Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional pressing and deformation methods are used to connect radiating fins to channels, then the fins can be integrated to the main body, but the junction becomes irregular and heat transfer efficiency is reduced
Solution Approach 1:
The radiating fins are pre-formed with folded root sections that match the connection channels before assembly. This preliminary preparation ensures that when the fins are inserted into the channels, they form regular, precise junctions without requiring subsequent deformation or pressing operations, thereby maintaining both manufacturing precision and heat transfer efficiency
Solution Approach 2:
The deformation and pressing steps that cause irregular junctions are removed from the manufacturing process. Instead of pressing fins into channels and deforming them, the invention extracts these harmful steps and replaces them with a simple insertion process using pre-formed folded root sections, eliminating the source of junction irregularity
2Strength
If guide grooves are pressed to deform channels for tightening fins, then fins can be securely connected, but channel deformation causes fin detachment risk
Solution Approach 1:
The folded root sections are pre-formed on the radiating fins to match the connection channels exactly. This preliminary action creates a secure fit through precise geometric matching rather than deformation, ensuring both connection strength and reliability without the risk of fin detachment
Solution Approach 2:
Instead of using deformation as the connection mechanism (which causes harm through channel distortion and fin detachment risk), the invention converts the benefit of geometric matching into the connection mechanism. The folded root sections are designed to match the channels precisely, transforming the potential harm of deformation into the benefit of precise geometric interlocking
3Ease of manufacture
If conventional manufacturing processes are used, then fins can be connected to the main body, but the manufacturing process is lengthy and productivity is reduced
Solution Approach 1:
The folded root sections are pre-formed on the radiating fins during fin manufacturing, preparing them for direct insertion into connection channels. This preliminary action eliminates the need for subsequent pressing, deformation, or tightening operations, simplifying the manufacturing process and significantly increasing productivity
Solution Approach 2:
The lengthy pressing and deformation steps are removed from the manufacturing process. The invention extracts these time-consuming operations and replaces them with a simple insertion process, thereby simplifying manufacturing and increasing production speed
4Strength
If channels are deformed to tighten fins, then fins can be secured to the main body, but fin density is reduced due to channel spacing requirements
Solution Approach 1:
The folded root sections are pre-formed to match the connection channels, enabling direct insertion without deformation. This allows channels to be placed closer together since no deformation space is needed, thereby increasing fin density while maintaining secure connections through precise geometric matching
Solution Approach 2:
The connection mechanism changes from deformation-based to geometric-matching-based. This parameter change allows channels to be positioned closer together since they don't require deformation space, thereby increasing the number of fins that can be accommodated on the main body

AI summary
A heat sink structure and a manufacturing method thereof. The heat sink includes a main body and multiple radiating fins each having a folded root section. The main body has multiple connection channels formed on a circumference of the main body. The multiple radiating fins are placed in a mold. A mechanical processing measure is used to high-speed impact the main body so as to thrust the main body into the mold. Accordingly, the folded root sections of the radiating fins are relatively high-speed thrust into the connection channels of the main body to tightly integrally connect with the main body.
