Solution Overview

Problem

Existing sealed packages for pourable food products are prone to damage and moisture accumulation due to their design, which can lead to issues with handling, storage, and detection of fermentation or leakage, especially when stacked or transported.

Innovation Solution

A sealed package design featuring a multilayer sheet packaging material with a unique configuration of panels and crease patterns that allows for easier gripping, reduced contact between packages, improved air circulation, and detection of internal pressure changes, preventing damage and moisture accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If packages are tightly packed for storage and transport, then storage space utilization is improved, but air circulation is reduced causing moisture accumulation and potential damage

Engineering Contradiction:
Improvestorage space utilizationVSAvoidmoisture accumulation
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The package is divided into separate panel elements (front panel, rear panel, lateral panels, top panel, bottom panel) that can be independently formed and assembled. This segmentation allows for controlled spacing and air gaps between packages when stored, preventing moisture accumulation while maintaining space efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package design incorporates three-dimensional panel configurations with specific geometric relationships (lateral panels extending between top and bottom panels, front and rear panels positioned at specific distances). This dimensional structure creates natural air circulation pathways between packages during storage and transport.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If packages are stacked or transported in groups, then transport efficiency is improved, but contact between packages increases causing damage

Engineering Contradiction:
Improvetransport efficiencyVSAvoidpackage integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The package design incorporates protective features before damage can occur. The panel construction with specific crease patterns and sealing structures provides inherent cushioning and protection against contact damage during stacking and transport, preventing damage before it happens rather than addressing it afterward.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

By segmenting the package into robust panel components with proper sealing joints, the design distributes mechanical stresses from package contact across multiple structural elements, preventing concentrated damage and maintaining integrity during efficient group transport.

Inventive Principle:
Principle #1Segmentation

3Reliability

If fermentation or leakage occurs in packaged food, then product quality deteriorates, but detection capability is reduced

Engineering Contradiction:
Improveproduct qualityVSAvoidfermentation detection
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The package design incorporates features that provide feedback about internal conditions. The panel structure with specific sealing arrangements allows for detection of pressure changes, gas accumulation, or leakage that indicate fermentation or sealing failures, enabling timely quality assessment without compromising product integrity.

Inventive Principle:
Principle #23Feedback
