Solution Overview

Problem

Existing 3D applicators for applying sealants and insulating materials have large interfering contours due to multi-part nozzles, making it difficult to access certain areas during application.

Innovation Solution

The applicator design features direct and immediate mounting of nozzles in nozzle holders without adapters, utilizing force-fit or form-fit connections, such as screw connections, with flat contact surfaces and parallel alignment, reducing the interfering contour.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multi-part nozzles with adapters are used, then the nozzle can accommodate various plates required for function, but the interfering contour becomes large making it difficult to access certain areas

Engineering Contradiction:

Improvenozzle adaptabilityVSAvoidinterfering contour

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent extracts and eliminates the adapter component from the nozzle assembly. By designing the nozzle body with integrated mounting features that directly interface with the applicator head, the adapter is removed entirely. This reduction in components directly decreases the interfering contour while maintaining the nozzle's ability to accommodate various functional plates through its integrated design.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the adapter function into the nozzle body itself. The nozzle body is designed with integrated mounting interfaces and structural features that previously required a separate adapter component. This consolidation reduces the overall assembly size and interfering contour while preserving the adaptability to accommodate different functional plates.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multi-part nozzles with adapters are used, then the nozzle can be mechanically adapted to the interface, but the device complexity increases

Engineering Contradiction:

Improvenozzle adaptabilityVSAvoidnozzle structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the adapter component from the nozzle assembly, reducing the total number of parts. The nozzle body is redesigned with integrated mounting features that directly interface with the applicator head, eliminating the need for a separate adapter. This reduces device complexity while maintaining adaptability through the integrated design.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the adapter's functional requirements into the nozzle body design. The nozzle body incorporates mounting interfaces and structural features that previously required a separate adapter component, thereby reducing the number of components and simplifying the overall device structure while preserving adaptability.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If adapters are used to mount nozzles, then the nozzles can be mechanically adapted, but the material channel length increases reducing application quality

Engineering Contradiction:

Improvenozzle adaptabilityVSAvoidapplication quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent removes the adapter component from the material flow path. By designing the nozzle body with direct mounting to the applicator head, the material channel is shortened as it no longer needs to pass through an additional adapter component. This direct connection improves application quality by reducing material channel length while maintaining adaptability through integrated design features.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If adapters are used to mount nozzles, then the nozzles can be mechanically adapted, but the weight increases

Engineering Contradiction:

Improvenozzle adaptabilityVSAvoidnozzle assembly weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent extracts and eliminates the adapter component from the nozzle assembly. By designing the nozzle body with integrated mounting features that directly interface with the applicator head, the unnecessary weight of the adapter is removed. This weight reduction is achieved while maintaining the nozzle's adaptability through its integrated design.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the adapter's structural requirements into the nozzle body, eliminating the need for a separate adapter component. This consolidation reduces the total weight of the nozzle assembly while preserving the adaptability to accommodate various functional plates through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An applicator for applying an application agent (e.g. sealant, insulating material) to a component (e.g. motor vehicle body component). The applicator having a mounting flange, in particular for mounting the applicator on an application robot, a plurality of nozzles for emitting a respective jet of the application agent onto the component, wherein the nozzles are each designed as a separate component, and an applicator head at the distal end of the applicator, wherein the applicator head includes a respective nozzle holder for mounting the individual nozzles. The individual nozzles are each mounted directly in the associated nozzle holders of the applicator head.
