Compact Spray Applicator Nozzle Arrangement for Narrow Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray applicators are too bulky to fit into narrow spaces, such as the interior of a motor vehicle's door sill, making it impossible to form a continuous layer without gaps when applying material to adjacent nozzle bodies.
Innovation Solution
A compact spray applicator design with a carrier body and nozzle bodies arranged such that their center planes cross along a straight line extending outside the carrier body, allowing for closely spaced nozzle bodies with overlapping spray jets to apply material in a distributed manner over a large angular range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional spray applicators are used, then they can apply material to surfaces, but they are too bulky to fit into narrow spaces such as the interior of a motor vehicle's door sill
Solution Approach 1:
The spray applicator is divided into multiple nozzle bodies (at least two) that can be selectively activated. Each nozzle body has its own spray slit and can be independently controlled, allowing the applicator to be compact while still covering the required area through coordinated operation of multiple segments
Solution Approach 2:
The nozzle bodies are arranged with their center planes crossing along a straight line that extends outside the carrier body, with contact surfaces offset in the direction of the straight line. This spatial arrangement allows compact positioning while maintaining spray coverage in narrow spaces
2Manufacturing precision
If multiple nozzle bodies are positioned closely together, then a continuous layer can be formed without gaps, but the structure becomes more complex
Solution Approach 1:
Multiple nozzle bodies are mounted on a common carrier body with shared contact surfaces that face the straight line. The nozzle bodies are positioned and oriented such that their spray jets overlap to form a continuous layer, merging their functions into a coordinated system that achieves continuity without excessive complexity
Solution Approach 2:
The carrier body provides universal mounting for multiple nozzle bodies through standardized contact surfaces. The same carrier body structure supports different nozzle configurations, and the nozzle bodies themselves can be identical or different, providing multi-functionality while maintaining a relatively simple overall structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the formation of a continuous, sharply delimited layer without gaps, even in narrow spaces, by allowing the nozzle bodies to be positioned closely together and maintaining a compact structure for efficient production and maintenance.
Implementation Method 1
a spray slit for producing a spray jet fanned out transversely to a center plane

AI summary
A spray applicator is disclosed. The spray applicator can include a carrier body including a number of contact surfaces and at least two nozzle bodies. Each nozzle body can be fastened on one of the contact surfaces and have a spray slit for producing a spray jet fanned out transversely to a center plane. the center planes can cross one another along a straight line. The straight line can extend outside the carrier body. The contact surfaces can face the straight line and be offset with respect to one another in the direction of the straight line.
