Solution Overview

Problem

Connectors used to secure veneers to cementitious backup walls often shift during the pouring of cementitious material, compromising their ability to properly secure the veneer once the material cures.

Innovation Solution

A tie system comprising a backup wall connector and a form connector that secures the veneer in place during the curing process, using engagement surfaces to prevent movement and a removable form connector that allows for reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connectors are installed to secure veneer to backup wall, then veneer connection is enabled, but connectors shift during cementitious material pouring

Engineering Contradiction:

Improveconnector positioning accuracyVSAvoidinstallation process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The form connector is installed into the form before the cementitious material is poured, securing the backup wall connector in the correct position beforehand. This preliminary positioning prevents shifting during the pouring process and ensures accurate connector placement without requiring complex adjustment mechanisms during installation.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If form connector is used to secure backup wall connector during pouring, then connector positioning is maintained, but form connector must remain in place until curing

Engineering Contradiction:

Improveconnector position stabilityVSAvoidform connector availability time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The form connector is designed to be temporarily installed during the pouring and curing process, then removed after the cementitious material has cured. This allows the form connector to be recovered and reused for subsequent forms, minimizing time loss while maintaining position stability during the critical curing period.

Inventive Principle:

Principle #34Discarding and recovering

3Manufacturing precision

If connectors are secured in place during pouring, then positioning accuracy is maintained, but removal and reuse of form connector is required

Engineering Contradiction:

Improveconnector placement precisionVSAvoidform connector reusability

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The connection system is divided into two separate components: a form connector that is temporarily installed and removed, and a backup wall connector that remains permanently embedded in the cured cementitious material. This segmentation allows the form connector to be easily removed and reused while maintaining precise connector placement during the pouring process.

Inventive Principle:

Principle #1Segmentation

AI summary

A tie system is provided for use with a wall form for a cementitious backup wall and for use with a wall tie to connect between the cementitious backup wall and a veneer. The tie system includes a backup wall connector and a form connector. The form connector is connectable to the form and secures the backup wall connector in position as the wall form is filled.
