Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular flooring systems face challenges in designing tiles that can effectively resist sudden lateral forces during sports activities, particularly in high-mechanical-stress applications like in-line skating, while maintaining a realistic manufacturing cost and ensuring a continuous, flat floor surface.
Innovation Solution
The tiles feature a monolithic support grid structure with a lattice framework and snap-fit connectors that distribute and absorb lateral forces, allowing for interlocking without direct fastening to the ground, which enhances stability and reduces wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tiles are made entirely of rigid material to resist high lateral forces, then mechanical strength is improved, but manufacturing cost increases
Solution Approach 1:
The tile combines rigid plastic material for the body with resilient rubber or foam inserts at the connection points. This composite construction allows the majority of the tile to be made from cost-effective rigid plastic while incorporating resilient elements only where needed to absorb lateral forces, thereby maintaining strength without requiring entirely rigid construction throughout the whole tile.
Solution Approach 2:
Instead of making the entire tile rigid, the invention applies rigidity locally to the main body while introducing resilience locally at the connection points. The rigid plastic provides structural integrity for the tile surface, while the resilient inserts are strategically placed only at the edges where lateral forces are applied, optimizing both performance and manufacturing cost.
2Use of energy by moving object
If resilient construction is used to absorb lateral forces, then shock absorption is improved, but relative movement between tiles increases
Solution Approach 1:
The resilient rubber or foam inserts are positioned specifically at the connection points between tiles, providing shock absorption and energy dissipation only where lateral forces are applied. The majority of the tile structure remains rigid to maintain stability and prevent relative movement, thus balancing shock absorption with structural stability.
Solution Approach 2:
The combination of rigid plastic and resilient rubber/foam creates a composite structure where the rigid portions maintain tile stability and prevent excessive movement, while the resilient inserts absorb shock and lateral forces. This composite approach allows the system to achieve both shock absorption and minimal relative movement simultaneously.
3Ease of manufacture
If tiles are directly set on ground surface without additional layers, then installation is simplified, but wear and mechanical stress resistance decrease
Solution Approach 1:
The tile incorporates its own resilient inserts directly into its structure, allowing it to absorb wear and mechanical stress independently without requiring additional protective layers. The resilient rubber or foam elements are integrated within the tile itself, enabling the tile to protect its own connection points from wear while being installed directly on the ground surface.
Solution Approach 2:
The composite construction with integrated resilient inserts provides wear resistance and mechanical stress protection directly within the tile, eliminating the need for separate protective layers. The rigid plastic body combined with resilient inserts creates a self-protecting structure that reduces wear at connection points while maintaining direct installation capability.
4Strength
If snap-fit connectors are used to interlock tiles, then connection strength is improved, but device complexity increases
Solution Approach 1:
The connector is divided into distinct functional segments: rigid plastic portions for structural connection and resilient rubber or foam inserts for absorption. This segmentation allows each portion to perform its specific function efficiently, with the rigid parts providing connection strength and the resilient inserts absorbing shock, thereby achieving strong connections without excessive overall complexity.
Solution Approach 2:
The snap-fit connector utilizes composite materials by combining rigid plastic and resilient rubber/foam in a single integrated structure. This composite connector achieves high connection strength through the rigid plastic while the resilient elements provide shock absorption, creating a functionally optimized connector that balances strength with manageable complexity.

AI summary
The tile includes a monolithic support grid structure having a rectangular configuration with four peripheral edges. The support grid structure includes a lattice framework of elongated rib members crisscrossing at right angle on the underside of the support grid structure and defining a network of cells. The support grid structure also includes a plurality of support members, each downwardly projecting from a corresponding intersection between the crisscrossing elongated rib members and having a ground-engaging distal end with a tip that is coincident with a common bottom plane. The tile includes a plurality of tile edge connectors that are positioned on the underside and made integral with the support grid structure.
