Railing Paver with Integrated Ballast Shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof paver systems lack stability when subjected to point loads applied to railings, leading to potential instability and cracking, particularly due to inadequate structural integrity and aesthetic integration with non-railing pavers.
Innovation Solution
A precast concrete or aggregate railing paver system with integrated railing posts and pedestals, where railing pavers are thicker and heavier than non-railing pavers, featuring holes for mechanical fastening and a recessed shelf for ballast support, ensuring structural integrity and aesthetic consistency with the rest of the paver system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a railing is mounted to a standard roof paver, then the railing provides safety and structural support, but the paver may become unstable and crack when subjected to point loads
Solution Approach 1:
The patent changes the physical parameters of the paver by integrating a recessed shelf and ballast mechanism, transforming a standard thin paver into a reinforced structure capable of withstanding point loads from railings without cracking or becoming unstable
Solution Approach 2:
The patent employs ballast placed on the recessed shelf to counterbalance the point loads applied to the railing, creating a stabilizing counterweight system that prevents paver instability and cracking under load
2Reliability
If railing pavers are made thicker and heavier to provide structural support, then stability and crack resistance improve, but aesthetic consistency with non-railing pavers deteriorates
Solution Approach 1:
The patent applies local quality by creating a recessed shelf only in the railing pavers where needed for ballast support, while maintaining the overall uniform appearance of the paver system, thus providing enhanced stability locally without compromising global aesthetic consistency
Solution Approach 2:
The patent uses a recessed shelf nested within the paver structure to conceal the ballast and structural reinforcements, allowing the railing paver to maintain an aesthetically consistent appearance with non-railing pavers from a distance while providing the necessary structural support

AI summary
A paver having a length and a width. The length of the paver is about 4 feet, and the width of the paver is about 2 feet. The paver weighs about 400 pounds, and has a railing post mounted adjacent a width edge. The paver may be a part of a system of railing and non-railing pavers.
