Solution Overview

Problem

Existing stand-up packaging for food products requires costly apparatuses and additional fixing means, and the outer packaging cannot be separated from the pouch without damaging it, posing challenges in cost efficiency and consumer friendliness.

Innovation Solution

A stand-up packaging design featuring a pouch with through holes that allows the outer packaging's cover elements to be glued directly via these holes, eliminating the need for additional fixing means and enabling easy disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If stapler or mechanical fixing means are used to attach the pouch to the outer packaging, then the attachment strength is improved, but the device complexity and cost increase

Engineering Contradiction:

Improveattachment strengthVSAvoidfixing means complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the need for complex mechanical fixing means (staplers, clips, etc.) by using a simple glue application system. The pouch is attached to the outer packaging through direct gluing, removing the disturbing complex fixing mechanisms while maintaining adequate attachment strength.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the mechanical fixing system (staplers, clips, sewing) with a chemical bonding system (glue). This substitution eliminates the need for mechanical apparatuses and complex fixing means, reducing device complexity and cost while providing sufficient attachment strength.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Strength

If ultrasonic sealing or heat sealing is used to fix the pouch, then the attachment strength is improved, but the energy consumption and manufacturing cost increase

Engineering Contradiction:

Improveattachment strengthVSAvoidenergy consumption

Core Design Contradiction:

StrengthVSUse of energy by moving object

Solution Approach 1:

The invention replaces energy-intensive ultrasonic sealing or heat sealing processes with a simple glue application process. This substitution eliminates the need for ultrasonic generators or heating elements, significantly reducing energy consumption and manufacturing cost while maintaining adequate pouch attachment strength.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If additional fixing means like stapler are used, then the attachment reliability is improved, but the risk of foreign body contamination increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoidforeign body contamination risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and removes additional fixing means (staplers, clips, etc.) from the packaging system, eliminating the source of potential foreign body contamination. Only glue is used for attachment, which poses no contamination risk to the food product inside the pouch.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses a simple, single-component glue system instead of reusable mechanical fixing means. The glue provides sufficient attachment reliability without introducing any foreign body risks, and the simple application process ensures no contamination of the food product.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Stability of the object's composition

If the outer packaging is designed to securely hold the pouch, then the packaging stability is improved, but the ease of disassembly deteriorates

Engineering Contradiction:

Improvepackaging stabilityVSAvoidease of disassembly

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention creates a dynamic attachment system where the pouch can be easily removed from the outer packaging by peeling, despite the secure initial attachment. The glue provides sufficient holding strength during transport and storage but allows for simple consumer-friendly disassembly when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pouch is designed with a preliminary structure that facilitates easy removal after use. The through-hole configuration and pouch material allow consumers to easily peel the pouch away from the outer packaging without requiring tools or complex disassembly procedures.

Inventive Principle:

Principle #10Preliminary action
