Magnetic Positioning Device With Toothed Groove And Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic positioning devices for metal work pieces are inefficient and prone to errors when setting frequently used angles, especially with heavy or large work pieces, as locking bolts tend to loosen under weight and require excessive time to adjust for varying angles.
Innovation Solution
A magnetic positioning device featuring two magnetic arms connected by a hinge with a toothed groove and a pin system that allows quick angle adjustments by 'clicking' into pre-defined indents, with a spring mechanism to secure the selected angle and resist changes due to weight, and optional magnetizable plates for controlled attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If locking bolts and nuts are used to secure the angle between arm pieces, then the connection strength is improved, but the reliability deteriorates due to loosening under continuous weight
Solution Approach 1:
The patent replaces the traditional mechanical locking system (bolts and nuts) with a magnetic field-based positioning system. The magnetic pieces generate magnetic attraction forces that automatically maintain the selected angle between arm pieces without requiring mechanical fasteners. This eliminates the loosening problem inherent in mechanical connections while maintaining strong angular positioning reliability under continuous load.
2Stability of the object's composition
If a hinge connection with locking mechanism is used, then the device can maintain fixed angles, but the ease of operation deteriorates due to time-consuming angle adjustments
Solution Approach 1:
The patent replaces mechanical locking mechanisms with a magnetic field-based angle selection system. The user can quickly adjust angles by simply moving the arm pieces, and the magnetic pieces automatically maintain the selected angle through magnetic attraction. This eliminates the time-consuming process of tightening and loosening mechanical fasteners while maintaining stable angle fixation.
Solution Approach 2:
The patent introduces a dynamic angle adjustment mechanism where the arm pieces can be freely repositioned during operation. The magnetic connection allows for quick, tool-free angle changes by simply moving the arm pieces to the desired position, where the magnetic force automatically secures the new angle. This dynamic system enables rapid adaptation to different working angles without the inertia of mechanical locking procedures.
3Ease of operation
If magnetic pieces are connected by a simple hinge, then the ease of operation is improved, but the reliability deteriorates due to angle changes under weight
Solution Approach 1:
The patent incorporates preliminary action by pre-positioning magnetic pieces at specific angles along the arm pieces. These pre-positioned magnetic pieces create predetermined angular positions that automatically engage when the arm pieces are moved to those angles. This preliminary arrangement of magnetic elements ensures that once an angle is selected, it is automatically maintained with high reliability under continuous weight, eliminating the need for additional locking mechanisms.

AI summary
A magnetic positioning device is disclosed and claimed wherein two magnetic arms are hingeably connected by an axle connector with locking bolt and nut, and an activation hole with pin inserting through the connection disks having arc-shaped toothed-groove made the selection of frequently used angles straight-forward and easy, when the pre-select angles are built to the “indents” in the toothed-groove, so that the enlarged head on the pin can be used to easily engaging to the selected angle, by pushing toward the spring located inside the hole on the disk. An optional switch is provided on the second end of the magnetic arm for easy control of the magnetic power direction.
