Laminated Tape Label Structure for Diameter-Independent Wrap Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional tape printers limit the applicability of printed labels to objects based on their diameter, as the display portion is either unprotected or unable to be covered due to the length of the remaining label portion, leading to issues with dirt or peeling.

Innovation Solution

A tape cassette comprising a tape with multiple laminated layers, including a transparent base layer and a release layer, and a transparent cover film, which allows for the creation of labels that can be wrapped around objects with varying diameters to protect the display portion by ensuring the remaining label portion covers or overlaps with the display area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the printed label is wrapped once around the object, then the display portion is visible, but the remaining unwrapped portion is insufficient to protect the display portion from dirt or peeling when the object has a large diameter

Engineering Contradiction:

Improveprotection of display portionVSAvoidapplicability to objects of varying diameters

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The label is divided into a printed label portion and a transparent cover film portion. The transparent cover film acts as a separate protective segment that extends beyond the printed label, ensuring the display portion is covered and protected from dirt or peeling regardless of the object's diameter.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transparent cover film extends in the longitudinal direction beyond the printed label, creating an overlapping structure when wrapped around the object. This dimensional extension ensures that the display portion is covered even on large-diameter objects where a single wrap would leave the display exposed.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the remaining transparent portion is wrapped to cover the display portion on small-diameter objects, then the display portion is protected, but the transparent portion is unnecessarily long and may cause excess material

Engineering Contradiction:

Improveprotection of display portionVSAvoidexcess transparent material

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The transparent cover film is designed to extend slightly beyond the printed label in length. This partial extension ensures adequate coverage and protection of the display portion across various object diameters without creating excessive material waste, as the extension is precisely controlled to match the minimum required overlap.

Inventive Principle:

Principle #16Partial or excessive action

3Ease of manufacture

If the printed label uses a single-layer structure, then the manufacturing is simple, but the label cannot provide sufficient protection against dirt or peeling

Engineering Contradiction:

Improvesimplicity of label structureVSAvoidprotection of display portion

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The label employs a composite structure consisting of a printed label layer and a transparent cover film layer. This composite design provides enhanced protection against dirt and peeling while maintaining manufacturing simplicity through a straightforward lamination process that integrates the two functional layers.

Inventive Principle:

Principle #40Composite materials

4Reliability

If the transparent cover film extends significantly beyond the printed label, then the display portion is always protected, but the label structure becomes more complex and material usage increases

Engineering Contradiction:

Improveprotection of display portionVSAvoidlabel structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The transparent cover film extends only to the minimum necessary degree beyond the printed label to ensure protection of the display portion. This controlled partial extension avoids excessive material usage and structural complexity while still achieving the protective function across all applicable object diameters.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A tape cassette includes a tape, a transparent cover film, and an ink ribbon. The tape has a thickness in a thickness direction and a width in a width direction. The tape is configured of a plurality of laminated layers including: a transparent base layer; a background layer having a width smaller than the width of the tape in the width direction; and a release layer constituting one surface of the tape in the thickness direction. The transparent cover film is to be bonded to the tape. The ink ribbon contains ink to be transferred to one of the tape and the cover film.
