Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large motor is used to provide sufficient blending power, then the blending performance is improved, but the device height increases making it difficult to store under kitchen cabinets
Solution Approach 1:
The motor design transitions from a traditional vertical orientation to a horizontal orientation, changing the dimension in which the motor's size is expressed. This allows the motor to provide sufficient power while maintaining a low profile height suitable for cabinet storage.
Solution Approach 2:
The motor's geometric parameters are optimized with a specific diameter-to-height ratio greater than 3:1, creating a compact, wide, and low profile configuration. This parameter change enables the motor to deliver high power output while minimizing the height dimension.
2Area of stationary object
If the motorized unit is designed with a compact size for individual portions, then the footprint and storage space are reduced, but the power and torque available for blending are insufficient
Solution Approach 1:
The motor redistributes its volume from a tall, narrow configuration to a short, wide configuration. This dimensional change allows the motor to maintain compact footprint and low profile while internally accommodating the necessary components for high power output.
Solution Approach 2:
The motor components are arranged in a nested configuration where the rotor is positioned within the stator assembly, maximizing space utilization. This nested arrangement enables high power density within the compact motor housing.
3Manufacturing precision
If the rotational speed is increased to achieve smaller particle size, then the blending quality is improved, but the motor requires higher power output which increases device size
Solution Approach 1:
The motor's rotational speed parameter is optimized to operate between 5000-25000 RPM, enabling the production of smaller particle sizes. The motor's geometric parameters are simultaneously optimized to deliver the necessary power at these high speeds without increasing device dimensions.
