Sawhorse Extension Rack for Multi-Board Support Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sawhorses have limited space for accommodating multiple lumber boards, making it time-consuming and energetically demanding to position and remove boards, and purchasing additional sawhorses is expensive and inefficient.
Innovation Solution
A sawhorse extension rack system with two vertical extension portions coupled to a support beam, allowing for increased capacity by sliding the extensions over the beam and positioning work-pieces in aligned openings, which can be secured with fasteners for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sawhorses are used, then the structure is simple and easy to manufacture, but the work capacity and space for accommodating multiple boards is limited
Solution Approach 1:
The extension rack is divided into separate modular components (vertical extension portions, cross-supports, beam retainers) that can be independently manufactured and assembled. This segmentation allows the system to expand work capacity without requiring a complete redesign of the entire sawhorse structure.
Solution Approach 2:
The extension rack components are designed to be universally compatible with standard sawhorse configurations. The beam retainers can slide onto various support beam sizes, and the modular design allows the same components to accommodate different board widths and heights, making the system adaptable to multiple work scenarios.
2Productivity
If multiple sawhorses are purchased to accommodate more boards, then the work capacity increases, but the cost and transportation requirements increase
Solution Approach 1:
Multiple extension portions are attached to a single sawhorse, merging the functionality of what would traditionally require multiple separate sawhorses. This consolidation allows multiple boards to be supported on one stationary base, reducing the total number of individual units needed.
Solution Approach 2:
The extension rack utilizes vertical space by extending upward from the original sawhorse surface, rather than requiring additional horizontal space that would necessitate multiple separate sawhorses. This dimensional transition maximizes the use of available three-dimensional space.
3Ease of operation
If boards are manually positioned on conventional sawhorses, then the setup is simple, but the process is time-consuming and energetically demanding
Solution Approach 1:
The extension rack with its pre-configured openings and cross-supports is prepared in advance, allowing boards to be quickly slid into place without requiring manual adjustment or repositioning during the work process. The preliminary structural arrangement facilitates efficient board handling.
Solution Approach 2:
The cross-supports act as intermediaries between the vertical extension portions and the boards, providing a stable intermediate surface that facilitates easy board placement and removal while distributing loads evenly across the structure.

AI summary
A sawhorse extension rack system incorporates two vertical extension portions coupled to a sawhorse and having openings for receiving and retaining work-pieces. The two vertical extension portions are coupled to opposing ends of the sawhorse and have a beam retainer opening that slides over a support beam extending from the sawhorse. The vertical extension portions extend up from the sawhorse and each have first and second vertical support members and one or more cross-supports to produce one or more openings to receive a work-piece. A user may slide the first and second vertical extension over the support beam and then position one or more work-pieces in the openings to increase work capacity.
