Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic tool connectors are prone to damage due to vibrational disturbances when the magnet is impacted by the driven object during operation.
Innovation Solution
A magnetic tool connector design featuring a main body with first and second chambers, where a magnetic assembly is slidably coupled and movable between positions, keeping the magnet within a protected chamber to prevent impact and damage, with the magnet's engaging side flush with the abutting surface when in the protective position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnet is positioned outside the chamber to enable magnetic attraction, then the magnetic attraction function is achieved, but the magnet is vulnerable to impact and damage from the driven object
Solution Approach 1:
The magnet is nested within the chamber structure, specifically positioned in the second chamber. This nesting arrangement allows the magnet to be protected from direct impact by the driven object while still maintaining its magnetic attraction function through the chamber wall. The chamber acts as a protective enclosure that shields the magnet from harmful mechanical effects.
Solution Approach 2:
The chamber wall serves as an intermediary between the magnet and the driven object. Instead of direct contact between the magnet and the driven object, the chamber wall mediates the interaction, allowing magnetic attraction to occur through the wall while preventing direct mechanical impact on the magnet. This intermediary structure enables both magnetic function and physical protection.
2Reliability
If the magnet is positioned within the chamber to prevent impact, then the magnet is protected from damage, but the magnetic attraction effectiveness may be reduced
Solution Approach 1:
The chamber wall is designed with specific local qualities to optimize the balance between protection and magnetic performance. The wall thickness and material properties are carefully selected to provide adequate mechanical protection while maintaining sufficient magnetic permeability or conductivity to allow effective magnetic attraction. Different regions of the chamber wall may have varying properties to optimize both functions.
3Reliability
If the magnetic assembly is made movable to allow repositioning, then the magnet can be positioned to avoid impact, but the device complexity increases
Solution Approach 1:
The magnetic assembly is designed with movable components that allow the magnet to be repositioned between different locations within the chamber. This dynamic capability enables the magnet to be adjusted to optimal positions for magnetic attraction while avoiding areas vulnerable to impact. The movable design provides flexibility in positioning without requiring complete redesign of the entire assembly.

AI summary
A magnetic tool connector has a main body including a driven end and a working end. The working end defines a first chamber and second chamber. The first chamber is configured to receive an object to be driven. The second chamber has an opening at an end edge of the first chamber. The end edge of the first chamber defines an abutting surface for positioning the object within the first chamber. A magnetic assembly is slidably coupled to the main body and includes a magnet. The magnetic assembly is movable between a first position in which the magnet is located outside of the second chamber and a second position in which the magnet is located within the second chamber.
