Solution Overview

Problem

Current adhesive patches lack a 3D patterned sheet as a support that provides a visually appealing and artistically distinct appearance, and existing embossing techniques do not effectively differentiate between regions for improved usability and identification.

Innovation Solution

A 3D patterned sheet with varying physical parameters such as line heights, widths, inclination angles, and densities is used as the support, allowing for a change in flexibility and providing an artistic appearance that differs by direction and touch, preventing inappropriate use through distinct patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If simple emboss processing is applied to the support surface, then the manufacturing process is simple, but the appearance differentiation and artistic appeal are insufficient

Engineering Contradiction:
Improveemboss processing simplicityVSAvoidappearance differentiation
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent applies different embossing patterns to different regions of the support surface. Specific regions have unique line patterns, densities, and orientations that create visual differentiation and artistic appeal while maintaining the overall simplicity of the embossing process.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces asymmetric line patterns with varying orientations, densities, and spacings across different regions of the support. This asymmetry creates visually interesting patterns that differentiate various areas while still using a relatively simple embossing technique.

Inventive Principle:
Principle #4Asymmetry

2Ease of manufacture

If uniform embossing pattern is used across the support, then the manufacturing is simple, but the flexibility control and regional differentiation are limited

Engineering Contradiction:
Improveuniform pattern productionVSAvoidflexibility control
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent varies the embossing parameters (line spacing, orientation, density, depth) in different regions of the support to achieve different flexibility characteristics. This allows specific areas to be more or less flexible based on the pattern density and orientation, providing regional adaptability while using a single embossing process.

Inventive Principle:
Principle #3Local quality

3Device complexity

If no regional variation in embossing is provided, then the production process is simple, but the identification and usability distinction are insufficient

Engineering Contradiction:
Improveembossing process complexityVSAvoididentification capability
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent divides the support surface into multiple regions, each with distinct embossing patterns. This segmentation allows different areas to convey different information or serve different functional purposes, improving identification capability without significantly complicating the overall embossing process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By assigning unique embossing characteristics (pattern type, density, orientation) to specific regions, the patent enables local identification of different areas on the support, enhancing usability and information transmission while maintaining relatively simple manufacturing.

Inventive Principle:
Principle #3Local quality

AI summary

There is provided an adhesive patch using a 3D patterned sheet in which flexibility can be easily changed depending on each part requiring rigidity or flexibility and for which the final product having suitable human sense and sensibility of touch and texture is considered as the support of the adhesive patch and having not only excellent design but also excellent usability during use. An adhesive patch comprising: a support; at least a pressure-sensitive adhesive layer provided on the support; and a release liner attached on the pressure-sensitive adhesive layer so as to cover the surface of the pressure-sensitive adhesive layer, in which the support is a 3D patterned sheet characterized in that a plurality of protruded lines and recessed lines parallelly and linearly extending are formed inside and outside lines in a plurality of figures partitioned by the lines, walls of the protruded lines and recessed lines in some of the figures are formed to be inclined by different inclination angles with respect to a base part, and the protruded lines have different heights from the base part, serving as physical parameters of the protruded lines and recessed lines, toward a predetermined direction in the sheet.
