Tailgate Cargo Box Support Assembly With Upright Pivot Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo devices for trucks do not effectively retain a box in an upright position when the tailgate is in either closed or open positions, making it inconvenient to access the box without reaching into the truck bed.
Innovation Solution
A cargo support assembly comprising cross members, brackets, mounts, support tubes, and pivots that allow a box to be pivotally retained between the support tubes, ensuring it remains upright regardless of the tailgate's position, with adjustable cross members for secure attachment to the truck bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a box is placed in a truck bed, then cargo storage is achieved, but the box cannot be easily accessed when the tailgate is open because it does not remain upright
Solution Approach 1:
The box is preliminarily positioned between the support tubes in an upright orientation, and the pivot mechanism is pre-configured to automatically maintain this position. The receiving elements are designed in advance to engage with the box bottom surface, ensuring the box remains upright whether the tailgate is open or closed, eliminating the need for manual repositioning during access.
Solution Approach 2:
The pivot mechanism allows the box orientation parameter to change dynamically with tailgate position. When the tailgate moves between open and closed states, the pivot enables the box to rotate accordingly while maintaining its upright orientation relative to the ground, not the tailgate surface.
2Adaptability or versatility
If cross members are made adjustable in length, then adaptability to different truck beds is improved, but device complexity increases
Solution Approach 1:
The cross members are segmented into telescopic sections that can extend or retract to match different tailgate widths. This segmentation allows the cross members to be adjusted in length by sliding the sections relative to each other, providing adaptability to various truck bed sizes while keeping the adjustment mechanism relatively simple.
Solution Approach 2:
The cross members incorporate dynamic adjustment capabilities through telescopic design, allowing them to change length as needed. This dynamic adaptability enables the same cross member structure to serve multiple truck bed configurations without requiring multiple fixed-size components.

AI summary
A cargo support assembly includes a pair of cross members that each extends laterally across a tailgate of a truck bed. A pair of brackets is each attached to the pair of cross members and a pair of mounts is each removably attachable to a respective bracket. Each of the mounts has a receiving element and a pair of support tubes is each insertable into the receiving element in a respective one of the mounts. A pair of box pivots is each movably attachable to a respective one of the support tubes. A box is provided and each of the box pivots is attachable to the box such that the box is pivotally retained between the pair of support tubes. In this way the box is retained in an upright position whether the tailgate on the truck bed is positioned in a closed position or an open position.
