Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the area of a single processor is increased to improve processing capability, then the processing capability is improved, but the total pressure load on the CPU increases and bonding between the heat sink and CPU becomes insufficient
Solution Approach 1:
The patent introduces an elastic mechanical part (compression spring) that converts elastic force into dynamic pressure on the CPU. The spring mechanism allows the system to adapt to the increased pressure load by providing continuous elastic pressure, ensuring the heat sink maintains tight bonding with the CPU despite the larger processor area and higher power consumption.
Solution Approach 2:
The patent changes the physical state of the mechanical part from rigid to elastic by using a compression spring. This parameter change allows the fastening structure to transform elastic potential energy into mechanical pressure, effectively increasing the bonding strength between the heat sink and the high-power CPU without requiring larger fastening components.
2Power
If the area of a single processor is increased to improve processing capability, then the processing capability is improved, but heat dissipation capability becomes insufficient
Solution Approach 1:
The elastic mechanical part provides dynamic pressure that ensures continuous thermal contact between the heat sink base and the CPU surface. This elastic pressure compensates for any surface irregularities or thermal expansion, maintaining optimal heat transfer pathways even as the CPU generates more heat due to increased processing capability.
Solution Approach 2:
The elastic mechanical part acts as an intermediary between the heat sink structure and the CPU, transferring both mechanical pressure and thermal energy. The compression spring ensures intimate contact between the heat sink base and CPU surface, facilitating efficient heat transfer from the high-power processor to the heat dissipation system.
3Power
If the area of a single processor is increased to improve processing capability, then the processing capability is improved, but contact reliability between the CPU and processor slot decreases
Solution Approach 1:
The elastic mechanical part introduces dynamic adaptability to the fastening system, allowing it to maintain consistent contact pressure on the CPU's contact points with the processor slot. The compression spring compensates for manufacturing tolerances and thermal effects, ensuring reliable electrical and mechanical contact despite the larger CPU area and increased complexity.

AI summary
In a processor fastening structure, when a compression spring (23) is compressed by shortening a distance between the other end of a screw (24) and a heat sink base (22), the compression spring (23) provides elastic force for both the screw (24) and the heat sink base (22). In addition, because the screw (24) passes through the compression spring (23) to connect to a fastening assembly (21), the elastic force of the compression spring (23) is converted into pressure from the heat sink base (22) to a CPU.
