Spring-Loaded Plunger Lock for Vehicle Accessory Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle accessories installed in open areas, such as pickup truck beds, are prone to unauthorized removal, and existing security measures are either ineffective or aesthetically unappealing, often requiring specialized tools or keys that can be lost or misplaced.
Innovation Solution
A vehicle accessory lock system that uses a spring-loaded plunger housing mountable through a door jamb, which engages a plunger receiver upon closure of a hinged door, securing the accessory without overt security measures, and is integrated with the tailgate lock mechanism for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lock-and-key devices are used to secure vehicle accessories, then security against unauthorized removal is improved, but vehicle aesthetics deteriorate due to overt security measures
Solution Approach 1:
The locking mechanism is extracted from visible exterior locations and placed inside the vehicle panel cavity. The plunger housing is mounted within the panel space, and the security plunger engages with the accessory through a receiver that is hidden from external view, thereby maintaining aesthetics while providing security.
Solution Approach 2:
The locking mechanism is nested within the vehicle panel structure. The plunger housing is received within the panel space, and the security plunger is received within the plunger housing, creating a nested arrangement that conceals the security device within the vehicle's existing structure.
2Reliability
If specialized tools or keys are required to remove accessories, then security is improved, but ease of operation deteriorates due to risk of losing keys or tools
Solution Approach 1:
The system uses the vehicle's existing door locking mechanism to operate the accessory lock. When the door is locked, the plunger is engaged, securing the accessory. When the door is unlocked, the plunger retracts, releasing the accessory. This self-service approach eliminates the need for separate keys or tools.
Solution Approach 2:
The door locking mechanism serves dual functions: securing the door and simultaneously securing the accessory. The single action of locking/unlocking the door controls both the door access and the accessory retention, simplifying the user interface.
3Reliability
If complex locking techniques are used, then security is improved, but device complexity increases making the system more appealing to thieves
Solution Approach 1:
The accessory locking function is merged with the existing door locking mechanism. The plunger housing integrates with the door jamb structure, and the security plunger works in conjunction with the door lock, combining multiple security functions into a single integrated system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively secures vehicle accessories by concealing the locking mechanism and requiring authorized access to unlock the tailgate, thereby preventing unauthorized removal while maintaining vehicle aesthetics.
Implementation Method 1
A security plunger, being spring-loaded, is received by the plunger housing. The security plunger, responsive to a closing force imparted by a hinged door surface against the security plunger, being operable to extend and engage a plunger receiver
