Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If copper material is used for heat dissipation unit, then heat conduction speed is improved, but yield strength decreases after high-temperature processing and deformation resistance worsens
Solution Approach 1:
The patent changes the material parameter from copper to titanium alloy, fundamentally altering the material properties. Titanium alloy maintains high strength after high-temperature processing unlike copper whose crystalline grains coarsen and reduce yield strength. This parameter change resolves the contradiction by selecting a material that inherently resists strength degradation during thermal processing while providing adequate heat conduction for dissipation purposes.
Solution Approach 2:
The patent employs titanium alloy as a composite material solution that combines multiple desirable properties: high strength, corrosion resistance, and adequate heat conduction. The titanium alloy structure provides both structural integrity and thermal management capabilities, resolving the contradiction between needing fast heat conduction and maintaining yield strength after processing.
2Length of moving object
If copper foil is used to meet slimming requirements, then device thickness is reduced, but supporting strength and deformation resistance deteriorate
Solution Approach 1:
The patent changes the material parameter from copper foil to titanium alloy, which fundamentally alters the strength-to-thickness ratio. Titanium alloy's inherently higher strength allows the heat dissipation unit to be made thinner while maintaining sufficient supporting strength, thus resolving the contradiction between slimming requirements and structural integrity.
Solution Approach 2:
The heat dissipation unit is segmented into multiple components including titanium alloy plates, metal mesh, and sealing structures. This segmentation allows each component to be optimized independently - the titanium alloy provides structural strength in a thin profile, the metal mesh enhances heat dissipation surface area, and the sealing structures ensure integrity, collectively resolving the thickness-strength contradiction.
3Strength
If titanium alloy is used for heat dissipation unit, then strength and corrosion resistance are improved, but processability and shapeability worsen
Solution Approach 1:
The patent applies preliminary actions in the manufacturing process including surface treatment, anodization, and precise cutting before assembly. These preliminary preparations make the titanium alloy more amenable to subsequent assembly operations. The surface treatments create better bonding interfaces, and pre-cutting components to precise dimensions reduces the difficulty of final assembly, thus improving overall processability while maintaining titanium's strength advantages.
Solution Approach 2:
The manufacturing process is segmented into distinct stages: surface preparation, component fabrication, assembly, and sealing. This segmentation allows each stage to be optimized independently - surface treatments are applied to improve bonding, components are pre-fabricated with precise dimensions, and assembly uses controlled joining methods. This segmented approach makes titanium alloy manufacturing more manageable and improves ease of manufacture.
4Loss of energy
If traditional metal materials are used in harsh environments, then basic heat dissipation function is maintained, but reliability and durability worsen due to corrosion and environmental degradation
Solution Approach 1:
The patent changes the material parameter from traditional metals (copper, aluminum, stainless steel) to titanium alloy, which fundamentally improves environmental durability. Titanium alloy's natural oxide layer provides excellent corrosion resistance in harsh environments including corrosive, high-humidity, salty, and extreme temperature conditions. This parameter change maintains heat dissipation efficiency while dramatically improving reliability in harsh environments.
Solution Approach 2:
The patent employs titanium alloy as a durable, long-lasting material that eliminates the need for frequent replacement or maintenance in harsh environments. While titanium alloy has higher initial cost, its exceptional corrosion resistance and durability in corrosive, high-humidity, and extreme temperature conditions ensure long-term reliability, effectively making the heat dissipation unit a permanent, maintenance-free component.

AI summary
A manufacturing method of heat dissipation unit is disclosed. The heat dissipation unit is mainly composed of two titanium metal plate bodies. The titanium metal plate bodies are heat-treated, whereby the titanium metal plate bodies can be mechanical processed, shaped and surface-modified. Accordingly, the titanium metal can be freely shaped and provide capillary attraction. In this case, the titanium metal plate bodies can be used as the material of the heat dissipation unit instead of the conventional copper plate bodies to greatly reduce the weight and enhance the heat dissipation performance.
