Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated installation is used for flat heat pipes, then production efficiency is improved, but shape deformation occurs and product quality stability deteriorates
Solution Approach 1:
The patent inverts the conventional sequence by first installing round heat pipes and then shaping them to flat configuration. This inversion allows automated installation of the round heat pipes (which are easier to handle) followed by a controlled shaping process, thereby achieving both high automation and shape stability.
Solution Approach 2:
The patent performs the installation action in advance using round heat pipes before the shaping action. By preliminarily installing the round heat pipes in their stable circular form and then applying the shaping process, the method ensures that automation can be used during installation while the final flat shape is achieved in a controlled manner.
2Reliability
If aging test temperature is reduced for flat heat pipes, then product quality is maintained, but production capacity decreases due to increased aging time
Solution Approach 1:
The patent performs the shaping action after the aging test. By preliminarily completing the installation with round heat pipes and then performing aging tests on the round configuration (which maintains structural integrity), the final shaping to flat configuration occurs after testing, thus maintaining both quality and production capacity.
3Measurement precision
If helium pressure is increased for flat heat pipes, then detection accuracy is improved, but shape deformation occurs and product quality stability deteriorates
Solution Approach 1:
The patent inverts the sequence by performing the helium inspection on the round heat pipe configuration before shaping. This allows high-pressure helium testing to be conducted on the structurally stronger round form, achieving high detection accuracy without causing shape deformation in the final flat configuration.

AI summary
A manufacturing method of three dimensional heat dissipation device includes a step of manufacturing a thermally conductive casing, a step of manufacturing a preliminary three dimensional heat dissipation device and a step of manufacturing a final three dimensional heat dissipation device. The step of manufacturing a thermally conductive casing is to manufacture the thermally conductive casing with an airtight chamber. The step of manufacturing a preliminary three dimensional heat dissipation device is to install at least one round heat pipe on the thermally conductive casing to form the preliminary three dimensional heat dissipation device. The step of manufacturing a final three dimensional heat dissipation device is to fix the preliminary three dimensional heat dissipation device and shape the round heat pipe to a flat heat pipe via a shaping tool so as to form the final three dimensional heat dissipation device.
