Removable Liquid Distribution Member for Sprayer Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint sprayers face difficulties in cleaning the ducts channeling components due to rapid hardening of catalysts or additives when exposed to water or humidity, leading to clogged pipes and high maintenance costs, often requiring complete sprayer replacement.
Innovation Solution
A modular sprayer design with a removable liquid distribution member featuring internal threads, a restriction injector, and a conductive material like stainless steel, allowing for easy extraction and cleaning, along with an explosion-proof seal for safety, facilitates maintenance and reduces costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ducts are machined directly in the sprayer body, then the sprayer structure is integrated and compact, but cleaning becomes difficult and maintenance costs increase
Solution Approach 1:
The sprayer is divided into separate modular components: the sprayer body and the distribution member. The distribution member can be removed independently from the body, allowing access to the ducts for cleaning without disassembling the entire sprayer. This segmentation resolves the contradiction by maintaining integrated design benefits while enabling easy maintenance access.
Solution Approach 2:
The distribution member containing the ducts is extracted as a separate removable component from the sprayer body. This extraction allows the ducts to be accessed, removed, and cleaned independently, solving the problem of difficult cleaning while preserving the integrated sprayer structure during operation.
2Reliability
If catalysts or additives are used in coating liquids, then the coating gains mechanical and chemical resistance, but the ducts harden rapidly and become clogged
Solution Approach 1:
The distribution member containing the ducts is extracted as a separate removable component. This allows the ducts to be easily removed and cleaned of hardened catalyst or additive deposits without affecting the sprayer body, resolving the contradiction between using performance-enhancing additives and preventing duct clogging.
Solution Approach 2:
The distribution member can be removed, cleaned, and reused multiple times. This discarding of contaminated ducts for cleaning and recovery of the component allows continuous operation with performance-enhancing additives while maintaining duct functionality through periodic maintenance.
3Reliability
If complete sprayer replacement is performed for clogged ducts, then the sprayer is restored to full functionality, but maintenance costs increase significantly
Solution Approach 1:
The sprayer is segmented into a permanent body and a removable distribution member. When ducts become clogged, only the distribution member needs to be removed and cleaned, not the entire sprayer. This segmentation dramatically reduces maintenance costs while restoring full functionality.
Solution Approach 2:
The distribution member is designed as a disposable or easily replaceable component with lower cost than the complete sprayer. When clogged beyond cleaning, it can be replaced cheaply rather than replacing the entire expensive sprayer system, reducing maintenance costs while ensuring continuous functionality.

AI summary
The invention relates to a liquid dispensing member (3) for a sprayer for spraying a coating liquid including at least two components, that comprises chambers (328, 329) for receiving valves (28, 29) for controlling the passage of at least one component and a cleaning solvent. The dispensing member (3) is provided with means for removably attaching the same in the sprayer, which makes it easier to dismantle for cleaning or replacement.
