Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional flow control methods are used for cooling and heating media, then the temperature adjustment capability is limited, but the device complexity increases due to the need for precise flow control mechanisms
Solution Approach 1:
The patent merges the cooling medium flow path and heating medium flow path into a single merging section where both fluids converge. The switching member integrates multiple functions: it controls the cooling medium flow path, the heating medium flow path, and the mixed fluid outflow path simultaneously. This consolidation reduces the number of separate control mechanisms needed while maintaining precise temperature adjustment capability through the single switching member's multi-position control.
2Measurement precision
If multiple separate flow control valves are used for precise flow volume control, then the temperature control precision improves, but the device complexity and number of components increase
Solution Approach 1:
The switching member is designed as a universal control element that performs multiple functions: it regulates the cooling medium flow path, controls the heating medium flow path, and manages the mixed fluid outflow path. By positioning the switching member to face different combinations of flow paths (one, two, or three paths simultaneously), a single component achieves what would traditionally require multiple separate control valves, thereby maintaining flow volume control precision while reducing component count.
3Device complexity
If the switching member connects only one flow path at a time, then the device simplicity is maintained, but the temperature adjustment flexibility is reduced
Solution Approach 1:
The switching member is designed with dynamic positioning capability, allowing it to face different numbers and combinations of flow paths depending on the required temperature adjustment. The member can be positioned to face one flow path for simple cooling or heating, two flow paths for mixed temperature control, or three flow paths for complex temperature adjustment scenarios. This dynamic adaptability enables flexible temperature control while maintaining relatively simple switching mechanism structure.

AI summary
A valve device for adjusting the flow volumes of a cooling medium and a heating medium for adjusting the temperature of an electronic device includes: flow paths through which a cooling medium and heating medium are able to flow; and a merging section into which these flow path merge. The merging section has a valve shaft internally and a first channel is formed in the valve shaft. The valve shaft makes the first channel face at least two of the flow paths so as to make at least two flow paths communicate with each other.
