Solution Overview

Problem

Conventional hose connecting devices often result in entanglement and knotting of tubal bodies during assembly, leading to water output obstruction, increased internal pressure, and risk of bursting or detachment from water supply equipment.

Innovation Solution

A hose connecting device featuring a connector with an inner locking ring and outer connector, including a lubricating member and polygonal nut-shaped sections, allowing for relative rotation and preventing entanglement by creating a gap between the positioning step and stopping ring, enabling smooth assembly and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the assembling sleeve is tightly pressed by the connector to prevent rotation during assembly, then the connector can be securely fastened, but the tubal body becomes difficult to rotate and wind, causing entanglement and knotting

Engineering Contradiction:

Improveconnector fastening securityVSAvoidtubal body rotation and winding

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connector is divided into two independent parts: the assembling sleeve (61) that secures the tubal body, and the connector body (62) that provides threading. The assembling sleeve can be tightly pressed to prevent tubal body rotation during assembly, while the connector body remains free to rotate for winding operations, resolving the contradiction between secure fastening and ease of operation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector body acts as an intermediary between the assembling sleeve and the external environment. It absorbs the rotational movements and winding operations, preventing these forces from being transmitted to the tubal body while maintaining secure connection, thus enabling both reliable fastening and easy operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the assembling sleeve is tightly pressed to prevent rotation, then connection security is improved, but the tubal body becomes entangled and knotted, increasing internal pressure and risk of bursting

Engineering Contradiction:

Improveconnection securityVSAvoidentanglement and knotting

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By separating the securing function (assembling sleeve tightly pressed on tubal body) from the operational function (connector body for rotation and winding), the invention prevents entanglement and knotting of the tubal body while maintaining secure connection, thereby eliminating the harmful effects of entanglement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention converts the potential harm of restricted rotation into a benefit by designing the connector body to be free-rotating. This allows the tubal body to rotate smoothly during operation and winding without resistance, preventing entanglement and the associated harmful effects while maintaining secure fastening

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of manufacture

If the assembly parts are integrally formed to simplify structure, then manufacturing is easier, but the inserting portion cannot rotate freely when the tubal body is rotated, causing assembly troubles

Engineering Contradiction:

Improveintegral structure fabricationVSAvoidrotation during assembly

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The connector is segmented into the assembling sleeve and connector body, allowing the connector body to rotate independently during assembly operations. This segmentation maintains the ease of manufacture through standardized components while enabling free rotation to prevent assembly troubles

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector body is designed with dynamic rotational capability during the assembly process. It can rotate freely to accommodate tubal body movements and winding operations, then becomes fixed once assembled, providing both ease of manufacture and ease of operation at different stages

Inventive Principle:

Principle #15Dynamics
