Solution Overview

Problem

Existing connections between gas pressure meters and heating devices are difficult to establish when the gas nipple is located close to walls or other components of the heating device, requiring significant force and making it challenging to achieve a reliable connection.

Innovation Solution

A connector with an elongated flexible member and a rigid support, where the rigid member extends less than half the circumference of the elongated member, allowing for axial force application from a distance without buckling, and featuring a through channel for fluid connection, enabling the connector to reach and connect to the gas nipple even in confined spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flexible tube is used to connect the gas nipple to the gas pressure meter, then the connection can accommodate movement and misalignment, but the tube requires considerable axial force to establish a reliable connection, making it difficult to attach when the gas nipple is close to walls or other components

Engineering Contradiction:
Improveconnection flexibilityVSAvoidattachment difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connector is divided into two distinct segments: a flexible elongated member for connecting to the gas nipple and a rigid member for force application. This segmentation allows each part to perform its specific function optimally - the flexible part provides adaptability while the rigid part enables easy attachment from a distance

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rigid member acts as an intermediary that transfers axial force from a distance to the flexible elongated member. This mediator enables the user to apply the necessary force to establish a reliable connection without needing to be in direct contact with the gas nipple, solving the attachment difficulty in confined spaces

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the user applies force directly to the flexible tube near the gas nipple to establish a reliable connection, then the connection withholds gas pressure, but the user needs direct access to the gas nipple which is difficult when it is close to walls or other components

Engineering Contradiction:
Improveconnection reliabilityVSAvoidaccessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The rigid member extends in the longitudinal direction over a length that at least corresponds to the nipple connector length, allowing force application from a distance along the longitudinal dimension. This dimensional extension enables the user to reach and apply force at a more accessible location rather than requiring direct access to the gas nipple position

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If a rigid member is added to support the flexible tube for force application from a distance, then the connector can be attached from a distance without buckling, but the connector may become too large to fit in confined spaces

Engineering Contradiction:
Improveforce application distanceVSAvoidconnector cross-sectional dimensions
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The rigid member extends in the circumferential direction over less than half the circumference of the elongated member, providing rigidity only where needed for force application while maintaining flexibility and small cross-sectional dimensions in other areas to fit confined spaces

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The rigid member is positioned asymmetrically on the elongated member, extending over less than half the circumference. This asymmetric configuration provides the necessary structural support for force application while minimizing the overall cross-sectional dimensions to accommodate confined installation spaces

Inventive Principle:
Principle #4Asymmetry
