Spray Gun Pressurization Sleeve Kit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray guns require dedicated piercing for pressurization, limiting adaptability and preventing use with gravity-fed systems, especially for viscous fluids.
Innovation Solution
A kit for spray guns comprising a sleeve with fluid outlets on its radial periphery, a connector to connect the cup to the sleeve, and a ring to recover pressure, allowing pressurization without modifying the gun's body, enabling adaptation for both pressurized and gravity-fed operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a piercing is provided in the body of the gun to connect an additional pipe for pressurization, then the cup can be pressurized for viscous fluids, but the spray gun loses adaptability and cannot be used with gravity-fed systems
Solution Approach 1:
The pressurization system is segmented into a detachable kit comprising a sleeve, connector, and ring components that can be assembled and disassembled independently from the spray gun body. This allows the pressurization function to be added or removed based on operational needs without permanently modifying the gun.
Solution Approach 2:
The system transitions from a static, permanent piercing modification to a dynamic, adjustable configuration. The sleeve can be positioned at different locations on the spray gun body, and the connector can be attached or detached to switch between pressurized and gravity-fed modes of operation.
2Ease of manufacture
If the spray gun body is modified with a piercing for pressurization, then viscous fluids can be handled, but the gun body structure is permanently altered
Solution Approach 1:
The pressurization system is divided into separate components (sleeve, connector, ring) that attach to the exterior of the gun body without requiring permanent modifications. The sleeve fits over the existing gun body structure, and connections are made through external interfaces.
Solution Approach 2:
The sleeve acts as an intermediary component that provides pressurization functionality without directly modifying the gun body. It interfaces with the gun body through existing external surfaces and provides the necessary fluid connection points through its wall structure.
3Adaptability or versatility
If a dedicated pressurized spray gun is manufactured with piercing, then pressurization function is achieved, but the gun cannot be adapted for gravity-fed use
Solution Approach 1:
The spray gun is designed to perform multiple functions through a universal interface system. The same sleeve and connector components enable both pressurized operation (when attached) and gravity-fed operation (when removed), making the gun versatile for different fluid viscosity requirements.
Solution Approach 2:
The pressurization kit uses simple, easily manufactured components that can be quickly assembled and disassembled. The sleeve, connector, and ring are designed as basic mechanical parts that are inexpensive to produce and replace, facilitating frequent switching between different operational modes.
