Top-Mounted Spray Gun Control for Ambidextrous Pattern Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray guns with side or rear control knobs are difficult for left-handed users and awkward for both right and left-handed users due to their configuration, posing challenges in retail environments like tanning salons.
Innovation Solution
A spray gun with a top-mounted control knob and a main airflow channel divided into two flow openings, allowing for easy adjustment of the spray pattern by a top knob controller, suitable for both left and right-handed users, and featuring a flexible needle assembly for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If side control knobs are used on spray guns, then the design is suitable for right-handed users, but it becomes difficult for left-handed users to operate
Solution Approach 1:
The control knobs are repositioned from the side to the top of the spray gun handle, creating a universal design that allows both right-handed and left-handed users to easily access and operate the controls. This positional change makes the device adaptable to different user preferences and handedness without requiring separate designs.
2Device complexity
If rear control knobs are positioned close to each other, then the structure is compact, but the controls become awkward to use
Solution Approach 1:
The controls are moved from a horizontal arrangement on the side or rear to a vertical arrangement on the top of the handle. This dimensional change allows the knobs to be spaced further apart in the vertical direction, improving accessibility and ease of operation while maintaining a compact overall structure.
3Device complexity
If control knobs are positioned on the side or rear of the spray gun, then the design is simple, but it creates difficulty for left-handed users in retail environments
Solution Approach 1:
The control knobs are positioned asymmetrically on the top of the handle rather than on the side or rear, creating a design that naturally accommodates both right-handed and left-handed users. This asymmetric top-mounted positioning eliminates the handedness bias inherent in side-controlled designs.
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 top-mounted control design provides ergonomic access for both handedness types, enhancing user comfort and ease of use, while the flexible needle assembly accommodates movement and flexibility, improving operational efficiency.
Implementation Method 1
The valve may include a wedge-shaped stopper protruding and extending therefrom. The wedge-shaped stopper may have a protruding point adapted to be positioned in registration with an arc-shaped guide groove formed at a bottom of the control seat of the gun body.

AI summary
A spray gun for use in association with a fluid container includes a gun body, a gun head, a main airflow channel and a top knob controller. The gun body has a control seat formed therein on a top portion of the gun body. The gun head is operably attached to the front of the gun body. The main airflow channel is in the gun body and divided into a fist flow opening and a second flow opening at a base of the control seat. It is operably connected to the gun head. The top knob controller is operably connected to the control seat whereby adjusting it controls the air flow into the first flow opening and the second flow opening thereby controlling the spray pattern. A needle body assembly includes a needle body; a needle handle; and a needle sleeve operably connecting the needle body to the needle handle.
