Integrated Hose Adapter for Error-Proof Pressure Transmitter Assembly

Solution Overview

Problem

The traditional method of assembling individual hoses between a pressure sensor and the housing of a pressure transmitter is prone to high error rates due to the complexity of connecting positive and negative connectors correctly, leading to potential misconnections and increased assembly time.

Innovation Solution

A hose adapter comprising two adjacent elastic hoses connected between end plates, with specific configurations to ensure correct connection between pressure sensor connectors and housing measuring connectors, reducing the likelihood of misconnections and simplifying the assembly process through guiding protrusions and assembling plates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual hoses are assembled between pressure sensor and housing, then connection flexibility is improved, but connection error rate increases and assembly time increases

Engineering Contradiction:

Improveconnection flexibilityVSAvoidconnection error rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple individual hoses into a single integrated hose adapter component that contains both hoses and connectors as one piece. This merging eliminates the need to separately connect multiple hoses, thereby reducing connection errors while maintaining the flexibility to connect to different pressure sensor and housing measuring connector configurations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hose adapter serves as an intermediary component between the pressure sensor connectors and the housing measuring connectors. It integrates the hoses and connectors into a single intermediate component that simplifies the connection process, reducing the complexity and error rate of direct multi-hose assembly while preserving adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If individual hoses are assembled between pressure sensor and housing, then connection flexibility is improved, but assembly time increases

Engineering Contradiction:

Improveconnection flexibilityVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple individual hoses into a single integrated hose adapter component that contains both hoses and connectors as one piece. This merging eliminates the need to separately connect multiple hoses, thereby reducing connection errors while maintaining the flexibility to connect to different pressure sensor and housing measuring connector configurations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hoses and connectors are pre-assembled into an integrated hose adapter component before installation. This preliminary assembly of the hoses and connectors into a single unit reduces the time required during final installation, as the entire assembly can be installed as one component rather than connecting multiple separate hoses on-site.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple individual hoses are connected, then measurement capability is improved, but device complexity increases

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidassembly complexity

Core Design Contradiction:
