Solution Overview
Problem
Existing refilling devices for hydronic heating systems lack automation, requiring manual operation and lacking sensors for precise control of water treatment and refilling processes, which can lead to inefficiencies and potential system malfunctions.
Innovation Solution
A monolithic refilling device with integrated sensors (conductivity/TDS, temperature, pressure, and flow meters) and a controller that automates the operation by connecting to a water supply system, allowing for automatic control of shut-off valves, softening/demineralization cartridge management, and leakage detection, ensuring efficient and safe refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a monolithic housing with integrated sensors and automated control is implemented, then automation and control precision are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple previously separate components (refilling device, heatwater treatment unit, sensors, controller) into a single monolithic housing. This integration merges the functions of manual shut-off valves, backflow preventers, pressure reducing valves, softening/demineralization cartridges, and automated control systems into one unified device, thereby improving automation while managing complexity through functional consolidation.
Solution Approach 2:
The monolithic housing serves multiple functions simultaneously: it houses refilling operations, water treatment (softening/demineralization), sensor integration (conductivity/TDS, temperature, pressure, flow), automated control, and leakage detection. This multi-functionality allows a single device to perform what previously required multiple separate units, improving automation without proportionally increasing complexity.
2Measurement precision
If multiple sensors and automated control systems are integrated, then measurement precision and control accuracy are improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where multiple sensors (conductivity/TDS, temperature, pressure, flow) continuously monitor system parameters and provide data to a controller. The controller automatically adjusts operations based on this feedback, enabling precise measurement and control of water treatment processes, refilling operations, and leakage detection. This feedback mechanism improves measurement precision while managing complexity through automated decision-making algorithms.
3Ease of operation
If manual operation is replaced with automated control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent enables the refilling device to operate autonomously through self-service automation. The integrated controller automatically manages shut-off valve operations, monitors water quality parameters, controls softening/demineralization processes, detects leaks, and manages cartridge replacement without requiring manual intervention. This self-service capability dramatically improves ease of operation while the monolithic integration keeps complexity manageable through unified system architecture.
