Tilting Blade Cover Structure for Deeper Plunge Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plunge-type cutting apparatuses have limited maximum tilt angles, restricting their cutting depth and efficiency when dealing with various materials.
Innovation Solution
The portable cutting apparatus features a tiltable main body and cover configuration, allowing the cutting blade to tilt up to 60 degrees, with an auxiliary cover that tilts independently to prevent interference with the cutting target and enhance cutting depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cover is tilted to increase cutting depth, then the cutting efficiency is improved, but the cover interferes with the cutting target material
Solution Approach 1:
The cover is divided into two independent parts: the cover main body and the auxiliary cover. The auxiliary cover can be tilted independently about a second tilt axis while the cover main body tilts about a first tilt axis. This segmentation allows the auxiliary cover to clear the cutting material path during tilting, eliminating interference while maintaining cutting depth capability
Solution Approach 2:
The auxiliary cover is positioned and configured to move in a different dimensional path compared to the cover main body. By introducing a second tilt axis distinct from the first tilt axis, the auxiliary cover follows a different spatial trajectory during tilting, allowing it to clear the cutting material without compromising the overall tilting function
2Length of moving object
If the maximum tilt angle is increased to enable deeper cuts, then the cutting depth is improved, but the cover structure becomes more complex
Solution Approach 1:
The cover is segmented into the cover main body and auxiliary cover, each with independent tilting capabilities. This segmentation enables the system to achieve greater effective tilting range and cutting depth while distributing the mechanical complexity across two simpler, independently-controlled components rather than requiring a single complex tilting mechanism
3Productivity
If the auxiliary cover tilts independently to prevent interference, then the cutting efficiency is improved, but the device complexity increases
Solution Approach 1:
The auxiliary cover is configured with dynamic tilting capability about a second tilt axis, allowing it to adjust its position independently during the cutting operation. This dynamic adjustment enables the auxiliary cover to clear the cutting material path when needed while maintaining a compact configuration during non-cutting phases, optimizing both efficiency and space utilization

AI summary
A portable cutting apparatus includes a base, a main body and a cover both on a second side of the base. The main body is displaceable relative to the base and the cover between a first position, where a blade is entirely contained in the cover, and a second position, where the blade protrudes to a first side opposite the second side beyond the base. The cover includes a cover main body, and an auxiliary cover located in proximity to the base and movable relative to the cover main body. The main body portion and the cover main body are tiltable about a first axis located on the first side of the base. The auxiliary cover is at least partially tilted about a second axis located on the second side of a surface of the base on the first side in conjunction with the tilting of the cover main body.
