Tailgate Step Support Assembly for Load Absorption and Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate support systems in vehicles do not effectively absorb loads while maintaining a compact design, limiting the size of additional structures like step pads within the tailgate.
Innovation Solution
A support assembly is integrated into the tailgate, comprising multiple support beams and channels that distribute and absorb loads, allowing for a larger step pad to be accommodated within the tailgate's inner cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing tailgate support systems are used, then the tailgate structure is simple, but the load absorption capability is insufficient and the packaging size cannot be reduced
Solution Approach 1:
The support assembly is divided into multiple discrete components including support beams, channels, and step assembly elements. Each component has a specific function and can be manufactured independently, then assembled together to form the complete support structure within the tailgate inner cavity.
Solution Approach 2:
The support assembly utilizes composite construction combining multiple materials with different properties. The support beams and channels appear to use metal or composite materials that provide both structural strength for load absorption and flexibility for integration into the tailgate structure.
2Volume of stationary object
If a larger step pad is accommodated within the tailgate, then the packaging size is reduced, but the support structure becomes more complex
Solution Approach 1:
The support assembly merges multiple functions into a single integrated structure. The support beams, channels, and step assembly are combined into one unit that provides load support, step functionality, and space optimization simultaneously, reducing the need for separate structural elements.
Solution Approach 2:
The support assembly serves multiple purposes: it provides structural support for load absorption, accommodates the step pad for user access, and optimizes the packaging volume. This multi-functional design eliminates the need for separate dedicated structures for each function.
3Ease of manufacture
If the support assembly is directly attached to the deployable step assembly, then the manufacturing and assembly ease is enhanced, but the structural complexity increases
Solution Approach 1:
The support assembly is pre-assembled with the deployable step assembly before installation into the tailgate. This preliminary assembly allows for quality control and adjustment to be performed beforehand, simplifying the final installation process and reducing on-site complexity.
Solution Approach 2:
The channels serve as intermediary components that connect the support beams to the deployable step assembly. These channels facilitate the connection by providing a standardized interface that simplifies the attachment process while distributing structural loads effectively.

AI summary
A motor vehicle includes a tailgate, a deployable step assembly movable between a stowed position and a deployed position relative to an inner cavity of the tailgate, and a support assembly within the inner cavity. The support assembly is directly attached to the deployable step assembly.
