Honeycomb Pavement Structure for Stone Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paving stone installation methods face issues with sinking and lack of durability due to the absence of interlocking mechanisms, requiring additional joints and materials like concrete slabs or mortar, which increase costs and complexity.
Innovation Solution
A honeycomb structure with interlocking cells that support paving stones without bonding, using plastic materials resistant to wear and UV, where each cell has a foot and communication passages for linking and drainage, eliminating the need for concrete slabs or mortar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If paving stones are laid directly on sand without bonding, then installation is simple and quick, but the stones sink independently under load and lack durability
Solution Approach 1:
The honeycomb structure divides the paving surface into separate cells, each independently supporting a paving stone. This segmentation allows simple installation while preventing stones from sinking independently, as each cell acts as an individual stable unit.
Solution Approach 2:
The honeycomb structure serves as an intermediary between the sand base and the paving stones. It provides a stable framework that transfers loads evenly to the base while supporting each stone individually, eliminating the need for bonding materials.
2Reliability
If a concrete slab with mortar bed is used, then paving stones are stable and durable, but material costs and installation complexity increase
Solution Approach 1:
The invention extracts and eliminates the concrete slab and mortar bed from the traditional paving system. The honeycomb structure alone provides the necessary stability and load distribution, simplifying the system to just the honeycomb structure and paving stones.
Solution Approach 2:
The honeycomb structure acts as a thin, flexible yet strong framework that replaces the thick concrete slab. It provides structural integrity while using minimal material, reducing both complexity and material costs.
3Reliability
If adhesive or sealant is used to bond paving elements, then joints are sealed, but additional materials and processing steps are required
Solution Approach 1:
The invention converts the potential harm of open joints into a benefit by using the honeycomb walls themselves as the joint structure. The cells naturally provide separation and support without requiring additional sealing materials, maintaining reliability while improving installation speed.

AI summary
Device (1) for producing a ground surface cover, comprising at least one cellular structure (10) provided with a plurality of cells (2), each of which is delimited by walls (20, 21, 22, 23) and an upper opening plane and comprises at least one base as well as communication passages from one cell to the other, each cell (2) comprising a support (26) for supporting a pavestone (3) to be placed in the cell. The support comprises a central zone (26-1), which is centrally located in the cell, and connection elements (26-2 to 26-9) which connect the central zone to the walls by means of rigid connection arms. Cavities (26') are provided under the connection elements (26-2 to 26-9) which form bridges.
