Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray gun and painting-agent conducting device assemblies face challenges in achieving stable engagement and easy detachment while minimizing material usage and ensuring firm retention in all degrees of freedom.
Innovation Solution
The use of mechanical guides, such as oblique guide surfaces, rails, channels, and mandrels, facilitates the alignment and secure attachment of the painting-agent conducting device on the spray gun, allowing for easy engagement and disengagement by guiding the device along a defined path and preventing deviation, thereby minimizing the need for complex designs or expensive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complicated design with more material is used, then stability is improved, but device complexity and material usage increase
Solution Approach 1:
The patent employs conical guide surfaces that merge together to center the painting-agent conducting device. The conical geometry provides self-centering action through its curved surface, guiding the device along a predefined path to the stop on the spray gun body. This curved surface approach achieves stable positioning without requiring complex mechanical structures or additional retention components.
2Reliability
If a complicated design with more material is used, then stability is improved, but material usage increases
Solution Approach 1:
The conical guide surfaces utilize geometric curvature to provide centering and guiding functions. The merging conical surfaces create a self-centering mechanism that reduces the need for additional retaining materials or complex structural components, achieving stable engagement with minimal material consumption.
3Manufacturing precision
If guide surfaces are arranged obliquely to the application direction, then centering is improved, but the path length increases
Solution Approach 1:
The conical guide surfaces are arranged to merge together, creating a funnel-like structure that provides oblique centering action. The conical geometry naturally guides the painting-agent conducting device along a curved path to the center position, achieving precise centering while managing the insertion path length through its geometric configuration.
4Manufacturing precision
If a mechanical guide with conical surfaces is used, then centering and positioning are improved, but device complexity increases
Solution Approach 1:
The conical guide surfaces are merged together to form an integrated guiding structure. This merging of surfaces creates a unified mechanical guide that provides both centering and positioning functions simultaneously, reducing the need for separate guiding components and simplifying the overall device structure while maintaining positioning precision.

AI summary
A painting-agent conducting device (1) is releasably engageable with a spray gun (11). Mechanical guide (7) arrangements assure that the device is properly guided into the operative position in engagement with the spray gun body (21). In the operative position the painting-agent conducting device is stably held in engagement with the spray gun and is prevented from undesirable movement relative thereto. The painting-agent conducting device is manually disengageable from the spray gun when desired for cleaning and/or replacement.
