Solution Overview

Problem

Traditional plumber's putty causes permanent staining on porous materials like marble and granite, and can degrade plastics like ABS, limiting its compatibility and usability in plumbing installations.

Innovation Solution

A plumber's putty composition comprising a wax component, plant-derived oil, silicone oil, tack-reducing filler, and mineral filler, which omits plasticizers, ensuring stain-free and non-degrading performance on various plumbing materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional plumber's putty containing oils and mineral solvents is used, then the putty provides sealing and filling functionality, but it causes permanent staining on porous materials like marble and granite

Engineering Contradiction:

Improvesealing functionalityVSAvoidstaining on porous materials

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes traditional oil-based plasticizers and mineral solvents from the putty composition, extracting the harmful staining components while retaining the essential sealing functionality through alternative formulations

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the chemical composition parameters by substituting traditional oil-based plasticizers with alternative materials that do not cause staining, while maintaining the putty's pliability and sealing properties through modified ingredient ratios and types

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If traditional plumber's putty is used, then the putty maintains stability and pliability, but it degrades plastics like ABS

Engineering Contradiction:

Improveputty stabilityVSAvoiddegradation of plastics

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes traditional oil-based plasticizers from the formulation that are responsible for degrading plastic materials, while maintaining putty stability through alternative plasticizing mechanisms

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces intermediary substances that act as compatible mediators between the putty formulation and plastic materials, preventing direct harmful interactions while maintaining the desired sealing and filling properties

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If traditional plumber's putty with oils and solvents is used, then the putty is tacky to surfaces, but this causes permanent stains that cannot be removed

Engineering Contradiction:

Improvetackiness to surfacesVSAvoidpermanent stains

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the surface interaction parameters by changing the chemical composition to eliminate oil-based tackiness while introducing alternative mechanisms for surface adhesion that do not result in permanent staining

Inventive Principle:

Principle #35Parameter changes
