Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fan is used to cool the coil part, then the coil part can be cooled, but the power supply efficiency is reduced due to additional energy consumption and mechanical complexity
Solution Approach 1:
The invention extracts the cooling function from a separate mechanical system (fan) and integrates it directly into the coil structure itself. The coil channels are designed to allow coolant flow through the winding gaps, enabling the coil to cool itself passively without external mechanical cooling devices, thus reducing device complexity while maintaining effective cooling.
Solution Approach 2:
The coil structure is designed to perform its own cooling function through integrated coolant channels within the winding gaps. The coil serves dual purposes: electromagnetic energy transmission and self-cooling, eliminating the need for separate cooling systems and reducing overall device complexity.
2Productivity
If the coil part is cooled more efficiently, then power supply efficiency is improved, but the system becomes more complex
Solution Approach 1:
The invention merges the cooling function with the coil structure by integrating coolant channels directly into the winding gaps. This combination allows the coil to perform both electromagnetic energy transmission and thermal management functions simultaneously, improving power supply efficiency through effective cooling without adding separate cooling system complexity.
Solution Approach 2:
The coil structure is designed with multi-functionality, serving both as the electromagnetic energy transmission element and as the cooling channel carrier. The winding gaps are utilized dual-purpose: maintaining electromagnetic performance and facilitating coolant flow for thermal management, thereby improving efficiency without increasing system complexity.
3Temperature
If coolant volume is increased to improve cooling, then cooling efficiency is improved, but the device size increases
Solution Approach 1:
The invention applies cooling locally where heat is generated most intensely. Coolant channels are positioned within the winding gaps of the coil, directly at the heat source, allowing efficient heat removal with minimal coolant volume. This localized cooling approach improves cooling efficiency without requiring large amounts of coolant or increasing overall device volume.
Solution Approach 2:
The cooling channels are integrated into the three-dimensional structure of the coil windings, utilizing the existing spatial arrangement of the windings. This dimensional integration allows coolant flow paths to be created within the existing coil geometry without adding external cooling components or increasing device volume.
