Wide-Opening Tailgate With Deployable Step Platform Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tailgates lack integrated steps and deployable platforms that enhance user access and functionality, particularly in vehicles with rear storage compartments.
Innovation Solution
An integrated tailgate assembly that includes a rotatable tailgate with a deployable platform, allowing it to transition between closed, open, and step positions, featuring a cavity for the platform and angled surfaces for enhanced user access and a deployable platform that provides a stepping surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fixed tailgate is used, then the structure is simple and reliable, but user access to the storage compartment is difficult and requires lifting heavy loads
Solution Approach 1:
The tailgate is transformed from a fixed structure to a dynamic multi-position structure that can rotate between closed, open, and step positions. This allows the tailgate to adapt its configuration based on operational needs, providing ease of access when opened and structural support when positioned as a step, thereby improving user access without permanently increasing structural complexity
Solution Approach 2:
The tailgate assembly is designed to perform multiple functions: it serves as a closure when closed, provides access when open, and acts as a step when positioned at an intermediate angle. This multi-functionality eliminates the need for separate step structures, improving ease of operation while maintaining relatively simple device complexity
2Ease of operation
If the tailgate is opened fully for access, then user access is maximized, but the distance between user and storage compartment increases
Solution Approach 1:
The tailgate can be positioned at different angles including a step position that maintains proximity to the user while providing access. This dynamic positioning allows the user to access the storage compartment from a closer distance compared to fully opening the tailgate, thereby reducing the distance between user and compartment while maintaining ease of access
3Ease of operation
If a deployable platform is added to provide stepping surface, then ease of access is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The deployable platform is integrated with the tailgate assembly rather than being a separate component. The platform is coupled to the tailgate and can be deployed or stowed as needed, merging the stepping function with the existing tailgate structure. This integration simplifies manufacturing compared to adding a completely separate deployable step system

AI summary
An integrated tailgate assembly for a vehicle includes a tailgate moveable between a closed position, an open position, and a step position. The integrated tailgate assembly is configured to provide a stepping surface for a user, to assist with egress and ingress into a vehicle storage compartment. In some implementations, the integrated tailgate assembly includes a first connecting member rotatably coupled to the vehicle. In some implementations, the integrated tailgate assembly includes a second connecting member coupled to the first connecting member and the tailgate. In some implementations, the integrated tailgate assembly includes a deployable platform with a platform cover and a deployable platform grip surface, the deployable platform rotatably coupled to the tailgate and moveable between a stored position with the platform cover flush with the tailgate inner surface and a deployed position with the deployable platform grip surface providing a step.
