Combination Peg and Wedge Stone Laying Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stone laying is labor-intensive due to the need for multiple pegs and wedges of different sizes to achieve a perfect fit for irregularly shaped stones, requiring extensive time and effort from stone masons and landscapers.
Innovation Solution
A multipurpose stone laying tool designed as a combination peg and wedge with a polypropylene structure, featuring an acute angled end and a planar end with a tapered surface at a 23-degree angle, eliminating the need for separate wedges and pegs, allowing for a perfect fit of irregularly sized and shaped stones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate pegs and wedges of different sizes are used to achieve a perfect fit for irregularly shaped stones, then the stone laying precision is improved, but the device complexity and time consumption increase
Solution Approach 1:
The patent combines the functions of a peg and a wedge into a single integrated tool with a peg end and a wedge end. This merging eliminates the need to use separate pegs and wedges of different sizes, reducing the number of tools required while maintaining the ability to achieve precise stone fits for irregularly shaped stones.
Solution Approach 2:
The combined peg-wedge tool is designed to perform multiple functions: it can be used as a peg for positioning stones, as a wedge for adjusting gaps, and can accommodate various stone shapes and sizes. This multi-functionality reduces the need for multiple specialized tools, simplifying the stone laying process while maintaining precision.
2Manufacturing precision
If multiple separate pegs and wedges are used to find the correct size for installation, then the stone fit precision is improved, but the time consumption increases
Solution Approach 1:
By combining peg and wedge functions in one tool, the worker no longer needs to search through multiple separate tools of different sizes to find the correct combination. The single combined tool provides both positioning and gap-adjustment capabilities, eliminating the time-consuming process of selecting and switching between multiple separate pegs and wedges.
3Manufacturing precision
If separate pegs and wedges are handled separately to acquire the correct gap and position, then the positioning precision is improved, but the ease of operation decreases
Solution Approach 1:
The combined peg-wedge tool allows the worker to perform both positioning and gap adjustment operations with a single tool, eliminating the need to handle and switch between separate pegs and wedges. This integration maintains positioning precision while significantly improving ease of operation by reducing the number of handling steps.
4Manufacturing precision
If workers lift and hold heavy stones for long periods while searching for correct tools, then the stone placement precision is maintained, but the physical exhaustion increases
Solution Approach 1:
The combined tool eliminates the need to search through multiple separate tools while holding heavy stones. By providing both peg and wedge functions in one tool, workers can quickly perform positioning and adjustment operations without prolonged periods of holding stones, thereby reducing physical exhaustion while maintaining placement precision.

AI summary
The present invention relates to a novel stone laying tool which allows for a perfect stone fit for irregularly sized and shaped stones. The tool is a compact, lightweight, one-piece device made from polypropylene and is positioned between two stones. More specifically, the tool has a pointed peg end and an opposite planar wedge end. The tool provides the functions of both a peg and a wedge and therefore eliminates the need to use separate wedges and pegs.
