Solution Overview

Problem

Prior art multiple wrap pressure sensitive labels face challenges in providing a 360-degree decorative design while minimizing damage to the edges and aesthetic appeal, as they often form an unappealing ridge and are prone to peeling.

Innovation Solution

A multiple wrap pressure sensitive label design featuring a first wrap portion and a second wrap portion, where the second wrap portion is wider and extends past the edges of the first, forming a lip that can be heat shrunk to enclose the first portion, allowing for a 360-degree decorative design without the ridge, and optionally includes a removable extended content portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single wrap label is used to achieve 360-degree coverage, then the label extends beyond the first end to form an angle greater than 360 degrees, but this creates an unappealing ridge and makes edges more prone to damage and peeling

Engineering Contradiction:
Improvelabel coverage areaVSAvoidedge durability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The label is divided into multiple wrap portions (first wrap portion, second wrap portion, and optionally third wrap portion) with different widths. Each wrap portion is applied in sequence around the container, with narrower portions followed by wider portions that overlap and enclose the previous portions. This segmentation eliminates the need for a single extended label that creates ridges and vulnerable edges.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If a single wrap label is used to provide decorative content, then the label can cover the container, but the ridge formed reduces aesthetic appeal and increases edge damage risk

Engineering Contradiction:
Improvedecorative coverageVSAvoidedge profile
Core Design Contradiction:
Area of stationary objectVSShape

Solution Approach 1:

The label structure implements a nested configuration where the second wrap portion (and optionally third wrap portion) extends beyond and encloses the first wrap portion. This creates a stepped, nested appearance where each subsequent wrap portion is positioned to cover the edges of previous portions, eliminating ridges and creating a clean, aesthetically pleasing profile.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If multiple wrap portions with increasing widths are used, then the label achieves 360-degree decorative design with reduced edge damage, but the label structure becomes more complex

Engineering Contradiction:
Improveedge durabilityVSAvoidlabel structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Different portions of the label have different widths tailored to specific functional requirements. The first wrap portion has a narrower width for initial application, while the second and third wrap portions have progressively wider widths to provide edge enclosure and reinforcement. This local differentiation of dimensions optimizes both durability and aesthetic appearance without requiring overly complex multi-component systems.

Inventive Principle:
Principle #3Local quality

AI summary

A multiple wrap label has a first wrap portion extending from a first end and having a first width, and a second wrap portion extending from the first wrap portion to a second end, the second wrap portion having a second width greater than the first width, the second wrap portion extending over and enclosing the first wrap portion when the label is applied to a container.
