Solution Overview
Problem
Existing cutting apparatuses for plate-shaped articles, such as gypsum boards, are inefficient in quickly and accurately cutting slats of desired dimensions, often requiring significant time and manual effort.
Innovation Solution
An adjustable board cutting apparatus with a rotating shaft and adjustable blade mounts, allowing for precise positioning of circular blades along the shaft to automatically cut plate-shaped articles into slats of predetermined widths, utilizing a motor and gear assembly for efficient cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hand-held cutting devices are used to cut plate-shaped articles into slats, then cutting accuracy can be achieved, but cutting speed is slow and productivity is low
Solution Approach 1:
The cutting device segments the plate-shaped article into multiple slats simultaneously using multiple circular blades arranged along the shaft. This allows one cutting operation to produce multiple slats at once, dramatically increasing productivity while maintaining precision through the rigid blade arrangement and adjustable positioning mechanism.
Solution Approach 2:
The patent replaces manual hand-held cutting operations with an automated mechanical cutting system. The motor-driven shaft rotates multiple circular blades that automatically cut through the plate-shaped article, eliminating the need for manual operation while maintaining cutting accuracy through precise blade positioning and alignment.
2Device complexity
If fixed blade position cutting apparatus is used, then device structure is simple, but adaptability to different slat dimensions is poor
Solution Approach 1:
The blade mounts are designed to be adjustable along the shaft, allowing the cutting apparatus to adapt to different slat dimensions. The mounts can be positioned at various locations and secured at desired positions, providing dynamic adaptability while maintaining a relatively simple overall device structure through modular components.
Solution Approach 2:
The cutting apparatus is designed with universal adaptability to cut plate-shaped articles into various slat dimensions by adjusting the blade mount positions. The same device can accommodate different cutting requirements without needing multiple specialized tools, achieving multi-functionality while keeping the device structure straightforward.
3Measurement precision
If multiple cutting operations are performed manually to achieve desired slat dimensions, then cutting precision can be maintained, but time consumption is significant
Solution Approach 1:
The plate-shaped article is divided into multiple slats in a single cutting operation using multiple circular blades mounted on the shaft. This simultaneous segmentation eliminates the need for multiple sequential cutting operations, dramatically reducing time consumption while maintaining cutting precision through the rigid blade arrangement and consistent rotational motion.
Solution Approach 2:
The cutting operation is made continuous and efficient by rotating the shaft with multiple blades that continuously engage the plate-shaped article during rotation. This eliminates the need to stop and reposition for multiple cutting operations, maintaining precision while minimizing time loss through uninterrupted cutting action.

AI summary
An apparatus for cutting a plate-shaped article into slats includes a housing having a plate-shaped article entrance for receiving the article to be cut into slats, an exit from which the slats are expelled, and a conveying path extending between the article entrance and exit. A cutting device mounted in the housing across the conveying path and which includes a rotating shaft rotatably mounted in the housing, at least one circular blade mounted to the shaft, an adjustable blade mount for each one of the at least one circular blade, mounted to the shaft so as to be translatable and adjustable along the shaft, and a motor operatively connected to the rotating shaft to drive the rotating shaft. A method for cutting a plate-shaped article into slats having predetermined widths is also provided.
