Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling ducts are integrated into the frame body, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The cooling ducts are integrated directly into the frame body, merging the cooling system with the structural frame. This eliminates the need for separate cooling components and reduces overall device complexity while maintaining effective cooling functionality.
Solution Approach 2:
The frame body serves multiple functions: it provides structural support and simultaneously houses the cooling ducts. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while improving cooling efficiency.
2Strength
If plug-in pieces are used to connect frames, then mechanical stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The plug-in pieces are designed with tolerance compensation features that anticipate and accommodate manufacturing variations. This pre-built compensation mechanism reduces the impact of manufacturing precision limitations while maintaining strong mechanical connections.
Solution Approach 2:
The plug-in connection design incorporates adjustable parameters and tolerance ranges that allow for variation in manufacturing precision. By designing the connection to accommodate a range of dimensional variations, the system maintains mechanical stability without requiring extremely tight manufacturing tolerances.
3Loss of energy
If cooling ducts extend into plug-in pieces, then heat transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The cooling ducts are extended into the plug-in pieces, merging the cooling pathway with the mechanical connection structure. This integration improves heat transfer efficiency by placing cooling channels directly in the heat path, while simultaneously reducing device complexity by eliminating separate cooling components.
Solution Approach 2:
The plug-in pieces serve dual functions: mechanical connection between frames and heat transfer conduit. This multi-functionality improves heat transfer efficiency while reducing the number of separate components, thereby reducing overall device complexity.
4Reliability
If frames are designed for vibration resistance, then reliability is improved, but device complexity increases
Solution Approach 1:
Vibration resistance features are integrated into the basic frame structure and plug-in connections rather than being separate components. This merging of vibration protection into the structural design improves reliability while minimizing increases in device complexity.
Solution Approach 2:
The frame structure is designed to simultaneously provide mechanical support, vibration resistance, and housing for cooling ducts. This multi-functionality improves vibration resistance and reliability while avoiding the need for separate vibration protection components.
