Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional heating element is used, then the device structure is simple, but the heat transfer efficiency to the surrounding air is poor
Solution Approach 1:
A heat distribution element is introduced as an intermediary between the heating element and the surrounding air. This heat distribution element has a large surface area that absorbs heat from the heating element and transfers it to the air, significantly improving heat transfer efficiency while maintaining relatively simple device structure
Solution Approach 2:
The heat distribution element extends in the vertical dimension with a large surface area, transforming the heat transfer from a point-source model to a distributed surface model, thereby enhancing the efficiency of heat transfer to the surrounding air
2Loss of energy
If the heat distribution element surface area is increased, then heat transfer efficiency improves, but the device volume increases
Solution Approach 1:
The heat distribution element utilizes the vertical dimension extensively, creating a tall, narrow structure rather than a wide, short one. This allows achieving large surface area for heat transfer without proportionally increasing the horizontal footprint and overall device volume
Solution Approach 2:
The heat distribution element is positioned locally around the heating element where heat generation occurs, concentrating the heat transfer function in a specific region rather than distributing it throughout the entire device volume, thus improving efficiency without unnecessary volume increase
