Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable tool stands, particularly for stationary tools like miter saws and table saws, lack stability during operation, leading to instability and inconvenience due to movement under user force.
Innovation Solution
A foldable stand design with pivotable legs, adjustable support rods, and a locking mechanism that allows for multiple configurations, including a miter saw, table saw, and transport configurations, providing enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the saw stand is made from different parts which are not permanently fixed to each other to allow for transportable and collapsible design, then the stand becomes portable and collapsible, but the stand becomes unstable when the saw is in operation
Solution Approach 1:
The stand employs dynamically adjustable legs that can be positioned at multiple angles and locked into place. The legs are not permanently fixed but can be adjusted and secured to provide stability during operation, then collapsed for transport. This dynamic adjustability allows the stand to transition between portable and stable states.
Solution Approach 2:
The stand changes its structural parameters by adjusting the angle and position of the legs relative to the tabletop. By varying these geometric parameters, the stand achieves different configurations: a stable, wide-based configuration during operation and a compact, collapsed configuration for transport.
2Ease of operation
If the stand is designed to be collapsible and transportable at the same time, then the stand becomes movable, but the stand tends to move in the force direction when force is exerted on the saw
Solution Approach 1:
The stand is divided into separate segments (tabletop, legs, support members) that can be independently positioned and locked. This segmentation allows each component to be optimized for both mobility and stability, with locking mechanisms securing the segments in stable configurations during operation while allowing easy reconfiguration for transport.
Solution Approach 2:
The patent introduces locking mechanisms and support members as intermediary elements between the movable legs and the tabletop. These intermediaries provide the necessary stability during operation by securing the legs in fixed positions, while allowing the overall structure to remain reconfigurable for transport.
3Adaptability or versatility
If the stand uses non-permanently fixed parts to allow for collapsible design, then the stand becomes transportable, but the stand lacks stability when the saw is in operation
Solution Approach 1:
The stand transitions from a static, permanently fixed structure to a dynamic, adjustable structure. The legs and support members can be moved and repositioned, then locked into stable configurations during operation. This dynamic design maintains structural stability when needed while enabling collapsibility for transport.
Solution Approach 2:
The stand employs locking mechanisms that pre-position and secure the adjustable legs in stable configurations before the saw operation begins. This preliminary action of locking the legs in place ensures structural stability is established in advance, preventing movement during operation while maintaining the ability to collapse for transport.
