Plastic Grid Body With Undercut Grooves for Heavy Traffic Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lattice bodies made of plastic have limited load capacity, making them unsuitable for heavy traffic areas, and their design does not allow for expansion or displacement in the longitudinal direction or height when joined, limiting their application.
Innovation Solution
The lattice body design features offset connecting grooves and webs on the jacket, providing a uniform wall thickness and enhanced load-bearing capacity by allowing compressive and tensile forces to be transmitted through these connections, with optional edge webs for improved load transfer at the edges, and alternate hollow chambers with and without bottoms for uniform support and moisture distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lattice bodies are made of plastic to save weight and enable larger surface units, then handling and surface area are improved, but load capacity deteriorates
Solution Approach 1:
The lattice body is divided into multiple hollow chambers separated by partition walls, with each chamber providing structural support. This segmentation allows the plastic structure to achieve high load capacity through distributed structural elements while maintaining lightweight construction.
Solution Approach 2:
The lattice body combines plastic material with a complex structural configuration including hollow chambers, partition walls, and reinforcing elements. This composite approach enables the plastic structure to achieve strength levels comparable to concrete while maintaining the weight and handling advantages.
2Stability of the object's composition
If connecting grooves and webs are provided on both sides of the jacket to prevent displacement, then stability is improved, but device complexity increases
Solution Approach 1:
The connecting grooves and webs are positioned asymmetrically on opposite sides of the jacket, with the grooves offset from one another by the groove depth. This asymmetric arrangement creates a form-fitting connection that prevents displacement while maintaining uniform wall thickness and avoiding excessive structural complexity.
3Strength
If hollow chambers are provided with bottoms to increase support surface, then load bearing capacity is improved, but manufacturing complexity increases
Solution Approach 1:
The lattice body is divided into alternating hollow chambers with and without bottoms, creating a segmented structure that provides increased support surface area for load bearing while maintaining manufacturing feasibility through standardized chamber designs.

AI summary
A plantable grid structure for bearing traffic loads is described, comprising a molded body (1) that includes a shell (2) and the cavity enclosed by the shell (2) divided into individual hollow chambers (3) by partition walls (4), and with openings (5) in the chamber walls. In order to be able to bear higher traffic loads even with thin-walled plastic grid structures, it is proposed that a portion of the hollow chambers (3) distributed over the base area of the plastic molded body (1) has a base (6), that the shell (2) of the molded body (1) forms continuous, undercut connection grooves (8) over the height of the shell, and that corresponding connection webs (9) on opposite outer surfaces form connection ribs (9) to these undercut connection grooves (8).
