Solution Overview

Problem

Existing tools lack the precision and control to apply a consistent, controlled amount of fluid to work pieces, leading to messy applications in model building and other precision-driven endeavors.

Innovation Solution

A fluid applicator with a loop and neck design, featuring a rim with a quadrilateral cross-section and an obovate aperture, allowing for precise fluid transfer to work surfaces, and a method involving dipping the applicator loop in fluid and applying it to the surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If prior tools (glass rods, fine paintbrushes, small aluminum tubes) are used to apply fluid, then the device complexity is low, but the manufacturing precision and control of fluid application are insufficient

Engineering Contradiction:

Improveprecision and control of fluid applicationVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The applicator is divided into distinct functional segments: a base portion for fluid reservoir, a neck portion for fluid transfer, and a loop portion for precise application. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The loop portion features a controlled aperture with specific dimensional parameters (opening size, rim thickness) that are optimized to control fluid flow rate and application precision. The neck portion has tapered dimensions that control fluid transfer characteristics

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If a loop with aperture and rim structure is used, then the precision of fluid application is improved, but the ease of manufacture decreases

Engineering Contradiction:

Improveprecision of fluid applicationVSAvoidease of manufacture

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The base, neck, and loop portions are formed as a single integrated structure from one piece of material. This merging eliminates the need for assembly of multiple components while maintaining the precise geometric features required for controlled fluid application

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single-piece construction serves multiple functions: the base acts as both structural support and fluid reservoir, the neck serves as both connector and fluid transfer channel, and the loop provides both structural integrity and precise application interface

Inventive Principle:

Principle #6Universality (Multi-functionality)
