Interlocking Tailgate Utility Bar for Removable Load Ramps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loading ramps for vehicles require permanent mounting to the tailgate, increasing cost and complexity, and do not provide a secure and easy-to-use solution for loading heavy objects like ATVs and motorcycles.
Innovation Solution
An interlocking tailgate utility bar with a striker assembly and rail channel system that securely attaches to the tailgate latches, allowing for removable coupling of accessories like load ramps without modifying the tailgate, featuring a hinged design for easy storage and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If permanent mounting rails or channels are installed on the tailgate to support loading ramps, then the loading function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The utility bar serves as an intermediary component that interfaces between the existing tailgate latches and the loading ramp. Instead of modifying the tailgate structure, the utility bar attaches to the existing latches and provides the necessary mounting interface for the ramp, thus resolving the contradiction by introducing a mediating element that connects the two functional requirements.
Solution Approach 2:
The utility bar is designed with multiple functions: it attaches to the tailgate latches, provides structural support for the loading ramp, and offers universal compatibility with different latch configurations. This multi-functionality allows a single component to address both the loading support requirement and the need for simplicity in the tailgate structure.
2Ease of operation
If permanent mounting rails or channels are installed on the tailgate, then the loading function is improved, but the manufacturing cost increases
Solution Approach 1:
The loading system is segmented into separate components: the utility bar and the loading ramp. This segmentation allows each component to be manufactured independently using standard materials and processes, avoiding the need for expensive custom-built integrated tailgate modifications. The utility bar can be produced as a standalone part that interfaces with existing tailgate hardware.
Solution Approach 2:
The utility bar acts as a cost-effective intermediary that provides the necessary mounting function without requiring expensive modifications to the tailgate structure. By using this intermediate component, the system achieves the loading function at a lower manufacturing cost compared to permanently modifying the tailgate with rails or channels.
3Adaptability or versatility
If the utility bar is designed to be removable and attachable to tailgate latches, then the adaptability is improved, but the reliability of the connection may be reduced
Solution Approach 1:
The utility bar employs a dynamic attachment system that transitions between locked and unlocked states. The latch mechanism allows the utility bar to be securely fastened when engaged, providing reliable connection during use, while also allowing easy removal when needed. This dynamic capability enables the system to switch between secure attachment and removable configuration as required.
Solution Approach 2:
The utility bar and its attachment mechanism are designed as affordable, replaceable components rather than permanent fixtures. This approach prioritizes adaptability and cost-effectiveness over permanent reliability, allowing the connection to be easily made and removed while maintaining sufficient security during each use cycle. The design accepts that the connection is temporary but ensures adequate reliability for each attachment period.

AI summary
An interlocking tailgate utility bar for a vehicle having a tailgate at least partially defining a cargo area includes a top surface, a bottom surface opposite the top surface and configured to be disposed against an inner wall of the tailgate when the tailgate is in an open position, opposed front and rear side surfaces, and opposed ends. A striker assembly is disposed at each end of the opposed ends and includes a striker configured to be releasably coupled to tailgate latches located on opposed sides of the tailgate to thereby selectively releasably secure the interlocking tailgate utility bar to the tailgate. A rail channel is configured to receive an attachment device of a vehicle accessory to thereby removably couple the vehicle accessory to the interlocking tailgate utility bar and thus the vehicle.
