Solution Overview

Problem

Existing methods for attaching and removing emblems or patches from textiles, such as sewing and heat-sealing, are time-consuming, labor-intensive, and result in adhesive residue, limiting the reusability of garments and increasing costs in the apparel industry.

Innovation Solution

An emblem assembly with a mesh-based adhesive retention layer that allows for durable bonding and clean removal without residue, using a heat-activated adhesive system that incorporates a mesh layer to prevent glue from embedding in the fabric during removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heat-sealing adhesive method is used to attach emblems, then bonding durability and wash resistance are improved, but adhesive residue remains on substrate after removal

Engineering Contradiction:

Improvebonding durabilityVSAvoidadhesive residue

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The adhesive system is segmented into two distinct components: a permanent adhesive layer for bonding and a removable adhesive layer with release coating for clean removal. This segmentation allows each layer to perform its specific function - the permanent adhesive provides durable bonding while the removable adhesive with release coating prevents residue formation during removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A release coating acts as an intermediary substance applied to the removable adhesive layer. This release coating prevents the adhesive from bonding to the substrate during normal wear, yet allows for clean removal. The release coating mediates between the adhesive's bonding capability and the need for residue-free removal.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If sewing method is used to attach emblems, then bonding strength and durability are improved, but labor time and production cost increase

Engineering Contradiction:

Improvebonding strengthVSAvoidlabor time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The mechanical sewing process is replaced with a thermal adhesive bonding system. Instead of using needles and thread to mechanically join the emblem to the substrate, heat-activated adhesive layers are applied and bonded through heat pressing, significantly reducing labor time and production complexity while maintaining bonding strength.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If conventional mounting methods are used to attach emblems, then attachment speed is improved, but adhesive residue and substrate damage occur upon removal

Engineering Contradiction:

Improveattachment speedVSAvoidadhesive residue

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The adhesive system is segmented into permanent and removable adhesive layers with distinct functions. The removable adhesive layer with release coating is specifically designed to be applied quickly like conventional methods but removed cleanly without residue, solving both the speed and residue problems.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The release coating serves as an intermediary that enables quick application while preventing permanent bonding to the substrate. This allows the emblem to be attached rapidly and then removed cleanly when needed, maintaining substrate integrity and preventing adhesive residue.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An adhesive assembly can be used to join textile materials together creating a durable wash resistant. An emblem can be removed from a work shirt without leaving glue stains or residue. The shirt may be reused if emblems need to be removed or changed before the life of the garment expires. In various embodiments, a layer of mesh is incorporated into the heat activated glue on the back of the emblem. This mesh does not affect adherence to the garment. The emblem sticks just as well as without the mesh layer and with zero process changes to how the emblem is applied. The mesh allows for the complete removal of the adhesive from the garment when the patch is removed allowing the garment to be used even after the patch is removed.
