Reversible Turret Spray Tip Assembly for Paint Sprayer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint spray guns with reversible spray turrets lack an efficient mechanism to align multiple spray tips for spraying or cleaning, requiring manual longitudinal adjustment and lacking a straightforward method to switch between different spray patterns or clear blockages.
Innovation Solution
A reversible multiple spray tip assembly featuring a tip holder and turret with projections and cam surfaces that allow rotational and longitudinal movement, enabling easy alignment of spray tips within a fluid spray passage for either spraying or cleaning, and providing visual indicators for tip selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual longitudinal adjustment is used to align spray tips, then the device can switch between spray and clean positions, but the operation becomes complex and time-consuming
Solution Approach 1:
The turret is designed to rotate dynamically within the tip holder, allowing the spray tip to automatically transition between spray position (aligned with fluid spray passage) and clean position (aligned with cleaning passage) through rotational movement rather than manual longitudinal adjustment
Solution Approach 2:
The tip holder includes a cam surface with curved geometry that guides the spray tip along a rotational path, enabling automatic positioning in spray and clean configurations through simple rotation of the turret
2Adaptability or versatility
If multiple spray tips are arranged in the turret, then spray pattern versatility is improved, but the mechanism for aligning tips becomes more complex
Solution Approach 1:
The turret rotates to dynamically position different spray tips into alignment with the fluid spray passage, allowing multiple spray patterns to be accessed through simple rotation rather than complex multi-axis adjustment mechanisms
Solution Approach 2:
The turret is segmented into discrete positions, each containing a spray tip oriented for a specific spray pattern, allowing users to select different patterns by rotating to the appropriate segment without complex alignment procedures
3Adaptability or versatility
If the turret can be rotated to align spray tips, then cleaning capability is improved, but the structural complexity increases
Solution Approach 1:
The cam surface provides a curved guide path that automatically positions the spray tip in the clean configuration when the turret is rotated, eliminating the need for separate cleaning mechanisms or complex multi-position adjustment systems

AI summary
A reversible, multiple spray tip spray gun tip assembly includes a tip holder and a turret. In one embodiment, the tip holder has a turret opening and a fluid spray passage that is in communication with the turret opening. The turret has a barrel including a plurality of spaced apart spray tips and a handle to rotate the barrel within the turret opening. Either the tip holder or the turret includes one or more projections while the other of the tip holder or the turret includes a cam surface with which the one or more projections slideable engage such that rotating the turret relative to the tip holder causes the turret to translate relative to the tip holder and to align each of the spray tips with the fluid spray passage in a spray position and a clear position.
