Solution Overview

Problem

Existing faucets face challenges in assembly and fastening, particularly during installation on countertops, where parts are subject to wear and tear, and require simple manipulation with minimal components to maintain functionality.

Innovation Solution

A faucet design featuring a fluid distribution assembly with interlocking conduits and a housing that uses nipples with rims for retention, allowing for easy assembly and secure mounting without additional fixation means, utilizing a combination of longitudinal and transverse retention mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate fasteners and fixation means are used to assemble conduit components, then the connection strength and reliability are improved, but the device complexity and number of parts increase

Engineering Contradiction:
Improveconnection strengthVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple fastening functions into a single integrated nipple component. The nipple includes an interlocking portion for mechanical engagement and a retention portion that works with a retention feature to secure the conduit assembly, eliminating the need for separate fasteners and reducing part count while maintaining connection reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The nipple serves multiple functions simultaneously: it provides structural support, enables interlocking connection between components, and works with the retention feature to prevent disassembly. This multi-functional design replaces what would traditionally require multiple specialized components.

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

2Ease of operation

If traditional faucet assembly methods are used, then the structural integrity is maintained, but the ease of assembly and manipulation during installation is reduced

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The faucet assembly is divided into modular components (conduits, nipple, retention feature) that can be assembled independently and then connected. This segmentation allows for easier handling and assembly while the interlocking and retention mechanisms ensure structural integrity is maintained upon connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interlocking portion and retention feature are designed to automatically secure components together through their geometric configuration, reducing the need for additional fastening operations or complex assembly procedures while ensuring reliable structural connection.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If simple retention mechanisms are used for conduit assembly, then the ease of manufacture and assembly is improved, but the durability and resistance to wear and tear is reduced

Engineering Contradiction:
Improveease of assemblyVSAvoiddurability
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The nipple and retention feature are designed as integrated components that combine different geometric features (interlocking portions, retention portions, engagement features) to achieve both ease of assembly and high durability. The composite structural design allows simple manufacturing while ensuring resistance to wear and tear through the interlocking and retention mechanisms.

Inventive Principle:
Principle #40Composite materials
