Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray guns have limited reach and can be heavy, leading to tilting or rotation issues when extended, restricting coverage and causing user fatigue during applications like automobile painting.
Innovation Solution
A spray gun extension adapter with a mount and handle, featuring an adapter trigger linked to an actuator that operates the spray gun, allowing extended reach without interfering with existing hose fittings and providing a mechanical advantage to counterbalance the weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the spray gun is extended to maximum reach, then the coverage area is increased, but the spray gun tilts or rotates due to mechanical moment, causing loss of spray direction control
Solution Approach 1:
The patent introduces an extension arm as an intermediary component between the user's hand and the spray gun. This extension arm acts as a mediator that transmits control forces from the user to the spray gun while maintaining proper orientation, solving the problem of spray direction control at extended reach positions.
Solution Approach 2:
The extension arm is designed with counterbalancing features that compensate for the mechanical moment created when the spray gun is extended. This counterbalancing mechanism offsets the downward rotational force, preventing the spray gun from tilting or rotating away from the intended spray direction.
2Weight of moving object
If the spray gun is made lighter to reduce user fatigue, then the ease of operation is improved, but the structural integrity and spraying precision may be compromised
Solution Approach 1:
The extension arm is constructed using composite materials that provide an optimal balance between weight reduction and structural integrity. These composite materials maintain the necessary stiffness and strength for precise spray control while being light enough to reduce user fatigue during extended operation.
3Area of stationary object
If the spray gun is extended to reach distant areas, then the coverage area is increased, but the mechanical moment causes the spray gun to rotate, creating harmful effects
Solution Approach 1:
The extension arm incorporates preliminary anti-action mechanisms that preemptively counteract the rotational force before it can cause harmful effects. By built-in counterbalancing features, the system prevents the spray gun from rotating away from the intended direction, eliminating the harmful effect of uncontrolled rotation.
4Ease of operation
If the spray gun is designed for easy handling, then the ease of operation is improved, but the reach is limited by the user's arm extension
Solution Approach 1:
The system is segmented into distinct components: the handheld spray gun and the separate extension arm. This segmentation allows the spray gun to remain compact and easy to handle, while the extension arm provides the additional reach, combining the benefits of both easy handling and extended coverage.
Solution Approach 2:
The extension arm adds a dimensional element to the system, extending the reach in a direction perpendicular to the user's arm extension. This dimensional addition allows the user to maintain a comfortable handling position while achieving greater coverage area through the extended structure.
