Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat pump systems for room heating and domestic hot water production have complex layouts with numerous pipes, making maintenance difficult due to the large number of single-function components and high costs.
Innovation Solution
A multifunctional hydraulic assembly that integrates key components such as the heat exchanger, auxiliary heater, pumping assembly, and filtering element into a compact design, reducing the number of pipes and simplifying maintenance by using a support body with tubular-shaped portions and unions to house these components, allowing for easier adaptation to different heat exchanger sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of single-function components are used to ensure specific functions, then the reliability is improved, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The patent combines multiple single-function components (heat exchanger, auxiliary heater, pumping assembly, filtering element) into a single integrated hydraulic assembly. This merging reduces the number of separate components and connection pipes while maintaining all necessary functions, thereby reducing system complexity and improving maintainability without sacrificing functional reliability
Solution Approach 2:
The hydraulic assembly is designed as a multifunctional unit that simultaneously performs heating, water circulation, and filtration functions. By making the assembly universal and capable of performing multiple functions within a single integrated structure, the patent reduces the overall system complexity while ensuring all necessary functions are maintained
2Reliability
If numerous pipes are used to connect single-function components, then the specific functions are ensured, but the layout dimensions increase and maintenance accessibility is reduced
Solution Approach 1:
By merging multiple components into a single hydraulic assembly with integrated internal connections, the patent eliminates the need for numerous external pipes and connection ducts. This significantly reduces the layout dimensions and improves accessibility for maintenance operations while maintaining all necessary functional connections
3Reliability
If multiple single-function components are used, then the functional requirements are met, but the manufacturing costs increase
Solution Approach 1:
The integration of multiple components into a single hydraulic assembly reduces the total number of parts that need to be manufactured, assembled, and connected. This merging approach simplifies the manufacturing process, reduces material requirements, and lowers overall production costs while maintaining all necessary functions
Solution Approach 2:
By designing a universal hydraulic assembly that performs multiple functions, the patent eliminates the need to manufacture and assemble separate components for each function. This multi-functional approach reduces manufacturing complexity and costs while ensuring all functional requirements are met
