Interlocking Rubber Tiles with Male-Female Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective padding for recreational areas, such as playgrounds, is ineffective on uneven surfaces like loose gravel and becomes slippery when wet, while existing rubber tiles do not interlock, leading to uneven and hazardous surfaces.
Innovation Solution
Interlocking rubber tiles with male and female connectors that form a reservoir for adhesive, providing secure anchoring on uneven surfaces and preventing water pooling, and can be made from recycled rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional closed cell foam pads are placed on loose gravel or rocks, then coverage can be achieved, but the pads are not secured and may cause further personal injury from movement
Solution Approach 1:
The protective covering is divided into individual interlocking tiles rather than using large sheets. Each tile has male and female connectors that securely join to adjacent tiles, preventing movement on loose gravel while maintaining coverage. The segmented design allows each tile to be independently secured through interlocking mechanisms.
Solution Approach 2:
The bottom surface of each tile includes a curved or contoured configuration that conforms to uneven ground surfaces like gravel and rocks. This curvature allows the tiles to nestle into the uneven terrain, providing secure anchoring and preventing movement while maintaining protective coverage.
2Reliability
If closed cell foam pads are placed on uneven surfaces, then coverage is provided, but the pads take the shape of the underlying surface, creating an uneven activity area that may provoke falls
Solution Approach 1:
By dividing the protective covering into rigid interlocking tiles with defined edges and flat top surfaces, the system maintains a uniform activity surface. Each tile's top surface is kept flat and level, preventing the uneven contours that occur with flexible foam pads conforming to underlying terrain.
Solution Approach 2:
The tile design differentiates between the bottom surface (which may contour to ground) and the top surface (which remains flat for safety). This local quality differentiation allows the protective layer to adapt to uneven ground while maintaining a safe, even activity surface for children.
3Ease of operation
If conventional closed cell foam pads have a planar bottom and top, then positioning and coverage are maintained, but they become slippery when wet from inclement weather or sprinklers
Solution Approach 1:
The tile design incorporates different surface qualities: the bottom surface maintains a planar configuration for stable positioning, while the top surface includes textured or patterned features that provide traction when wet. This local differentiation allows the tile to remain securely positioned while preventing slippage during use.
Solution Approach 2:
The top surface of the tiles may include curved or contoured patterns that channel water away and provide friction grip. These surface variations prevent water pooling and maintain traction even when wet, while the overall tile positioning remains stable.
4Adaptability or versatility
If conventional rubber tiles are made from recycled rubber, then environmental benefits are achieved, but they do not interlock and may separate or buckle, leaving exposed areas or uneven surfaces
Solution Approach 1:
The recycled rubber is formed into segmented interlocking tiles with male and female connectors. These connectors securely join adjacent tiles, preventing separation and buckling that occur with non-interlocking conventional rubber tiles. The segmented design with positive mechanical interlocking maintains surface integrity while using recycled material.

AI summary
A tile for covering an area and which interlocks with an adjacent tile includes a main body having a top surface and a bottom surface disposed opposite the top surface. The main body has at least a first lateral side and a second lateral side. The tile includes at least one male connector situated on at least one of the first lateral side and the second lateral side of the main body and extending outwardly therefrom. The tile further includes at least one female receptacle situated on at least one of the first lateral side and the second lateral side of the main body and extending outwardly therefrom. The male connector of the tile is engageable with a female receptacle of an adjacent tile so that the tile may interlock with the adjacent tile.
