Heating Filling Fitting With Switchable Cartridge and Adapter Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling fittings for heating systems are limited in their ability to easily and efficiently refill both small and large systems, as the treatment capacity of water treatment cartridges is insufficient for large systems, requiring frequent cartridge changes and lacking versatility in filling options.
Innovation Solution
A filling fitting that allows for the use of either a water treatment cartridge or an adapter with two fluid-conducting connection lines, enabling the connection of an external stationary cartridge for initial filling and make-up water, with a uniform interface for quick system changes and easy coupling via socket attachments and plug-in receptacles, and optionally using hose connection nipples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water treatment cartridge is used for filling heating systems, then the heating system can be refilled with demineralized water, but the treatment capacity is limited and frequent cartridge changes are required for large systems
Solution Approach 1:
The system is segmented into two distinct filling paths: one through a water treatment cartridge for small systems/make-up water, and another through an adapter with external stationary cartridge for large systems/initial filling. This segmentation allows each component to be optimized for its specific function while providing overall system versatility.
Solution Approach 2:
The filling fitting is designed with universal adaptability by incorporating both a water treatment cartridge interface and an adapter interface with hose connections. This multi-functionality enables the same filling fitting to serve both small and large heating systems, as well as both initial filling and make-up water requirements.
2Quantity of substance
If an adapter with hose connections is used for initial filling of large heating systems, then the treatment capacity is sufficient, but the system becomes more complex and requires additional components
Solution Approach 1:
The adapter serves as an intermediary component that bridges the filling fitting and external stationary cartridge. It provides threaded receptacles for standard hose connection nipples, creating a simple interface that connects the water supply to the external cartridge without requiring complex integration.
Solution Approach 2:
The adapter utilizes inexpensive standard hose connection nipples as reusable components that can be easily attached and detached. These standard parts are widely available and can be replaced if needed, reducing the overall system cost and complexity while maintaining functionality.
3Ease of operation
If the hose connections are arranged angularly offset, then they are easily accessible and visually distinguishable, but the adapter design becomes more complex
Solution Approach 1:
The hose connections are arranged in an asymmetric angular offset configuration rather than a symmetric aligned arrangement. This asymmetry provides several benefits: the connections become easily accessible from different directions, the inlet and outlet are visually distinguishable, and hoses can be routed more easily without interference. The angular offset is achieved through simple geometric positioning in the adapter design.
