Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of radiating fins is increased to enlarge heat dissipation area, then the heat dissipation area is improved, but the gap between adjacent radiating fins is reduced and airflow resistance is enlarged
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement of radiating fins to a three-dimensional spatial configuration by introducing varying heights and staggered positions. The first and second radiating fins extend in different directions from the heat dissipation base, creating vertical and horizontal dimensionality. This dimensional change allows airflow to pass through multiple levels and directions, reducing resistance while maintaining large heat dissipation area.
Solution Approach 2:
The patent employs asymmetric design where the first radiating fin and second radiating fin have different orientations, heights, and positions relative to the heat dissipation base. The first radiating fin extends in a first direction while the second radiating fin extends in a second direction that is different from the first direction. This asymmetry creates non-uniform airflow paths that reduce resistance compared to symmetric uniform arrangements.
2Area of stationary object
If the height or length of radiating fins is increased to enlarge heat dissipation area, then the heat dissipation area is improved, but the radiating fins become thin and are prone to deformation or damage
Solution Approach 1:
Instead of simply increasing the height or length of single-plane radiating fins, the patent introduces a three-dimensional configuration with radiating fins extending in multiple directions and at different heights from the base. This dimensional approach increases heat dissipation area without requiring excessive height in any single fin, thereby maintaining structural strength and resistance to deformation.
Solution Approach 2:
The heat dissipation structure is segmented into multiple independent radiating fins (first radiating fin, second radiating fin, etc.) that extend in different directions. Rather than using fewer, taller fins, the total heat dissipation area is divided into multiple shorter segments arranged spatially. This segmentation reduces the height requirement for each individual fin while achieving the same or greater total heat dissipation area, thereby improving structural strength.
3Area of stationary object
If two independent heat sinks are stacked to increase heat dissipation area, then the heat dissipation area is improved, but the upper heat sink applies pressure to the radiating fins of the lower heat sink causing deformation
Solution Approach 1:
The patent integrates multiple radiating fins extending in different directions and at different heights from a single heat dissipation base into one unified structure, rather than stacking separate heat sinks vertically. This three-dimensional integration achieves large heat dissipation area without the need for vertical stacking that would impose compressive loads on the lower fins, thereby maintaining their structural strength.
Solution Approach 2:
The patent merges multiple radiating fins (first radiating fin, second radiating fin, etc.) into a single integrated heat dissipation structure that shares a common base. This unified structure eliminates the need for separate stacked heat sinks, thereby removing the compressive pressure issue while maintaining the combined heat dissipation area of all fins working together.
4Strength
If the thickness of radiating fins is increased to improve structural strength, then the structural strength is improved, but the number of radiating fins is reduced and heat dissipation area decreases
Solution Approach 1:
The patent resolves this contradiction by moving from a two-dimensional planar arrangement to a three-dimensional spatial configuration. Multiple radiating fins with moderate thickness can be arranged in different directions and heights, increasing the total heat dissipation area without requiring increased thickness of individual fins. The spatial arrangement allows more fins to coexist with adequate spacing, maintaining both structural strength and large heat dissipation area.
Solution Approach 2:
The patent segments the heat dissipation function into multiple thin radiating fins arranged in different spatial directions rather than using fewer thick fins. Each fin maintains sufficient thickness for structural strength, while the segmented multi-directional arrangement achieves large total heat dissipation area. This segmentation allows optimization of individual fin thickness for strength while the collective arrangement maximizes surface area.

AI summary
A thermal module includes a base seat, at least two heat pipes and multiple heat dissipation units. Each heat pipe has a heat absorption end and a heat dissipation end outward extending from the heat absorption end. The heat absorption ends are disposed on the base seat. The heat dissipation ends of the at least two heat pipes are positioned above the base seat at different heights and misaligned from each other. The multiple heat dissipation units are connected with the heat dissipation ends of the heat pipes and arranged at intervals. By means of arranging the multiple heat dissipation unit at intervals as multiple layers, the heat dissipation areas is enlarged to prevent the airflow from being interrupted so as to effectively greatly enhance the heat dissipation efficiency.
