Detachable Workpiece Support for Pickup Tailgate Step
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-up truck tailgate systems lack a dedicated support structure for workpieces, risking damage to the tailgate when used as a work surface for tasks like drilling or cutting.
Innovation Solution
A workpiece support apparatus comprising a retractable step assembly with attached workpiece support bars and risers, which extend rearward from the tailgate when open, providing a secure surface for workpieces while preventing damage to the tailgate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tailgate is used as a work surface for drilling or cutting, then work accessibility is improved, but the tailgate is damaged
Solution Approach 1:
The patent introduces a retractable step assembly with a work surface as an intermediary structure between the user and the tailgate. This mediator provides a dedicated surface for drilling and cutting operations, preventing direct contact between tools and the tailgate, thereby eliminating damage while maintaining work accessibility.
2Ease of operation
If a retractable step assembly is added to provide step functionality, then user access to truck bed is improved, but device complexity increases
Solution Approach 1:
The patent merges two separate functions into a single integrated assembly: the retractable step mechanism and the work surface. By combining these functions, the patent provides both step functionality for accessing the truck bed and a stable work surface for tasks, thereby improving user access without proportionally increasing complexity.
Solution Approach 2:
The retractable step assembly serves multiple functions: it provides a step for climbing into the truck bed, and when extended, its top surface serves as a stable work surface for drilling, cutting, or other tasks. This multi-functionality addresses multiple user needs with a single device, improving accessibility while managing complexity efficiently.
3Object-affected harmful factors
If workpiece support structure is added to protect tailgate, then tailgate protection is improved, but device complexity increases
Solution Approach 1:
The patent combines the workpiece support function with the existing retractable step assembly. The top surface of the step assembly serves dual purposes: as a step for access and as a support structure for workpieces. This merging approach provides tailgate protection without adding a separate, complex support structure.
Solution Approach 2:
The step assembly is designed to serve multiple functions: providing a step for climbing into the truck bed and simultaneously serving as a workpiece support surface. This multi-functionality ensures tailgate protection during drilling or cutting operations while avoiding the need for additional dedicated support structures, thereby managing device complexity.

AI summary
A workpiece support is provided for a pickup truck tailgate. The tailgate includes a retractable step including a pair of step support members. The attachment brackets include a workpiece support bar and a riser that are attached to the step support members and to each other at a right angle. The workpiece support bar and riser may be fixedly attached to each other or attached by a pivot connector. Detachable connectors are provided to connect a workpiece support bar and riser detachably to the step support members.
