Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current consumer goods packaging is not practical for partial consumption, as it either requires improvising to close or results in loose, damaged products due to lack of efficient resealing mechanisms, leading to difficulties in storage and transportation.

Innovation Solution

A pack design featuring at least one fold-line, mechanically perforated front and rear tear-lines, and a geometrically-shaped tab that allows for easy opening and resealing without tools, enabling separation and reconfiguration of pack portions for optimized storage and handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the pack is opened to access the consumer item, then the product becomes accessible for consumption, but the pack cannot be properly closed leading to loose packaging and product damage

Engineering Contradiction:

ImproveEase of openingVSAvoidPack closure reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The pack is divided into separable portions using perforated tear-lines, allowing the pack to be opened to access the consumer item while maintaining the ability to close and reseal the remaining portion securely. The perforated lines enable clean separation without damaging the remaining packaged content.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the entire pack is carried for storage, then the product is protected, but the pack size is excessive when only part of the product is consumed

Engineering Contradiction:

ImproveProduct protectionVSAvoidPack volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The pack allows separation into consumed and remaining portions through perforated tear-lines. Users can carry only the necessary amount after opening, reducing the volume of the moving object while maintaining product protection for the remaining content.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The remaining portion of the pack can be folded and nested within itself or stored compactly after partial consumption, minimizing the volume occupied during transportation and storage.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of operation

If the pack allows easy opening without tools, then ease of operation is improved, but the pack lacks a proper closing mechanism requiring improvisation

Engineering Contradiction:

ImproveEase of openingVSAvoidClosing mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pack incorporates both perforated tear-lines for easy opening and integrated closing flaps with adhesive strips for proper sealing. This segmentation of functions allows simple opening while providing an effective closing mechanism without requiring external tools or improvisation.

Inventive Principle:

Principle #1Segmentation

AI summary

A pack includes at least one fold-line on one of the walls of the pack; at least one mechanically perforated front tear-line running from a first extremity of the fold-line to a second extremity of the fold-line and a mechanically perforated rear tear-line running from a first extremity of the fold-line to a second extremity of the fold-line, a mechanically perforated rear tear-line defining a separation between a first portion of the pack and a second portion of the pack; and a geometrically-shaped tab integrated with the second portion of the pack, a tab that can be folded along the fold-line and tucked into the pack through an opening defined by the mechanically perforated front tear-line.
