Stability Members Restrict Tile Movement in Elevated Surfaces

Solution Overview

Problem

Existing structural systems for elevated building surfaces, such as decks and walkways, fail to adequately restrict relative lateral and vertical movement between surface tiles, especially in seismically active or high-wind areas, leading to increased stress on tiles and support structures.

Innovation Solution

A structural system comprising support pedestals and stability members with stabilizing arms and tile-engaging elements that are placed between adjacent surface tiles to restrict movement, using mechanical fasteners for securement, and washer forms that engage with outer edge segments to prevent horizontal and vertical displacement.

1Stability of the object's composition

If support pedestals are used to elevate surface tiles, then drainage is promoted and structural surface is provided, but relative lateral and vertical movement between adjacent surface tiles is not adequately restricted

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

Stability members are introduced as intermediary elements between adjacent surface tiles to restrict their relative movement. These stability members include stabilizing arms with tile-engaging elements that physically connect to the tiles, preventing lateral and vertical displacement without interfering with the support pedestal function of elevation and drainage.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The stability members are divided into multiple stabilizing arms, each with tile-engaging elements positioned at specific locations. This segmentation allows the system to restrict movement at multiple points across the tile assembly, providing comprehensive stabilization while maintaining the individual functionality of each component.

Inventive Principle:

Principle #1Segmentation

2Reliability

If corner portions of surface tiles are anchored to underlying support, then some movement restriction is achieved, but the anchoring is often too weak to safely and securely restrict movement

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

Instead of relying solely on vertical anchoring at corner portions, the stability members extend laterally between adjacent tiles with stabilizing arms that engage tiles at multiple points. This dimensional expansion from point anchoring to distributed lateral engagement significantly increases the strength and reliability of movement restriction.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The stability members are installed between adjacent surface tiles before final assembly completion, establishing preliminary connections that prevent movement during subsequent installation steps and use. This preliminary action ensures tiles are secured against lateral and vertical displacement from the beginning.

Inventive Principle:

Principle #10Preliminary action

3Strength

If additional pedestals are placed under central portions of tiles, then structural stability is improved, but the system still fails to restrict lateral movement between adjacent tiles

Engineering Contradiction:

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The stability members are integrated with the support pedestal system, combining the vertical support function of pedestals with the lateral stabilization function of stability members. This merged system simultaneously provides elevation, drainage, vertical support, and lateral movement restriction through a unified assembly approach.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stability members are designed to accommodate the dynamic forces encountered in seismically active areas and high-wind regions. The tile-engaging elements and stabilizing arms are configured to flex and absorb lateral forces while maintaining connection between tiles, allowing the system to respond dynamically to environmental stresses.

Inventive Principle:

Principle #15Dynamics

AI summary

A system for assembling a building surface and a building surface assembly that include surface tiles and stability members disposed between the surface tiles to restrict relative movement therebetween. The stability members may advantageously be placed between outer edge segments of the building surface tiles to restrict relative movement of adjacent surface tiles, such as due to seismic activity, vibrations, or high winds. The building surface tiles may include structures such as engagement channels for receiving and engaging the stability members.
