Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flange specifications are changed, then the adaptability is improved, but the device complexity increases because many processes with jigs have to be modified
Solution Approach 1:
The blower motor is divided into two independent parts: a standardized motor assembly and a flange. The motor assembly maintains fixed specifications and standardized manufacturing processes, while the flange can be independently modified to match different specifications. This segmentation allows flange specification changes without affecting the motor assembly or requiring modifications to existing manufacturing jigs and processes.
2Adaptability or versatility
If the flange specifications are changed, then the adaptability is improved, but the manufacturing cost increases due to process modifications
Solution Approach 1:
By segmenting the blower motor into a standardized motor assembly and a separate flange, the invention enables independent production of these components. The motor assembly can be manufactured using existing standardized processes without modification, while only the flange requires customization for different specifications, thereby reducing overall manufacturing costs.
Solution Approach 2:
The standardized motor assembly serves as a universal component that can be coupled with different flange specifications. This multi-functionality allows the same motor assembly to be used across various applications by simply changing the flange, reducing the need for multiple specialized manufacturing processes and lowering costs.
3Device complexity
If components are coupled to the motor assembly after it is coupled to the flange, then the assembly sequence is simplified, but the manufacturing precision decreases when flange specifications change
Solution Approach 1:
The invention reverses the conventional assembly sequence by first coupling components to the standardized motor assembly, then coupling the motor assembly to the flange. This segmentation approach ensures that the motor assembly maintains consistent manufacturing precision through standardized processes, while the flange coupling occurs at a later stage when specification variations are already accounted for.
