dynamics by making the triggering means movable between two positions: a first position allowing cartridge removal during normal use, and a second position blocking removal during transport. The triggering means is moved to the second position before vehicle delivery and remains there until the vehicle is sold, thus dynamically adapting the locking state to different operational phases.
Solution Approach 2:
The patent applies preliminary action by pre-positioning the triggering means in the blocked state before the vehicle is delivered to the dealer. This preliminary blocking action prevents theft during transport, and the blocking state is maintained until the vehicle is officially sold, at which point the blocking is removed to allow normal operation.
2Object-affected harmful factors
If a separate blocking system is added to prevent cartridge removal during transport, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the blocking function with the existing triggering means used for normal cartridge removal. Instead of adding a separate blocking mechanism, the same triggering means is used for both purposes: it allows removal in the first position and blocks removal in the second position. This integration avoids increasing device complexity while achieving the security goal.
Solution Approach 2:
The triggering means serves multiple functions: it enables cartridge removal during normal use (first position) and prevents cartridge removal during transport (second position). This multi-functionality eliminates the need for separate blocking and unblocking mechanisms, maintaining simplicity while achieving security during transport phases.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents unauthorized removal of the cartridge during transport and allows easy unlocking for cartridge replacement after vehicle delivery, enhancing security and user convenience.
Implementation Method 1
said system comprising a movable member, intended to close and/or open one and/or openings of said cartridge, said system further comprising a trigger, intended to authorize an extraction of said cartridge from the housing in the event of actuation

AI summary
The invention relates to a system for locking a detachable cartridge (130) in a housing (100). The system includes a movable member for closing and/or opening one and/or a plurality of openings (260a, 260b) of the cartridge (130), and a releasing mechanism (250) for allowing detachment of the cartridge (130) from the housing (100) during actuation, wherein the movable member is configured to prevent actuation of the releasing mechanism (250), i.e., prevent detachment of the cartridge (130) from the housing (100).
