Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate connection box is provided for each heating circuit with four lines connected externally, then each heating circuit can be independently controlled, but the installation effort and complexity increase significantly
Solution Approach 1:
The patent merges the connection points for all four lines (supply line, drain line, flow line, and return line) into a single connection box located in the technical room. This centralization consolidates multiple external connections into one integrated unit, significantly reducing installation complexity while maintaining independent control capability for each heating circuit through internal valve mechanisms.
Solution Approach 2:
The connection box serves as an intermediary device that mediates between the multiple heating circuits and the central heating system. It provides a centralized interface where all four lines converge, allowing for simplified external connections while enabling complex internal control functions through integrated control valves for each circuit.
2Ease of manufacture
If four lines are connected to each heating circuit at separate external points, then each line can be individually accessed, but the installation time and effort increase
Solution Approach 1:
The patent combines all four line connections into a single centralized connection box, reducing the number of separate external connection points from four to one. This merging of connection points dramatically reduces installation time and effort while maintaining individual line accessibility through internal access points and control mechanisms within the box.
3Ease of operation
If control valves are installed externally for each heating circuit, then temperature control is achievable, but the system requires electrical energy and increases device complexity
Solution Approach 1:
The patent implements self-service temperature control through control valves that operate autonomously without external electrical energy. These valves are equipped with actuators that automatically regulate the opening degree based on temperature feedback, enabling the system to self-regulate heat distribution across different circuits without requiring external power sources or complex electrical control systems.
