Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional adhesive products lack adequate cohesiveness, leading to permanent alteration of their characteristics upon removal of an object, reduced adhesiveness, and the undesired leaving of adhesive residue on removed objects. Additionally, they are often not reusable, prone to contaminant accumulation, and lack antimicrobial properties.

Innovation Solution

A thermoset viscoelastomeric polymer derived from a thermosetting reaction media comprising isocyanate prepolymer, polyols, and plasticizers, which provides improved adhesiveness, cohesiveness, releasability, cleansability, and antimicrobial properties, allowing for multiple uses without significant degradation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional adhesive products are used for permanent attachment, then strong adhesion is achieved, but the adhesive composition permanently alters and leaves residue on removed objects

Engineering Contradiction:

ImproveadhesivenessVSAvoidcohesiveness

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

The patent changes the chemical parameters of the adhesive by using a thermoset polymer composition with specific molecular weight ranges (1,000-10,000) and controlled crosslinking density. This allows the adhesive to maintain strong bonding while enabling clean removal without permanent alteration or residue, resolving the contradiction between strong adhesion and compositional stability.

Inventive Principle:

Principle #35Parameter changes

2Strength

If conventional adhesive products are designed for single use, then initial adhesion is effective, but the product cannot be reused without substantial degradation

Engineering Contradiction:

ImproveadhesivenessVSAvoidreusability

Core Design Contradiction:

StrengthVSDuration of action of stationary object

Solution Approach 1:

The thermoset polymer adhesive maintains its adhesive properties over multiple uses through its crosslinked network structure that prevents permanent deformation. The adhesive can be removed, cleaned, and reapplied multiple times without substantial degradation, enabling continuous useful action and resolving the contradiction between initial adhesion strength and reusability duration.

Inventive Principle:

Principle #20Continuity of useful action

3Strength

If conventional adhesive products accumulate airborne contaminants, then adhesive surface area is reduced, but the product cannot be easily cleaned

Engineering Contradiction:

ImproveadhesivenessVSAvoidcleansability

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The adhesive composition is formulated to be easily cleansable with common solvents or water, allowing users to remove accumulated contaminants and restore the full adhesive surface area. This self-service cleaning capability resolves the contradiction between maintaining adhesiveness and ease of repair by enabling users to restore the adhesive's full functionality.

Inventive Principle:

Principle #25Self-service

4Object-affected harmful factors

If conventional adhesive products lack antimicrobial properties, then they attract microbes, but adding antimicrobial agents may affect adhesive performance

Engineering Contradiction:

Improvemicrobial attractionVSAvoidadhesiveness

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent creates a composite adhesive system by incorporating antimicrobial agents into the thermoset polymer matrix. The antimicrobial components (such as silver ions, zinc oxide, or organic biocides) are integrated at concentrations that provide microbial protection without significantly affecting the adhesive's bonding strength, thus resolving the contradiction between protecting against harmful factors and maintaining adhesive performance.

Inventive Principle:

Principle #40Composite materials
