Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional stand-up pouches lack an integrated absorbent, leading to ineffective absorption of liquid-exuding products, which can result in product degradation and increased costs due to separate absorbent pads.

Innovation Solution

A stand-up pouch with an absorbent layer attached or integrally formed with the interior surface of the bottom, ensuring consistent absorption of liquid-exuding products without the need for separate absorbent pads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate absorbent pads are added to conventional pouches, then absorption capability is improved, but device complexity and assembly cost increase

Engineering Contradiction:

Improveabsorption capabilityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The absorbent pad is merged with the pouch body by attaching it to the interior surface of the bottom panel during the pouch forming process. This integration eliminates the need for separate assembly steps where loose pads are inserted after pouch formation, thereby reducing assembly complexity while maintaining absorption capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The absorbent pad is attached to the pouch bottom panel before the pouch is fully assembled and filled with product. This preliminary attachment ensures the absorbent is already in position and secured, eliminating the need for separate assembly steps and reducing the risk of misplacement during later handling.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If loose absorbent pads are used in conventional pouches, then absorption function is provided, but positioning reliability deteriorates during transport

Engineering Contradiction:

Improveabsorption functionVSAvoidabsorbent positioning

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The absorbent pad is permanently attached to the interior surface of the pouch bottom panel, merging it into the pouch structure. This fixation prevents the absorbent from moving during transport, storage, or when the pouch is tilted, ensuring it remains in the optimal position for absorbing liquid-exuding product throughout the product lifecycle.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A package for containing liquid-exuding product is formed of a single sheet of film that is folded and sealed at certain locations. The package can include an active member, optionally in the form of absorbent, that is heat staked or otherwise attached to a portion of the sheet of film such that the active member is located on an interior surface of a bottom of the folded and sealed package.
