Tamper Resistant Cap for Tractor Trailer Plug Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The universal nature of tractor trailer connection plugs makes them vulnerable to theft, as anyone can connect to the trailer, compromising the security of the vehicle and its cargo.
Innovation Solution
A locking cap mechanism for the tractor trailer plug, controlled by a controller with wireless communication capabilities, allowing remote or authorized access through a unique code, ensuring only authorized individuals can unlock the plug.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection plug is made universal for easy connection, then the ease of operation is improved, but the security against theft deteriorates
Solution Approach 1:
The patent introduces a lock mechanism as an intermediary between the universal connection plug and the trailer. This lock acts as a mediator that allows legitimate connections while blocking unauthorized access. The lock is integrated into the cap assembly and requires authentication (key, code, or remote signal) to disengage, thereby maintaining universal compatibility while adding security against theft.
2Object-affected harmful factors
If a lock mechanism is added to the cap, then the security is improved, but the device complexity increases
Solution Approach 1:
The patent merges the lock mechanism with the existing cap assembly, integrating multiple functions into a single unified component. The lock, actuator, and cap form an integrated unit where the actuator is embedded within the cap structure. This consolidation adds security functionality while minimizing the increase in overall device complexity by reusing the cap's existing structure and mounting points.
Solution Approach 2:
The lock mechanism is designed with multi-functionality to handle various authentication methods (physical keys, coded inputs, remote wireless signals) through a single integrated system. The actuator can respond to multiple types of activation signals, making the security system versatile without requiring separate mechanisms for each authentication type, thereby controlling complexity while enhancing security.
3Ease of operation
If remote control capability is added, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The remote control system operates on a periodic or on-demand basis rather than continuously. The transceiver activates only when receiving or transmitting authentication signals, and the lock mechanism engages/disengages only when authorized commands are received. This intermittent operation pattern significantly reduces energy consumption compared to continuous monitoring or powered states, while still providing convenient remote access functionality.

AI summary
The present system generally relates to a tamper resistant cap that prevents unwanted access to a semi-tractor trailer's 7 ways connection. The system includes a controller that can be operated remotely to transmit signals to an actuator within the cap. The actuator operates a lock to secure the cap in the closed position and selectively unlock the lock to allow the cap to be opened.
