Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate charging station with integrated cooling is used, then battery temperature control is achieved, but device cost increases and operational flexibility decreases
Solution Approach 1:
The patent combines the vacuum generator, battery cooling system, and charging function into a single integrated vacuum cleaner unit. The vacuum generator serves dual purposes: generating suction for cleaning and providing forced convection cooling for battery temperature control during charging or discharging operations.
Solution Approach 2:
The vacuum generator is designed to perform multiple functions: it generates air flow for the vacuum cleaning function and simultaneously provides temperature control for the battery pack. This multi-functional approach eliminates the need for separate cooling fans or charging stations, reducing overall system complexity.
2Temperature
If a separate cooling fan is used for battery cooling, then temperature control is achieved, but device complexity and cost increase
Solution Approach 1:
