Pivoting Arm Saw Support Assembly for Vertical Alignment Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Table saws with fixed legs often result in poor vertical alignment with adjacent tables, causing cut materials to not smoothly transfer due to the lack of alignment between the saw's support platform and the adjacent surface.
Innovation Solution
A saw support assembly featuring a base member with a receiving channel for securing a saw leg, a pivotable arm member that extends to support the saw leg, and a branch member that limits the arm's pivot, allowing for adjustable alignment and secure vertical positioning, along with a kit of multiple assemblies for enhanced support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-height legs are used on table saws, then the saw structure is simple and stable, but the vertical alignment with adjacent tables cannot be adjusted causing poor alignment
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed leg into a dynamic adjustable support system. The arm member is designed to pivot between a storage position (folded against the base) and a support position (extended to support the saw leg), allowing the support assembly to adapt to different vertical alignment requirements while maintaining structural stability during operation.
Solution Approach 2:
The support assembly is segmented into distinct functional components: a base member for attachment to the saw leg, a pivotable arm member for height adjustment, and a branch member for limiting the pivot range. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability and alignment capability of the system.
2Adaptability or versatility
If the arm member can pivot freely, then the alignment adjustment range is maximized, but the saw leg cannot be securely supported at a fixed position
Solution Approach 1:
The branch member is designed to preliminarily prevent excessive pivoting of the arm member by defining a physical limit to the pivot range. The branch member includes a limiting surface that engages with a corresponding surface on the arm member when the arm reaches its maximum pivot angle, thereby preventing the arm from pivoting beyond the desired range and ensuring secure support at the fixed position.
Solution Approach 2:
The branch member acts as an intermediary element between the arm member and the base member, mediating the pivot motion by providing a mechanical stop. This intermediary component ensures that the arm member can pivot freely within the desired range for alignment adjustment while being reliably constrained at the maximum pivot position to maintain secure support.
3Stability of the object's composition
If multiple support assemblies are used, then the saw is more stable and aligned, but the device complexity and number of parts increase
Solution Approach 1:
The support assembly is designed as a universal, multi-functional unit that can be attached to any saw leg and provides both height adjustment and alignment capabilities. The standardized base member with receiving channel and attachment apertures allows the same assembly design to be used on all four legs of the saw, providing stable support and alignment without requiring different configurations for each support point.

AI summary
A saw support assembly includes a base member defining a receiving channel. The receiving channel of the base member is configured to receive a leg of a saw therein to secure the base member to the leg of the saw. An arm member is pivotably coupled to the base member. The arm member is configured to pivot towards or away from the base member. The arm member is configured to extend from the base member to support the leg of the saw to which the base member is secured. A branch member extends between the base member and the arm member. The branch member defines a first end connected with the base member and a second end connected with the support arm. The branch member is configured to limit a degree to which the arm member can pivot away from the base member.
