Clampable Paving Stone Assemblies for Stable Unit Laying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cuboid-shaped paving stones are unstable when gripped from the outside, leading to slipping and making it difficult to lay them precisely and efficiently in a unit.
Innovation Solution
A stone composite comprising at least three types of approximately cuboid paving stones with irregular contours, designed to fit within a rectangular layout, where at least one outer corner region is defined by longitudinally and transversely oriented stones, allowing for clamping and stabilization without slipping.

Engineering Contradiction Analysis
1Productivity
If cuboid-shaped paving stones are used to form a laying unit, then the stones can be combined efficiently, but the stones become unstable and slip when gripped from the outside
Solution Approach 1:
The patent applies local quality by creating corner regions with a different stone arrangement than the rest of the laying unit. Specifically, corner stones are positioned to extend beyond the imaginary rectangular boundary formed by the outer edges of the laying unit, creating localized protrusions at the corners that provide grip stability without affecting the overall rectangular configuration needed for efficient laying.
2Shape
If irregularly contoured paving stones are used, then aesthetic appearance is improved, but precise joining and stable clamping become difficult

AI summary
The invention relates to a stone composite produced from a set of at least three different types of approximately cuboid paving stones (10), such as small stones, binding stones and standard stones, each having the following features: - irregularly contoured outlines in plan view; - a ratio of a top view area (F1) delimited by the outline to an area (F2) of a smallest rectangle enclosing the outline is F1 : F2 = 0.90 - 0.98, in particular approximately 0.94 - 0.96;- a ratio of a width (B) to a length (L) of the smallest rectangle enclosing the outline is B : L = 0.50 - 0.91, wherein the stone composite is formed from at least one approximately rectangular, in particular clampable, laying unit (20), wherein at least one outer corner region (30) of the laying unit (20) is defined by at least one longitudinally and at least one transversely oriented paving stone (10), wherein the longitudinally oriented paving stone 10 lies essentially parallel to a longitudinal side (40) and the transversely oriented paving stone lies essentially parallel to the adjoining transverse side (50) of the laying unit (20), and a laying unit for this purpose;
