Solution Overview

Problem

Compressor systems fail to reliably prevent compressed gas with impermissible concentrations of gas components from reaching consumers, posing safety risks.

Innovation Solution

A magnetically actuatable flushing valve is connected in parallel to the bypass line, automatically opening to discharge compressed gas if the gas measuring device detects concentrations outside permissible ranges, ensuring safe disposal and rapid reset when concentrations normalize.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a gas measuring device is installed to detect gas component concentrations, then the ability to detect impermissible gas concentrations is improved, but the system complexity increases due to additional components and control mechanisms

Engineering Contradiction:
Improvegas concentration detection capabilityVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A bypass line with a pressure reducer is introduced as an intermediary component to extract a portion of the compressed gas for analysis by the gas measuring device. This mediator allows the measuring device to function without being directly in the main gas flow path, enabling concentration detection while maintaining system modularity and reducing integration complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gas measuring device and its associated control components are extracted as a separate monitoring subsystem connected via the bypass line. This extraction allows the main compressor system to continue operating independently while the extracted monitoring function provides safety oversight, reducing the complexity burden on the core compression system.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a flushing valve is added to automatically discharge impermissible gas, then the safety reliability is improved, but the device complexity increases due to additional valves and control lines

Engineering Contradiction:
Improvesafety against impermissible gas dischargeVSAvoidvalve and control structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gas measuring device continuously monitors gas component concentrations and provides real-time feedback to the control unit. When impermissible concentrations are detected, the control unit automatically actuates the flushing valve to discharge the contaminated gas. This closed-loop feedback mechanism ensures safety reliability while using simple on/off valve control rather than complex continuous modulation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system is designed to automatically detect and respond to impermissible gas conditions without requiring external intervention. The gas measuring device, control unit, and flushing valve work together as a self-service safety system that autonomously monitors, decides, and acts to protect against harmful gas discharge, improving reliability without requiring additional manual control systems.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If the flushing valve discharges compressed gas to the environment, then the harmful gas concentration is reduced, but energy loss increases due to discharge of pressurized gas

Engineering Contradiction:
Improveimpermissible gas concentration at consumerVSAvoidcompressed gas energy
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

Only a portion of the compressed gas flow is extracted through the bypass line for analysis and potential flushing. The main gas flow continues to the consumer without interruption. This extraction approach allows the system to remove only the minimal amount of gas necessary to achieve safe concentrations, rather than discharging the entire compressed gas stream, thereby reducing energy loss while still eliminating harmful concentrations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flushing action is applied locally at specific points where impermissible gas concentrations are detected, rather than globally discharging all compressed gas. The pressure reducer in the bypass line creates a localized control point that allows selective flushing of contaminated portions of the gas stream while maintaining normal operation of the main gas supply, minimizing overall energy loss.

Inventive Principle:
Principle #3Local quality

4Reliability

If the compressor is switched off when gas concentrations are impermissible, then safety is improved, but productivity decreases due to shutdown time

Engineering Contradiction:
Improvesafety protectionVSAvoidcompressor operation time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The harmful function of shutting down the entire compressor system is extracted and replaced by a localized flushing mechanism. Instead of stopping production by switching off the compressor, the system extracts and discharges only the contaminated gas portion through the bypass line and flushing valve, allowing the main compressor to continue operating and maintaining productivity while still ensuring safety.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

When impermissible gas concentrations are detected, the system discards only the contaminated gas portion through the flushing valve rather than discarding the entire compressed gas supply by shutting down. This selective discarding approach eliminates harmful gas while preserving the majority of the compressed gas supply for continued use, thereby maintaining productivity while ensuring safety.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

A compressor system is specified with a compressor whose compressed gas outlet is connected to a consumer and is connected to a gas measuring device via a bypass line via a pressure reducer. The gas measuring device records concentrations of gas components such as O2, CO, CO2, NO2, humidity (H2O), VOC. A magnetically actuated flushing valve is arranged parallel to the bypass line and is connected to the gas measuring device via a control line in such a way that it opens automatically and discharges the compressed gas if the gas measuring device detects an impermissible concentration of at least one of the gas components detected.
