Removable Slide Hammer Actuation Element Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide hammers have a complex and troublesome process for replacing the drive segment, which hinders quick and efficient connection of the actuation element and the drive rod.
Innovation Solution
A slide hammer design featuring a removable actuation element with a connection element, a slidable sleeve, and a locking mechanism that allows the actuation element to be quickly connected to the drive rod through a coupling space and locking groove, enabling easy detachment and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional quick screw device with guiding stem and rotary lever is used, then the connection between actuation element and drive rod is secure, but the replacement process becomes complicated and troublesome
Solution Approach 1:
The actuation element is separated from the drive rod as a removable component. The connection element on the drive rod features a locking groove that can engage with the actuation element's engagement portion, allowing the actuation element to be detached and replaced without affecting the drive rod structure.
Solution Approach 2:
The actuation element is extracted as a standalone removable component from the integrated drive rod assembly. The connection element provides a dedicated interface (locking groove) that enables the actuation element to be taken out and replaced independently, simplifying the replacement process.
2Productivity
If the actuation element is made removable for quick replacement, then the replacement speed increases, but the connection stability may be compromised
Solution Approach 1:
The connection element is pre-equipped with a locking groove that is designed to engage with the actuation element's engagement portion. This preliminary structural arrangement ensures that when the actuation element is installed, it automatically locks into place, providing stable connection without requiring additional fastening operations.
Solution Approach 2:
The actuation element fits into the connection element's locking groove structure, with the engagement portion of the actuation element nesting into the locking groove. This nested arrangement ensures secure engagement while allowing for easy insertion and removal.

AI summary
A removal apparatus of a threaded post contains: a drive rod, a connection element, an actuation element, and a slidable sleeve. The connection element includes a locking groove and a notch. The actuation element includes a fitting fringe corresponding to the connection element, a cylindrical neck having a diameter less than a diameter of the fitting fringe, and an engagement disc having a diameter more than the diameter of the cylindrical neck. The diameter of fitting fringe is equal to a diameter of the connection element. The slidable sleeve includes a coupling space having a diameter equal to the diameter of the fitting fringe and the diameter of the connection element. The slidable sleeve is slid so that the coupling space abuts against the fitting fringe and the connection element, and the engagement disc is engaged in the locking groove.
