Paving Stone Fill Blocker Wedge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In paving stone installations, gaps between stones often remain incompletely filled, leading to maintenance issues and an unaesthetic appearance, with weeds growing in these areas and filling material washing away, especially at the edges.
Innovation Solution
A fill blocker device with a body and holding component, featuring sloped lips and a stem that wedges between paving stones to secure the filling material in place, ensuring complete filling and preventing washaway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If filling material is applied to fill gaps between paving stones, then the gaps are filled and appearance is improved, but the filling material washes away from edges and is lost
Solution Approach 1:
The fill blocker is installed before the filling material is applied. The blocker creates a preliminary barrier at the gap edges that prevents the filling material from washing away, thus preventing loss before it occurs
Solution Approach 2:
The fill blocker serves as an intermediary element between the filling material and the environment (water, wind). It mediates by capturing and retaining the filling material that would otherwise wash away, preventing direct loss to the environment
2Productivity
If gaps between paving stones are left unfilled or partially filled, then installation time and material cost are reduced, but weeds grow in the gaps and maintenance increases
Solution Approach 1:
The fill blocker is installed during the initial paving process to prevent future problems. By addressing the gap filling issue upfront with the blocker, subsequent maintenance issues like weed growth are prevented before they can occur
Solution Approach 2:
The fill blocker takes preliminary anti-action by preventing weed growth and material loss before these problems can develop. It creates a barrier that stops the harmful processes (weed seeds settling, material washing away) before they can cause maintenance issues
3Ease of operation
If traditional filling methods are used without blockers, then the installation process is simple and quick, but the filling material does not remain blocked in the gaps and washes away
Solution Approach 1:
The fill blocker acts as an intermediary that remains in the gap to hold the filling material. It mediates between the filling material and external forces (water flow, wind), reliably preventing washaway while maintaining installation simplicity
Solution Approach 2:
The fill blocker is designed to be self-installing and self-retaining. Once inserted into the gap, it automatically secures itself and the filling material without requiring additional fastening or complex installation steps, maintaining ease of operation while improving reliability
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 fill blocker maintains the filling material within the gaps, improving the appearance and durability of the stoned area by ensuring complete filling and preventing weed growth, particularly at the edges, thus enhancing maintenance and aesthetic appeal.
Implementation Method 1
the lips are sloped toward the interior face relative to the stem such that the lips wedges against the side faces of the paving stones when inserted in the gap

AI summary
A fill blocker to block a gap between two paving stones each having a side face facing each other and an outer face wherein the fill blocker prevents filling material inserted between the paving blocks to escape through the gap. The fill blocker comprising a body comprising an interior face having two abutting portions and a fill-blocking portion therebetween; and a holding component extending from the interior face adapted to be wedged between the side faces. The fill blocker is adapted to have the holding component inserted in the gap between the side faces and be wedged therein with the abutting portions abutting the outer faces of the paving stones and thereby blocking the gap.
