Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different sizes of molds are manufactured for different sizes of magnetic components, then the magnetic component can be tightly and securely assembled with the case, but the manufacturing cost is increased
Solution Approach 1:
The case is designed with a universal structure that can accommodate magnetic components of different sizes using the same mold. The case includes a receiving space with a bottom wall and side walls that can adapt to various magnetic component dimensions, eliminating the need for multiple size-specific molds while maintaining secure assembly through consistent structural features.
Solution Approach 2:
The invention changes the dimensional parameters of the receiving space within the case to accommodate different magnetic component sizes. By adjusting the size of the receiving space and the adhesive application area, the same case mold can produce cases that fit various magnetic component dimensions, resolving the contradiction between assembly security and manufacturing cost.
2Reliability
If the size of the case is varied with the change of the size of the magnetic component, then the magnetic component can be tightly assembled with the case, but the universality of the fan rotor mechanism is reduced
Solution Approach 1:
The case is designed as a universal component that can accommodate magnetic components of different sizes through a standardized structure with adjustable receiving spaces. This universal case design maintains assembly tightness across different magnetic component sizes while enhancing the versatility and interchangeability of the fan rotor mechanism.
Solution Approach 2:
The case structure is segmented into functional zones including a receiving space, side walls, and an adhesive application area. This segmentation allows the same case mold to produce cases that can adapt to different magnetic component sizes by adjusting which zones are utilized, maintaining assembly tightness while improving universality.
3Reliability
If press fit assembly is used for magnetic components of different sizes, then secure assembly is achieved, but different mold sizes are required increasing complexity
Solution Approach 1:
The case incorporates a universal press-fit structure with a standardized outer diameter and engagement features that work with magnetic components of different sizes. This universal design allows the same mold to produce cases that securely assemble various magnetic components through press fit, eliminating the need for multiple mold sizes and reducing overall system complexity.
Solution Approach 2:
The invention utilizes parameter changes in the internal receiving space dimensions while maintaining constant external case dimensions. This allows the same mold to produce cases with varying internal volumes that can accommodate different magnetic component sizes, maintaining press-fit assembly security without increasing mold variety or device complexity.

AI summary
A fan rotor mechanism includes a fan impeller, a case and an adhesive body. The fan impeller has a hub and multiple fan blades. The hub has a first top section and a first peripheral section together defining a receiving space for receiving the case. The case has a receptacle for receiving therein at least one magnetic component. The case and the magnetic component define therebetween a filling gap. The case is formed with at least one perforation in communication with the filling gap. The adhesive body is filled up in the filling gap. By means of the structural design of the fan rotor mechanism, the fan rotor mechanism is applicable to various magnetic components with different sizes. Therefore, is unnecessary to manufacture different sizes of molds for different sizes of cases so that the fan rotor mechanism has high universality and is manufactured at lower cost.
