Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical machine uses a complex structural design with integrated cooling circuits and multiple components, then the functional performance and cooling efficiency are improved, but the device complexity and difficulty of maintenance increase
Solution Approach 1:
The electrical machine is divided into modular units including a stator module, rotor module, and housing module that can be independently assembled and disassembled. The dividing device enables separation of these modules without requiring complete disassembly of the entire machine, thus maintaining functional performance while reducing maintenance complexity
Solution Approach 2:
The housing serves multiple functions by integrating both structural support and cooling functions. The housing includes integrated cooling circuits that perform both structural containment and thermal management, reducing the need for separate dedicated cooling components and simplifying the overall device structure
2Productivity
If the electrical machine is designed with a compact integrated structure, then the productivity and assembly efficiency are improved, but the accessibility for maintenance and servicing deteriorates
Solution Approach 1:
The electrical machine incorporates a dividing device that enables dynamic reconfiguration of the machine structure during maintenance. The modules can be quickly assembled into a compact configuration for efficient manufacturing and shipping, then easily separated into an accessible configuration for maintenance and servicing operations
3Strength
If the electrical machine uses traditional integrated design without dividing devices, then the structural integrity is maintained, but the ease of manufacture and servicing deteriorates
Solution Approach 1:
The machine is segmented into modular components connected by a dividing device that maintains structural integrity during operation. The dividing device includes connection elements that ensure strong, reliable joints between modules while enabling easy separation for manufacturing and assembly processes
Solution Approach 2:
Individual modules are pre-assembled and tested separately before final integration into the complete electrical machine. This preliminary assembly of modular units simplifies the overall manufacturing process, allows for quality control at each stage, and maintains structural integrity through standardized connection interfaces
