Glove Compartment Lock Mechanism With Shielding Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glove compartments on vehicles with exposed lid bodies face theft risks while requiring antitheft measures that do not inhibit airflow or design properties, especially with the increasing demand for securing valuables like ETC cards.
Innovation Solution
A glove compartment design featuring a lock mechanism with a fixation claw, movable claw, and shielding wall that prevents picking actions, integrated with the vehicle's cowl to maintain airflow and design integrity, and includes an operation member for easy user access while preventing unauthorized opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antitheft measures are provided for the glove compartment with an exposed lid body, then theft prevention is improved, but airflow during driving and design property are inhibited
Solution Approach 1:
The shielding wall is positioned only in the specific region where the lock mechanism is located, rather than covering the entire glove compartment exterior. This localized shielding approach prevents theft by blocking access to the lock mechanism while leaving other areas open to maintain airflow and preserve the overall design aesthetics of the vehicle exterior.
2Reliability
If a lock mechanism is provided for the glove compartment with an exposed lid body, then theft prevention is improved, but the structure becomes more complex
Solution Approach 1:
The lock mechanism is divided into distinct functional components: a fixation claw that anchors to the case body, a movable claw that engages with the fixation claw, and a shielding wall that protects the mechanism. This segmentation allows each component to perform its specific function independently, simplifying the overall design and manufacturing while providing effective theft prevention.
Solution Approach 2:
The operation member is positioned in a location that is easily accessible to the user from the exterior of the vehicle, allowing the user to operate the lock mechanism without opening the glove compartment. This extraction of the operation interface to a convenient location simplifies user interaction while maintaining security.
3Ease of operation
If the movable claw is made accessible from the outside for easy operation, then ease of operation is improved, but vulnerability to picking attacks increases
Solution Approach 1:
The shielding wall acts as an intermediary barrier between the movable claw and external tools. It allows the operation member to be accessible for legitimate user operation while blocking picking tools from reaching the movable claw, thus distinguishing between authorized and unauthorized access attempts.

AI summary
A glove compartment includes a case main body; a lid body connected to the case main body by a hinge; and a lock mechanism locking the lid body to the case main body at a closed position relative to the case main body. The lock mechanism includes a fixation claw fixed to the lid body; and a movable claw slidably attached to the case main body. When the movable claw is located in an engagement position engaged with the fixation claw, the lid body is locked to the case main body. When the movable claw slidingly moves to a release position disengaging from the fixation claw, the lid body can be opened. A shielding wall is provided, which partially shields the movable claw relative to an outside when the lid body is located at the closed position, so as to prevent a theft of housed articles.
