Solution Overview

Problem

Existing control systems for water heating and/or cooling installations face high complexity, leading to reduced robustness, performance, and reliability, with increased risks of errors and energy overconsumption, and thermal discomfort.

Innovation Solution

A control system with at least two controllers, including a first controller for operation during a first time period and a second controller for a second time period, with a selection module to switch between them based on task complexity and data collection, allowing for redundancy and adaptive learning modes to optimize performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only one general controller is used to control the water heating and/or cooling installation, then the device complexity is reduced, but the reliability and robustness deteriorate due to high processing complexity and increased risk of errors

Engineering Contradiction:
Improvecontroller complexityVSAvoidcontrol system reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The control system is divided into multiple specialized controllers (first controller for basic control tasks, second controller for complex tasks requiring learning mode) instead of using a single general controller. This segmentation reduces the processing complexity of each individual controller while maintaining high overall system reliability through specialized functions and redundancy.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple controllers are used to improve reliability and reduce complexity, then the control system robustness improves, but the device complexity increases

Engineering Contradiction:
Improvecontrol system reliabilityVSAvoidcontroller architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control system dynamically selects which controller to activate based on task complexity. The selection module evaluates whether basic control tasks can be handled by the first controller or if complex tasks require the second controller in learning mode. This dynamic activation strategy maintains reliability through availability of multiple controllers while minimizing operational complexity by using only one controller for simple tasks.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a single controller processes all sensor information, then the device structure is simple, but the performance deteriorates due to high processing complexity and error risks

Engineering Contradiction:
Improvecontroller structure complexityVSAvoidcontrol response performance
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

Processing responsibilities are segmented between two controllers: the first controller handles routine sensor processing and basic control decisions, while the second controller processes complex tasks requiring learning mode and adaptive optimization. This segmentation improves control response performance by distributing processing loads appropriately while keeping the overall structure manageable through clear functional division.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If the control system uses a single controller for all tasks, then the system is easier to operate, but energy consumption increases due to errors and inefficiencies

Engineering Contradiction:
Improvesystem operation simplicityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The control system operates autonomously with the selection module automatically determining which controller to activate based on task requirements. The second controller learns from operational data and automatically optimizes control decisions without user intervention. This self-service capability maintains ease of operation while reducing energy consumption through intelligent, adaptive control decisions that prevent errors and optimize efficiency.

Inventive Principle:
Principle #25Self-service
