Solution Overview

Problem

Existing shrink-wrapped bottle packaging lacks efficient access to individual bottles while maintaining structural rigidity, often causing damage to bottles during perforation.

Innovation Solution

A removable perforated panel assembly with alternating cuts and lands, featuring oblique-oriented perforations that avoid bottle contact during cutting, ensuring structural integrity and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional shrink-wrapped bottle packaging is used, then structural rigidity is maintained, but access to individual bottles is difficult and damage may occur during perforation

Engineering Contradiction:
Improveaccess to individual bottlesVSAvoiddamage to bottles during perforation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The shrink wrap is segmented into multiple sections with alternating cuts and lands, creating a removable panel that can be easily detached from individual bottles without requiring complete perforation of the entire wrap. This segmentation allows selective access to specific bottles while maintaining structural integrity of the remaining wrapped portions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary removable panel that mediates between the user and the bottles. This panel can be easily removed to access individual bottles, eliminating the need for direct perforation of the shrink wrap and preventing damage to the bottles during the access process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional shrink-wrapped bottle packaging is used, then structural rigidity is maintained, but access to individual bottles requires complex perforation processes

Engineering Contradiction:
Improveaccess to individual bottlesVSAvoidperforation process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The shrink wrap is divided into discrete sections with alternating cuts and lands, creating a removable panel that can be easily detached. This segmentation transforms a complex perforation process into a simple panel removal action, allowing users to access individual bottles without requiring complex perforation tools or procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable panel is pre-configured with alternating cuts and lands during manufacturing, creating a ready-to-remove access mechanism. This preliminary preparation eliminates the need for complex perforation processes at the point of use, as the panel can be simply detached from the shrink wrap to access bottles.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If perforations are made in shrink wrap to access bottles, then access is improved, but structural rigidity of the shrink wrap is compromised

Engineering Contradiction:
Improveaccess to individual bottlesVSAvoidstructural rigidity of shrink wrap
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The shrink wrap is segmented into alternating cuts and lands rather than being fully perforated. This segmentation allows the shrink wrap to maintain its structural rigidity in the remaining portions while still providing access to individual bottles through the removable panel mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality changes by creating alternating regions of cut and land patterns. The lands maintain structural integrity and rigidity, while the cuts provide access pathways. This localized differentiation allows the shrink wrap to simultaneously provide both structural strength and bottle access capability.

Inventive Principle:
Principle #3Local quality

AI summary

A perforated panel assembly is disposed in a shrink-wrapped bottle pack. The panel assembly includes a removable panel and an alternating series of cuts and lands bordering a portion of the removable panel. The alternating series of cuts and lands includes a first side perforation defining a first portion and a second portion. The first portion is positioned on a top panel of the bottle pack and the second portion is positioned on a first side of the bottle pack. The alternating series of cuts and lands further includes a second side perforation defining a first portion and a second portion. The first portion is positioned on the top panel of the bottle pack and the second portion is positioned on the first side of the bottle pack. The second portion of the first side perforation is oriented oblique to the first portion of the first side perforation.
