Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an electric cooling fan is used to cool the motor, then the motor cooling function is improved, but the number of components and wiring increases
Solution Approach 1:
The cooling function is merged with the existing impeller component by attaching it to the rotating arm or speed reducer. The impeller utilizes the existing rotational motion to generate cooling airflow, eliminating the need for a separate electric cooling fan and its associated wiring, thus reducing component count while maintaining effective motor cooling
2Temperature
If an electric cooling fan is used to cool the motor, then the motor cooling function is improved, but the structural complexity increases
Solution Approach 1:
The cooling structure is integrated into the existing mechanical components. The impeller is attached to either the rotating arm or the speed reducer, utilizing their existing rotational motion. This merging approach eliminates the need for separate cooling fan mounting structures and wiring routing, thereby reducing structural complexity while achieving effective motor cooling
