Solution Overview

Problem

Manufacturers face inefficiencies in identifying the source of gypsum-based building materials, such as joint compounds, due to lack of unique identification methods, leading to wasted time in investigating customer complaints.

Innovation Solution

Incorporating naturally occurring tagging materials into the building materials, combined with a carrier substance, to create a unique product characteristic that can be verified through analysis, allowing for quick identification of the manufacturer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If no tagging material is added to the joint compound, then the manufacturing process remains simple and cost-effective, but the manufacturer cannot quickly identify the source of customer complaints

Engineering Contradiction:
Improvetime to investigate product sourceVSAvoidcomplexity of product identification system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The tagging material is incorporated into the joint compound during the manufacturing process, before the product reaches the customer. This preliminary action ensures that the identification marker is already present in the product, eliminating the need for later investigation to determine the manufacturer.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A tagging material containing a detectable substance acts as an intermediary between the manufacturer and the customer. This substance serves as a communication bridge that allows the manufacturer to be identified through analysis of the product or customer feedback, without requiring complex tracking systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If tagging material is incorporated into the joint compound, then the manufacturer can be quickly identified, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvereliability of product identificationVSAvoidcomplexity of manufacturing process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tagging material changes the chemical composition parameters of the joint compound by introducing a detectable substance. This parameter change enables reliable identification of the manufacturer through analysis of the product's chemical properties, while the change itself is simple to implement during manufacturing.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The joint compound becomes a composite material that includes both the original building material components and the tagging material. This composite structure maintains the functional properties of the joint compound while adding the identification capability through the integrated tagging substance.

Inventive Principle:
Principle #40Composite materials

3Measurement precision

If a detectable substance is added to the tagging material, then the manufacturer can be reliably identified through analysis, but the cost of the building material increases

Engineering Contradiction:
Improveprecision of manufacturer identificationVSAvoidcost of building material
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

Only a small, partial amount of tagging material containing the detectable substance is added to the joint compound. This partial action is sufficient to enable reliable identification through analysis while minimizing the quantity of additional substances required, thereby limiting the cost increase.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The tagging material uses inexpensive detectable substances that can be easily analyzed. The focus is on using cheap, readily analyzable materials rather than expensive permanent markers, allowing precise identification without significant cost penalty.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

At least one of these or other problems is reduced using a building material that is uniquely identifiable. A method of making an identifiable gypsum-based building product includes selecting a tagging material occurring naturally in a component of the building material and choosing a carrier substance having a high concentration of the tagging material. By selecting an amount of the carrier substance and adding it to the building material, a building product having a unique product characteristic is created. In a second embodiment of the invention, a second tagging material is combined with the first tagging material to create a unique product. In yet another embodiment of the invention, a supplemental amount of the tagging material is added to the gypsum-based composition in addition to the carrier substance. Some tagging materials are useful in a gypsum-based composition to produce a visual confirmation of the presence of the tagging material.
