Solution Overview

Problem

Conventional weight assemblies for faucet hoses are difficult to assemble and disassemble, often leading to insecure fixation, hose deformation, and time-consuming processes due to fixed hole sizes, complex alignment requirements, and loose connections over time.

Innovation Solution

A weight assembly featuring a counterweight with a channel and retainer system, utilizing a resilient element and pressing member to easily fix and remove the hose, ensuring stable clamping force and preventing deformation, with the counterweight being quickly connected and disconnected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hole size is made small to securely fix the weight assembly on the hose, then the fixation security is improved, but the ease of moving the weight assembly along the hose deteriorates

Engineering Contradiction:
Improvefixation securityVSAvoidease of moving weight assembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The weight assembly is divided into two separable part pieces instead of being integrally formed. This segmentation allows the first part piece to be inserted onto the hose and the second part piece to be attached later, enabling easy movement along the hose while maintaining secure fixation through the retaining member engagement between the two part pieces.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the hole size is made large to easily move the weight assembly along the hose, then the ease of moving the weight assembly is improved, but the fixation security deteriorates

Engineering Contradiction:
Improveease of moving weight assemblyVSAvoidfixation security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The weight assembly is divided into two separable part pieces instead of being integrally formed. This segmentation allows the first part piece to be inserted onto the hose and the second part piece to be attached later, enabling easy movement along the hose while maintaining secure fixation through the retaining member engagement between the two part pieces.

Inventive Principle:

3Ease of manufacture

If the weight assembly is made as two part pieces connected by retaining member with screws, then the ease of assembly is improved, but the assembly time increases due to complex alignment and screwing process

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The first part piece is pre-formed with a groove and the second part piece is pre-formed with a corresponding structure. The retaining member is designed to engage these pre-formed features without requiring complex alignment or multiple screwing operations. The groove in the first part piece guides the retaining member into place, and the second part piece's structure automatically aligns with it, eliminating the need for time-consuming alignment and repeated screwing.

4Device complexity

If the weight assembly is integrally made in oval shape with fixed hole, then the structural simplicity is improved, but the ease of assembly and removal deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidease of assembly and removal
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The weight assembly is divided into two separable part pieces instead of being integrally formed. This segmentation allows the first part piece to be inserted onto the hose and the second part piece to be attached later, enabling easy movement along the hose while maintaining secure fixation through the retaining member engagement between the two part pieces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The weight assembly transitions from a static, fixed structure to a dynamic, separable structure. The two part pieces can be easily separated and reattached, allowing the weight assembly to be moved to different positions on the hose or removed entirely when needed, providing operational flexibility while maintaining structural integrity during use.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The weight assembly allows for easy hose fixation and removal, maintains a stable clamping force to prevent deformation, and simplifies the assembly process by using a resilient element to control the clamping force and facilitate quick connection and disconnection of the counterweight.

Implementation Method 1
