Slide Hammer Shock Absorber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slide hammers can cause discomfort and pain to users due to the sudden and intense shock experienced during impact, especially in heavy-duty applications.
Innovation Solution
A vibration-isolating slide hammer design featuring a shank with a handle and tool attachment interface, incorporating at least one shock absorber between the hammer and an axial stop to absorb shock, utilizing rubber rings or disk springs to reduce impact vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a traditional slide hammer design is used, then the tool delivers sufficient impact energy for heavy-duty applications, but the sudden stop during impact causes hand discomfort and injury
Solution Approach 1:
The patent incorporates a shock absorber assembly with elastomeric elements (rubber rings or disc springs) positioned between the hammer and the axial stop. This cushioning element is pre-installed in the path of impact, so when the hammer strikes the stop, the elastomeric material deforms to absorb and dissipate the shock energy, preventing the sudden stop that causes hand injury while still allowing full impact energy delivery to the workpiece
2Object-affected harmful factors
If a shock absorber is added to reduce impact shock, then hand comfort is improved, but the device complexity increases
Solution Approach 1:
The shock absorber assembly is nested within the existing slide hammer structure. The elastomeric elements are positioned inside the hammer body, utilizing the existing axial bore and space between the hammer and axial stop. This nested arrangement allows the shock absorption function to be integrated without significantly increasing the external dimensions or overall complexity of the tool
Solution Approach 2:
The elastomeric shock absorber elements act as an intermediary component between the hammer and the axial stop. This mediator absorbs the shock energy through elastic deformation, converting the harmful sudden impact into a more gradual force transmission, thereby protecting the user's hand while maintaining the tool's primary function
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 reduces or eliminates hand discomfort and injury by softening the shock during impact while maintaining energy delivery, making it suitable for heavy-duty applications.
Implementation Method 1
at least a first shock absorber is arranged between the hammer and the first axial stop to absorb a shock when the hammer impacts the first axial stop
Implementation Method 2
a vibration-isolating design that flexes during impact and softens the shock to a user's hand
Implementation Method 3
The first shock absorber may comprise rings selected from the group consisting of rubber rings and disk springs

AI summary
A slide hammer is proposed comprising a shank and a hammer, the hammer being slidably arranged on the shank. The shank comprises a handle at a first axial end and a tool attachment interface at a second axial end opposite from the first axial end. The shank further comprises a first axial stop for the hammer. At least a first shock absorber is arranged between the hammer and the stop to absorb a shock when the hammer impacts the stop.
