Fifth Wheel Hitch Security Lock System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fifth-wheel hitch security systems are vulnerable to unauthorized adjustment or theft due to lack of secure locking mechanisms, potentially leading to unsafe towing scenarios.
Innovation Solution
A security lock system that temporarily locks adjustable fasteners using a retractable locking bolt and locking assembly, accessible only with a paired physical key, and is ruggedized for harsh environments to protect against tampering and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustable fasteners are made accessible for easy adjustment, then ease of operation is improved, but security against unauthorized removal or adjustment deteriorates
Solution Approach 1:
A locking mechanism acts as an intermediary between the adjustable fasteners and unauthorized users. The lock requires a key to access the fasteners, mediating between legitimate adjustment needs and security requirements. This allows easy adjustment when authorized while preventing unauthorized access.
Solution Approach 2:
The fastening system is segmented into two functional parts: the adjustable fasteners for positioning and the separate locking mechanism for security. This segmentation allows the adjustment function and security function to operate independently, enabling easy adjustment when needed while maintaining security when locked.
2Reliability
If a locking mechanism is added to prevent unauthorized access, then security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to work with standard key systems and can be integrated with existing fifth wheel hitch structures. This multi-functionality approach allows the lock to serve both security and structural support functions without requiring entirely new complex systems.
Solution Approach 2:
The locking mechanism uses simple, inexpensive components such as standard keys and basic lock cylinders rather than complex electronic systems. These simpler components are easier to manufacture, maintain, and replace if needed, reducing overall system complexity.
3Ease of operation
If fasteners are made removable for easy detachment, then ease of operation is improved, but vulnerability to theft increases
Solution Approach 1:
The locking mechanism is engaged as a preliminary action before detachment occurs. By securing the fasteners with the lock before any detachment attempt, the system prevents theft while maintaining ease of legitimate detachment when the key is available to unlock first.
Solution Approach 2:
The key-based locking mechanism serves as an intermediary that must be satisfied before detachment can occur. This intermediary control mechanism allows easy detachment for authorized users with the key while blocking theft attempts from unauthorized users who cannot provide the key.

AI summary
A security lock system for a fifth wheel hitch is system that restricts access to the connection between a fifth wheel hitch and a truck bed. The system includes a receiver lock, a fifth wheel hitch, a first sleeve, a second sleeve, a lock engagement channel, and a key. The receiver lock shields a securing mechanism of the fifth wheel hitch. The receiver lock connects with a base frame of the fifth wheel hitch through the lock engagement channel. The first sleeve and the second sleeve uphold the receiver lock against the lock engagement channel. A retractable locking bolt and a locking assembly are connected to each other with the key. The retractable locking bolt and the locking assembly remain stationary as the retractable locking bolt includes a first tubular body and a first stopper, and the locking assembly includes a second tubular body and a second stopper.
