Solution Overview

Problem

Existing hose assemblies face issues with joint detachment due to increased length and diameter caused by flux and hydraulic pressure, as the non-elastic sleeve and elastic hose materials create a mismatch in expansion, leading to unreliable connections with faucets or sprinklers.

Innovation Solution

A joint assembly featuring an internal joint with an external thread and annular ridge, and an external joint with a conical internal face, where the shank of the internal joint is inserted into the hose and the external joint's shank is inserted into the sleeve, ensuring secure engagement through threaded connections and elastic hooks to maintain attachment under pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hose is made of elastic material to allow flexibility, then the hose can expand under flux and hydraulic pressure, but the joint assembly may detach from the hose assembly due to the mismatch in expansion between the elastic hose and non-elastic sleeve

Engineering Contradiction:
Improvehose expansion capabilityVSAvoidjoint connection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The joint assembly employs a nested structure where the internal joint is inserted into the hose, which is then inserted into the sleeve, which is then inserted into the external joint. This nested arrangement allows each component to accommodate the expansion of the elastic hose while maintaining secure connections, resolving the contradiction between hose expandability and joint reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The joint assembly is divided into separate internal and external joint components that can independently accommodate hose expansion. The internal joint engages with the hose internally while the external joint engages with the sleeve externally, allowing segmented response to expansion forces and preventing detachment.

Inventive Principle:
Principle #1Segmentation

2Strength

If the sleeve is made of non-elastic material to maintain structural integrity, then the sleeve provides stable support, but it cannot accommodate the longitudinal extension of the hose under pressure

Engineering Contradiction:
Improvesleeve structural integrityVSAvoidsleeve extension capability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The joint assembly applies local quality by creating localized engagement zones at the ends of the hose assembly where the joints are positioned. The rigid sleeve maintains its structural integrity in the main body while the joint assemblies at the ends provide localized adaptability to accommodate hose expansion and contraction.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system segments the functional requirements by allowing the sleeve to maintain rigidity for structural support while the joint assemblies provide the necessary flexibility and expansion accommodation at the connection points, resolving the contradiction between overall structural integrity and local extension capability.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the joint assembly uses a simple connection structure, then the assembly is easy to manufacture, but it cannot withstand the increasing length and diameter of the hose assembly under hydraulic pressure

Engineering Contradiction:
Improvejoint assembly simplicityVSAvoidjoint connection strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The nested joint structure provides multi-level engagement between components, creating redundant connection points that strengthen the overall assembly without requiring complex manufacturing processes. Each nested level contributes to the cumulative strength needed to withstand hydraulic pressure while maintaining relative manufacturing simplicity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The joint assembly utilizes composite construction combining rigid joint components with the flexible hose and sleeve materials, creating a composite structure that leverages the strengths of each material type to achieve both manufacturing feasibility and pressure resistance.

Inventive Principle:
Principle #40Composite materials
