Solution Overview

Problem

Current technologies fail to provide a practical means for consumers to easily add, remove, or modify ornamental designs on textiles without damaging the material, due to adhesive migration into fibers under varying temperatures and pressures, limiting customization and design options.

Innovation Solution

A textile product with a designated non-porous area for adhesive attachment, using pressure-sensitive adhesives that prevent migration, allowing for removable and repositionable designs, and integrating digital printing for customizable features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adhesive is used to attach designs to textile, then removability and customization are improved, but adhesive migration into fibers occurs under varying temperatures and pressures

Engineering Contradiction:

Improvecustomization capabilityVSAvoidadhesive migration

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a barrier layer as an intermediary between the adhesive and the textile substrate. This barrier layer prevents direct contact between the adhesive and textile fibers, thereby blocking adhesive migration while allowing the adhesive to perform its attachment function. The barrier layer acts as a mediator that resolves the conflict between removability and fiber protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The attachment system is segmented into distinct functional layers: the adhesive layer, the barrier layer, and the textile substrate. This segmentation allows each layer to perform its specific function independently - the adhesive provides attachment, the barrier prevents migration, and the textile provides the base material. This resolves the contradiction by separating the attachment function from the potential harm to fibers.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If permanent attachment methods are used (sewing, dyeing, embossing), then design stability is improved, but removability and customization are lost

Engineering Contradiction:

Improvedesign stabilityVSAvoidremovability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The barrier layer serves as a mediator that enables stable attachment while maintaining removability. It allows the adhesive to form a strong bond with the textile surface for stability, yet prevents permanent penetration into fibers that would make removal difficult. This intermediary structure resolves the contradiction between stability and removability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical parameters of the attachment system by introducing a barrier layer with specific permeability characteristics. This barrier layer allows the adhesive to maintain its bonding strength (stability) while preventing the chemical and physical migration that would cause permanent attachment. The parameter change in the barrier layer's properties enables both stability and removability.

Inventive Principle:

Principle #35Parameter changes

3Strength

If adhesive is applied directly to textile, then attachment strength is improved, but fiber damage and entanglement occur

Engineering Contradiction:

Improveattachment strengthVSAvoidfiber damage

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The barrier layer acts as a protective intermediary between the adhesive and the textile fibers. It allows the adhesive to achieve full attachment strength by contacting the textile surface, while simultaneously protecting the fibers from direct adhesive contact that would cause damage and entanglement. The barrier layer transmits mechanical strength while blocking harmful chemical interaction.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the potential harm of adhesive migration into a benefit by using the barrier layer to contain the adhesive's bonding action at the surface level. The adhesive's strong bonding capability is preserved and directed toward attachment, while its harmful migratory tendency is blocked by the barrier, transforming a harmful property into a controlled beneficial function.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
