Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing liquid spray devices for outdoor applications, such as asphalt striping, face issues with accuracy due to uneven surfaces, vibration, and inability to apply paint to non-vertical surfaces, resulting in inconsistent line widths and imperfections.

Innovation Solution

A liquid spray device with a spray gun mount aligned vertically with an axle, allowing the spray gun to be positioned at any angle and distance from the surface, reducing vertical displacement and vibration effects, and enabling application to irregular surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the spray gun is mounted on a cart frame at a location different than the cart wheels, then the spray gun can be positioned for painting, but the spray gun moves vertically with respect to the painting surface causing variations in application accuracy

Engineering Contradiction:

Improvespray gun positioningVSAvoidapplication accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The spray gun is merged with the axle assembly through the spray gun mount, creating a unified structure where the spray gun becomes an integral part of the wheel-axle system. This ensures that vertical movements of the axle are directly transmitted to the spray gun, maintaining consistent spacing between the spray gun and painting surface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The spray gun mount creates an equipotential relationship between the axle and spray gun positions, ensuring that both move together through vertical displacements. This eliminates relative vertical motion between the spray gun and painting surface that would otherwise occur with separate mounting locations.

Inventive Principle:

Principle #12Equipotentiality

2Adaptability or versatility

If the cart is pushed over uneven surfaces, then the cart can navigate the terrain, but the spray gun experiences vertical displacement causing lines to vary in width

Engineering Contradiction:

Improveterrain navigationVSAvoidline width consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If the spray gun is fixed in position, then the structure is simple, but the spray gun cannot accommodate every possible painting surface orientation

Engineering Contradiction:

Improvemount structureVSAvoidsurface orientation accommodation

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The spray gun mount incorporates dynamic adjustment capabilities, allowing the spray gun to be repositioned to different angles and orientations. This transforms the previously static mounting system into an adaptable one that can accommodate various painting surface orientations while maintaining structural simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spray gun mount is designed with universal adaptability, enabling the same mounting structure to accommodate multiple painting scenarios including horizontal surfaces, vertical surfaces, and irregular geometries. This multi-functional design eliminates the need for multiple specialized mounting systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If the spray gun is mounted away from the axle, then the spray gun can be positioned for application, but vibration causes variations and imperfections on the painting surface

Engineering Contradiction:

Improvespray gun positioningVSAvoidvibration effects

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A liquid spray device is described for applying a variety of liquids, such as paint, to a surface. In one embodiment, the liquid spray device comprises a frame, an axel mounted to the frame, two wheels, each attached to the axel at opposing ends of the axel, a spray gun mount coupled to the axel, and a spray gun mounted to the spray gun mount comprising a nozzle in substantially vertical alignment with the axel, for applying the liquid under pressure to a surface.
