Wedge-Shaped Removal Device for Gravestone Foundation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing gravestones from their foundations are time-consuming, labor-intensive, and risk causing damage to the gravestones or injuring the user, as they require breaking irreversible connections with significant effort.
Innovation Solution
A wedge-shaped device with a receptacle and partition wall is used to create and break irreversible connections by inserting it into the foundation or joint, allowing for reduced user effort and minimizing edge chipping during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a metal tool is driven into the binding agent or joint using an impact tool to break the irreversible connection, then the connection can be broken, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The device is inserted into the binding agent or joint before the gravestone is fully set, positioning itself to facilitate future removal. The wedge-shaped body with receptacle and partition wall is pre-placed in the correct orientation, so that when removal is needed, the tool simply needs to be inserted into the receptacle and leveraged, rather than requiring significant effort to break the connection from scratch
Solution Approach 2:
The device acts as an intermediary mechanism between the gravestone and foundation. It includes a receptacle that receives a lever tool and a partition wall that directs force application. This intermediary structure transforms the simple act of inserting a tool into an efficient mechanical leverage system, significantly reducing the effort and time required for removal
2Productivity
If significant effort is applied to break the irreversible connection, then the connection can be broken, but damage to the gravestone edges may occur
Solution Approach 1:
The device applies force locally and controllably through its wedge-shaped body and partition wall structure. The partition wall specifically directs the applied force away from the edges of the gravestone, concentrating the breaking action in the binding agent material itself rather than transmitting damaging forces to the gravestone edges, thus preventing chipping while maintaining removal efficiency
Solution Approach 2:
The device is positioned beforehand in a way that cushions or protects the gravestone edges from direct impact and damaging forces. The receptacle and partition wall configuration ensures that when tool force is applied, it is distributed through the binding agent in a controlled manner that prevents edge damage while still achieving connection breakdown
3Productivity
If a metal tool is driven into the binding agent using an impact tool, then the connection can be broken, but the risk of injury to the user increases
Solution Approach 1:
The device serves as a safe intermediary that eliminates the need for direct impact tool usage. Instead of driving metal tools into binding agent with hammers or impact tools, the user simply inserts a lever into the receptacle and applies gradual leverage. The partition wall and wedge-shaped body provide a safe mechanical advantage system that removes the harmful impact element entirely, maintaining removal capability while dramatically reducing injury risk
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 device enables efficient removal of gravestones with less user effort and reduced risk of injury or damage, effectively breaking the connection without chipping the edges.
Implementation Method 1

AI summary
A device for producing and subsequently breaking an irreversible connection between an object and a foundation, is formed from a wedge-shaped body. The wedge-shaped body includes at least two opposing wall surfaces that converge at an acute angle to a tip area. The wedge-shaped body has a front side, and a rear side with the tip area arranged opposite the front side. The wedge-shaped body is hollow in an area between the wall surfaces. A receptacle extends from the front side in the direction of the cavity in the wedge-shaped body between the two opposite wall surfaces. The receptacle is separated from the cavity inside the wedge-shaped body by at least one internal partition wall.
