Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing balloon printing methods face issues such as fragile membranes tearing on contact with printer rollers, surface distortion leading to poor ink adhesion, and optical sensors failing to detect balloon blanks due to polymer-based materials, resulting in jamming and smudging.

Innovation Solution

A method involving coating the balloon's outer surface with a primer, attaching it to a substrate, and using two tabs - one at each end - to securely feed the balloon through a printer, mimicking a sheet of paper and preventing damage and smudging, allowing for efficient printing of images without specialist skills or equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the balloon blank is fed through the printer using conventional methods, then the printing process can be completed, but the fragile membrane tears and the surface becomes distorted

Engineering Contradiction:

Improveprinting process completionVSAvoidballoon surface integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The balloon blank is segmented into distinct functional zones: a protective cover sheet layer and a balloon envelope layer. The cover sheet acts as a sacrificial protective layer that contacts the printer rollers first, preventing direct contact between the rollers and the fragile balloon membrane, thereby preventing tears and surface distortion while allowing the printing process to complete.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cover sheet serves as an intermediary protective layer between the printer's mechanical components (rollers) and the balloon blank's fragile surface. This intermediary layer absorbs the mechanical stress and friction during the printing process, protecting the underlying balloon envelope from damage while still enabling the printing function to occur.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the balloon blank is fed through the printer, then printing can occur, but the leading edge is damaged by grabbing and pinching

Engineering Contradiction:

Improveprinting operationVSAvoidsurface damage from grabbing and pinching

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The cover sheet is attached to the balloon blank in advance, creating a protective barrier before the printing process begins. This preliminary protective measure ensures that when the leading edge of the balloon blank enters the printer and contacts the feeding mechanism, the cover sheet absorbs the grabbing and pinching forces, preventing damage to the balloon surface that would otherwise occur.

Inventive Principle:

Principle #10Preliminary action

3Extent of automation

If optical sensors detect the balloon blank, then the printing process initiates, but polymer-based materials prevent detection

Engineering Contradiction:

Improveprinting process initiationVSAvoidballoon blank detection

Core Design Contradiction:

Extent of automationVSDifficulty of detecting and measuring

Solution Approach 1:

The cover sheet is designed with optical properties that contrast with the polymer-based balloon envelope. By using materials with different optical characteristics (such as varying opacity, reflectivity, or color), the cover sheet creates an detectable signal for the printer's optical sensors, enabling automatic detection and initiation of the printing process while the underlying balloon material remains undetected due to its polymer properties.

Inventive Principle:

Principle #32Color changes

4Ease of operation

If a cover sheet is used to protect the balloon blank, then feeding uniformity improves, but gaping between layers causes feeding problems and smudging

Engineering Contradiction:

Improvefeeding uniformityVSAvoidfeeding stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cover sheet and balloon blank are merged into a single integrated assembly where the cover sheet is securely attached to the balloon envelope. This merging ensures that the layers move together as one unit through the printer, preventing gaping between layers during feeding. The integrated structure maintains feeding uniformity while eliminating the gaps that would cause feeding problems and smudging.

Inventive Principle:

Principle #5Merging (Combining)

Function Achieved in This Case

This approach minimizes jamming and smudging, ensures uniform printing, and allows for color overlay by enabling the balloon to be fed in both directions, maintaining the integrity of the balloon surface and preventing it from becoming entangled in printer mechanisms.

AI summary

The invention describes a method of printing onto a balloon that includes the steps of: coating the printable outer surface of a balloon with a primer material; attaching the balloon about a supporting substrate to form a balloon blank; flattening the printable outer surface of the balloon on the upper surface of the substrate; attaching a first tab on a first end of the balloon blank; attaching a second tab on a second end opposite the first end of the balloon blank; applying the balloon blank to a printer, via the first tab, which in use prints a first image onto the printable surface; and moving the balloon blank back through the printer via the second tab, which in use prints a second image onto the printable surface.
