Solution Overview

Problem

Existing methods for applying binary viscous fluids with aggregates to environmental surfaces face challenges such as precise registration, effective blending, and controlled layer thickness, often requiring multiple applications and being prone to disruptions like temperature variations and rain, leading to potential failure.

Innovation Solution

A wheeled apparatus with separate storage hoppers, mixing chamber, pumps, and compressed air for atomization, allowing simultaneous application of four materials in a single stream, with adjustable ratios and formulations to ensure precise blending and controlled atomization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate applications are used to apply binary viscous fluids and aggregates, then each material can be applied separately, but the process becomes time-consuming and prone to disruption

Engineering Contradiction:
Improveapplication reliabilityVSAvoidapplication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple separate application operations into a single integrated dispensing system that simultaneously applies both binary viscous fluid components and aggregates in one continuous operation, eliminating the need for multiple separate passes and reducing exposure time to environmental disruptions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system pre-mixes the binary viscous fluid components in a mixing chamber before dispensing, ensuring proper blending is accomplished in advance while the materials are still in a workable state, thereby eliminating the need for post-application blending and reducing overall process time

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If two independent dispensing vehicles are used to apply binary fluid components, then each component can be applied independently, but precise registration and blending become difficult

Engineering Contradiction:
Improveregistration precisionVSAvoiddispensing system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the dispensing of multiple materials and the blending operation into a single integrated apparatus with a common dispensing head, ensuring precise registration is maintained while simplifying the overall system compared to coordinating multiple independent vehicles

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mixing chamber serves as an intermediary component that receives separate streams of binary fluid components and aggregates, blends them together, and delivers the mixed material through a single dispensing nozzle, thereby achieving precise registration without requiring complex coordination of multiple dispensing systems

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If separate applications are made for binary fluid and aggregates, then material selection is flexible, but control of layer thickness and atomization becomes difficult

Engineering Contradiction:
Improvematerial formulation flexibilityVSAvoidlayer thickness control
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system incorporates adjustable parameters including variable pump speeds, controllable aggregate dosing rates, and adjustable air atomization pressure, allowing dynamic optimization of layer thickness and atomization quality while maintaining flexibility in material formulation through programmable control

Inventive Principle:
Principle #15Dynamics

AI summary

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.
