Cutting Machine Ruler Rod Adjustment for Clear Scale Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary adjusting and abutting devices for material cutting machines face issues with dust accumulation and visibility of scale marks, leading to inaccurate size recognition, especially when cutting widths exceed integer measurements.
Innovation Solution
The device features a base with a guiding groove for a sliding seat, an adjusting assembly with a rotary tube and ruler rod, and a connecting and positioning piece that allows for easy recognition of size scales and precise adjustments, ensuring accurate cutting widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a transparent plate with zero position mark is used to cover the scale marks, then the cutting size can be displayed, but dust deposits and scratches cause blur and difficult recognition
Solution Approach 1:
The patent extracts the scale marks from the background fixing seat and makes them protrude forward to form an independent ruler component. This separation allows the scale marks to be displayed without being covered by a transparent plate, eliminating the problem of dust accumulation and scratches on the plate while maintaining clear visibility of the measurements.
2Ease of operation
If the zero position mark is aligned to the middle section of scale marks, then resetting can be performed, but the operator cannot intuitively recognize the current adjusted position when cutting width exceeds one integer mark
Solution Approach 1:
The patent segments the ruler into distinct integer mark sections with different lengths, where each 10mm integer mark has a longer marking line for easy identification. This segmentation allows operators to intuitively recognize the current adjusted position even when it exceeds one integer mark, as they can clearly see which 10mm section they are in and what the remainder is, eliminating confusion during resetting operations.
3Loss of information
If scale marks are made protruded for better recognition, then size recognition is enhanced, but the structure becomes more complex
Solution Approach 1:
The patent merges the scale marks with the ruler rod structure itself, making the scale marks integral protrusions on the ruler rather than separate components. This merging approach enhances size recognition by making the marks clearly visible and tactile while avoiding the complexity of additional separate marking systems or transparent plates with marks.

AI summary
An auxiliary adjusting and abutting apparatus for a machine that cuts a material has a base, a sliding seat, an adjusting assembly, a ruler rod, and a connecting and positioning piece. The sliding seat is slidably fitted on a guiding groove of the base so as to move forwardly and backwardly. The ruler rod is sleeved inside a connecting tube part and a rotary tube of the adjusting assembly. The connecting and positioning piece has a released mode and a locked mode. A locking end of the connecting and positioning piece is locked on the ruler rod in the locked mode. The ruler rod being movable back and forth in the adjusting assembly when in the released mode.
