Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If only a fan and heat dissipation fins are used for heat dissipation, then the device structure remains simple, but the heat dissipation efficiency is inadequate
Solution Approach 1:
The radiator body is divided into multiple fins that extend from the first air inlet toward the air outlet, creating multiple heat exchange surfaces. This segmentation increases the heat dissipation area without significantly increasing overall device complexity, as the fins are integrated into the radiator body structure.
Solution Approach 2:
The patent introduces a third lateral side with a second air inlet, adding a dimensional aspect to the heat dissipation structure. This creates a three-dimensional heat exchange pathway where air can enter from multiple directions (first lateral side and third lateral side) and exit from the opposite second lateral side, significantly improving heat dissipation efficiency.
2Loss of energy
If the second air inlet is positioned between the geometrical middle side and the first lateral side, then the heat exchange area and time are increased, but the device structure becomes more complex
Solution Approach 1:
The second air inlet is specifically positioned between the geometrical middle side and the first lateral side of the radiator body, creating a localized optimization of the heat exchange structure. This strategic positioning ensures that the second air current has optimal interaction with the fins, maximizing heat exchange area and time in that specific region without complicating the overall device structure.
3Loss of energy
If multiple air inlets and fins are incorporated to enhance heat dissipation, then heat dissipation efficiency improves, but the device occupies more space
Solution Approach 1:
The multiple fins are nested within the radiator body, with each fin extending from the first air inlet toward the air outlet. This nested arrangement allows multiple heat exchange surfaces to be contained within a compact volume, improving heat dissipation efficiency without proportionally increasing the device volume.
Solution Approach 2:
By adding the third lateral side with the second air inlet, the patent utilizes three-dimensional space more efficiently. The air flow paths are arranged in different spatial dimensions, allowing enhanced heat dissipation within a compact footprint by exploiting vertical and lateral space rather than only horizontal expansion.

Implementation Method 1
The radiator is disposed inside the case and is in thermal contact with the heat source
Implementation Method 2
The air current generator generates a first air current flowing from the first air inlet of the body toward the air outlet of the body
Implementation Method 3
By the difference between the pressure inside the body and the pressure outside the case, the first air current sucks a second air current outside the case
