Paint Spray Gun Flow Reservoir Screw-Wedge Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flow reservoirs for paint spray guns are complex and costly to manufacture, requiring separate attachment parts and additional adapters for attachment to the gun, complicating the process and increasing expenses.
Innovation Solution
A flow reservoir designed with a two-part structure, featuring a screw-wedge element on the cover for easy and quick attachment to the paint spray gun without additional adapters, and an optional external thread for compatibility with conventional internal threads, allowing for easy filling and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate attachment parts are manufactured and connected to the container, then the flow reservoir can be detachably fastened to the paint spray gun, but the manufacturing process becomes complicated and costs increase
Solution Approach 1:
The attachment part is merged with the cover to form an integrated component. The cover (2) includes the attachment part (3) as a unified structure, eliminating the need for separate manufacturing and assembly of attachment parts. This integration simplifies the manufacturing process while maintaining the detachable fastening capability to the paint spray gun.
2Reliability
If a hollow cylindrical attachment part is used on the cover, then the container can be closed securely, but an additional adapter is required for attachment to the paint spray gun
Solution Approach 1:
The attachment part (3) is designed with multi-functionality: it serves both as the closure element for the container and as the direct attachment interface for the paint spray gun. The hollow cylindrical structure provides both the sealing function and the mounting interface, eliminating the need for separate adapters and reducing overall system complexity.
3Reliability
If conventional separate attachment parts are used, then detachable fastening is achieved, but quick attachment and removal without additional adapters is not possible
Solution Approach 1:
The attachment part (3) is pre-integrated into the cover (2) during manufacturing, with the quick-connect mechanism already in place. This preliminary integration allows the flow reservoir to be attached directly to the paint spray gun without requiring additional adapters or complex assembly steps, enabling quick attachment and removal while maintaining secure fastening.
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
The solution enables economical production and easy attachment/removal of the flow reservoir, facilitating its use as a one-time, reusable, or storage container, while ensuring secure and efficient paint management.
Implementation Method 1
The screw-wedge element (8) can be configured as a wedge-shaped or screw-shaped projection, which is led into engagement with a corresponding groove on the paint spray gun
Implementation Method 2
The screw-wedge element (8) can be configured as a wedge-shaped or screw-shaped projection

AI summary
The invention relates to a flow reservoir for a paint spray gun with a bowl-shaped container (1), a cover (2) that can be set on the container (1), and an attachment part (3) for direct fixing of the flow reservoir to the paint spray gun. The flow reservoir is distinguished in that the attachment part (3) consists of a connector (5) formed directly on the cover (2) with a screw-wedge element (8) for direct quick-connect attachment of the flow reservoir to the paint spray gun.
