Removable Tailgate Connector for Tool-Free Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate connection systems for vehicles are labor-intensive to remove and resecure, especially when access to tools is limited, and may not provide a secure or vibration-resistant connection.
Innovation Solution
A connector system comprising a shank with a thread and passage, an actuator with a stop portion and void, and a retainer that moves between extended and retracted positions, allowing for tool-free installation and removal by rotating the shank between 90 and 300 degrees, and applying a compressive force for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts and tools are used to secure the tailgate, then the connection is secure and reliable, but the removal and re-securing process becomes labor intensive and requires tool access
Solution Approach 1:
The connector is divided into distinct functional segments: a shank with external threads for engagement, a retention assembly with a retainer and actuator mechanism, and a mounting bracket. This segmentation allows the connector to be manipulated and operated without requiring tools, as each segment performs a specific function that can be activated manually.
Solution Approach 2:
The connector incorporates a self-servicing mechanism where the actuator (such as a button or lever) allows the user to manually release the retainer from the engaged position. This self-service feature eliminates the need for external tools to remove the tailgate, as the connector can be operated directly by the user through the integrated actuator mechanism.
2Reliability
If traditional bolts are used to attach the tailgate, then the connection is stable and vibration-resistant, but the installation and removal process is time consuming
Solution Approach 1:
The connector transitions from a static bolted connection to a dynamic system where the retainer can move between engaged and disengaged positions. The actuator mechanism enables quick transformation between these states, allowing rapid installation and removal of the tailgate while maintaining connection stability when engaged. The spring-loaded or cam-based actuator provides dynamic control over the retention state.
Solution Approach 2:
The connector changes the operational parameters from threaded rotation (requiring multiple turns) to linear actuation (requiring a single pushing or lifting motion). This parameter change from rotational to linear movement significantly reduces the time required for installation and removal while maintaining the same level of connection stability through the threaded engagement of the shank.
3Device complexity
If a simple retainer design is used, then the device complexity is reduced, but the connection may not provide sufficient vibration resistance
Solution Approach 1:
The connector merges multiple functions into a single integrated assembly: the shank provides threaded engagement for secure connection, the retainer provides lateral retention and vibration resistance, and the actuator provides manual operation capability. This merging of functions into one unified connector design achieves vibration resistance without significantly increasing overall device complexity, as all components work together in a coordinated manner.
Solution Approach 2:
The retainer and actuator mechanisms are nested within or around the shank structure. The retainer may be positioned in a groove or channel on the shank, and the actuator is integrated into the same assembly. This nested arrangement allows the connector to provide enhanced vibration resistance through multiple retained components while maintaining a compact and relatively simple overall structure.

AI summary
A connector for a removable tailgate includes a shank, an actuator and a retainer. The shank has a thread, a passage and an opening from the exterior of the shank to the passage. The actuator is received within the passage and has a stop portion and a void, and is movable relative to the shank from a first position in which the void is aligned with the opening and a second position in which the stop portion is aligned with the opening. And the retainer is received in the opening and movable relative to the shank from an extended position in which the retainer extends outwardly from the exterior of the shank farther than the thread and a retracted position in which the retainer is received at least partially in the void and in which the retainer does not extend from the exterior of the shank beyond the thread.
