Solution Overview

Problem

Current refrigerant recovery systems lack effective management processes, leading to inefficiencies and environmental concerns such as ozone destruction and global warming.

Innovation Solution

A refrigerant recovery management system comprising a recovery server, treatment server, and management server that generate and transmit request and report data to manage refrigerant recovery, treatment, and allocation of considerations to practitioners, ensuring conformity and efficient refrigerant handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If refrigerant recovery is performed without management system, then refrigerant can be recovered from equipment, but recovery process cannot be tracked and verified leading to environmental harm

Engineering Contradiction:

Improverefrigerant recovery managementVSAvoidmanagement system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The management system is segmented into three distinct server components: recovery server for managing recovery practitioners and processes, treatment server for managing treatment practitioners and processes, and management server for overall supervision and consideration allocation. This segmentation allows each server to handle specific functions independently, making the overall system manageable despite its complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The management server acts as an intermediary between the recovery server and treatment server, coordinating their operations, verifying data conformity, and allocating considerations. This intermediary role ensures reliable management by centralizing control while allowing specialized functions to remain distributed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If detailed tracking information is collected for refrigerant recovery and treatment, then conformity can be verified and considerations allocated accurately, but information management complexity increases

Engineering Contradiction:

Improverefrigerant tracking accuracyVSAvoiddata management burden

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where the management server receives data from both recovery and treatment servers, verifies conformity between them, and uses this feedback to allocate considerations accurately. The conformity verification process ensures that treatment data matches recovery data, providing precise tracking while maintaining data integrity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The management server merges and consolidates data from multiple sources (recovery server and treatment server) into a unified management framework. This merging allows comprehensive tracking of refrigerant flow while centralizing information management, reducing the burden on individual servers and ensuring consistent data verification.

Inventive Principle:

Principle #5Merging (Combining)

3Manufacturing precision

If conformity verification between recovery and treatment data is implemented, then accurate consideration allocation is achieved, but processing time increases

Engineering Contradiction:

Improveconsideration allocation accuracyVSAvoiddata verification time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary data verification by the management server before proceeding to consideration allocation. By checking conformity between recovery and treatment data in advance, the system ensures accurate allocation decisions are made based on verified information, preventing errors that would require time-consuming corrections later.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The manual or mechanical process of verifying data conformity is replaced with automated server-based verification. The management server automatically compares data from recovery and treatment servers, using electronic data processing to rapidly verify conformity without manual intervention, thus reducing verification time while maintaining accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A refrigerant recovery management system includes a first generation unit and a second generation unit. The first generation unit generates first information to send a refrigerant recovered from refrigerant-use equipment to a refrigerant treatment practitioner that conducts refrigerant treatment on the refrigerant. The second generation unit generates second information on the refrigerant treatment, to report the refrigerant treatment to a manager that manages refrigerant recovery.
