Pivoting Saw Stand With Latch Lock for Height Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saw stands for different types of saws, such as miter saws and table saws, require varying heights for optimal operation, and existing solutions do not efficiently adapt to these height changes or facilitate easy transportation.
Innovation Solution
A tool stand with pivotable legs and a latch mechanism that allows configuration changes between miter saw, table saw, and transport modes, enabling adjustable height and easy movement by incorporating wheels and a hook mechanism for retention in different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the saw stand uses fixed-height legs, then the structure is simple and stable, but it cannot adapt to different saw types requiring different operating heights
Solution Approach 1:
The patent applies the dynamics principle by making the legs pivotable rather than fixed. Each leg can rotate about a pivot point, allowing the stand to transition between different configurations (miter saw mode with taller effective height and table saw mode with shorter effective height). This dynamic adjustment mechanism enables adaptability to different saw types while maintaining a relatively simple overall structure without requiring multiple separate stands.
2Ease of operation
If the saw stand has fixed configuration, then manufacturing is simple, but it cannot be easily transported or stored
Solution Approach 1:
The dynamics principle enables easy transportation by allowing the legs to pivot and collapse into a compact configuration. When transported, the legs can be folded against the table surface, reducing the overall footprint and making the stand easier to move and store. This dynamic folding capability is achieved through pivot joints that allow smooth transition between extended and retracted positions.
Solution Approach 2:
The segmentation principle is applied by dividing the leg structure into separate, independently pivotable segments. Each leg is a distinct component that can be individually adjusted and positioned. This segmentation allows the legs to be folded independently, creating a more compact transport configuration while maintaining structural integrity during use.
3Reliability
If the latch mechanism provides strong retention, then the legs are securely held in position, but the latch mechanism becomes more complex
Solution Approach 1:
The latch mechanism applies the self-service principle by utilizing the weight of the saw and stand components themselves to provide the retention force. When the legs are positioned in the desired configuration, gravity and the natural weight distribution create forces that push the latch elements into their engaged positions. The latch mechanism requires minimal additional force to maintain retention, as the system's own weight serves to keep everything securely in place during normal operation.

AI summary
A tool stand includes a table having a tool support surface and a plurality of legs movable relative to the table to define a first configuration and a second configuration of the tool stand. The plurality of legs includes a first leg and a second leg, each pivotable about a first axis, and the plurality of legs further includes a third leg and a fourth leg, each pivotable about a second axis parallel to the first axis. The tool stand further includes a base frame coupled to the third and fourth legs, and a latch mechanism including a latch element movable between a latched position and an unlatched position. The latch mechanism is configured to inhibit movement of each of the legs relative to the table when the latch element is in the latched position and the tool stand is in the first configuration.
