Solution Overview

Problem

Current methods for applying adhesive on large surfaces, such as flat roofs, are labor-intensive and result in inconsistent spray patterns and increased manhours due to multiple workers spraying individually, leading to inefficiencies and potential gaps in coverage.

Innovation Solution

A self-contained application system with a movable frame, pressurized carrier source, and multiple nozzles that use a pressurized carrier to apply a uniform mixture of adhesive and air over the surface, minimizing overspray and requiring fewer operators to achieve consistent coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple roofers spray adhesive individually, then coverage area can be increased, but spray pattern consistency and coverage uniformity deteriorate

Engineering Contradiction:

Improvecoverage areaVSAvoidspray pattern consistency

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system divides the adhesive application function into multiple nozzles arranged in a linear pattern, each nozzle responsible for a specific segment of the coverage area. This segmentation allows the system to cover large areas while maintaining consistent spray patterns through standardized nozzle positioning and spacing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system controls spray parameters (pressure, flow rate, nozzle positioning) through a centralized control mechanism that adjusts parameters dynamically to maintain consistent spray patterns across all nozzles, preventing variations in adhesive application depth and coverage.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If multiple workers are used for adhesive application, then productivity can be increased, but labor intensity and time requirements increase

Engineering Contradiction:

Improveadhesive application speedVSAvoidmanhours required

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system merges the functions of multiple roofers into a single integrated apparatus with multiple nozzles operated by one operator. This consolidation maintains high productivity through parallel adhesive application across multiple segments while reducing the number of workers required and eliminating coordination time between multiple operators.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs multiple adhesive application functions simultaneously through its multi-nozzle design, allowing a single operator to cover the same area that would require multiple workers operating individually, thereby reducing total labor time and manhours.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Area of stationary object

If adhesive is sprayed over large surfaces, then coverage area is increased, but overspray and material loss increase

Engineering Contradiction:

Improvecoverage areaVSAvoidadhesive overspray

Core Design Contradiction:

Area of stationary objectVSLoss of substance

Solution Approach 1:

The system applies adhesive locally and precisely through multiple nozzles positioned at specific distances from the surface, ensuring adhesive is deposited only where needed. This localized application approach increases coverage area while minimizing overspray by controlling the spray pattern and direction from each nozzle.

Inventive Principle:

Principle #3Local quality
