Trailer Coupler Interposer Locking for Simple Anti-Theft Towing Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-theft devices for trailers are either expensive or cumbersome, failing to provide a cost-effective and simple solution for securing trailers against theft.
Innovation Solution
A trailer anti-theft device comprising an interposer with a coupler interface and a tongue interface, coupled with a hitch pin that prevents sliding and additional anti-theft features to prevent substitute couplers from fitting, allowing the coupler and interposer to be stored separately to deter theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated electronic tracking systems or advanced locking mechanisms are used, then theft prevention capability is improved, but device complexity and cost increase
Solution Approach 1:
The anti-theft system is divided into separate functional components: a locking mechanism that secures the hitch receiver, a separate interposer device that blocks coupling, and an electronic alarm system that operates independently. This segmentation allows each component to be optimized for its specific function while keeping individual components simple and cost-effective.
Solution Approach 2:
An interposer device is introduced as an intermediary element between the coupler and the hitch receiver. This interposer physically blocks unauthorized coupling attempts and can be easily installed or removed without affecting other system components, providing a simple mechanical layer of security that complements electronic systems.
2Reliability
If advanced locking mechanisms with specific keys or combinations are used, then security against unauthorized access is improved, but ease of operation deteriorates
Solution Approach 1:
The locking mechanism employs a dynamic design where the lockable component can be easily moved between locked and unlocked positions using a simple actuating mechanism. This allows authorized users to quickly secure or access the hitch receiver without complex key turning or combination entering, while still maintaining strong security when locked.
3Reliability
If wheel locks that attach to trailer wheels are used, then prevention of trailer towing is improved, but ease of operation and installation deteriorates
Solution Approach 1:
The locking mechanism is designed with universal compatibility to fit standard hitch receiver dimensions, allowing it to be used on various trailer types without custom installation. The interposer device similarly uses standardized coupling interfaces, enabling easy installation and removal by users without specialized tools or expertise.

AI summary
Embodiments of the present disclosure may include a trailer anti-theft device, including an interposer having a solid square metal bar having a coupler interface, a tongue interface, and an interposer stop, the interposer may be adapted to couple to a trailer. Embodiments may also include a tongue adapter adapted to couple to a tongue of the trailer. Embodiments may also include a hitch pin having a hitch pin shaft that passes through an interposer aperture and an adapter aperture, the hitch pin prevents the interposer from sliding out of the tongue adapter. In some embodiments, the interposer may be detachably coupled to the tongue adapter and may be retained by the hitch pin in preparation to adapt to hitching the trailer to a tow vehicle for towing.
