Paver Locking System with X-Pattern Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Porcelain pavers, despite being made thicker for improved tensile strength, still risk shattering under heavy loads and create sharp edges when broken, posing safety hazards and vandalism concerns due to their light weight and susceptibility to tampering.
Innovation Solution
A paver locking system with straps forming an X pattern on the back of the paver, secured by a bonding layer, and connected to a paver spacer, providing a hidden locking mechanism that ties pavers together, enhancing strength and preventing shattering and vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If porcelain pavers are made thicker to improve tensile strength, then strength is improved, but weight increases and susceptibility to shattering under heavy loads persists
Solution Approach 1:
The patent applies composite materials by combining porcelain pavers with a bonding layer containing fiber mesh and resin. This composite structure provides tensile strength reinforcement without significantly increasing the weight of the paver itself, as the bonding layer is applied only to the back portion of the paver rather than replacing the entire paver structure.
2Weight of moving object
If porcelain pavers are made lighter to reduce load on structures, then ease of installation is improved, but susceptibility to shattering and vandalism increases
Solution Approach 1:
The bonding layer with fiber mesh and resin creates a composite structure that reinforces the lightweight porcelain paver, preventing shattering while maintaining the lightweight characteristic. The fiber mesh acts as a reinforcement network that distributes stress across the paver.
Solution Approach 2:
The bonding layer with fiber mesh provides beforehand cushioning by creating a reinforcement structure in advance that prevents shattering before it occurs. The fiber mesh acts as a protective network that absorbs impact energy and prevents the paver from shattering under heavy loads or during vandalism.
3Object-affected harmful factors
If traditional concrete pavers are used to prevent shattering, then safety is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The bonding layer with fiber mesh is applied locally to the back portion of the porcelain paver rather than requiring the entire paver to be made of concrete or requiring complex structural support systems. This localized application provides safety reinforcement while keeping the overall device simple and easy to install.
4Ease of operation
If pavers are made self-supporting to eliminate substrate bonding, then ease of installation is improved, but load-bearing capacity under heavy loads decreases
Solution Approach 1:
The bonding layer with fiber mesh and resin creates a composite structure that enables the porcelain paver to be self-supporting while maintaining adequate load-bearing capacity. The fiber mesh reinforcement provides the necessary strength to support heavy loads without requiring full substrate bonding.
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 system prevents pavers from shattering and reduces the risk of injury by maintaining paver integrity and security, as the connected pavers form a 'raft' that resists wind uplift and tampering, enhancing safety and durability in high-traffic areas.
Implementation Method 1
a bonding layer disposed on the back portion of the paver and configured for securing the straps to the back portion of the paver
