Stacked Synthetic Grass Panels With Rotation Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for constructing synthetic grass playing fields face challenges in efficiently producing, transporting, and installing large numbers of elastically yielding panels due to their size and complexity, particularly for surfaces like football fields that require thousands of panels.
Innovation Solution
A method involving the injection moulding of panels, forming stacked groups with engagement means for rotation and translation, and using a distributor vehicle for efficient transport and installation, allowing panels to be laid in a way that facilitates rapid and precise coverage of wide surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If panels are produced individually and transported separately, then each panel can be precisely manufactured, but the transport and installation process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The system segments panels into modular stacked groups of 4 panels each, with engagement means that allow the panels to be pre-assembled in a compact configuration and then rapidly deployed by rotating the entire group into position on the substrate
Solution Approach 2:
Panels are pre-assembled into stacked groups with engagement means before transport to the installation site. This preliminary assembly reduces on-site installation time significantly, as the panels are already configured and ready for rapid deployment when delivered
2Area of stationary object
If thousands of panels are transported to cover large surfaces like football fields, then complete coverage is achieved, but the logistics and transport complexity increases dramatically
Solution Approach 1:
Multiple panels are merged into single stacked groups where 4 panels are engaged together through interlocking means. This combining reduces the number of separate transport units needed and simplifies logistics while maintaining the ability to cover large areas through repeated deployment of these modular groups
3Manufacturing precision
If panels are laid individually on the substrate, then precise positioning is possible, but the installation process becomes extremely slow and labor-intensive
Solution Approach 1:
The engagement means are pre-configured on the panels during manufacturing, establishing precise geometric relationships between panels before installation. This preliminary configuration ensures that when the stacked group is rotated into position, the panels automatically achieve precise alignment and positioning on the substrate without requiring individual adjustment
Solution Approach 2:
The engagement means are designed to automatically align and position panels as the stacked group rotates into place. The geometric configuration of the engagement features causes the panels to self-align with precise positioning on the substrate, eliminating the need for manual positioning adjustments during installation

AI summary
For the construction of synthetic grass playing fields, a plurality of panels (1, 1′, 1″) are manufactured by injection molding and stacked in groups (50). Each stacked group (50) is placed on a distributor vehicle (90) moved along a covering direction (Z), so that the panels (1) which compose the group (50) are able to rotate relative to each other with respect to a main direction (X) orthogonal to the covering direction (Z), so that a row of panels is constructed.
