Solution Overview

Problem

Existing differential pressure sensor devices are limited in their ability to connect with a variety of hose types due to specific geometrical requirements, restricting the use of hoses with different material thicknesses.

Innovation Solution

A differential pressure sensor package equipped with an adaptor device featuring a base body with receptions for coupling nozzles and connecting nipples, which increases the distance between the nozzle connections, allowing for the use of hoses with thicker material by extending the distance between the muzzle openings, enabling a wider range of hose types to be compatible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the distance between coupling nozzles is reduced to accommodate thinner hoses, then the device can use thinner hoses with smaller cross-sections, but the device cannot accommodate hoses with thicker material

Engineering Contradiction:
Improvecompatibility with different hose typesVSAvoiddistance between coupling nozzles
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent introduces an adaptor device as an intermediary component between the coupling nozzles and the hoses. This adaptor includes a body with receiving portions that accept the coupling nozzles and connecting portions that interface with hoses. By positioning the receiving portions closer together than the connecting portions, the adaptor mediates between the fixed nozzle spacing and the variable hose thickness requirements, enabling compatibility with both thin and thick hoses without modifying the original coupling nozzle arrangement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a specific hose type with predetermined thickness is used, then connectivity is ensured for a given device geometry, but the device cannot connect to hoses with different material thicknesses

Engineering Contradiction:
Improveconnectivity assuranceVSAvoidrange of compatible hose types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The adaptor device is designed with universal compatibility features that enable it to work with multiple hose types having different wall thicknesses. The receiving portions are configured to accommodate various coupling nozzle geometries, while the connecting portions provide standardized interfaces for different hose outer diameters. This multi-functional design allows a single adaptor to ensure reliable connectivity across a range of hose specifications, eliminating the need for device-specific hose selections.

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