Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the rotor is directly connected to the inner tub to transfer rotary power, then the driving efficiency is improved, but the vibration transfer to peripheral parts increases
Solution Approach 1:
A vibration mitigation part is introduced as an intermediary component between the rotor and the inner tub. This mediator absorbs and reduces the vibration generated by the rotor during rotation, while still allowing the rotary power to be effectively transferred to the inner tub. The vibration mitigation part acts as a buffer that decouples the harmful vibration from the power transmission path.
2Stability of the object's composition
If the stator is directly connected to the bearing unit for structural support, then the structural stability is improved, but the vibration transfer from stator to bearing unit increases
Solution Approach 1:
A vibration mitigation part is positioned between the stator and the bearing unit to serve as an intermediary. This component maintains the structural connection while filtering out vibration transfers. The vibration mitigation part allows the stator to remain structurally stable while preventing the propagation of vibrations to the bearing unit.
3Manufacturing precision
If rigid connections are used between bearing units for precise support, then the positioning accuracy is improved, but the vibration transmission between bearing units increases
Solution Approach 1:
Vibration mitigation parts are installed between the upper and lower bearing units as intermediary elements. These parts maintain the precise positioning and support function of the bearing units while introducing vibration-damping characteristics. The mitigation parts allow the bearing units to remain accurately positioned while reducing the transmission of vibrations between them.
4Device complexity
If direct connection between rotor and inner tub is used, then the device complexity is reduced, but the noise generated increases
Solution Approach 1:
A vibration mitigation part is introduced between the rotor and the inner tub as a simple intermediary component. This addition minimally increases device complexity while effectively reducing the noise generated by vibration. The mitigation part serves as a vibration-damping element that breaks the direct vibration path without requiring complex structural modifications.
