Compact Mixer-Diverter Valve Block for Solar Boiler Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve assemblies for combined systems that integrate solar panels and gas boilers are bulky and aesthetically unpleasing due to the need for separate installations of temperature sensors and mixing valves, leading to increased dimensions and unsightly installations.
Innovation Solution
A compact valve assembly that integrates a mixer and diverter valve within a single block casing, allowing for complete accommodation within the gas boiler casing, reducing dimensions and improving aesthetics by incorporating all necessary elements into a single, easily mountable and dismountable unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If temperature sensors and mixing valves are installed separately on pipes near the gas boiler, then the system can perform temperature control and water mixing functions, but the overall dimensions of the heating apparatus increase and the appearance becomes unsightly
Solution Approach 1:
The patent combines the temperature sensor, mixing valve, and diverter valve into a single integrated valve assembly that is mounted directly on the gas boiler. This merging of previously separate components into one unified structure reduces the overall space required while maintaining all necessary temperature control and water diversion functions.
Solution Approach 2:
The integrated valve assembly serves multiple functions simultaneously: it acts as a temperature sensor housing, a mixing valve mechanism, a diverter valve assembly, and a mounting structure. This multi-functionality eliminates the need for separate installations of each component, thereby reducing the overall dimensions of the heating apparatus.
2Ease of manufacture
If temperature sensors and mixing valves are enclosed in a separate box under the boiler, then the components are protected and organized, but the dimensions of the heating apparatus increase and the appearance becomes unsightly
Solution Approach 1:
Instead of enclosing components in a separate external box, the patent integrates all components into a single compact valve assembly that is mounted directly on the boiler body. This eliminates the need for an additional external enclosure while maintaining proper component organization and protection.
Solution Approach 2:
The valve assembly is designed with nested components where the temperature sensor is housed within the same structure as the mixing and diverter valves. This nesting arrangement allows all components to be compactly organized within a single integrated unit that attaches directly to the boiler, avoiding the need for a separate external box.
3Ease of repair
If multiple devices are individually installed on pipes near the gas boiler, then each device can be independently maintained and replaced, but the installation becomes complex and the overall dimensions increase
Solution Approach 1:
The valve assembly is designed as a modular integrated unit where the mixing valve and diverter valve are combined in a single assembly that can be installed and maintained together. This segmentation into a unified module reduces installation complexity while allowing the entire assembly to be replaced as a single unit if needed.

AI summary
A combined system (10) for the production of hot water which comprises : a solar apparatus (11); a wall -mounted gas boiler (13); a hydraulic network (14); and a mixer/diverter valve assembly (15; 15*; 15**; 15***). The system (10) is characterized in that the mixer/diverter valve assembly (15; 15*; 15**; 15***) is substantially contained as a whole in the casing (20) of the second apparatus (13). Furthermore, the valve assembly (15; 15*; 15**; 15***) is compact and comprises circuit elements (EL1, EL2, EL3, EL4) reciprocally interconnected so as to form a single block.
