Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an electric cooling fan is used to cool the motor, then the motor cooling effect is improved, but the number of components and wiring increases
Solution Approach 1:
The cooling function is merged with the existing impeller component that is already integrated with the arm or speed reducer. The impeller serves dual purposes: maintaining mechanical operation and generating cooling airflow, thereby eliminating the need for a separate electric cooling fan and its associated wiring
Solution Approach 2:
The impeller utilizes the existing rotational motion from the arm or speed reducer to generate cooling airflow without requiring an additional power source. The system's own operational movement is harnessed to perform the cooling function, eliminating dependency on separate electrical components
2Temperature
If an electric cooling fan is used to cool the motor, then the motor cooling effect is improved, but the structural complexity increases
Solution Approach 1:
The cooling structure is combined with the existing arm or speed reducer assembly through the integrated impeller. This merging approach eliminates the need for separate cooling fan mounting structures, support brackets, and wiring routing paths, thereby simplifying the overall structural complexity
