Multi-panel hinged endgate with edge support for step panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle endgate assemblies are complex and obstruct user access when used as a step, requiring additional components like latch assemblies and linkages, which increases assembly time and complexity, and do not efficiently reduce aerodynamic drag or provide two-tier loading.
Innovation Solution
A multi-hinged endgate assembly with three interconnected panels, where the third panel is supported by the second panel without additional components, allowing unobstructed user access and reducing complexity, and configured to reduce overall height and aerodynamic drag by pivoting the second panel perpendicular to the first, enabling two-tier loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components like latch assemblies and linkages are used to support the third panel when used as a step, then the structural support and stability are improved, but the device complexity and assembly time increase
Solution Approach 1:
The patent combines the support function into the existing hinge assembly structure. The hinge assembly is designed to provide both the hinge function and the support function when the third panel is used as a step, eliminating the need for separate latch assemblies and linkages. This merging of functions reduces component count while maintaining structural support capability.
Solution Approach 2:
The hinge assembly is designed to perform multiple functions: it provides the hinge function for panel movement and simultaneously serves as a support structure when the third panel is used as a step. This multi-functionality eliminates the need for dedicated support components, reducing overall device complexity.
2Stability of the object's composition
If the endgate assembly uses a traditional multi-component support structure, then the structural stability is improved, but the assembly time and manufacturing complexity increase
Solution Approach 1:
The support structure is merged with the hinge assembly, creating a unified component that provides both hinging and support functions. This integration reduces the number of parts that need to be assembled while maintaining structural stability during step usage.
Solution Approach 2:
The hinge assembly is designed to automatically provide support functionality when the third panel is used as a step, without requiring additional components or complex assembly procedures. The existing hinge structure self-serves the dual purpose of articulation and support.
3Object-affected harmful factors
If the second panel is pivoted perpendicular to the first panel, then the overall height is reduced and aerodynamic drag is reduced, but the structural configuration becomes more complex
Solution Approach 1:
The endgate assembly uses multiple hinge axes that allow panels to pivot dynamically between different positions. The second panel can pivot perpendicular to the first panel, enabling the structure to adapt its configuration for aerodynamic efficiency while maintaining manageable complexity through controlled degrees of freedom.
Solution Approach 2:
The endgate assembly is divided into multiple independent panels (first, second, and third panels) connected by hinge assemblies. This segmentation allows each panel to be positioned independently, enabling the second panel to pivot perpendicular to the first for aerodynamic benefits without requiring complete redesign of the entire structure.

AI summary
An endgate assembly includes a first panel that has a first hinge axis, a second panel hinged to the first panel at a second hinge axis that is spaced from and generally parallel with the first hinge axis, and a third panel hinged to the second panel at a third hinge axis and pivotable about the third hinge axis from a stowed position generally parallel with the second panel to a use position generally perpendicular to the second panel. The third panel has a proximal portion and a distal portion. The proximal portion and the distal portion are divided by the third hinge axis. The second panel has a recess adjacent the third hinge axis that receives the proximal portion and has a first surface at the recess positioned to establish the use position of the third panel by contacting the proximal portion and reacting loading of the distal portion.
