Solution Overview

Problem

Current inflatable mailers require specialized and cumbersome equipment for inflation and sealing, limiting their efficiency and scalability in packaging applications.

Innovation Solution

A system for producing inflated pouches using an inflatable web with a longitudinal fold and transverse seals, which can be inflated and sealed using conventional machinery, allowing for continuous production of inflated pouches without the need for specialized equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If specialized inflation and sealing equipment is used for inflatable mailers, then the inflation and sealing process can be completed, but the equipment is slow and cumbersome to operate and produces only one inflated mailer at a time

Engineering Contradiction:

Improveproduction speedVSAvoidequipment complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The inflatable web is divided into multiple individual pouches along its length, with each pouch having its own inflation port. This segmentation allows multiple pouches to be inflated simultaneously from a single continuous web, dramatically increasing production speed while using simpler equipment that doesn't need to handle each pouch individually

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses a continuous inflatable web that can be inflated along its entire length in one operation. The web moves continuously through the inflation and sealing process, allowing uninterrupted production of multiple pouches rather than stopping after each individual pouch is completed

Inventive Principle:

Principle #20Continuity of useful action

2Device complexity

If conventional machinery is used for production, then equipment complexity is reduced, but continuous production of inflated pouches was previously not achievable

Engineering Contradiction:

Improveequipment simplicityVSAvoidcontinuous production capability

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The invention transitions from producing single pouches in sequence to producing multiple pouches simultaneously along the longitudinal dimension of the web. By arranging inflation ports and seals along the length of the web, the system exploits the longitudinal dimension to enable parallel production of multiple pouches using conventional machinery

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A supply of inflatable pouches includes an inflatable web defining a series of inflatable chambers, a longitudinal fold in the web such that the web is configured in the form of two juxtaposed inflatable panels joined together at the longitudinal fold, and a series of transverse seals that bond the panels together to form a series of inflatable pouches between pairs of the transverse seals.
