Solution Overview
Problem
Conventional circular sawing machines face difficulties in accurately and easily positioning the feeding support plate due to cumbersome operation methods and errors in distinguishing displacement values on marking rulers.
Innovation Solution
An adjustable positioning structure featuring a magnetic slider on a guide column with a micro pneumatic cylinder and display, allowing for precise movement and fixation of the feeding support plate using a control button to calculate and display displacement values, enabling easy and accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional slider and fixing lever mechanism is used to position the feeding support plate, then the structure is simple, but the operation is troublesome and positioning accuracy is poor
Solution Approach 1:
The patent replaces the conventional mechanical slider-fixing lever system with a magnetic slider system that uses magnetic force for fixation. The magnetic slider includes a magnetic element that generates magnetic attraction force to hold the feeding support plate at desired positions without requiring mechanical fixing levers, thereby simplifying operation while maintaining structural simplicity.
Solution Approach 2:
The patent introduces a display device as an intermediary between the magnetic slider and the user. The display shows the position of the feeding support plate, enabling the user to accurately determine when the plate reaches the desired position without needing to visually estimate or manually measure, thus improving positioning accuracy and ease of operation.
2Measurement precision
If a marking ruler is used to indicate displacement, then the structure is simple, but the reading accuracy is poor due to difficulty in distinguishing letters
Solution Approach 1:
The patent replaces the visual marking ruler system with an electronic display system. The display device electronically shows the displacement value or position information, eliminating the need for users to visually distinguish small letters or markings on a ruler, thereby significantly improving measurement precision while adding minimal complexity through the use of standard electronic components.
3Manufacturing precision
If the feeding support plate is manually moved along the guide column, then no additional actuation mechanism is needed, but the positioning accuracy and stability are poor
Solution Approach 1:
The patent introduces a micro pneumatic cylinder as an actuation mechanism to drive the magnetic slider along the guide column. The pneumatic cylinder provides controlled, precise movement of the feeding support plate to predetermined positions, improving positioning accuracy and stability while maintaining relatively simple device complexity through the use of a compact, standardized component.

AI summary
An adjustable positioning structure for a feeding support plate of a circular sawing machine contains a magnetic element, a micro pneumatic cylinder, and a control button. The magnetic element is accommodated in a magnetic slider which is fitted with a guide column on a material feeding side of a table of the circular sawing machine and is configured to produce a change of a magnet value of the magnetic slider when the magnetic slider moves along the guide column reciprocately, such that a displacement value of the magnetic slider is calculated and is displayed by a display on the magnetic slider. The micro pneumatic cylinder is mounted on the magnetic slider and is configured to fix or release the magnetic slider relative to the guide column. The control button is arranged on the feeding support plate and is configured to control the micro pneumatic cylinder to operate.
