Dismantlable Sawhorse Bracket With Intersecting Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable sawhorses are inefficient for supporting large planks of wood or plywood due to their limited height and storage space requirements, as they are typically short and require more room for storage and transport.
Innovation Solution
A dismantlable sawhorse design featuring a sawhorse bracket assembly with intersecting plank and support apertures that form a T or cross shape, allowing for the use of longer lumber for increased support and featuring leg cups and a circular aperture for versatile configuration, along with teeth for secure lumber retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If foldable sawhorses are used, then portability is improved, but storage space requirements increase and height is limited
Solution Approach 1:
The sawhorse is divided into separate modular components: bracket assemblies with apertures, leg lumber, and plank lumber. These segments can be disassembled and stored separately, reducing overall storage volume while maintaining portability. The bracket assemblies can be nested or stacked compactly when not in use.
Solution Approach 2:
The sawhorse design allows dynamic configuration where leg lumber can be inserted into leg cups at various positions and plank lumber can be adjusted through the T-aperture or cross-aperture. This dynamic adjustability enables compact storage when disassembled while providing extended height and span capabilities when assembled.
2Ease of operation
If conventional foldable sawhorses are used, then portability is improved, but support capability for heavy loads deteriorates
Solution Approach 1:
The bracket plate features locally optimized aperture configurations: a T-aperture with a vertical portion for support lumber and a horizontal portion for plank lumber, or a cross-aperture with multiple orientations. These localized structural features provide enhanced load-bearing capacity at critical support points while maintaining overall portability.
Solution Approach 2:
The sawhorse combines different material forms: rigid bracket plates (metal or rigid plastic) with lumber components (leg lumber and plank lumber). This composite construction provides both the strength needed for heavy load support and the portability required for easy transport and storage.
3Strength
If longer lumber is used for increased support, then support capability is improved, but device complexity increases
Solution Approach 1:
The T-aperture and cross-aperture designs serve multiple functions: they receive and secure both support lumber (for vertical strength) and plank lumber (for horizontal span). The same aperture structure accommodates different lumber lengths and orientations, reducing the need for multiple specialized components and simplifying the overall assembly process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides enhanced support for heavy loads with higher resistance to vertical deflection and allows for easier storage and transport by enabling the use of longer lumber, while maintaining stability and secure lumber retention.
Implementation Method 1
The support aperture has a height that is at least twice the width to receive a support lumber that has a high moment of inertia to provide adequate support for heavy loads placed on the sawhorse
Implementation Method 2
The leg cup channel may taper in dimension from the leg cup opening up along the leg cup channel to pinch and retain the leg lumber therein
Implementation Method 3
The teeth in the T-aperture or cross-apertures may provide increased pressure on wood configured therein by providing a reduced surface area of the aperture in contact with the wood

AI summary
A dismantlable portable sawhorse utilizes a bracket plate having a plank aperture and a support aperture that have lengths that are substantially orthogonal to each other and intersect to form a continuous aperture having an intersection space. The plank and support apertures are configured to receive various arrangements of plank lumber and support lumber, respectively. The bracket plate also has a front and back leg cup configured to receive leg lumber therein to lift the bracket plates up from the ground. The sawhorse is formed with two bracket plates configured with at least one of support and plank lumber configured in the respective apertures and extending between the two bracket plates and with leg lumber configured in each of the front and back leg cups of each bracket plate. The bracket plates may lean inward toward each other at a stand angle.
