Solution Overview
Problem
The existing hydraulic assemblies for combined wall-mounted boilers are costly and large due to customized component designs, leading to long depreciation times that do not align with the short lifespan of the products.
Innovation Solution
A hydraulic assembly for a combined system for room heating and domestic hot water production that features a compact design with a secondary heat exchanger positioned either in front or rear of the hydraulic return and delivery valve assemblies, reducing the need for custom molds and equipment, and integrating key components like a centrifugal pump assembly, expansion tank, and safety valves within a unified support body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If customized component designs are used for hydraulic assemblies, then functional requirements are met, but production costs and device size increase
Solution Approach 1:
The support body is designed as a universal component that can accommodate different arrangements of valve assemblies (front or rear positioning of secondary heat exchanger) and integrate multiple hydraulic functions within a single standardized structure, eliminating the need for customized designs for each functional configuration
Solution Approach 2:
The hydraulic assembly is divided into modular components (support body, valve assemblies, heat exchanger) that can be independently manufactured and then assembled in different configurations, allowing standardization of the support body while maintaining functional adaptability
2Adaptability or versatility
If customized component designs are used for hydraulic assemblies, then functional requirements are met, but depreciation time increases
Solution Approach 1:
The standardized support body serves multiple functional configurations through universal mounting interfaces and adaptable internal structures, allowing the same component to be used across different boiler models and configurations, thereby extending its service life and reducing depreciation time
3Adaptability or versatility
If complex component arrangements are used, then hydraulic functions are achieved, but assembly process complexity increases
Solution Approach 1:
Multiple valve assemblies and the secondary heat exchanger are integrated within a single support body structure, combining several hydraulic functions into one unified assembly that reduces the number of separate components and simplifies the overall assembly process
Solution Approach 2:
The assembly is segmented into standardized modules (support body, valve units, heat exchanger) with defined interfaces, allowing for systematic assembly procedures that reduce complexity compared to custom-integrated designs
