Solution Overview

Problem

Existing three-dimensional embroidery methods fail to provide a sharp and detailed effect while maintaining productivity and workability, often resulting in damaged designs and increased time for residue removal.

Innovation Solution

The method involves layering two sheets on a fabric panel with multiple layers of embroidery, using a covering member to encapsulate the design and minimize residue exposure, allowing for efficient embroidery and reduced cleaning time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If embroidery threads are overlapped several times to create three-dimensional effect, then three-dimensional effect is achieved, but the embroidered portion becomes unclean or hardened and labor increases

Engineering Contradiction:

Improvethree-dimensional effectVSAvoidease of embroidering

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

A sheet is introduced as an intermediary tool between the fabric panel and the embroidery threads. The sheet provides a smooth, clean surface that prevents thread hardening and maintains embroidery quality while enabling three-dimensional effect through sheet layering and positioning

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If a design is separately manufactured and attached using adhesive or fixing member, then three-dimensional effect is achieved, but the design may be easily detached due to frequent laundering or contaminate or damage the fabric panel

Engineering Contradiction:

Improvethree-dimensional effectVSAvoiddesign retention

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The sheet is merged with the fabric panel through stitching along the predetermined embroidery design, creating a unified structure where the sheet becomes an integral part of the garment. This eliminates the need for separate adhesives or fixing members that could detach during laundering

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The chemical bonding method (adhesive) or separate mechanical fastening (fixing member) is replaced with a stitching-based mechanical integration that sews the sheet directly to the fabric panel, providing more reliable attachment that withstands frequent laundering

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Shape

If sheet or film residue is exposed outside the embroidery design, then three-dimensional effect is achieved, but the time for eliminating the sheet or film residue may be increased

Engineering Contradiction:

Improvethree-dimensional effectVSAvoidresidue elimination time

Core Design Contradiction:

ShapeVSLoss of time

Solution Approach 1:

The sheet is preliminarily positioned and stitched along the predetermined embroidery design before final completion, ensuring that the sheet edges are contained within the design boundaries. This preliminary action prevents residue exposure and eliminates the need for time-consuming residue removal operations

Inventive Principle:

Principle #10Preliminary action
