Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Adhesive tapes with print struggle to maintain optimal characteristics for antifouling properties when affixed and used, while also ensuring improved separability from rolls and transferability from ink ribbons.

Innovation Solution

The adhesive tape is designed with a layered structure comprising a tape base layer, an adhesive layer, and a separation layer, where the separation layer includes an olefin resin or acrylic resin separating agent with a long-chain alkyl group, and the transfer layer has specific solubility parameter values to enhance separability and transferability, while maintaining antifouling properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a separation layer is provided on the front surface of the tape base layer to prevent dirt and debris sticking, then antifouling properties are improved, but separability between the adhesive layer and separation layer deteriorates

Engineering Contradiction:

Improveantifouling propertiesVSAvoidseparability

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The separation layer is provided only on the front surface side of the tape base layer where antifouling properties are needed, while the adhesive layer maintains its adhesive characteristics on the rear surface. This local application of separation layer achieves antifouling protection without compromising the separability of the adhesive layer from the separation layer during feed-out.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

A specific separation layer material is introduced as an intermediary between the adhesive layer and the front surface. This separation layer acts as a mediator that provides antifouling properties while maintaining controlled adhesion with the adhesive layer, enabling easy separation during feed-out without compromising the adhesive functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the adhesive layer is made to adhere strongly to the separation layer for stable roll structure, then structural stability is improved, but separability during feed-out deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidseparability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The adhesion characteristics between the adhesive layer and separation layer are optimized by controlling the surface properties and material parameters. The separation layer is designed with specific surface energy and chemical composition that provides stable adhesion during roll formation but allows easy separation during feed-out, resolving the contradiction between structural stability and separability.

3Reliability

If the separation layer is made to adhere strongly to the ink ribbon for good transfer, then transferability is improved, but separability during feed-out deteriorates

Engineering Contradiction:

ImprovetransferabilityVSAvoidseparability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The separation layer is designed with different adhesion characteristics in different regions: strong adhesion to the ink ribbon for good transferability, and controlled adhesion to the adhesive layer for easy separability during feed-out. This local differentiation of surface properties resolves the contradiction between transferability and separability.
