Screwdriver Magnetic Attraction Assembly with Slidable Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screwdriver tools face issues with bolts easily detaching from the tool segment due to lack of secure magnetic attraction, and the magnetic assemblies are often discarded along with broken tool components, leading to inefficiency and waste.
Innovation Solution
A screwdriver tool design featuring a magnetic attraction assembly with a slidable sleeve and extension piece flanges that securely attach to the operation rod, allowing the magnetic attraction to remain attached during bolt operation and enabling easy removal and reattachment to another operation rod when the tool segment breaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic attraction assembly is provided to magnetically attract the bolt, then the bolt can be securely held, but the assembly becomes difficult to remove and must be discarded with broken tool components
Solution Approach 1:
The magnetic attraction assembly is segmented into separate components: the magnetic attracting loop, the slidable sleeve, and the retaining structure. This segmentation allows the magnetic assembly to be removed independently from the tool segment when broken, resolving the contradiction between secure bolt retention and ease of assembly removal.
2Adaptability or versatility
If the slidable sleeve is designed to slide forward for magnetic attraction, then bolt attraction is enabled, but the sleeve cannot be easily removed from the operation rod
Solution Approach 1:
The slidable sleeve is designed with dynamic retention mechanisms that allow it to slide forward for magnetic attraction while providing controlled removal through specific actions (uncovering the covering piece). The flanges and stop faces create a dynamic system that is secure during operation but removable when needed.
3Reliability
If the C retainer is used to retain the slidable sleeve, then removal of the sleeve is prevented, but the retainer itself becomes difficult to remove and the entire assembly must be discarded
Solution Approach 1:
The design allows the magnetic attraction assembly (slidable sleeve and magnetic attracting loop) to be recovered and reused by removing it from a broken tool segment. The covering piece can be uncovered to facilitate removal, enabling recovery of valuable magnetic components while discarding only the broken tool segment.
4Stability of the object's composition
If the slidable sleeve is made secure on the operation rod, then magnetic attraction is stable, but the assembly cannot be transferred to another operation rod
Solution Approach 1:
The magnetic attraction assembly is designed as a separable unit that can be removed from one operation rod and attached to another. The flanges and stop faces provide stable positioning during use, while the removable covering piece enables transferability between different operation rods, resolving the contradiction between stability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures secure magnetic attraction of bolts, prevents the magnetic assembly from being discarded with broken tool components, and allows for easy transfer of the magnetic assembly to another operation rod, enhancing operational efficiency and reducing waste.

AI summary
A screwdriver tool contains: an operation rod and a magnetic attraction assembly. The operation rod includes a tool segment, a neck section, a first stop face, and a second stop face. The magnetic attraction assembly includes a slidable sleeve having an accommodation section, a magnetic attracting loop, an extension piece, and a covering piece. A diameter of the neck section is less than that of the tool segment, and an inner diameter of the accommodation section is more than an outer diameter of the tool segment. The extension piece and the covering piece of the slidable sleeve have at least one flange extending to the neck section and limited between the first stop face and the second stop face. Hence, the at least one flange of the extension piece and the covering piece slides on the neck section between the first stop face and the second stop face.
