Solution Overview

Problem

Existing compressor systems lack effective monitoring of multiple parameters, particularly in compressor performance and filter condition, leading to inefficiencies and economic losses due to inadequate detection of pressure drops and filter contamination.

Innovation Solution

A system comprising a compressor, a filter, and a multiple indicator gauge that simultaneously displays differential pressure and economic parameters related to compressor operation, using a unitary movable indicator to show the pressure drop across the filter and its impact on system efficiency, allowing for timely filter maintenance and optimization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single indicator gauge is used to monitor compressor parameters, then the device complexity is reduced, but the measurement precision and information completeness deteriorate due to inability to display multiple parameters simultaneously

Engineering Contradiction:
Improvegauge structureVSAvoidparameter monitoring accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The single gauge indicator is segmented into multiple functional zones: a first indicator portion for differential pressure measurement and a second indicator portion for economic parameter measurement. This segmentation allows the gauge to display multiple parameters simultaneously while maintaining a unified compact structure, resolving the contradiction between device simplicity and measurement comprehensiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gauge is designed with multi-functionality to monitor both differential pressure across the filter and economic parameters (operating costs, efficiency) within the same device. This universal approach eliminates the need for separate gauges for each parameter, reducing overall system complexity while providing comprehensive monitoring capabilities.

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

2Measurement precision

If multiple separate gauges are used to monitor different parameters, then the measurement precision for each parameter is improved, but the device complexity and space requirements increase

Engineering Contradiction:
Improveparameter monitoring accuracyVSAvoidgauge system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple gauge functions are merged into a single integrated indicator system. The first and second indicator portions are combined on one gauge face, allowing simultaneous display of differential pressure and economic parameters. This merging reduces the number of separate devices needed while maintaining accurate measurement capabilities for each parameter.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gauge achieves universality by incorporating multiple measurement and display functions within a single device. It simultaneously provides differential pressure monitoring and economic parameter indication, eliminating the need for multiple separate gauges and reducing system complexity.

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

3Productivity

If real-time monitoring of multiple parameters is implemented, then the productivity and system efficiency are improved, but the device complexity and cost increase

Engineering Contradiction:
Improvesystem efficiencyVSAvoidmonitoring system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The indicator is segmented into distinct functional portions that can be independently calibrated and maintained. The first portion monitors differential pressure for filter condition assessment, while the second portion displays economic parameters. This segmentation enables targeted maintenance and reduces overall system complexity while providing comprehensive real-time monitoring.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gauge provides self-service by integrating both measurement and display functions in a single unit that requires minimal external infrastructure. The economic parameter indication is derived directly from the differential pressure measurement, eliminating the need for separate sensors or complex calculation systems.

Inventive Principle:
Principle #25Self-service

AI summary

A compressor in fluid communication with a filter is disclosed. A gauge is used with the filter and is configured to react to a pressure drop across the filter and indicate an increasing amount of contaminants captured by the filter. The gauge is provided with a dial having multiple scales thereon. A unitary indicator, such as a needle, is further provided with multiple indicating portions which can be used to indicate a property of the fluid, such as a differential pressure across the filter, and can simultaneously indicate a property, such as an economic cost associated with running the compressor with a filter having accumulated contaminants.
