Collapsible Work Stand Rails for Secure Miter Saw Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work support stands often compromise between portability, secure mounting of miter saws, and ease of shipping and storage, resulting in bulky designs that are difficult to handle.
Innovation Solution
A work support stand with a pair of support legs, elongated rails, and an extendable workpiece support, featuring a tool mount with engagement members that secure to the rails in a press fit manner, allowing for collapsible and modular design for efficient packaging and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanisms are added to securely mount miter saws and enable portability, then the functionality and secure mounting capability are improved, but the work support stand becomes bulky and difficult to ship, display, and store
Solution Approach 1:
The work support stand is divided into modular components including a collapsible frame with telescopic legs, separate tool mounting mechanisms, and adjustable support arms. Each component can be independently folded or detached, allowing the stand to be segmented into compact units for shipping and storage while maintaining secure mounting capability when assembled
Solution Approach 2:
The telescopic legs employ a nested structure where inner leg sections are inserted within outer leg sections. When collapsed, the legs nest together to minimize volume. The tool mounting mechanisms and support arms can also be positioned to nest within the overall frame structure, reducing the stand's footprint for storage and shipping while preserving full functionality when deployed
2Ease of operation
If the work support stand is designed to be portable and collapsible, then ease of shipping and storage is improved, but the structural complexity and difficulty of securing tools increases
Solution Approach 1:
The stand employs dynamic telescopic leg mechanisms with lockable joints that can be quickly extended and locked into position. The tool mounting arms feature adjustable, movable joints that can be positioned and secured at various angles. These dynamic elements provide portability through easy collapse while maintaining secure tool mounting through engineered locking features and friction-based positioning mechanisms
Solution Approach 2:
The telescopic legs incorporate self-locking mechanisms that automatically engage when extended, eliminating the need for complex manual fastening. The tool mounting arms use friction-based or spring-loaded retainers that automatically secure tools when placed in position. These self-service features reduce structural complexity by eliminating the need for numerous separate fasteners and adjustment mechanisms

AI summary
A work support includes a pair of support legs, a first elongated rail and a second elongated rail each extending between and being coupled to the pair of support legs and spaced apart from one another, and an extendable workpiece support comprising a third elongated rail and a material support supported by the third elongated rail. The material support is movable laterally and axially relative to the third elongated rail. The third elongated rail is axially movable between extended and retracted positions.
