Solution Overview

Problem

Existing systems for applying two-component adhesives are cumbersome, costly, and prone to clogging, with complex equipment that is difficult to handle and control, especially when applying higher pressures, which limits their suitability for efficient and controlled adhesive application in manufacturing processes.

Innovation Solution

A partly disposable plug&spray system using two disposable containers for the adhesive components, capable of withstanding pressures between 10 kPa and 1000 kPa, with a lightweight, adaptable design that includes a flexible inner vessel and a robust outer wall for easy relocation and precise control of adhesive application, utilizing pressurized air and a coupler for efficient mixing and application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If prior art systems use large containers with pressure equipment for adhesive application, then adhesive can be supplied continuously, but the equipment becomes voluminous, complex and costly

Engineering Contradiction:
Improvecontinuous adhesive supplyVSAvoidequipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the adhesive supply into two separate disposable containers (first component and second component), each independently manageable. This segmentation eliminates the need for complex pumping systems while enabling continuous supply through simple connection to spray equipment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention employs disposable containers for adhesive components that are replaced when empty, eliminating the need for expensive, complex pressure equipment and cleaning systems. The disposable nature maintains productivity while dramatically reducing device complexity

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If pressure is applied to transfer adhesive from container to spray equipment, then adhesive flow is enabled, but clogging and blocking of tubes may occur

Engineering Contradiction:
Improveadhesive transferVSAvoidclogging risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The disposable containers are designed to be replaced rather than cleaned, eliminating clogging issues entirely. When clogging occurs, the entire container is discarded and replaced, ensuring continuous reliable operation without maintenance

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If complicated supporting equipment such as pumps and pressure devices is used, then adhesive can be pressurized and transferred, but the system becomes difficult to handle and relocate

Engineering Contradiction:
Improveadhesive application capabilityVSAvoidmobility and handling
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

By using disposable containers that can be directly connected to spray equipment, the system eliminates heavy pumps and pressure devices. The simplified setup is easily moved and reconfigured, maintaining productivity while dramatically improving mobility and ease of operation

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
