Solution Overview

Problem

Adhesive application devices typically require multiple units with different nozzle types for varying application characteristics and mediums, leading to increased labor, time, and inventory needs due to the necessity of replacing adapters and modules for nozzle changes.

Innovation Solution

A fluid application device with an applicator head featuring a service block, manifold, and interchangeable nozzles, where the manifold includes a flange for proper positioning and a common interface for different nozzle configurations, allowing for quick switching between nozzle types without replacing the module or service block.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple adhesive application devices with different nozzle types are used for varying application characteristics, then application versatility is improved, but device complexity and inventory requirements increase

Engineering Contradiction:
Improveapplication versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The manifold is designed with a universal interface that can accommodate multiple nozzle configurations (contact nozzles, non-contact nozzles, different outlet patterns) through a single standardized connection system. This allows one adhesive application device to perform multiple functions that previously required separate dedicated devices for each nozzle type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system is divided into separable components: the manifold with standardized interface and the interchangeable nozzles. This segmentation allows the nozzles to be independently swapped without replacing the entire application device or the manifold, enabling quick reconfiguration for different application requirements.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If adapters and modules are replaced to switch between nozzle types, then nozzle configurability is improved, but labor time and operational complexity increase

Engineering Contradiction:
Improvenozzle configurabilityVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The manifold integrates the adapter functionality directly into its structure, combining the fluid distribution function with the nozzle interface function. This eliminates the need for separate adapter components that must be installed and configured when switching nozzle types.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold is pre-configured with a standardized interface design that anticipates various nozzle connection requirements. This preliminary design decision allows nozzles to be directly connected without requiring on-site adaptation or complex installation procedures.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If service blocks and manifolds are replaced to accommodate different nozzle types, then compatibility is improved, but production time and downtime increase

Engineering Contradiction:
Improvenozzle compatibilityVSAvoidproduction time
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The manifold serves multiple functions: it distributes adhesive fluid to various nozzle types and provides a standardized mechanical interface for nozzle attachment. This multi-functionality eliminates the need to replace the manifold when changing nozzle types, maintaining production continuity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system is designed to be dynamically reconfigurable at the nozzle level while maintaining a static, permanent manifold structure. This allows quick adaptation to different application requirements without interrupting the overall system operation or requiring lengthy reconfiguration of fixed components.

Inventive Principle:
Principle #15Dynamics
