Paint Sprayer Flow Adjustment and Reservoir Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint sprayers lack an adequate indication of flow rate and are difficult to refill and adjust for spray pattern.
Innovation Solution
A sprayer design featuring a flow adjustment mechanism, a trigger assembly, and a fluid reservoir with a cap and neck configuration that allows for easy refilling and adjustment, along with a flow rate indicator, to provide clear flow rate indication and simplify operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spray guns are used, then the basic spraying function is provided, but the flow rate indication is inadequate and the user cannot accurately control the flow rate
Solution Approach 1:
The patent incorporates a flow rate indicator that provides visual feedback to the user about the current flow rate setting. This feedback mechanism allows users to accurately control the flow rate by adjusting the flow control valve while observing the indicator, resolving the contradiction between adequate flow rate indication and ease of flow rate control.
2Productivity
If conventional spray guns are used, then the spraying function is provided, but the refilling process is difficult and time-consuming
Solution Approach 1:
The patent divides the fluid reservoir system into separable components with a quick-connect mechanism. The reservoir can be quickly detached and reattached to the spray gun body through a simplified coupling mechanism, enabling rapid refilling without complex assembly procedures, thus improving productivity while minimizing time loss.
3Adaptability or versatility
If conventional spray guns are used, then the spraying function is provided, but the spray pattern adjustment is difficult
Solution Approach 1:
The patent incorporates an adjustable spray pattern mechanism that allows dynamic modification of the spray pattern during operation. The user can easily adjust the spray pattern by manipulating a control element that modifies the fluid flow distribution, providing adaptability without requiring complex adjustment mechanisms.

AI summary
A sprayer for spraying a fluid can include a sprayer body, a trigger assembly, a flow adjustment mechanism and a fluid reservoir. The sprayer body can include a handle portion and a nozzle portion, the nozzle portion defining a fluid outlet and including a fluid conduit in communication with the fluid outlet. The trigger assembly can be coupled to the nozzle portion and be configured to open the fluid outlet. The flow adjustment mechanism can be coupled to the trigger assembly and be configured to adjust a flow rate of the sprayer. The fluid reservoir can be coupled to the sprayer body and be in communication with the fluid outlet and fluid conduit. The fluid reservoir can include a cap and first and second necks, the first neck being coupled to the sprayer body and the cap being removably coupled to the second neck.
