Solution Overview

Problem

Existing packaging solutions for tobacco products like snus or moist snuff lack efficient and user-friendly mechanisms for opening and closing, which can lead to product exposure and spoilage, and do not provide a secure way to attach multiple articles of different attributes.

Innovation Solution

A foldable sleeve blank with specific panel configurations and fold lines, including a pull tab, catch, back cover, front, binding, slot, and middle panels, allows for the formation of a latching mechanism that securely holds articles and can be easily opened and closed, with a catch panel latched within a slot to form a package that separates into two recesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing packaging solutions are used for tobacco products, then the packaging can be simple in structure, but the opening and closing mechanism is inefficient and not user-friendly, leading to product exposure and spoilage

Engineering Contradiction:
Improveopening and closing mechanismVSAvoidproduct protection from exposure and spoilage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The packaging employs a dynamic latching mechanism with a catch panel that can move between locked and unlocked positions. The catch panel includes locking points that engage with the slot to secure the package closed, and can be released by pulling the tab to access the tobacco product. This dynamic system allows the packaging to transition between secure closed state and accessible open state, improving both ease of operation and product protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The packaging is divided into distinct functional panels: catch panel, slot panel, front panel, back panel, and bottom panel. Each panel serves a specific function in the latching mechanism or packaging structure. This segmentation allows for independent optimization of each component's function while maintaining overall system reliability and ease of use.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a secure latching mechanism is implemented, then product protection is improved, but the device complexity increases with multiple panels and fold lines

Engineering Contradiction:
Improvesecure holding of articlesVSAvoidpanel configuration and fold lines
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging utilizes a flexible blank with multiple panels connected by fold lines, allowing the structure to be collapsed into a compact form for shipping and storage, then expanded into a rigid protective structure when assembled. The flexible nature of the blank enables the complex multi-panel configuration to be manufactured efficiently while providing secure latching functionality when assembled.

Inventive Principle:
Principle #30Flexible shells and thin films

3Adaptability or versatility

If multiple articles of different attributes are packaged together, then versatility is improved, but the packaging structure becomes more complex to accommodate various product types

Engineering Contradiction:
Improvepackaging for multiple articlesVSAvoidpackaging structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging design provides a universal structure that can accommodate multiple articles of different attributes through its configurable panel system. The catch panel and slot mechanism provide universal latching functionality, while the internal configuration can be adapted to hold different types of tobacco products. The standardized panel connections and fold lines allow for versatile packaging applications without requiring fundamentally different structures for each product type.

Inventive Principle:
Principle #6Universality (Multi-functionality)
