Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal material is used for motor housing and shaft, then strength and stability are improved, but weight increases, production cycle lengthens, and cost increases
Solution Approach 1:
The patent uses a composite structure combining plastic material for the motor housing and metal material for the motor shaft. This allows the housing to be lightweight and easy to manufacture while the shaft maintains the necessary strength and stability for mechanical operation, thus resolving the contradiction between overall weight reduction and localized strength requirements.
2Reliability
If metal material is used for motor housing and shaft, then stability is improved, but production cycle lengthens and manufacturing cost increases
Solution Approach 1:
The motor is divided into separate components: a plastic housing that can be rapidly manufactured using injection molding, and a metal shaft that requires precision machining. This segmentation allows different manufacturing processes to be applied optimally to each component, with the plastic housing enabling faster production cycles while the metal shaft ensures operational stability.
Solution Approach 2:
The patent changes the material parameter of the housing from metal to plastic, which fundamentally alters the manufacturing process from machining-intensive to molding-intensive. This parameter change enables shorter production cycles through rapid molding while maintaining product stability through careful design of the plastic components and their assembly with metal parts.
3Ease of manufacture
If plastic material is used for motor housing, then production cost decreases and production cycle shortens, but strength and stability may be compromised
Solution Approach 1:
The patent employs composite construction where the plastic housing provides ease of manufacture and cost-effectiveness, while the metal shaft and internal metal components provide the necessary strength and mechanical stability. This composite approach allows each material to be used where it is most advantageous.
Solution Approach 2:
Different parts of the motor have different material qualities: the housing is made of plastic for ease of manufacture, while the shaft and bearing areas use metal for local strength requirements. This local differentiation of material quality ensures strength is provided only where mechanically necessary while maintaining overall manufacturing efficiency.
4Ease of manufacture
If plastic motor housing with separate bearing chamber is used, then manufacturing cost decreases, but assembly complexity increases and shaft stability during mounting deteriorates
Solution Approach 1:
The patent merges the bearing chamber with the motor housing into a single integrated plastic component. This eliminates the need for separate bearing chamber manufacturing and assembly, reducing both manufacturing steps and assembly complexity while maintaining the cost advantages of plastic manufacturing.
