Foldable Miter Saw With Perpendicular Blade Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional miter saws are bulky and inefficient in storage and transportation due to their assembled size, and they lack precise control over the angle between the saw blade and work surface, leading to potential misalignment during sawing.
Innovation Solution
A foldable miter saw design featuring a base unit, worktable, cutting unit, adjusting member, and positioning device, where the cutting unit can be rotated between working and folded positions, ensuring the saw blade's end faces remain perpendicular to the work surface through an adjustable and locking mechanism, allowing for precise sawing and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the miter saw is packaged in an assembled state, then the structural integrity is maintained, but the volume necessary for shipping and storage increases
Solution Approach 1:
The miter saw is divided into separable components including a base unit and a cutting unit that can be detached and folded. The cutting unit can be rotated to a folded position where it occupies minimal space, allowing compact storage and transportation while maintaining structural integrity when assembled for use
2Volume of stationary object
If the cutting unit is folded to reduce storage volume, then storage efficiency improves, but the precision of saw blade orientation control deteriorates
Solution Approach 1:
Positioning devices are pre-configured at specific locations on the base unit and cutting unit. When the cutting unit is folded or assembled, these positioning devices automatically engage to pre-establish the correct perpendicular orientation between the saw blade and work surface, eliminating the need for manual angle adjustment and ensuring precision is maintained regardless of storage state
Solution Approach 2:
Positioning devices act as intermediary elements between the cutting unit and base unit. These devices include positioning protrusions and corresponding positioning recesses that mediate the relationship between components, ensuring accurate angular alignment when assembled while allowing compact folding when stored

AI summary
A foldable miter saw includes a base unit, a worktable unit rotatably mounted on the base unit and includes an axle block, a cutting unit having a rotatable member axially mounted to the axle block, an adjusting member adjustably mounted on the axle block, and a positioning device mounted on the rotatable member. Rotating the rotatable member relative to the axle block causes the cutting unit to be shifted between a working position where the adjusting member supports the positioning device in position and the end faces of the saw blade are kept perpendicular to the work surface, and a folded position where the adjusting member and the positioning device are separated from each other and one end face of the saw blade approaches the work surface.
