Foldable Tailgate Cover Panels for Flat Work Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The interior sides of pickup truck tailgate doors often have uneven surfaces due to manufacturing constraints and strength requirements, making them unsuitable for use as tables or workspaces when open.
Innovation Solution
A foldable and expandable tailgate cover assembly with multiple panels connected via hinge assemblies, providing a flat surface without requiring drilling into the tailgate, and featuring a latch mechanism for secure attachment, made from materials like aluminum or plastic to create a smooth, flexible, and easily stored surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tailgate door is made with standard manufacturing constraints and strength requirements, then the structural integrity is maintained, but the interior surface remains uneven and unusable for tailgating or work purposes
Solution Approach 1:
The tailgate cover is divided into multiple panels (first panel, second panel, third panel) that can be independently positioned and secured. This segmentation allows the cover to adapt to different tailgate configurations while providing a flat usable surface when needed, and can be stowed when not in use.
Solution Approach 2:
The cover transitions from a static, fixed structure to a dynamic, multi-position structure using hinge assemblies. The panels can be folded and positioned at different angles, allowing the cover to provide a flat surface when extended and to be compact when stowed, adapting to different operational needs.
2Ease of operation
If a fixed flat surface is added to the tailgate interior, then the surface usability is improved, but the device complexity and potential corrosion from drilling increase
Solution Approach 1:
The cover is divided into multiple panels that can be independently attached and detached. This allows the system to provide a flat surface when needed without permanently modifying the tailgate, reducing complexity compared to a fixed integrated solution.
Solution Approach 2:
The hinge assemblies enable the panels to be positioned and secured in various configurations without requiring permanent attachment points. The latch mechanism provides secure attachment when needed while allowing easy removal, avoiding the need for drilling into the tailgate.
3Reliability
If drilling is used to attach the cover to the tailgate, then the attachment reliability is improved, but the risk of corrosion and structural damage increases
Solution Approach 1:
The cover uses multiple attachment points distributed across the panels rather than a few drilled holes. This allows for secure attachment through clamps or magnets that contact the surface without penetrating it, eliminating corrosion risk while maintaining reliability.
Solution Approach 2:
The latch mechanism acts as an intermediary between the cover panels and the tailgate structure, providing secure attachment without direct metal-to-metal penetration. This intermediary system achieves reliable attachment through friction, magnetic force, or mechanical clamping without creating pathways for corrosion.

AI summary
A tailgate cover assembly including a first panel and a second panel fixed to a vehicle tailgate and connected to the first panel by a first hinge assembly, the first panel being pivotable with respect to the second panel. The tailgate cover may also include a third panel fixed to the second panel by a second hinge assembly and being pivotable with respect to the second panel, wherein in an extended state, the first panel and third panel provide a flat surface on the tailgate.
