Solution Overview

Problem

Existing stand-up packaging for food products requires costly manufacturing processes and can introduce foreign bodies into the food, and the outer packaging cannot be separated from the pouch without damaging it.

Innovation Solution

A stand-up packaging design featuring a pouch surrounded by an outer packaging with cover elements and additional elements penetrated by through holes, allowing for secure attachment via glue that extends through these holes, enabling easy disassembly without additional fixing means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical fixing means (stapler, sewing) or ultrasonic/heat sealing is used to attach the pouch to the outer packaging, then the pouch is securely fixed, but the manufacturing cost increases and foreign bodies may contaminate the food

Engineering Contradiction:

Improvesecure fixation of pouchVSAvoidmanufacturing cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces mechanical fixing means (staplers, sewing machines) and thermal sealing methods with an adhesive bonding system. The adhesive is applied through through-holes in the cover element, creating a chemical bond between the pouch and outer packaging without mechanical intervention, thereby eliminating foreign body contamination risks and reducing manufacturing complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an adhesive as an intermediary substance between the pouch and the outer packaging. This adhesive mediator creates a reliable bond without requiring direct mechanical or thermal contact, solving the contradiction by providing secure fixation through a chemical bonding mechanism that is simpler and safer than mechanical alternatives

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If mechanical fixing means or strong sealing methods are used to attach the pouch to the outer packaging, then the pouch is securely fixed, but the pouch cannot be separated without destruction

Engineering Contradiction:

Improvesecure fixation of pouchVSAvoidease of disassembly

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent creates a dynamic bonding system where the adhesive provides strong initial fixation but allows for controlled separation. The adhesive bond can be broken without destroying the pouch structure, enabling easy disassembly while maintaining secure fixation during storage and transport

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent utilizes the reversible nature of adhesive bonding by changing the bonding parameter - the adhesive maintains strong adhesion under normal conditions but can be separated without destruction when needed, allowing the package to transition between secured and disassembled states

Inventive Principle:

Principle #35Parameter changes

3Reliability

If additional fixing means (staples, sewing) are used to attach the pouch to the outer packaging, then the pouch is securely fixed, but foreign bodies may end up in the food

Engineering Contradiction:

Improvesecure fixation of pouchVSAvoidforeign body contamination

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates mechanical fixing means that could potentially contaminate food with metal staples or thread. By using adhesive bonding applied through through-holes, the system achieves secure fixation without any mechanical elements that could become foreign bodies in the food product

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a disposable adhesive bonding system that eliminates the need for durable mechanical fasteners. The adhesive provides sufficient fixation for the product lifecycle without introducing persistent foreign bodies, and the bonding mechanism is designed to be safe for food contact

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution provides a cost-effective and consumer-friendly way to assemble and disassemble the packaging, ensuring food safety and reducing manufacturing costs while allowing for easy access to the pouches without damaging the outer packaging.

Implementation Method 1

The one cover element is glued to (i.e. directly glued to) the at least one pouch via (i.e. through) the through hole. Hence, the glue which extends through the through hole of the further element can act as a kind of plug or bolt being fixedly attached or connected (i.e. directly glued) to the opposite elements

AI summary

The present invention relates to a stand-up packaging (1) for food products comprising at least one pouch (2) for carrying a food product, an outer packaging (3) having two cover elements (31,32) at least partially sandwiching the pouch (2), and at least one further element (33,2′) being at least partially sandwiched between the pouch (2) and one of the cover elements (31). The further element (33,2′) is penetrated by a through hole (22,36). The one cover element (31) is glued (G) to the pouch (2) via the through hole (22,36).
