Solution Overview

Problem

Sprayers often cannot connect to different fluid or air sources due to incompatible couplings, limiting the ability to use newer or more affordable sources.

Innovation Solution

A self-tapping adapter with first and second connectors, each equipped with self-tapping portions, allows coupling to sprayers and fluid sources with different connection types, including non-threaded and soft materials, creating a secure seal and facilitating the use of various sprayer and fluid sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a sprayer uses a fixed connector type, then the connection is reliable and secure, but the adaptability to different fluid or air sources is limited

Engineering Contradiction:
Improveadaptability to different fluid or air sourcesVSAvoidconnector compatibility requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter incorporates multiple connector types (first connector for fluid sources, second connector for air sources) within a single device, enabling it to universally connect to different sprayer and source combinations. This multi-functional design allows one adapter to replace multiple specialized connectors.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adapter acts as an intermediary component between the sprayer and the fluid/air sources. It mediates the connection by providing self-tapping portions that can attach to various source types, thereby enabling compatibility without modifying the sprayer itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the adapter uses self-tapping portions, then the ease of operation and tool-free installation is improved, but the reliability of the connection may be compromised compared to threaded connections

Engineering Contradiction:
Improvetool-free installationVSAvoidconnection security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The self-tapping portions are designed to automatically create threaded holes and form secure connections without requiring external tools or pre-drilled holes. The adapter serves itself by combining the drilling and threading functions in a single self-contained component that attaches directly to the sprayer and sources.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The self-tapping portions utilize material property changes during installation, where the tapping action deforms and displaces material to create secure mechanical interlocking. This parameter change from undeformed to deformed state provides reliable connection without traditional threading.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the adapter is designed to work with soft materials, then the adaptability to various connector types is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvecompatibility with soft material connectorsVSAvoidtapping hole alignment and seal formation
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The adapter features localized quality variations in its self-tapping portions, with specific geometric configurations optimized for engaging soft materials. The tapping holes and sealing surfaces have precise local dimensions and tolerances tailored for material deformation and seal formation, while other parts of the adapter maintain standard manufacturing tolerances.

Inventive Principle:
Principle #3Local quality
