Solution Overview

Problem

Current combined district heating and cooling systems face inefficiencies in system maintenance and control due to the lack of a reliable method to verify the physical connection of thermal devices to the specific systems, leading to potential errors and increased man-hours and costs in troubleshooting.

Innovation Solution

A method and server system that verify the physical connection of thermal devices to a combined district heating and cooling system by comparing sensor-measured data from verified devices with unverified devices, using criteria such as fluid pressure, temperature, and geographic location to determine accurate connections, thereby reducing local measurements and enhancing control efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual verification methods are used to confirm thermal device connections, then connection accuracy can be ensured, but time consumption and costs increase significantly

Engineering Contradiction:
Improveconnection verification accuracyVSAvoidverification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual verification methods with an automated electronic verification system that uses sensors to measure physical characteristics (temperature, pressure, flow rate) and compares them against reference data from the specific combined district heating and cooling system, thereby eliminating time-consuming manual verification while maintaining connection accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The verification system enables thermal devices to automatically verify their own connections by having them send test data about their connected system's physical characteristics to the central control function, which then autonomously compares this data with reference data to determine connection accuracy without requiring external manual verification

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple combined district heating and cooling systems operate in the same geographical area, then system coverage and service area expand, but the risk of control errors and misattribution increases

Engineering Contradiction:
Improvesystem coverageVSAvoidcontrol accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where thermal devices send test data about the physical characteristics of their connected system back to the central control function, which then compares this feedback data with reference data specific to each combined district heating and cooling system to automatically verify correct connection and prevent misattribution control errors

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary verification by comparing test data from thermal devices with pre-stored reference data about physical characteristics of each combined district heating and cooling system before control operations begin, ensuring correct system attribution and preventing control errors from the outset

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If extensive local measurements and verifications are performed, then connection accuracy is ensured, but operational complexity and costs increase

Engineering Contradiction:
Improveconnection verification precisionVSAvoidverification system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the complex verification process from the local level and centralizes it at the control function, where the central system collects test data from thermal devices and performs all comparison operations with reference data, thereby simplifying the local device complexity while maintaining measurement precision through centralized processing

Inventive Principle:
Principle #2Taking out (Extraction)
