Cold-Spray Particle Collection Attachment for Moving Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid phase particle deposition methods, such as cold spray, face challenges in efficiently collecting flying particles when the spray nozzle is in motion, leading to inefficiencies and resource wastage.
Innovation Solution
An attachment system with an engagement part and opening part connected to a collection section, including a guide member, is integrated with the spray nozzle to collect and guide particles not involved in film formation on the base material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a suction cylinder is used to collect flying powder after aerosol collision with base material, then powder collection is achieved, but the spray nozzle cannot be in motion and collection efficiency drops when motion is introduced
Solution Approach 1:
The suction cylinder is integrated directly onto the spray nozzle, with the suction opening positioned at the nozzle tip. This nested configuration allows the collection system to move together with the spray nozzle, maintaining effective particle collection even during nozzle motion while keeping the overall structure compact.
Solution Approach 2:
A suction opening is introduced as an intermediary element between the spray nozzle and the collection system. This opening is positioned to directly intercept flying particles at the source, enabling effective collection regardless of nozzle motion. The suction opening acts as the mediating interface that captures particles before they can disperse.
2Loss of substance
If flying powder is not collected efficiently, then resource waste increases, but collection systems add device complexity
Solution Approach 1:
The collection system is merged with the spray nozzle by integrating the suction cylinder directly onto the nozzle body. This combination eliminates the need for separate collection apparatus, reducing overall device complexity while maintaining effective particle collection to minimize powder waste.
Solution Approach 2:
The suction function is extracted and positioned directly at the spray nozzle tip, separating the collection action from the main nozzle body. This extraction allows the suction opening to directly intercept particles at the source with minimal additional structural complexity.
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
Enhances the efficiency of collecting flying particles by up to three times, even when the spray nozzle is in motion, thereby optimizing resource utilization and production efficiency.
Implementation Method 1
a suction cylinder is not attached to the spray nozzle (see FIG. 3). Thus, the technique of Patent Literature 1 has a problem that flying powder is not collected from the suction cylinder in a case where the spray nozzle is in motion.

AI summary
Even in a case where a spray nozzle of a solid phase particle deposition device is in motion, flying solid phase particles are efficiently collected. An attachment (1) includes: an engagement part (2) to be engaged with a spray nozzle (130) of a cold spray device (1); and an opening part (3) connected to the engagement part (2) and having at least one opening (3a, 3b) to be connected to a collection section (20) that is configured to collect solid phase particles (30b) which are sprayed through the spray nozzle (130) onto a base material (170) and are not involved in formation of a film on the base material (170).
